EQUIPMENT SAFEGUARDING
GOLDEN RULES FOR EQUIPMENT SAFEGUARDING
Good communication must always convey awareness to all the team
members
EQUIPMENT SAFEGUARDINGGOLDEN RULES FOR EQUIPMENT
SAFEGUARDING
Remember no work is so Important and Urgent that it should be conducted in an unsafe manner.
EQUIPMENT SAFEGUARDINGSection 1
MHSA Requirements
Regulation 8.8(1)
The employer must take reasonable and practicable measures to prevent persons from being injured as a result of them, the cloths being worn by employees or any equipment being held by them coming into contact with or being drawn into any moving part of any machine.
EQUIPMENT SAFEGUARDINGCHAPTER 20
MINERALS ACT REGULATIONS
Regulation 20.5
All exposed machinery which, when in motion, may be dangerous to any person shall be securely fenced off. Efficient guards shall be provided to such parts of any machinery as may be a source of danger to any.
EQUIPMENT SAFEGUARDING
Act 15 of the OHSA.
DUTY NOT TO INTERFERE WITH, DAMAGE OR MISUSE THINGS
No person shall intentionally or recklessly interfere with, damage or misuse any thing which is provided in the interest of health or safety.
EQUIPMENT SAFEGUARDINGOHSA.
GENERAL MACHINERY REGULATIONSSafeguarding of machinery(a) Every employer or user of machinery
shall-ensure that all machinery used by him, is suitable for the purpose for which it is used, and that it is installed, operated and maintained in such a manner as to prevent the exposure of persons to hazardous or potentially hazardous conditions or circumstances
EQUIPMENT SAFEGUARDINGOHSA.
GENERAL MACHINERY REGULATIONSSafeguarding of machinery(b) In particular cause every exposed and
dangerous part of machinery which is within the normal reach of persons to be effectively safeguarded by means of insulators, fencing, screening or guarding, except where an inspection has granted written permission for the omission of such safeguarding
EQUIPMENT SAFEGUARDINGSection 2
New Plant and Equipment.
Anglo Platinum Smelters have recognized the fact that exposed moving parts of machinery must be kept to a minimum.
THEREFORE
EQUIPMENT SAFEGUARDING
Suppliers of Machinery were requested to consider every possible means whereby the need for a guard to prevent contact with exposed moving machinery can be eliminated wherever possible.
This can only be achieved by eliminating the moving components that require guarding.
EQUIPMENT SAFEGUARDING
EQUIPMENT SAFEGUARDINGSection 2
How can this be achieved?
Examples of how it can be achieved are as follows:
Hydrostatic drive systemsDirect coupling of external casings with
internal drive shaftsMotorized drums Etc.
EQUIPMENT SAFEGUARDING
Continuous Improvement.
Engineering staff must consider the replacement of existing guard arrangements with drive systems with no external moving parts to which people can be exposed.
EQUIPMENT SAFEGUARDINGSection 3
Plant and equipment safeguarding
Anglo Plats Smelters have recognized the fact that guarding moving parts of machinery, is not only a legal requirement, but an essential requirement to comply to our value of:
Preventing injuries byPUTTING SAFETY FIRST!!!
EQUIPMENT SAFEGUARDINGSection 4
Guards Designed and Installed to prevent contact with moving parts
Guards are often designed and installed around the moving parts of machinery to prevent contact with the moving parts and subsequent injury.
THEREFORE
EQUIPMENT SAFEGUARDINGSection 4
It is essential that any guard fitted to prevent contact with moving machinery parts must prevent contact by reaching:
• Upwards towards the moving part• Under the guard• Over the guard• Into the guard• Around the guard• Through the guard
EQUIPMENT SAFEGUARDING
Examples of unsafe Machine Guards
EQUIPMENT SAFEGUARDING
Section 4
Anglo Plats Smelters have standardized on a simple set of guarding design standards that meets all the recommendations for equipment guarding. These guards are effective and easy to maintain.

EQUIPMENT SAFEGUARDINGSection 5.1
Maintenance of Installed Guarding.
