PROPOSED CHANGES TO ONTARIO REGULATION 213/91, CONSTRUCTION PROJECTS, UNDER THE OCCUPATIONAL HEALTH AND SAFETY ACT FOR IMPROVING TOWER CRANE SAFETY

AS RECOMMENDED BY THE TOWER CRANE REGULATION REVIEW WORKING GROUP

CURRENT REQUIREMENT IN O. REG. 213/91 PROPOSED CHANGES RELATED TO TOWER CRANES RATIONALE/COMMENT RE: PROPOSED CHANGES

NO definition of “climbing” NEW DEFINITION

“climbing” means the process in which a tower crane working on or within a structure that is under construction, as the height of that structure increases, the tower crane is raised to a new working height by changing the elevation of the crane superstructure and includes top-climbing, bottom-climbing, internal climbing and telescoping.

A proposed definition of “climbing” is being added and is a combination of the definitions from the CSA standard Z248-04, Code for Tower Cranes, and the United States Occupational Safety and Health Administration (OSHA) Regulations.

The term “extending” a tower crane (terminology currently used in section 154 of the Construction Regulation) which has traditionally meant external “top-climbing” of a tower crane, is being replaced with “climbing” (as defined) to avoid confusion over the different types of “climbing”.

NO definition of “mobile crane” NEW DEFINITION

“mobile crane” means a mechanical device or structure that incorporates a boom that,(a) Is capable of moving in the vertical and horizontal plane,(b) Is capable of raising, lowering or moving a load suspended from

the boom by a hook or rope, and(c) Is mounted on a mobile base or chassis,

and includes a telescoping or articulated boom but does not include equipment that is used exclusively for fire-fighting or by automotive wreckers and tow trucks to clear wrecks and haul vehicles.

A proposed definition of “mobile crane” is being added, consistent with the one in O. Reg. 275/11, Scope of Practice –

Trades in the Construction Sector, under the Ontario College of Trades and Apprenticeship Act, 2009,

to clarify when particular requirements apply specifically to mobile cranes and not to other types of cranes e.g. operator qualifications specified under the OCTAA.

NO definition of “self-erecting tower crane” NEW DEFINITION

“self-erecting tower crane” means a tower crane that is capable of being erected without the use of ancillary equipment.

A proposed definition of “self-erecting tower crane” is being added for clarity and comes from the CSA standard Z248-04, Code for Tower Cranes.

May 15, 2013


“tower crane” means a travelling, fixed or climbing mechanical device or structure that has,(a) a boom, a jib or both,(b) a power-driven drum and wire rope to raise, lower or

move material, and(c) a vertical mast;

“tower crane” means a travelling, fixed or climbing mechanical device or structure that is of the travelling, fixed or climbing type and that has,(a) a boom, a jib or both,(b) a power-driven drum and wire rope to raise, lower or move

material, and(b) a vertical mast or tower.

Current definition of “tower crane” is revised slightly for clarity.

The term “tower crane” includes a self-erecting tower crane regardless of its lifting capacity.

11. (1) The following incidents are prescribed for the purpose of section 53 of the Act:

1. A worker falling a vertical distance of three metres or more.

2. A worker falling and having the fall arrested by a fall arrest system other than a fall restricting system.

3. A worker becoming unconscious for any reason.

4. Accidental contact by a worker or by a worker’s tool or equipment with energized electrical equipment, installations or conductors.

5. Accidental contact by a crane, similar hoisting device, backhoe, power shovel or other vehicle or equipment or its load with an energized electrical conductor rated at more than 750 volts.

6. Structural failure of all or part of falsework designed by, or required by this Regulation to be designed by, a professional engineer.

7. Structural failure of a principal supporting member, including a column, beam, wall or truss, of a structure.

8. Failure of all or part of the structural supports of a scaffold.

9. Structural failure of all or part of an earth- or water-retaining structure, including a failure of the temporary or permanent supports for a shaft, tunnel, caisson, cofferdam or trench.

10. Failure of a wall of an excavation or of similar earthwork with

11. (1) The following incidents are prescribed for the purpose of section 53 of the Act:

UNCHANGED EXCEPT FOR ADDITION OF ITEM 12.

May 15, 2013


respect to which a professional engineer has given a written opinion that the stability of the wall is such that no worker will be endangered by it.

11. Overturning or the structural failure of all or part of a crane or similar hoisting device. 12. Accidental or uncontrolled movement of a load or part of a load

or any failure of rigging suspended from a tower crane.

NEW Item 12 – A new incident is added for which a constructor would have to provide a written report to the Ministry and to a Joint Health and Safety Committee, health and safety representative or trade union, if any, within 2 days of the incident, setting out the circumstances of the occurrence and the steps taken to prevent a recurrence. There appears to be a recent increased incidence of suspended loads being dropped by cranes. Such incidents can have catastrophic results on workers and property. This addition would provide the Ministry an opportunity to follow up on particular incidents to determine whether they involved any violations of the Construction Regulation.

17. (1) A constructor shall establish for a project written procedures to be followed in the event of an emergency and shall ensure that the procedures are followed at the project.

(2) The constructor shall review the emergency procedures with the joint health and safety committee or the health and safety representative for the project, if any.

(3) The constructor shall ensure that the emergency procedures are posted in a conspicuous place at the project.

17. (1) A constructor shall establish for a project written procedures to be followed in the event of an emergency and shall ensure that the procedures are followed at the project.

NEW (1.1) If the emergency procedures include the use of a tower crane to move a worker or workers in a platform, basket, stretcher or other rescue device suspended from the crane, the requirements of (NEW) ss.153.1 shall be met.

(2) The constructor shall review the emergency procedures with the joint health and safety committee or the health and safety representative for the project, if any.

(3) The constructor shall ensure that the emergency procedures are posted in a conspicuous place at the project.

New ss.(1.1) – If a decision is made by the constructor and tower crane employer that the tower crane on a project could be used if necessary in the event of an emergency situation to rescue a worker from an elevated position on the building or structure under construction, then that must be clearly indicated in the emergency procedures and appropriate details provided. The constructor and employer would have to ensure that the tower crane and platform, basket, stretcher or other rescue device used to rescue a worker meet the requirements in NEW subsection 153.1.

102. No operator shall leave unattended the controls of,

(a) a front-end loader, backhoe or other excavating machine with its bucket raised;

(b) a bulldozer with its blade raised;

(c) a fork-lift truck with its forks raised; or

(d) a crane or other similar hoisting device with its load raised.

