3.5 HAZARD IDENTIFICATION, RISK ASSESSMENT AND CONTROL3 ha-ard identication risk assessment and control process will be carried out by the contractor inconsultation with the principal contractor to determine if persons are at risk. Safe systems of work willthen be put into place to control the risk. The identication of the ha-ards associated with excavationwork, the risk assessment and the risk control measures will be documented. The process of ha-ardidentication, risk assessment and control is made up of the following steps. %dentify the ha-ards0. 3ssess the risk!s" arising from the ha-ards.:. ;se appropriate control measures to eliminate or reduce the risk!s".6. Monitor and review the control measures to ensure continual safety. 3fter identifying the ha-ardsinvolved in carrying out the work the principal contractor in consultation with the contractor willassess the health and safety risks and determine what type of safeguards or systems of work will beimplemented to ensure the health and safety of all persons on site. This will always includeeliminating exposure of persons to the ha-ard.

3. HIERARCHY OF CONTROL MEASURESThe following hierarchy of control measures is listed in terms of levels. Selecting the highest levelpossible to develop each control measure.5evel +liminate the ha-ard

< =or example, choose di$erent +xcavation method.5evel 0 Minimi-e the risk by

< substituting the system of work or plant !with something safer".< modifying the system of work or plant !to make it safer".

< isolating the ha-ard !e.g. introduce a restrictive work area".< introducing engineering control !e.g. dust control".5evel : >ther controls

< adopting administrative controls such as ha-ard warning signs and specic training and workinstructions.< using personal protective e(uipment !e.g. eye, respiratory and hearing protection". The controlmeasures at 5evel !eliminate the ha-ard" give the best results and will be adopted. The measuresat 5evels 0 !minimi-e the risk" and : !other controls" are less e$ective and they re(uire morefre(uent reviews of the ha-ards and systems of work. %n some situations a combination of controlmeasures may need to be used. The control measures recommended by the contractor will beconsidered by the principal contractor as part of the health and safety management plan. 3ny newcontrol measures will be evaluated to ensure that they are e$ective and safe and that new ha-ardsare not created !directly or indirectly" by them.

3.! PREPARATION&hen preparing for the commencement of work the principal contractor and the contractor doing thework will ensure that the workplace is safe based on the health and safety management plan. They

will also check to ensure that all controls identied by the risk assessment have been put in place andthat none ha-ards exist. Preparation will also at least include

!a" an assessment of climatic1environmental conditions.!b" access to and from the workplace.!c" specic instructions for employees.!d" that plant and e(uipment is suitable for the intended use and inspected bay third party beforeuse and is properly maintained.!f" personal protective e(uipment.

!g" that the location of underground, above ground and overhead services are identied and clearlymarked.!h" emergency and rescue procedures in the event of an accident, injury or other emergency,including the means of protect any other persons in the vicinity.

3." EMERGENCY AND RESCUE PROCEDURESThe contractor will ensure that, in the event of an emergency, ade(uate arrangements have beenmade to ensure the safety of workers and other persons on site. The emergency may result from anaccident or injury, landslip or other potentially dangerous occurrence. #atural disaster includingelectrical storms, ?oods, plant or machinery re etc may also present ha-ards to the workingoperations. The contractor will plan for such matters and ensure that appropriate control measuresare in place. The risk assessment will take into account the following factors

!a" nature of ha-ard and possible emergencies/

!b" si-e and location of place of work/!c" number and mobility of persons at the workplace/ and!d" location of nearest emergency services.