Once equipment guarding has been designed and installed, it obviously has to be well maintained in order to ensure the effectiveness for its purpose.
EQUIPMENT SAFEGUARDINGSection 5.2
Each Smelter operation has a planned maintenance system that will call for the periodic inspection of machine guarding.
Damaged guards must be repaired immediately when detected.
EQUIPMENT SAFEGUARDINGSection 5.3
Managers and Supervisors must carry out audits and over inspections on maintenance work carried out in order to ensure the ongoing effectiveness of machinery guards.
EQUIPMENT SAFEGUARDINGSection 5.4
REMEMBER the following NEVERSwhen doing maintenance on Machine Guarding:
When maintaining a machine guard, always check and make sure that the guard complies with the Smelter Standard for guards (Appendix 1).
EQUIPMENT SAFEGUARDINGSection 5.5
Never remove a guard to do a job without making sure that the moving machinery you areabout to work on has been isolated and locked-out.
EQUIPMENT SAFEGUARDING
Section 5.6
Before removing a guard, always check for stored energy that could cause injury by inadvertently setting machinery parts into motion – all stored energy must also be isolated and locked-out.
EQUIPMENT SAFEGUARDING
Section 5.7
NEVER REMOVE a guard to do a job without replacing the guard after the job has been completed.
EQUIPMENT SAFEGUARDINGSection 5.8
NEVER MODIFY a guard unless the Responsible Engineer has approved the modification aspart of an approved design change.
EQUIPMENT SAFEGUARDINGSection 5.9
NEVER cut away a section of a guardbecause it makes your job easier to perform.
Do not cut a hole into a guard to quickly check “V” belt tension between pulleys (or for any other seemingly convenient purpose e.g. Lubricating) because this causes the guard to be ineffective in its purpose – always remove the guard and replace it in an effective condition after checking the “V” belt tension or when equipment was lubricated. Etc.

SECTION 6
Interlocking Systems to Prevent Contact with Moving Machinery Parts
EQUIPMENT SAFEGUARDINGChapter 21
Minerals Act Regulations
Regulation 21.4
No person shall interfere with or render ineffective any electrical apparatus provided for safety or protection unless it is necessary to do so to perform work associated with such apparatus.
EQUIPMENT SAFEGUARDINGSection 6.1
Certain machines are designed, assembled and commissioned to run inside an enclosure that places the moving parts of the machine in a position where contact with the moving parts cannot be made because of the protection offered by the enclosure.
i.e. Screw Compressors, Automated Metallurgical Dewatering Filter Press (Larox) systems etc.
EQUIPMENT SAFEGUARDINGSection 6.2
Interlocking 2
The above systems are permitted but the moment a protective cover is removed or gate is opened to the extent that access to moving parts becomes possible, a limit switch or other sensing device must cause the machine to trip out and come to a stop.
EQUIPMENT SAFEGUARDINGSection 6.3
Interlocking 3The design of such a machine must ensure that all moving parts are stationary before any person can come into contact with such parts and cause injury to himself/herself.
EQUIPMENT SAFEGUARDINGSection 6.4
Interlocking 4
The reliability of the aforementioned machine tripping devises must be maintained and such devices may not be bridged out or made inoperable under any circumstances.
EQUIPMENT SAFEGUARDINGSection 7: Temporary removal of guarding.
Where the temporary removal of guarding or other safeguard/s becomes necessary on operating plant and equipment, for the purpose of maintenance, inspection, fault finding, testing, commissioning or for any other reason,
EQUIPMENT SAFEGUARDINGSection 7.2
Temporary removal of guarding 2.
A pre-work HIRA must be carried out for such work.
Written permission must be obtained from the Responsible Engineer.
Guards shall be replaced prior to such plant and equipment being put back into operation again.
EQUIPMENT SAFEGUARDINGREMEMBER 1:
Never work on moving equipment that has not been isolated and locked out!
EQUIPMENT SAFEGUARDINGREMEMBER 2:
A guard must always be replaced before machinery is allowed back into operation.