102. No operator shall leave unattended the controls of,

(a) a front-end loader, backhoe or other excavating machine with its bucket raised;

(b) a bulldozer with its blade raised;

(c) a fork-lift truck with its forks raised; or

(d) subject to s.164, a crane or other similar hoisting device with its load raised.

A cross reference to section 164 is added. S.64 is being changed to allow a load to be suspended from an unattended tower crane only if specified by the crane manufacturer.

Amended March 2013, came into effect April 8, 2013 to align with the Ontario College of Trades and Apprenticeship Act, 2009 coming into effect on the same date.

150. (1) Subject to subsection (2), no worker shall operate a crane or similar hoisting device unless the worker holds a certificate of qualification issued under the Ontario College of Trades and Apprenticeship Act, 2009, that is not suspended, or the worker is an apprentice and is working pursuant to a training agreement registered under that Act, that is not suspended, in the trade of,

(a) hoisting engineer — mobile crane operator 1, if the worker is operating a crane or similar hoisting device capable of raising, lowering or moving any material that weighs more than 30,000 pounds;

(b) hoisting engineer — mobile crane operator 1 or hoisting engineer — mobile crane operator 2, if the worker is operating a crane or similar hoisting device capable of raising, lowering or moving only material that weighs more than 16,000 pounds but no more than 30,000 pounds; or

(c) hoisting engineer — tower crane operator, if the worker is operating a tower crane.

150. (1) Subject to subsections (1.2) and (2), no worker shall operate a mobile crane or tower crane or similar hoisting device unless the worker holds a certificate of qualification issued under the Ontario College of Trades and Apprenticeship Act, 2009, that is not suspended, or the worker is an apprentice and is working pursuant to a training agreement registered under that Act, that is not suspended, in the trade of,

(a) hoisting engineer — mobile crane operator 1, if the worker is operating a crane or similar hoisting device capable of raising, lowering or moving any material that weighs more than 30,000 pounds;

(b) hoisting engineer — mobile crane operator 1 or hoisting engineer — mobile crane operator 2, if the worker is operating a crane or similar hoisting device capable of raising, lowering or moving only material that weighs more than 16,000 pounds but no more than 30,000 pounds; or

(c) hoisting engineer — tower crane operator, if the worker is operating a tower crane.

NEW (1.1) Subject to subsection (1.2), an apprentice operating a tower crane shall be constantly monitored during the operation of the crane by a person who:

(i) meets the requirements of ss.(1)(c),

(ii) is in direct audio communication with the apprentice,

(iii) is not engaged in performing other work while monitoring the apprentice who is operating the crane, and

(iv) is able to direct the apprentice during the operation of the crane.

1.1) Subsection (1) does not apply when a worker is using excavation equipment to place pipes into a trench.

Section 150 is revised to clarify that the operator qualifications specified under the Ontario College of Trades and Apprenticeship Act, 2009 apply only to operators of mobile cranes and tower cranes and not to any other types of cranes or hoisting devices.

In NEW subsection 150(1.1),o The monitor would not have to be in constant

visual contact of the apprentice operator since there may be situations when their views of each other are blocked by objects/structures on the construction site during the movement of a load by the crane.

o The term “during the operation of the crane” means while the apprentice is manipulating the controls of the crane and the controls are “ON”. The intent is for the monitor to be able to tell the apprentice to immediately stop the operation at any point should an unsafe situation develop.

o The reference to “not engaged in performing other work” in paragraph (iii) would allow the monitor to do work related to the hoisting operation e.g. guiding a load being moved or unhooking a load placed by the apprentice.

May 15, 2013


(1.1) Subsection (1) does not apply when a worker is using excavation equipment to place pipes into a trench.

(2) No worker shall operate a crane or similar hoisting device, other than one described in subsection (1), unless,

(a) the worker has written proof of training indicating that he or she is trained in the safe operation of the crane or similar hoisting device; or

(b) the worker is being instructed in the operation of the crane or similar hoisting device and is accompanied by a person who meets the requirements of clause (a).

(3) A worker shall carry his or her proof of training while operating a crane or similar hoisting device.

New (1.2) An operator of a self-erecting tower crane,

(a) rated more than 40 metre tonnes, shall hold a certificate of qualification issued under the Ontario College of Trades and Apprenticeship Act, 2009, that is not suspended in the trade of:

(i) hoisting engineer — mobile crane operator 1, or

(ii) hoisting engineer — tower crane operator, and

(b) rated up to and including 40 metre tonnes, shall hold a certificate of qualification issued under the Ontario College of Trades and Apprenticeship Act, 2009, that is not suspended in the trade of:

(i) hoisting engineer — mobile crane operator 1, or

(ii) hoisting engineer — mobile crane operator 2, or

(iii) hoisting engineer — tower crane operator, and

(c) shall have successfully completed the relevant modular training standard developed and administered by the Ministry of Training, Colleges and Universities for self-erecting tower crane operator.

(2) No worker shall operate a crane, other than one described in subsection (1), or similar hoisting device unless,

(a) the worker has written proof of training indicating that he or she is trained in the safe operation of the crane; or

(b) the worker is being instructed in the operation of the crane or similar hoisting device and is accompanied by a person who meets the requirements of clause (a).

(3) A worker shall carry his or her proof of training, or qualification issued under the Ontario College of Trades and Apprenticeship Act, 2009, while operating a crane or similar hoisting device.

Deleting existing subsection (1.1) does not change the current intent or implementation of the requirement. Subsection (1.1) is deleted because the Ministry has determined that excavation equipment used to place pipes into a trench is not a crane or a hoisting device similar to a crane, and section 150 is being changed so it would no longer apply to “similar hoisting device” i.e. it would only apply to mobile and tower cranes.

The NEW subsection (1.2) would make it mandatory for operators of self-erecting tower cranes to have completed the MTCU training programs for self-erecting tower cranes released in 2009. The specific titles and identifying numbers of the training programs are not included in the Regulation as they may be updated/changed at any time by MTCU.

151. (1) No crane or similar hoisting device shall be subjected to a load greater than its rated load-carrying capacity.

(2) The manufacturer of a crane or similar hoisting device or a professional engineer shall determine its rated load-carrying capacity in accordance with,

(a) for a mobile crane, Canadian Standards Association Standard Z150-1974 Safety Code for Mobile Cranes; and

(b) for a tower crane, Canadian Standards Association Standard Z248-1976 Code for Tower Cranes.