)ontrol measures may include!a" development and communication of a warning system.!b" development and communication of

safe and rapid evacuation procedures, including injured persons.!c" having trained personnel to oversee evacuation and rescue procedures until emergency

authorities arrive.!d" appropriate medical treatment and evacuation of injured persons.!e" shutting down of work, including plant and electrical e(uipment.!f" provision of reghting e(uipment at appropriate locations.!g" display of evacuation procedures in appropriate location!s"

4. #ORK SYSTEMS AND CONTROL MEASURESThe principal contractor and contractor have an obligation under *S+ regulations to provide andmaintain a workplace that is safe and without risks to health for their employees in relation to thosematters over which they have control. )ontrol measures to prevent persons being injured duringexcavation work will be provided and maintained as part of a safe system of work. The system of workand control measures selected will be determined by individual job factors identied in theconsultation and risk assessment process. The following ha-ards are commonly associated withexcavation work and will be considered by the risk assessment process

!a" the fall or dislodgement of earth and rock!b" the instability of the excavation or any adjoining structure!c" the inrush or seepage of water!d" unplanned contact with utility services eg, electricity

!e" the placement of excavated material!f" falls into excavations!g" the movement and positioning of heavy plant and e(uipment a$ecting the excavation!h" ground vibration a$ecting the stability of the excavation!i" vehicle movement!j" excessive noise from the operation of machinery and plant!k" manual handling injuries!l" changes to excavation conditions.

4.1 PRE$ENTION OF COLLAPSE OR FAILURE OF TRENCHES AND OPEN E%CA$ATIONS3 risk assessment will be conducted to determine which controls will be implemented to preventpersons being injured by collapse or failure of all or part of a trench or open excavation. %t willconsider at least the following

!a" the depth of the excavation/!b" the nature of the strata 8 sand, clay, shale, ?oaters, etc. including their likely behavior upon

exposure to the elements/!c" fractures or faults in rock.!d" the presence of moisture or water/



4/11

!e" the possibility of exposure to wet weather and water from other sources/!f" any load close to the edge or in the -one of in?uence of the excavation/!g" vibration/!h" the exposure time/!i" any previous disturbance of the ground, eg previous excavations/ and!j" adjoining buildings or structures @emoval of soil from an excavation causes unbalanced soil

stresses which reduce the capacity of the excavation to support itself.

There may be additional geotechnical engineering issues that will be considered. 3ccordingly wherethe risk assessment identies the risk of an unstable condition, the following measures will beconsidered before starting excavation work

!a" seeking advice from appropriately (ualied engineers,!b" carrying out a geotechnical analysis,!c" engaging a competent person to supervise the progress

of the excavation work. Shoring systems, benching and battering are engineering issues thatinvolve both structural design and soil mechanics. The use of ade(uate shoring, benching andbattering is essential to control the risk of a collapse or failure of a trench or open excavation.

4.2 DESIGN OF ENGINEERING CONTROLS7esign specications for engineering controls such as shoring support structures, benching orbattering will be prepared by an appropriately (ualied person in accordance with relevant standardsand codes. %n developing specications, at least the following factors will be considered

!a" the si-e and strength of the component members of the shoring!b" existing and changing ground conditions!c" the loads and types of ground or soil conditions to be shored!d" static loads near excavation, eg. spoil pile, buildings and structures!e" dynamic loads near excavation, eg. tra'c and excavation e(uipment!f" ground vibration, eg. heavy tra'c, mobile plant, and pile driving.!g" di'culties or risks that other services may pose ie overhead power lines, existing or proposedunderground services!h" working environment such as exposure to dust, noise, water,!i" that systems of work are in accordance with any re(uirements of the *S+ regulations!j" location of utility services!k" safety during installation and removal.

4.3 SHORING&here necessary, all trenches and excavations will be ade(uately shored or supported to prevent afall or dislodgement of earth, rock or other material forming the side of or adjacent to, any excavationwork from burying, trapping or striking a person that is in the excavation. &here such a risk alsoexists for those installing supports, other appropriate control measures will be in place to ensure thesafety of persons entering the excavation. 3 shoring system will not be re(uired if, having regard tothe nature and slope of the side of the excavation and other relevant circumstances there is noreasonable likelihood that earth, rocks other material will fall or dislodge from a height ofmorethan.9m and bury, trap or strike a person that is in the excavation. The risk assessment processwill be used to identify unstable conditions and the risks involved. Shoring the face of an excavationwill proceed as the work of excavation progresses. &here a mechanical digger is used, the riskassessment will be used to determine whether any part of the trench may be left unsupported.Shoring may include any suitable system of temporary support sand sheeting material used to

maintain the stability of the sides of an excavation. The installation and removal of shoring will takeplace from outside an excavation.