EQUIPMENT SAFEGUARDINGREMEMBER 3:
A works order must always be generated and a pre-work HIRA must always be carried out for work requiring the removal of a guard – even if this work is part of operational requirements (see Isolation, Lock-Out and Clearance to Work Code – Section 10.6.1).
EQUIPMENT SAFEGUARDINGLock-Out and Clearance to Work
Code – Section 10.6.1).
An approved Works Order (job card) must be generated for all work before any person is assigned responsibility to ensure that the work is carried out.
EQUIPMENT SAFEGUARDINGLock-Out and Clearance to Work
Code – Section 10.6.1).The aforementioned work includes:(i) Maintenance and Repair Work(ii) Installation and commissioning
work(iii) Building and construction work
EQUIPMENT SAFEGUARDINGLock-Out and Clearance to
Work Code – Section 10.6.1).(iv) Any other work for which a routine
operating procedure has not been developed including (but not restricted to) work necessitating the temporaryremoval of guarding, cleaning, washing down, the removal/disposal of spillage, rubble, slurry or residue.
EQUIPMENT SAFEGUARDINGLock-Out and Clearance to Work
Code – Section 10.6.1).
Provided that: all work for which a works order is generated must be considered non-routine work in terms of AFRS requirements for non-routine work.
EQUIPMENT SAFEGUARDINGSection 8.1Access Control
Access Control Requirements where Guarding and Interlock Systems are Insufficient to Protect People.
EQUIPMENT SAFEGUARDINGSection 8.2:
There is so much industrial activity taking place in a Smelter that the need to protect persons from harm by restricting their entry into areas that may be unsafe to them is essential.
The following methods are used to control entry and prevent persons from entering into a place where they may be inadvertently exposed to danger:
EQUIPMENT SAFEGUARDINGSection 8.3
(a) Electronic sensing and recording of entry:
This method is normally applied at the main access points into a Smelter or other area of(i.e. a clock card allowing entry through a turnstile) or other area within a Smelter wherethe number of persons requiring entry at any time necessitates such a method of control.
EQUIPMENT SAFEGUARDINGSection 8: Access Control 4
In such a case, the reason/s for preventing entry would be to filter out and prevent the entry of persons:
Who have not undergone induction and are therefore not aware of site rules and PPE requirements.
Who are not in possession of a mandatory medical certificate of fitness.
Persons who have failed to renew their medical or induction certificates on time.
Persons who are excluded from entry by management.i.e. persons who have been suspended and face disciplinary action etc.
EQUIPMENT SAFEGUARDINGSection 8.5:
By the same token:Persons who are required to be within a Smelter
area at any time, who are aware ofthe rules for entry and comply with such rules are allowed entry.
A record is automatically made of all persons who enter and leave such an area: this capability is very important because it also provides an immediate record of who isinside the operational area at any time.
EQUIPMENT SAFEGUARDINGSection 8.6
Electronic sensing and recording of entry is also used for controlling and restrictingaccess into certain sections of the operation to specified persons.
EQUIPMENT SAFEGUARDING
b) Confined Space or High Risk Location Entry Permit
The Issue of which is dependent on (risk based) requirements for ensuringsafe access to these High Risklocations e.g. for allowing entry into a Confined Space or High Risk location.
EQUIPMENT SAFEGUARDING
This method of Equipment Safe Guarding is used to control entry into areas or locations that are known to have a high risk upon entry and for which a
“CONFINED SPACE OR HIGH RISK LOCATION ENTRY PERMIT IS
REQUIRED”
ISOLATION RECORD
BOOK
EQUIPMENT SAFEGUARDING
Entry into these areas will require the Occupational hygienist or other competent and authorized person to declare the atmosphere and environment therein safe before any person is allowed to enter because:
EQUIPMENT SAFEGUARDING
There may not been sufficient oxygen-Solid or particulate material may fall-It may contain water or slurry-You can fall due to slipperiness and
inadequate support-May contain poisonous fumes or
gasses-There may be explosive or flammable
gasses or substances present-It may be to hot or to cold inside-
EQUIPMENT SAFEGUARDING
There may also be other Hazards inside confined space or High Risk Location therefore the Engineering Foreman/Supervisor in charge is required to facilitate a HIRA before entry is allowed into any Confined or High Risk Location.