(3) Every crane or similar hoisting device shall have affixed to it a load rating plate,

(a) that the operator can read while at the controls; and

(b) that contains enough information for the operator to determine the load that can be lifted for each configuration of the crane.

(4) A luffing boom crane, other than a tower crane, shall have affixed to it a boom angle indicator that the operator can read while at the controls.

151. (1) No crane or similar hoisting device shall be subjected to a load greater than its rated load-carrying capacity.

(2) The manufacturer of a mobile crane or tower crane or similar hoisting device or a professional engineer shall determine its rated load-carrying capacity in accordance with, as appropriate , a) for a mobile crane, Canadian Standards Association Standard

Z150-1974 Safety Code for Mobile Cranes; and

(b) for a tower crane, Canadian Standards Association Standard Z248-1976 Z248–04 , Code for Tower Cranes.

(3) Every crane or similar hoisting device shall have affixed to it a load rating plate chart,

(a) affixed to it which the operator can read while at the controls of the crane;

(b) (NEW) with the operator of the crane if the crane is operated by remote control; and

(c) that contains enough information for the operator to determine the load that can be lifted for each configuration of the crane.

(4) A luffing boom crane, other than a tower crane, shall have affixed to it a boom angle indicator that the operator can read while at the controls of the crane.

ss.(151(2) – The revision is necessary since the referenced CSA standards apply only to mobile cranes and tower cranes and not to “similar hoisting devices”.

ss.(3) – The existing term, “load rating plate” is replaced with the term, “load rating chart” for consistency with the CSA standard Z248-04, Code for Tower Cranes. This same editorial change is made throughout the regulation to ensure consistency and would apply to all cranes. This revision would not change the existing intent or interpretation of the requirements.

ss.(4) - Deleting “other than a tower crane” means all luffing boom cranes, including luffing tower cranes, would need to have a boom angle indicator. This change reflects the changing technology of tower cranes since the initial introduction of this requirement in the Regulation. Industry experience indicates most new luffing tower cranes have digital boom angle indicators at the operator’s controls. Older cranes that do not have boom angle indicators may need to have them retrofitted in order to comply with this requirement.

152. (1) The owner of a crane or similar hoisting device shall keep a permanent record of all inspections of, tests of, repairs to, modifications to and maintenance of the crane or

152. (1) The owner of a crane or similar hoisting device shall keep a permanent written record of all inspections of, tests of, repairs to, modifications to and maintenance performed on the crane. or similar hoisting device.

Section 152 is revised based on CSA standard Z248-04, Code for Tower Cranes, Clause 6.2, to provide clarity regarding the creation and maintenance of the machine history of a crane and the crane’s log book. Although section 152 applies

similar hoisting device.

(2) The owner of a crane or similar hoisting device shall prepare a log book for it for use at a project that shall include the record referred to in subsection (1) covering the period that is the greater of,

(a) the immediately preceding twelve months; and

(b) the period the crane or similar hoisting device is on the project.

(3) The log book shall be kept with the crane or similar hoisting device.

(1.1) NEW The permanent written record referred to in subsection (1) shall:

(a) include the names and signatures of the persons who performed the inspections of, tests of, repairs to, modifications to and maintenance on the crane and the dates on which these were performed; and

(b) be considered a permanent part of a crane that is to be transferred to each subsequent new owner of the crane.

(2) (a) The owner of a crane or similar hoisting device shall prepare a log book for the crane or similar hoisting device while it is at a project.

(b) The log book shall include the written record referred to in subsection (1) for the crane covering at least the twelve months immediately preceding the project.

(2.1) NEW(a) For the duration of the project, the log book shall

permanently record all inspections of, tests of, repairs to, modifications to and maintenance performed on the crane or similar hoisting device; and

(b) The log book referred to in clause (a) shall include the names and signatures of the persons who performed the inspections of, tests of, repairs to, modifications to and maintenance on the crane and the dates on which these were performed.

(3) The log book shall be kept with the crane or similar hoisting device while the crane or similar hoisting device is on the project and shall be made available to an inspector upon request.

(3.1) NEW The record of all inspections of, tests of, repairs to, modifications to and maintenance performed on the crane or similar hoisting device referred to in subsection (2.1) shall be transferred from the log book to the owner’s permanent written record referred to in subsection (1).

generally to any crane and not just to tower cranes, the Tower Crane Regulation Review Working Group would like to recommend that industry consider these proposed requirements for all cranes and not just tower cranes. The revisions would not impose new obligations but would simply clarify in regulation what is routinely currently done in practice with respect to crane inspection/maintenance records by crane owners and crane users/operators while a crane is on a project.

May 15, 2013


(4) The owner of a crane or similar hoisting device shall retain and make available to the constructor on request copies of all log books and records for the crane or similar hoisting device.

(4) The owner of a crane or similar hoisting device shall retain and make available on request to the constructor, inspector or other person involved in the inspections of, tests of, repairs to, modifications to and maintenance performed on the crane or similar hoisting device copies of the log book and all written records for the crane or similar hoisting device referred to in subsection (1).

ss.(4) - New requirement is added for the crane owner to provide, upon request, copies of all written records related to the tests, inspections, repairs, modifications and maintenance performed on a crane to a Ministry inspector or other person involved in any of the above listed activities e.g. professional engineer inspecting the crane, mechanic/technician servicing the crane. Currently, the crane owner only has to provide the information to the constructor on a project. Professional engineers would need to refer to these records in order to comply with engineers’ expanded inspection requirements for tower cranes proposed in sections 158, 159, and 159.1.

153. (1) No worker shall use as a workplace a platform, bucket, basket, load, hook, sling or similar device that is capable of moving and is supported by a cable attached to the boom of a crane or similar hoisting device, except in accordance with this section.

(2) A crane may be used to raise, support or lower a worker only if,

(a) conventional access equipment cannot be used;

(b) the platform that the worker is on,

(i) is designed by a professional engineer in accordance with good engineering practice,

(ii) is constructed in accordance with the design drawings,

(iii) is equipped with more than one means of suspension or support,

(iv) is equipped with anchor points for the attachment of

153. (1) Subject to ss. 153.1 , no worker shall use as a workplace a platform, bucket, basket, load, hook, sling or similar device that is capable of moving and is supported by a cable attached to the boom of a crane or similar hoisting device, except in accordance with this section.