4 .3.1 REMO$AL OF SHORING SUPPORTS&hen removing shoring, the support system will be extracted 1 dismantled inthe reverse order of itsinstallation. Persons performing the work in the excavation will not work outside the protection of theground support system.

4 .4 BENCHING AND BATTERING E%CA$ATION #ALLS2oth benching and battering of excavation walls are methods of work which may be used to minimi-ethe risk of the soil or rock slipping onto the excavation. %f battering is implemented, it will commencefrom the bottom of the excavation. &hen benching or battering the walls of an excavation, an angleof repose of 69 degrees will not be exceeded unless certied in writing by a geotechnical engineer.

4.5 INSPECTION OF SUPPORT SYSTEMS&here risks or ha-ards that create a risk to health and safety of those carrying out the work areidentied, they will be controlled prior to any further work being carried out. This may re(uire furtheradvice from geotechnical and design engineers to review the ade(uacy of the control measures in



5/11

place. The risk assessment will be reviewed at all terms during the excavation works. The followingconditions will be considered or monitored!a" shoring becoming unstable!b" shoring components not secure or failing!c" angle of batter remains su'cient to prevent collapse!d" premature removal of shoring!e" workers in excavations venturing outside the connes of shoring, benching or battering!f" cracks appearing near the edge of an excavation

!g" excavated and other material being placed within the -one of in?uence of the excavation!h" machinery operating within the -one of in?uence of excavations causing weight and vibrationin?uences!i" surface soil falling into the excavation!j" water seeping into excavations from its side walls or base!k" changes to soil and1or weather conditions!l" extra loading!m"surface water or run8o$ entering the excavations or accumulating on surface near the excavation!n" inclined bedding planes AdippingB into the excavation!o" heaving or swelling of the ground at the bottom of the trench!p" subsidence alongside the excavations!(" unsafe access or egress!r" exposure of contaminated ground

!s" undercutting of the excavation

4 . SECURITY OF E%CA$ATIONS3 risk assessment will be conducted in order to determine which controls will be implemented toensure the security of excavation both during work and when left unattended. The control measuresimplemented will be appropriate and e$ective for the ha-ards and risks of the situation. )onsiderationwill be given to factors such as how long the excavation will be open, and who may gain access to theexcavation. The following control measures will be considered!a" isolating the ha-ardous area, such as by the use of perimeter fencing, barricades, screens,barriers, handrails and1or covers, which are capable of preventing access or preventing the fall of aperson!b" removal or lowering ladders on work site!c" immobili-ation of plant to prevent unauthori-ed use!d" compliance with relevant *S+ re(uirements.!e" ha-ard warning lights, signs, markers or ?ags!f" site security measures, including fencing or use of safety observer!s"!g" night lighting.Signs will be erected around the site showing the name and contact telephone number !includingafterhours emergency number" of the principal contractor1contractor emergency numbers.

4 ..1 FALL PRE$ENTION3 safe system of work and appropriate control measures will be provided wherever persons areexposed to a risk of falling during excavation work. %t is a *S+ re(uirement to e$ectively fence allexcavations and holes more than.0m deep. %t will also be noted that all platforms, open sides ofstairways and stairway landings will be fenced. %n addition to the security measures listed above, the

following measures to prevent falls will be considered!a" use of intermediate platforms for deep excavation!b" provision of a safe means of movement between di$erent levels of the excavation!c" provision of an ade(uate fall arrest system!d" backlling as work progresses )ontrol measures will be properly installed and maintained until thework is completed or until there is no longer any risk of persons falling into the excavation.