EQUIPMENT SAFEGUARDING
There should always be a sign at the entrance to a Confined Space or High Risk Location warning people to this effect.
Confined Space / High Risk Location
EQUIPMENT SAFEGUARDINGNEVER ENTER A CONFINED SPACE OR
HIGH RISK LOCATION UNLESS:The responsible Occupational
Hygienist has declared the atmospheretherein safe for entry.A HIRA has been carried out for the
work inside the Confined Space or High Risk Location.
EQUIPMENT SAFEGUARDINGYou know the precautions to be taken
to protect your safety and the safety of your team members when you enter the location.You have been issued with a Confined
Space or high Risk Location Entry Permit by the Responsible Operator.
EQUIPMENT SAFEGUARDINGSection 8.7
c) Locked gate or door with log book records of entry and purpose of entry:This method is generally used where the frequency of entry is not high enough to justifythe cost of installing and maintaining an Electronic Sensing System for controlling entryinto certain restricted areas. However, the importance of controlling entry and recording such entry still remains.
EQUIPMENT SAFEGUARDINGSection 8.8 A typical example, this type of control is when an electrician
enters a medium voltage electrical distribution substation to carry out medium voltage switching.The electrician will enter the substation through a locked door using a key that only he/she is allowed to posses and records the time of entry and reason for entry into a “substation log book”. After completing the intended work, he/she will record the fact that the intended work is completed, the time that he/she leaves the sub station and makes sure that all substation doors are safely locked to keep persons who are not allowed into the substation out of this potentially dangerous area.
EQUIPMENT SAFEGUARDINGSection 8. 9
Another typical example is when a security guard allows a vehicle into a restricted area by pre-arrangement –the guard allows the vehicle to pass through a set of gates that are normally locked after recording the details of the vehicle and the details of driver.
EQUIPMENT SAFEGUARDINGSection 8. 10
c) Signage and Demarcation:This method generally applies to the necessity to warn, inform and /or remind personswho have already been informed that they are not permitted into certain areas.The aforementioned information is usually provided initially during site induction and orientation.
EQUIPMENT SAFEGUARDINGSection 8: Access Control 11
Typical examples of access control by means of signage and demarcation are as follows:
Specific Workshop Areas: Unauthorized Entry Prohibited
Water Storage Areas: Danger of Drowning –Unauthorized Entry Prohibited
Safe Walkways: Danger – Moving Vehicles –Pedestrians Must Use Safe Walkways.

EQUIPMENT SAFEGUARDINGSection 9.1
Fail-to-Safe Switches for Power Driven Tools.i.e.
• Hand held drilling machines, • Saws, • Lathes, • Drill presses, • Pipe threading machines• etc
EQUIPMENT SAFEGUARDINGSection 9.2 Fail safe Switches
(a) Hand Held Portable Power Driven Tools:All hand held portable power driven tools such as hand held drilling machines, hand held grinders, hand held jig saws etc must stop the moment the user releases thepower supply switch.
EQUIPMENT SAFEGUARDINGSection 9.3 Fail safe Switches
It is not permitted to use a power driven hand tool that has a button or other devise that overrides the “automatic switching off of power” when the power switch of the tool is released.
EQUIPMENT SAFEGUARDINGSection 9.4 Fail safe Switches
(b) Other manually driven power tools that are not hand held such as lathes, pipe threading machines and drill presses must also be fitted with Fail-to-safe power supply switches.
EQUIPMENT SAFEGUARDINGSection 9.5 Fail safe Switches
In the case where the power driven tools are not hand held, a foot operated switch is usually provided so that the moment an authorized user steps away from his / her place of attendance on the operation of the machine, the power supply to the machine is automatically switched off and the machine comes to a stop.
EQUIPMENT SAFEGUARDINGSection 9.5 Fail safe Switches
Note:No manually operated power tools may be used unless such tools are fitted with Fail-to-Safe power supply switches.