(2) A crane may be used to raise, support or lower a worker only if,

(a) UNCHANGED;

(b) UNCHANGED EXCEPT WHERE NOTED BELOW

(iii) is equipped with more than one means of suspension or support, or is attached to the load block of the crane by a secondary means of suspension,

Although section 153 applies generally to any crane and not just to tower cranes, the Tower Crane Regulation Review Working Group would like to recommend that industry consider this proposed requirement for all cranes.

ss.153(2)(b)(iii) – The revision is proposed by the Ministry, and is meant to clarify the current requirement, provide more compliance flexibility and codify in Regulation a common industry practice used to comply with the requirement.

(v) is equipped with a guardrail in accordance with section 26.3,

(vi) is suspended from, or supported by, a direct attachment to the boom of the crane,

(vii) is designed, constructed and maintained so that the failure of one means of support or suspension will not cause the collapse of all or part of the platform, and

(viii) has its maximum rated load capacity legibly and permanently marked in a conspicuous place on it; and

(c) the crane,

(i) is equipped with fail-safe mechanisms that will prevent the boom and the suspended platform from free falling in the event of a power source or system failure or the inadvertent release of any operating controls,

(ii) is not used to hoist material while the platform is being used to support a worker,

(iii) is not loaded in excess of 25 per cent of its maximum rated load,

(iv) has a revised load rating chart prepared by a professional engineer in accordance with good engineering practice and affixed in a conspicuous place on the crane,

(v) has, on its hoist line, hooks equipped with self-closing safety catches at the point where the platform is suspended, and

(vi) is suspended from the boom or supported by a direct attachment to the boom of the crane,

(iv) has a revised load rating chart

prepared by a professional engineer in accordance with good engineering practice taking into consideration the load restriction in paragraph (iii), and

that is affixed in a conspicuous place on the crane made available to the crane operator prior to the commencement of the hoisting operation,

ss.153(2)(b)(vi) - The minor revision is proposed by the Ministry, and is meant to clarify the current requirement and does not change the current intent of the requirement.

Paragraph (2)(c)(iv) - The minor revisions are proposed by the Ministry, and are meant to clarify the current requirement and do not change the current intent of the requirement A revised load rating chart must be specifically prepared for the hoisting of workers on a platform, incorporating the provision for the crane not to be loaded in excess of 25% of its maximum rated load, thereby unambiguously providing the necessary information to an operator to hoist workers safely. Crane operators would have to be informed about and would have to use the revised load rating chart whenever hoisting workers.

by the crane manufacturer.

(3) Any modifications or repairs to the boom of the crane shall be made in accordance with the instructions of the crane manufacturer or a professional engineer.

(4) Every worker on the platform shall wear a full body harness connected independently to anchor points on the platform and used in conjunction with a lanyard fitted with a shock absorber.

(5) The design drawings of the platform shall,

(a) set out the size and specifications of all components of the platform, including the type and grade of materials used for it;

(b) state the maximum live load of the platform;

(c) specify the model and type of crane to be used in conjunction with the platform; and

(d) include a statement that, in the opinion of the professional engineer who designed the platform, the design meets the requirements of clauses (a), (b) and (c).

(e) Revoked.

(6) Before the platform is used, a competent worker shall inspect it and verify in writing that it has been constructed in accordance with the design drawings.

(7) No person shall use the platform until the verification required under subsection (6) is given.

(8) A professional engineer or a competent worker designated by the professional engineer shall inspect the crane to ensure its structural integrity using non-destructive testing methods approved by the Canadian General Standards Board before the crane is used to lift persons and then at least once every 12 months after that.

(8) (a) A professional engineer or a competent worker designated by the professional engineer shall inspect the crane, except a tower crane, to ensure its structural integrity using non-destructive testing methods approved by the Canadian General Standards Board before the crane is used to lift persons and then at least once every 12 months after that;

(b) (i) (NEW) The inspection of structural components shall include methods of non-destructive testing recognized by the

ss.153(8) – The current wording in the Regulation incorrectly refers to the Canadian General Standards Board (CGSB) i.e. the CGSB does not approve any methods of non-destructive testing (NDT) – rather, it specifies the qualifications and certification of persons involved in NDT. The changes are proposed by the Ministry to correct this historical drafting error and do not change the existing intent or implementation of the requirement.

May 15, 2013


(9) A competent worker shall visually inspect the crane’s structural elements and the rigging equipment for defects before each use of the crane.

(10) The employer shall ensure that an adequate means of communication between the worker on the platform and the crane operator is established, maintained and used.

(11) Before beginning any hoisting operation under this section, the constructor shall notify by telephone an inspector in the office of the Ministry of Labour nearest to the project.

(12) The employer shall ensure that every worker involved with the hoisting operation receives adequate instructions about the requirements, restrictions and hazards associated with the hoisting operation.

(13) The employer shall develop adequate emergency rescue procedures and communicate these in writing to all workers involved with the hoisting operation.

(14) The constructor shall keep all design drawings, test reports, written statements and certification documents required under this section with the crane at all times during the hoisting operation.

(15) On request, the constructor shall provide an inspector with copies of any document described in subsection (14).

CAN/CGSB 48.9712-2006, Non-destructive Testing – Qualification and Certification of Personnel standard; and

(ii) (NEW) the non-destructive testing, and interpretation and evaluation of testing results, shall be conducted by a person certified in accordance with CAN/CGSB 48.9712-2006, Non-destructive Testing – Qualification and Certification of Personnel standard.

(8.1) NEW(8.1) (a) If the crane is a tower crane, a professional engineer shall inspect the structural, electrical, mechanical and hydraulic components and systems of the tower crane and shall test the crane’s control systems in accordance with the Practice Standard for Tower Crane Review developed by the Professional Engineers of Ontario.

(b) (i) The inspection of structural components shall include methods of non-destructive testing recognized by the CAN/CGSB 48.9712-2006, Non-destructive Testing – Qualification and Certification of Personnel Standard; and

(ii) the non-destructive testing, and interpretation and evaluation of testing results, shall be conducted by a person certified in accordance with CAN/CGSB 48.9712-2006, Non-destructive Testing – Qualification and Certification of Personnel standard.