4 ..2 PRE$ENTION OF DRO#NING&here, during excavation work, and excavation is likely to collect or retain water so as to create aha-ard to persons in the vicinity, the excavation will be covered or fenced o$. )ontrol measures willbe provided where there is a risk of a person drowning as a result of a fall into water or other li(uid,e.g. slurry. The following measures will be considered!a" provision of positive means of fall protection such as fencing, handrails and safety harness

principal contractor and also provided to the contractor and operator carrying out the excavationwork. The contractor will allow for inaccuracies and the possibility of other unknown or hiddenservices. =urther, the principal contractor will arrange for these services to be clearly markedaccording to the available plans and on site checks prior to commencement of work. Services will beexposed at su'cient intervals to positively identify their location and1or lie. The following are ways ofchecking for underground services!a" using remote location devices!b" hand digging, using hand tools with non8conductive handles. 3ll persons whose work may be

a$ected by an underground service will be advised of the location of every underground service.3ppropriate control measures will be implemented after consultation with relevant service providers.These measures may include the protection, support or removal of services to ensure safety ofworkers.

4 ." E%CA$ATIONS AD&ACENT TO BUILDINGS OR STRUCTURESThe contractor will ensure that excavation work which is likely to reduce the security or stability ofany part of any building or structure will not be commenced or continued unless ade(uate steps aretaken before and during the progress of the work to prevent danger to any person from collapse ofthe building or structure or a part of a building or structure. %n assessing the risk, measures such asthe following will be considered before starting excavation work!a" seeking advice from appropriately (ualied engineers!b" undertaking a geotechnical analysis

!c" engaging a competent person to supervise the progress of the excavation work!d" underpinning of structures!e" construction of e$ective retaining walls!f" minimi-ing ground disturbance and vibration by taking into account the location of machinery, these(uence of work, the impact, severity and scale of excavation!g" backlling as work progresses!h" evacuation of a$ected areas. The contractor will also ensure the stability of vehicular access whichmight be a$ected by the work.4.' PROTECTION AGAINST RISING, IRRUPTIONOR INRUSH OF #ATEROR MATERIALThe contractor will ensure that where there is risk from rising water or from an eruption of water ormaterial, the means to enable every person to reach a position of safety will be provided. %f a riskassessment reveals a risk of rising, irruption or inrush of water or material, appropriate controlmeasures will be provided.

4.10 MATERIALS AND LOADS ABO$E AND NEAR E%CA$ATIONSTo reduce the risk of excavation collapse, excavated or other loose material will be e$ectively storedor retained away from the excavation. +xcavated material will be placed outside the -one ofin?uence. 3lternatively the support system will be designed to accommodate such additional loadincluding ground water pressures, saturated soil conditions and saturated materials. Mechanical plant,vehicles, storage of materials or any heavy loads will be prevented from approaching within orencroaching on the -one of in?uence of the excavation unless the support system has been

specically designed for such loads. &here the risk assessment has identied a risk of collapse as aresult of loads or materials above or near the excavation, shoring will be in place before any personenters the excavated area. The following measures will also be considered before starting excavationwork!a" controlling access to exclude persons from ha-ardous areas, e.g. relocating means ofaccess!b" moving and storing loads outside the -one of in?uence of the excavation!c" provision ofwheel stoppers to limit movement of mobile e(uipment adjacent to the excavation!d" reducing thenumber of trench shields stored near excavation by pulling along trench shields and backlling as theexcavation progresses !e" securing all loose materials in place. &hen working on a slope, a riskassessment will be conducted to determine the safest side of the excavation to dump soil andexcavated material. This will often be on the lower side of the slope to reduce the risk of wall collapseor material falling into the excavation. Site factors will be considered.

4 .11 PROTECTION FROM FALLING OB&ECTS

The risk assessment will be used to determine appropriate control measures toprotect persons fromaccidental falls of objects including tools, plant and other construction materials. 3s far as practicable,loads will not be suspended or travel over a person.
