1 PURPOSE

The purpose of this standard is to eliminate potential harm to all employees, contractors and visitors on all

WMC sites resulting from persons falling from one level to another or being affected by falling objects.

2 SCOPE

This standard applies to:

§ All WMC operating sites and offices.

§ All employees, contractors and visitors.

This standard sets out minimum requirements. Where a local regulatory or industry standard gives morestringent requirements, then that standard shall be used.

3 INTRODUCTION

This standard requires that a system of work for prevention of falls from height is established andmaintained.

This can be achieved through:

§ where practicable, the elimination of the need to work where there is the risk of a fall.

§ conducting Risk Assessments before the commencement of work and at any time the scope of work

changes or the risk of a fall increases.

§ selection of appropriate control measures using the hierarchy of controls.

§ ensuring all equipment used is fit-for-purpose.

§ ensuring all persons responsible for, or performing work, where there is a risk of falling, are competentin the correct use of the site management systems for the prevention of falls.

§ development of procedures for the design, construction, use and disposal of all equipment that

supports or lifts a person at height.

§ the use of fall arrest equipment as the last option for a control measure (after all other controlmeasures have been explored and deemed to be inappropriate) where it is not practicable to eliminate

the risk of a fall.

4 DEFINITIONS

Work at Height

“Work at Height” is defined as whenever people are at risk of falling from, into or through one level toanother.

Fall Injury Prevention Systems (FIPS)

A system designed to arrest or prevent a persons fall from one level to another whilst minimising the risk ofinjuries or harm during the fall. FIPS include fall restraint systems, fall arrest systems, catch platforms,scaffolding, safety nets and safety mesh.

Total Restraint





A situation where a fall is not possible achieved through control of a persons movement by means of acombination of a belt or harness, a line and a line anchorage which will physically prevent the person from

reaching a position at which there is a risk of a free or limited free fall.

Restrained Fall

A fall or the arrest of a fall where the person falling is partially restrained by a device such as a pole strap, or

is sliding down a slope on which it is normally possible to walk without the assistance of a handrail orhandline.

Limited free fall

A fall or the arrest of a fall where the fall distance before the fall arrest system begins to take any loading,does not exceed 600mm either vertically or on a slope on which it is not possible to walk without theassistance of a handrail or handline.

Free Fall

A fall or the arrest of a fall where the distance before the fall arrest system begins to take any loading, is inexcess of 600mm either vertically or on a slope on which it is not possible to walk without assistance of a

handrail or handline.

Anchorage Point

A secure point of attachment on a structure to which an approved safety harness or fall restraint / fall arrest

device, or lanyard, or lanyard assembly or static line may be secured.

Approved Safety Harness

A full body harness of the parachute style with as a minimum a fall arrest attachment point at the top dorsal

position, which was manufactured and complies with AS1891.

Lanyard

A lanyard is used to connect an approved safety harness to an anchorage point or static line in situations

where there is a risk of a fall or when used in restraint mode to prevent a fall. Lanyards can be eitheradjustable or fixed length and incorporate the use of a shock absorber.

Static Line (Permanent or Temporary)

A horizontal safety line or rail system to which a lanyard may be attached and which is designed to arrest afree fall. (as per AS 1891.2)

Approval to work at height

A document authorising a person to perform a task where it has been deemed necessary to work in a fallarrest harness and lanyard in a situation where there is a potential for free fall. The Authority is completed bythe individual doing the work, reviewed by the Emergency Response Coordinator and is authorised by the

relevant Superintendent.

5 RESPONSIBILITIES

5.1 Registered Manager

APPENDIX A

Hierarchy of Controls

WORKING AT HEIGHTS

Users of fall prevention equipment need to be aware how these systems are placed within the hierarchy of

control for fall prevention, so that an assessment can be made as to whether the highest practicable level of

protection is being applied in a particular case. The following explains this hierarchy of control.

Elimination - Eliminate the need to access the fall-risk area, e.g. by locating or relocating items requiring

inspection, maintenance or other attention, elsewhere.

Substitution - Provide alternative means of access to the point or item to which access must be made which

avoids the risk of a fall e.g. walkways.

Engineering/Isolation - Barricade or enclose the fall-risk so that it cannot be reached hard bunting, handrail

scaffolding.

Administrative controls are required for all steps; Take Time Take Charge, THA, SWP, “Approval to Work at

Height”, training etc.

Fall Prevention PPE - Must only be considered as a last resort and only if all other control measures are

impracticable, unavailable or will introduce further hazards to the work. Provide PPE which either prevents a

fall or reduces risk or severity of a fall (the hierarchy of fall prevention options are described below).

FALL PREVENTION

When identifying personal fall prevention equipment as a control it shall be considered using the hierarchybelow.