Ss.(9) – (15) REMAIN UNCHANGED

NEW Ss.153(8.1) – If a tower crane is to be used to hoist a worker on a man basket or platform, an engineer must inspect more than just the structural components of the crane prior to the crane hoisting a worker i.e. the engineer must inspect the same items as noted in revised s.159 in accordance with the Practice Standard for Tower Crane Review developed by the Professional Engineers of Ontario (PEO) in consultation with the Tower Crane Regulation Review Working Group rather than “good engineering practice”. The Practice Standard is meant to guide professional engineers in their inspections of tower cranes (see sections 158 and 159 for fully explanation). A tower crane that complies with the proposed s.158 and s.159 (inspected by an engineer before and after its erection and at least every 12 months after that) would be considered in compliance with the inspection requirement in ss.153(8.1).

153.1 (NEW) Where a tower crane is used to move a worker or workers in an emergency operation, the following requirements shall be met:

(a) the emergency procedures required under s.17 involving a tower crane shall be approved by a professional engineer prior to the tower crane being put into service on a project;

The new section 153.1 sets out the requirements when a tower crane is to be part of a constructor’s emergency procedures for a project (as required in section 17) and is intended to be used to hoist workers in some kind of platform, basket, stretcher or rescue device in the event of emergencies. The proposed requirements in ss.(d)(e)(f)(h)(i) mirror similar current requirements in ss.153(9) to (15) ss.(g) has a new inspection requirement. However, the

11

May 15, 2013


(b) the platform, basket, stretcher or other rescue device shall:

(i) comply with ss.153(2)(b) and (5); OR(ii) if it is not practicable to comply with ss.153(2)(b),

1. be designed and approved by a professional engineer to be adequate to move a person or persons in a safe manner;

2. have design drawings in accordance with ss.153(5);

3. be suspended from, or supported by the boom of the crane; and

4. in addition to item 3 above, be attached to the load block of the crane by a secondary means of suspension;

(c) the tower crane shall comply with ss.153(2)(c);

(d) the employer shall develop adequate emergency rescue procedures and communicate these in writing to all workers to be involved in an emergency hoisting operation;

(e) the employer shall ensure that every worker involved in the emergency hoisting operation receives adequate instructions about the requirements, restrictions and hazards associated with the operation;

(f) the employer shall ensure that an adequate means of communication between the worker or workers on the platform, basket, stretcher or other rescue device and the tower crane operator is established, maintained and used during an emergency hoisting operation;

(g) the platform, basket, stretcher or other rescue device shall be inspected by a competent person at least once a week or more frequently as determined by the constructor or by the supervisor appointed by the constructor to ensure the platform, basket, stretcher or other rescue device is maintained in good condition and is ready for immediate use during an emergency;

(h) the constructor shall keep all design drawings for the platform, basket, stretcher or other rescue device, and the written emergency rescue procedures with the crane at all times during

constructor would NOT have to notify the Ministry prior to an emergency hoisting operation (as is currently required for non-emergency hoisting operations under ss.153(11).

Although the new section as currently drafted would apply only to tower cranes, the Tower Crane Regulation Review Working Group recommends that it apply to any crane that is to be used to hoist workers in the event of emergencies.

an emergency hoisting operation; and

(i) on request, the constructor shall provide an inspector with copies of design drawings and emergency rescue procedures described in paragraph (h).

154. (1) A crane or similar hoisting device shall be set up, assembled, extended and dismantled only by a competent worker acting in accordance with the written instructions of the manufacturer and in such a manner as to not endanger any person or property.

(2) No crane or similar hoisting device shall include sections that are not designed for it or that are damaged.

(3) No crane or similar hoisting device shall include nuts, bolts, pins or fastenings that are not the size and quality specified by the manufacturer.

154. (1) A crane or similar hoisting device shall be set up, assembled, extended climbed and dismantled only by a competent worker acting in accordance with the written instructions of the manufacturer and in such a manner as to not endanger any person or property.

(2) No crane or similar hoisting device shall include sections that are not designed for it or that are damaged.

(3) No crane or similar hoisting device shall include nuts, bolts, pins or fastenings that are not the size and quality specified by the manufacturer.

(4) NEW – Every portable or removable counterweight, test block and ballast used on a tower crane must be accurately weighed and its weight must be clearly and durably marked on the counterweight, test block and ballast.

The term “extended” is being replaced with “climbed”. A new definition of “climbing” is also being added to avoid confusion regarding the different types of “climbing” that may be performed on tower cranes e.g. “extending” a tower crane has traditionally meant only “top climbing” of a tower crane.

A new ss.(4) is being added to specifically address a common safety concern related to the use of all cranes. Although the proposed requirement would apply only to tower cranes, the Tower Crane Regulation Review Working Group recommends that it apply to any crane.

155. Unless otherwise specified by its manufacturer, a crane or similar hoisting device,

(a) shall be equipped with a device to indicate whether its turntable is level; and

(b) shall be operated with its turntable level.

155. UNCHANGED

156. An outrigger or stabilizing device used on a crane or similar hoisting device,

(a) shall be extended to meet load capacity chart requirements; and

(b) shall rest on blocking able to support the crane or similar hoisting device and its maximum load without failure or without deformation or settlement which affects its stability.

156. An outrigger or stabilizing device used on a crane or similar hoisting device,

(a) shall be extended to meet load capacity rating chart requirements; and

(b) shall rest on blocking able to support the crane or similar hoisting device and its maximum load without failure or without deformation or settlement which affects its stability.

The term “load rating chart” rather than “load capacity chart” is to be used throughout the Regulation to ensure consistency with CSA Z248-04, Code for Tower Cranes which uses the term “load rating chart”.

TOWER CRANES

156.1 NEW – NOTIFICATION

(1) The constructor shall complete an approved notification form and file it at the Ministry office located nearest to the project:

(a) At least seven (7) days prior to the tower crane, excluding any self-erecting tower crane, being placed into service on the project; and

(b) At least seven (7) days prior to the tower crane, excluding any self-erecting tower crane, being dismantled.

(2) The notification shall specify the:(a) the address of the project at which the tower crane is to be

operated/used;(b) name and address of the tower crane owner/supplier

(lessor);(c) make, model and serial number of the tower crane to be

operated/used; and,(d) date of erection and dismantling of the tower crane.

(3) The constructor shall keep the completed notification form posted in a conspicuous place at the project or available at the project for review by an inspector until the crane is dismantled.

This new requirement is being added at the Ministry of Labour’s direction. To facilitate compliance, the Ministry would develop a notification form (paper and electronic) that a constructor would be able to mail (by conventional or electronic means), fax or deliver in person to the ministry office located nearest to the project.

May 15, 2013


156.2 NEW – DESIGN

After the amendments come into effect (DATE to be specified),

(1) a tower crane that is being put into service in Ontario for the first time,

(a) shall be designed and manufactured in accordance with the European standard EN 14439:2006 or EN 14439:2009, Cranes – Safety – Tower Cranes;

(b) shall meet the requirements in the document, Electrical Specification for Tower Cranes, ESA SPEC-00X-13, published by the Electrical Safety Authority; and,

(c) shall have control equipment incorporating solid state devices, a programmable logic controller and/or software systems in operating and control circuit, designed and installed to meet circuit performance classification that is control reliable meeting category 3 or better in accordance with,(i) ISO 13489-1, Safety of Machinery – safety related parts for control systems, or(ii) EN 954-1:1996, Safety of machinery – Safety-related part of control systems – Part 1: General principles for design.

(2) After a SPECIFIED DATE, a tower crane, other than one described in ss.(1), that is erected on a project,

(a) shall be designed and manufactured in accordance with CSA-Z248-04; and,

(b) shall comply with the requirements in ss.(1)(b) and (c).

New design specifications for tower cranes are being added, supported by a revised and more rigorous inspection regime and new verification process by engineers, to ensure tower cranes will not endanger workers. As internationally manufactured tower cranes are routinely designed to this European standard, compliance with this new requirement is not expected to be onerous with respect to cranes imported into Ontario after the new requirements come into effect (if approved).

ss.(2) - There would be an implementation period for owners of cranes already in Ontario when the new proposed requirements come into effect, to give owners time to make necessary modifications to their cranes so they can comply with the design requirements of CSA Z248-04, Code for Tower Cranes, as well as the ESA’s Electrical Specification for Tower Cranes and the control equipment requirements in ss.156.(1)(b) and (c).

QUESTION TO INDUSTRY: How long should this implementation period be e.g. 2 years? Industry is being asked to provide feedback to the Provincial Labour-Management Health and Safety Committee on how much time

16

May 15, 2013


would be reasonable to give to crane owners to enable them to bring their existing cranes into compliance with the new design requirements.

Tower cranes in service on a project when the new proposed requirements come into effect, would be allowed to continue to operate. However, once their work is completed and they are dismantled and removed from a project, they would also have to be reviewed and brought into compliance with the new design requirements.

QUESTION TO INDUSTRY: The regulation of tower cranes in Europe has historically required more rigorous inspections of older cranes. Anecdotal evidence indicates that crane owners, rather than undergoing the expense of these rigorous inspections, often sell their cranes instead which are subsequently sometimes brought to Ontario. The Ministry’s past tower crane blitzes indicated that many older cranes were not being properly maintained and as a result, exhibited defects. Industry is being canvassed for feedback whether there is a need for more thorough inspections for older tower cranes as well as after a tower crane undergoes a major alteration.

1. Should tower cranes be required to undergo a more thorough inspection than the annual inspection regime specified in the Practice Standard for Tower Crane Review developed by the Professional Engineers of Ontario after they reach a certain age and/or after a major alteration and/or after a serious defect has been identified?

1. What should be included in this more thorough inspection?

2. What should be the minimum age of a crane before it would be required to undergo a more thorough inspection e.g. 10 yrs? 15 yrs?

3. How often should an older crane be required to undergo a more thorough inspection e.g. every 3 yrs? 5 yrs?

17

TOWER CRANES

157. (1) No tower crane shall be erected at a project except in accordance with this section.

(2) The foundations supporting a tower crane shall be designed by a professional engineer in accordance with the crane manufacturer’s specifications and shall be constructed in accordance with the design.

(3) The shoring and bracing that support a tower crane or tie it in place shall be designed by a professional engineer in accordance with the crane manufacturer’s specifications and shall be installed in accordance with the design.

(4) The structural engineer responsible for the structural integrity of the building or structure shall review the design drawings for the foundation, shoring and bracing for a tower crane before the crane is erected at a project to ensure the structural integrity of the building or structure.

(5) The structural engineer who reviews the design drawings shall sign the drawings upon approving them.

(6) The constructor shall keep at the project while a tower crane is erected a copy of the signed design drawings for its foundation, shoring and bracing and any written opinion about the drawings by a structural engineer.

157. (1) A tower crane, other than a rail-mounted tower crane, shall be erected at a project in accordance with this section.

(2) The foundation or work surface supporting a tower crane shall be designed by a professional engineer in accordance with the crane manufacturer’s specifications and shall be constructed and installed in accordance with the design drawings.

(3) The shoring and bracing that support a tower crane or tie it in place,

(a) shall be designed by a professional engineer in accordance with the crane manufacturer’s specifications and, if no such specifications exist, in accordance with good engineering practice, and

(b) shall be constructed, installed and dismantled in accordance with the design drawings.

(4) The structural professional engineer responsible for the structural integrity of the building or structure shall review the design drawings for the foundation, shoring and bracing for a tower crane before the crane is erected at a project to ensure the structural integrity of the building or structure.

(5) The structural professional engineer who reviews the design drawings referred to in subsection (4) shall sign the drawings upon approving them.

(6) The constructor shall keep at the project while a tower crane is erected a copy of the signed design drawings for its foundation, shoring and bracing and any written opinion about the design drawings by a structural professional engineer.

ss.(1) – Rail-mounted tower cranes are addressed under s.165.

ss.(2) - The deletion of “in accordance with the crane manufacturer’s specifications” in ss.(2) is necessary since a tower crane manufacturer’s specifications and instructions do not address the design and inspection of a crane’s foundation, shoring or bracing.

ss.(2) – Since many self-erecting tower cranes are not erected on foundations but on other solid material or bare ground, the term “work surface” was added to ensure that whatever surface supports a self-erecting tower crane, it is assessed by an engineer and “designed” to support the crane in a safe manner.

19

May 15, 2013


158. (1) Before a tower crane is erected at a project, a professional engineer or a competent worker designated by a professional engineer shall inspect its structural elements and components using methods of non-destructive testing approved by the Canadian General Standards Board to determine their structural integrity.

(2) The professional engineer conducting an inspection or under whose direction an inspection is done shall prepare a written report of the test results.