1) Fall Restraint

Equip operators with personal restraint equipment designed to allow access to work areas without

encountering risk of a fall.

2) Work Positioning

Enclose or encapsulate operators in work positioning devices such as EWP, workboxes or support them by

means of industrial rope access

3) Limited Free Fall

Equip operators with personal fall-arrest equipment which will not prevent a fall but will limit the distance and

severity of the fall; inertia reels, retracting lanyards fall distance is < 600mm

4) Free Fall – LAST RESORT

Equip operators with personal fall arrest equipment which will not prevent a fall but minimise the risk of injury

in the event of a fall maximum 2 metre free fall.





APPENDIX B

APPENDIX C

Fall Injury Prevention Systems

ANCHOR POINTS

Anchor points are used to attach Fall Arrest harness worn by a person via a connecting lanyard. Anchorpoints used in Fall injury prevention systems shall meet the following specifications (minimum):

§ Total restraint - capable of withstanding a minimum of 6kN.

§ Restrained fall - capable of withstanding a minimum of 6kN

§ Limited free fall - capable of withstanding a minimum of 12kN

§ Free Fall - capable of withstanding a minimum of 15kN, or

§ Capable of withstanding a minimum of 21kN if two people are attached to the same anchor point.

Anchors for limited or total free fall shall be located above head height of the person and located in a centrallocation (within 30 degrees from vertical) that prevents a pendulum swing.

Anchor points shall also have the required clearance below the worker for the type of system beingemployed. (Eg length of lanyard, + tear out distance, height of user + safety margin.)

Fall arrest anchor points that will be in place for a period of longer than one month shall be signposted in

accordance with the requirements of AS 1891.4.2000 section 3.2.5. Ladder rungs shall not be used asanchor points. Handrail components shall not be used as anchor points.

Note: When considering the strength requirements for static lines, the anchor attachments to the structureshall also be considered.

The maintenance of anchor points shall be:

§ Pre-use inspection by the user.

§ For permanent anchors in any surface plant in general areas a 12 monthly integrity check via prooftesting.

§ For permanent anchors in either the underground or an aggressive surface environment a 3 monthly

integrity check via proof testing.

STATIC LINES

Static lines are used where a range of movement is required in one longitudinal direction. A typical example

being whilst repairing or painting a roof where free movement along the roof is required but persons need tobe prevented from falling off the edge of the roof. Static lines can be used as anchor points for either fallrestraint or fall arrest equipment.

They shall be either:

§ Permanent 12mm diameter steel (generally stainless steel) cable attached to permanent anchors or;

§ Temporary systems that use 20mm diameter flexible rope that is suitable for such use. Ordinary rope

shall not be used.

Anchor points for static lines shall be:

§ Designed, approved and checked after installation by a structural engineer





§ Designed in accordance with line anchor requirements of AS 1891-2 Horizontal life lines and railsystems.

A number of commercial temporary static line systems are available which include attachment and

tensioning devices. Only those systems that comply with AS1891 shall be used.

Maintenance of static lines will depend on its frequency of use and where it is used. However:

§ For permanent static lines the minimum maintenance shall incorporate integrity checking of the cableand proof testing of the anchors every six months. Greater inspection frequency shall occur inaggressive environmental conditions.

§ For temporary static lines, all components shall be checked prior to use, paying particular attention toany fraying, cracking or cuts in the rope. The attachments shall be checked for distortion, cracks orsharp edges where the rope contact occurs.

§ Emergency response coordinators shall be consulted and involved in the installation and use of allstatic line systems.

LANYARDS

Lanyards are used to connect persons who are wearing either fall restraint or arrest equipment to an anchorpoint. There are several types, being fixed length, shock absorbing and inertia reel retractable, which aredetailed in the section below. All lanyards shall comply with the relevant Australian Standard for their type.

Those using a lanyard shall ensure that it is suitable for the proposed use and that it will provide the requiredfall restraint or arrest.

Fixed length lanyards are used in either fall restraint or arrest situations. For fall restraint, the length needs to

be such that at maximum length it prevents the person getting too close to any edge where the person couldfall. For fall arrest, the summed length of the lanyard, the expanded shock absorber, the person and a 1

metre safety margin, does not exceed the height that the person can fall.

Shock absorbing lanyards can be used in either total restraint or free fall arrest situations. If used in free fallarrest mode the above calculation for sufficient clearances must be accounted for.

Endless loop lanyards (snake slings) are used to wrap around structural beams etc. in order to provide an

anchor point for either fall restraint or arrest. An endless loop lanyard shall not be choked (one end threadedthrough the other) rather both ends shall be placed in the attachment device of the attaching lanyard.

Lanyards must be checked for compatibility of all components including the harness attachment point and

anchor attachment point to prevent the potential for either crush out or roll out occurring.