158. (1) Before a tower crane, except a self-erecting tower crane, is erected at a project, and before a self-erecting tower crane is erected for the first time,

NEW(a) a professional engineer or a competent worker designated by a

professional engineer shall inspect its structural, electrical, mechanical and hydraulic components and systems, and its control systems, in accordance with the Practice Standard for Tower Crane Review developed by the Professional Engineers of Ontario, and identify any defects that may affect worker health and safety,

(b) the inspection of structural components in clause (a) shall include methods of non-destructive testing recognized by the CAN/CGSB 48.9712-2006, Non-destructive Testing – Qualification and Certification of Personnel standard; and

(c) the non-destructive testing, and interpretation and evaluation of testing results, shall be conducted by a person certified in accordance with CAN/CGSB 48.9712-2006, Non-destructive Testing – Qualification and Certification of Personnel standard. .

(2) The professional engineer conducting an inspection or under whose direction an inspection is done shall prepare a written report of the inspection and test results including confirmation that all components are in adequate condition.

(3) NEW – No tower crane shall be used until:

(a) any defects identified in the inspection in subsection (1) that may affect worker health and safety are corrected or repaired in accordance with the instructions of the tower crane manufacturer or a professional engineer,

(b) the tower crane has been inspected by a professional engineer to confirm that the defects are corrected or repaired and that the repaired components are in adequate condition; and

A stronger inspection regime is being proposed for tower cranes. Ministry of Labour’s past enforcement experience indicated defects and unsafe conditions in not only structural elements of tower cranes but also in their electrical, mechanical (e.g. hoists) and hydraulic components and systems as well as control systems. For this reason, the current inspection requirement is being expanded beyond structural elements of tower cranes.

In addition, Ministry’s past tower crane enforcement campaigns indicated tower cranes were being inspected by professional engineers, as required by section 158, in an inconsistent manner and that engineers’ inspection reports varied greatly. To address this inconsistency, the Professional Engineers of Ontario (PEO) developed a Practice Standard for Tower Crane Review, in consultation with the Tower Crane Regulation Review Working Group, to guide professional engineers in their inspections of tower cranes (see attached document). The attached Practice Standard is still a draft but very close to being completed. The finalized Practice Standard is not expected to be much different from the attached draft version. Once finalized by the PEO, the Practice Standard is expected to be made into a regulation under the Professional Engineers Act which would replace the current reference to the Practice Standard in the final proposed amendments to the Construction Regulation. Professional engineers would then be required to follow the new regulation under the Professional Engineers Act when inspecting tower cranes in compliance with the Construction Regulation.

The phrase, “or a competent worker designated by a professional engineer” is being removed at the request of the PEO as it is not consistent with the Professional Engineers Act. The PEO is expected to clarify shortly (and before the proposed amendments are finalized by the Ministry) whether an additional phrase should be added consistent with the Professional Engineers Act which currently allows a professional engineer to delegate duties/functions to a designated person who is under the engineer’s direct supervision.

20

May 15, 2013


(3) The constructor shall keep the report at the project while the crane is erected.

(c) the professional engineer in clause (b) has prepared a written report of the corrections and repairs and results of the inspection in clause (b).

(4) The constructor shall keep all reports required under this section at the project while the crane is erected at the projected and shall make them available to an inspector upon request.

159. (1) A professional engineer or a competent worker designated by a professional engineer shall visually inspect for defects the structural elements and components of a tower crane,

(a) after the crane is erected and before it is used; and

(b) after the inspection under clause (a), at intervals not greater than twelve months.

159. (1) Except for a self-erecting tower crane, a professional engineer or a competent worker designated by a professional engineer shall visually inspect the structural, electrical, mechanical and hydraulic components and systems of a tower crane, and shall test the control systems of a tower crane, in accordance with the Practice Standard for Tower Crane Review developed by the Professional Engineers of Ontario, and identify any defects,

(a) after the crane is erected and before it is used; and

(b) after the inspection under clause (a), at intervals not greater than twelve months.

(1.1) (NEW) :(a) A professional engineer shall inspect the structural, electrical,

mechanical and hydraulic components and systems of a self-erecting tower crane, and shall test the control systems of a self-erecting tower crane, in accordance with the Practice Standard for Tower Crane Review developed by the Professional Engineers of Ontario, and identify any defects,

(i) every 6 months while the crane is in use; or

(ii) after every 12 erections of the crane,

whichever comes first.

See explanation for proposed changes in section 158.

NEW subsection (1.1) – Because self-erecting tower cranes are often erected and dismantled on a frequent basis for use at different projects e.g. sometimes daily, they are more prone to being damaged than regular tower cranes and should be inspected periodically when they are in service to ensure they are maintained good condition.

21

May 15, 2013


(2) No tower crane shall be used until any defects found during an inspection are repaired in accordance with the instructions of the crane’s manufacturer or a professional engineer.

(3) A professional engineer or a competent worker designated by a professional engineer shall inspect a tower crane that has been repaired to ensure that the defects are corrected.

(3) NEW – No tower crane shall be used until:

(a) any defects identified in the inspection in subsection (1) that may affect worker health and safety are corrected or repaired in accordance with the instructions of the tower crane manufacturer or a professional engineer;

(b) the tower crane has been inspected by a professional engineer or a competent worker designated by a professional engineer to confirm that the defects are corrected or repaired and that the repaired components are in adequate condition; and

NEW subsection (1.2) – Is consistent with CSA Z248-04, Code for Tower Cranes, clause 5.9.8.9.

22

May 15, 2013


(4) The professional engineer conducting an inspection or under whose direction the inspection is done shall prepare a written report of the test results.

(5) The constructor shall keep the report at a project while the crane is erected.

(c) the professional engineer in clause (b) has prepared a written report of the corrections and repairs and results of the inspection in clause (b).

(4) The constructor shall keep all reports required under this section at a project while the crane is erected at the project and shall make them available to an inspector upon request.

159.1 NEW –

(1)(a)(i) The foundation supporting a tower crane shall be inspected by a professional engineer before the concrete is poured, and

(ii) the work surface, other than a poured concrete foundation, supporting a tower crane shall be inspected by a professional engineer before the crane is erected,

to confirm that the foundation or work surface complies with the foundation design drawings or the design drawings subject to any deviations as approved by a professional engineer in subsection 157(2).

(b) A written report of the inspection prepared by the professional engineer in clause (a) shall be kept at the project while the tower crane is at the project and shall be made available to an inspector upon request.

(c) The tower crane shall not be erected until the concrete foundation reaches the strength specified in the foundation design drawings.

(2)(a) The shoring and bracing that support a tower crane or tie it in place shall be inspected by a professional engineer after the shoring and bracing or the tie-ins have been installed and before the crane is put into service for the first time on the project.

23

May 15, 2013


(b) The professional engineer shall prepare a written report of the inspection in clause (a) including confirmation that the shoring and bracing or the tie-ins have been installed in accordance with the design drawings or the design drawings subject to any deviations approved by a professional engineer in ss.157(3) and the building or structure has reached sufficient strength to resist the crane reactions.

(c) The written report prepared in clause (b) shall indicate the circumstances that would require additional inspections of the shoring and bracing or tie-ins by a professional engineer after the initial inspection in clause (a).

(d) A written report of the inspections in clauses (a) and (c) shall be kept at the project while the tower crane is at the project and shall be made available to an inspector upon request.

(ii) after the inspection in paragraph (i), at intervals not greater than 12 months.

(3)(b) The professional engineer conducting an inspection shall prepare a written report of the inspection in clause (a) and its test results including confirmation that all components are in adequate condition.

ss.(2)(c) NEW – A new requirement is added that is cross referenced in ss.(5) regarding the inspection of shoring, bracing and tie-ins before and after climbing operations. For routine kinds of climbing operations, a competent worker can perform the inspection. However, if the climbing operation is unusual/ complicated, it may be appropriate for an engineer to perform the post-climbing inspection to ensure the shoring, bracing and tie-ins have been installed correctly and in accordance with the design drawings. It should be the responsibility of the engineer to determine when an engineer rather than a competent worker should perform this inspection and to specifically note it in the report.

24

May 15, 2013


(4)(a) Each major component used for shoring the tower crane shall be marked by a conspicuous label stating that the component shall not be removed or repositioned unless authorized by the professional engineer in ss.(2)(a).

(b) The label in clause (a) shall be in place on the component while the component is being used at the project.

(5)(a) After the initial inspection by a professional engineer in ss.(2)(a), the shoring and bracing components and tie-ins installed for the climbing operation shall be inspected:

(i) by a competent worker before and after each climbing operation of the crane unless otherwise specified by the professional engineer in the written report under ss.(2)(c), to ensure the shoring and bracing components and tie-ins have been installed in accordance with the design drawings prepared in ss.157(3), and

NEW ss.161(3)(b) – CSA Z248-04 requires a minimum factor of safety of 3:1 on yield for lifting hardware. To avoid confusion and to reinforce and maintain consistency with existing rigging requirements in the Construction Regulation, ss. 161(3)(b) is being added which mirrors the existing requirement in ss.172(1)(d) and is equivalent to a factor of safety of 3:1 on yield that is referenced in the CSA standard.

27

May 15, 2013


(8) NEW While a tower crane is in service at the project, it shall be inspected,

(a) daily by the crane operator as follows:

(i) ensure all wedges in slab openings are in place and are tight,

(2.1)(NEW) A written record required under subsection (1) shall be included in the permanent record required under ss. 152(1) and in the log book required under section 152 for a tower crane.

(2) UNCHANGED;

The NEW clause (f) in ss. 168(1) means the entire wire rope has to be replaced if it has come into contact with electricity at any voltage. Industry experience indicates that electrical current can travel throughout the length of the wire rope and cause internal damage that is not visible upon inspection but can cause the rope to fail.

ss.(1.1) NEW - A new requirement for a written record in subsection 1.1 is being added consistent with CSA standard Z248-04, Code for Tower Cranes, Section 4.11.3. Such a written record would help ensure the appropriate wire rope is used and that it is used properly on a tower crane. The term “written record” is being used rather than the term “test certificate” that is used in the CSA standard as the latter term may infer some kind of “testing” has to be done on the wire rope to complete the written record.

(5) Rotation-resistant wire rope shall not be used where an inner wire or strand for a cable is damaged or broken.

re: the use of rotation-resistant wire rope used on tower cranes, consistent with CSA standard Z248-04, Code for Tower Cranes, Section 4.11.

Subsection 168(5) is deleted since a damaged inner wire or strand of a cable cannot be seen by a visual inspection.

168.1 (NEW)Swivels shall not be used on boom hoist cable on a tower crane unless they are allowed,

(a) by the tower crane manufacturer and wire rope manufacturer, or

(b) if the tower crane manufacturer is no longer in business, by a professional engineer and the wire rope manufacturer.

The addition of a new requirement regarding swivels is based on industry experience and the CSA standard Z248-04, Code for Tower Cranes. However, unlike the CSA standard clause 4.11.2(h), the section requires that the use of swivels must be allowed by both crane AND wire rope manufacturers. If either the crane or wire rope manufacturer recommends that swivels not be used with its respective product, then swivels must not be used on boom hoist cable. The CSA standard allows the use of swivels if either the crane OR rope manufacturer permits swivels to be used.

169. A cable used by a crane or similar hoisting device shall be capable of supporting at least,

(a) three and one-half times the maximum load to which it is likely to be subjected if it is used on a device other than a tower crane and it winds on a drum or passes over a sheave;

(b) five times the maximum load to which it is likely to be subjected if it is used on a tower crane and it winds on a drum or passes over a sheave;

(c) three times the maximum load to which it is likely to be subjected if it is a pendant or is not subject to

170. (1) All cable used by a crane or similar hoisting device shall be visually inspected by a competent worker at least once a week when the crane or similar hoisting device is being used.

(2) The worker performing an inspection shall record the condition of the rope or cable inspected in the log book for the crane or similar hoisting device.

170. (1) Except for a tower crane and subject to ss.161(8), all cable used by a crane or similar hoisting device shall be visually inspected by a competent worker as frequently as recommended by the cable manufacturer and in any case, at least once a week when the crane or similar hoisting device is in service.

(2) The worker performing an inspection shall record the condition of the rope or cable inspected in the log book for the crane or similar hoisting device.

The changes to ss.170(1) clarify that cable on tower cranes has a more detailed inspection requirement in ss.161(8) and cable on all other cranes must be visually inspected at a minimum of once a week or more frequently than once a week if so recommended by the cable manufacturer.

171. (1) A cable used by a crane or similar hoisting device shall be securely attached,

(a) by binding and fastening the cable around an oval thimble in a way that is strong enough to prevent the cable thimble from separating; or