All lanyards, with the exception of the endless loop, shall be fitted with either double acting snap lock hooks

or screw gate karabiners.

It is important to inspect the work area where the lanyards will be used to ensure that they will not bedamaged by sharp edge on beams or sheet steel, dangle in pools of water, oils or chemicals or that thehooks or karabiners do not become jammed up with dust or crushed rock.

The maintenance on these items shall be:

§ Pre-use visual inspection for cuts, abrasion, heat or oil or chemical damage and currency of operatinglife, which shall not exceed ten years from manufacture.

§ Pre-use check of the condition of the hook or karabiner to ensure that they operate freely, do not jambopen and are not bent or damaged in any manner.

§ For shock absorbing lanyards, a pre-use check that the shock absorber has not opened in any mannerindicating that it has arrested a fall.





INERTIA REEL ARREST DEVICES

Inertia reel arrest lanyards range in size and type from the short fibre to the longer retracting wire type. All

retracting lanyards shall comply with their relevant Australian Standard.

They are particularly suitable where good flexibility in a working area is required whilst still achieving themaximum of 30 degrees (from the vertical) angle for the mounting of fall arrest above a person wearing a fall

arrest harness. They are advantageous where persons climb up and down a structure as part of their worktasks.

Inertia reels can only be used for fall restraint when the maximum reeled out length of the device does not

exceed the distance to the edge where a person can fall. It is not acceptable to rely on the auto-lockingmechanism to restrict a person in a fall restraint mode (eg Do not lock off and lean on the device).

Persons using an inertia reel device shall:

§ Conduct a pre-use inspection of the whole length of the inertia reel, checking for cuts and tears on

fibre type and damaged, “bird caged” or broken wires on wire type devices.§ Check the inspection tag to ensure that a formal inspection has occurred within the last 3 months.

§ Check for damage on the housing and cable or fibre entry point.

§ Check for the correct and immediate operation of the locking devise when a quick pull is applied to it.

The maintenance required on these items includes:

§ A formal and documented inspection each 3 months conducted by a competent person. Each fourth, 3monthly inspection (i.e. annually) shall also involve an internal inspection of the device, againconducted by a competent person.

§ Tagging of the device to indicate that the inspection has occurred.

SAFETY CLIMBING SYSTEMS

Safety climbing systems are essentially a vertical static line that runs up the middle of the ladder. They must

comply with AS1891.

They are generally used on long fixed ladders on items such as stacks, drill rigs, radio towers etc. A personwearing a suitable harness connects to the static line via a short lanyard and a running attachment device.

In the event of the person losing their footing, the attachment device grabs the wire and stops the personfalling.

Persons using such devices shall be:

§ Trained and deemed competent in the use of them paying particular attention to installing the running

attachment device correctly.

§ Carry out a pre-use inspection of the running static line and continuous inspection as they climb.

The required maintenance on the system is the same as for static lines detailed above.

BELAY SYSTEMS

Belay systems are used either for emergency purposes or for specialised maintenance inspections.

Whenever they are used for emergency purposes, their use is controlled by relevant emergency rescueprocedures.

When used for specialised maintenance activities, competent and experienced contracting organisations are

used to perform the required tasks after consultation with site emergency response coordinator to establishsafe systems of work.





APPENDIX D

Personal Protective Equipment

PERSONAL FALL ARREST EQUIPMENT (TOTAL RESTRAINT)

Personal fall restraint equipment shall:

§ Comply with AS1891.1 and shall not be greater than ten years old

§ Be inspected prior to each and every use

§ Have a formal documented inspection performed by an authorised, competent person at intervals notexceeding 3 months

§ Only be attached to an anchor point meeting the requirements of Appendix C.

Typical uses include:

§ Fall restraint of underground miners inspecting an open stope edge

§ Persons working on a low angle pitched (not greater than 5 degrees) roof or within 2 metres of an

open edge or opening

§ Any other location where persons are working within 2 metres of an edge where the fall from theheight could result in an injury.

Persons using fall restraint equipment shall:

§ Have been trained and assessed as a competent user of such equipment

§ Perform a visual check on the fall restraint equipment prior to fitting it. Ensure that it has been fullyinspected and tagged within the previous 3 months.

§ Perform a visual check on the lanyard for any cuts, abrasions or heat damage and if any faults arefound tagged “Out of Service” and arrangements made for a competent person to conduct a formal

inspection.

§ Perform a visual check on the attachment point that will be used and if found unsuitable, not use it asan anchor point.

§ Connect to the attachment point prior to undertaking any work activity.

§ Ensure that the diameter of the “D” hook on the belt exceeds the throat depth of the attachment hookon the lanyard to prevent “roll out”.

§ Only use a retractable lanyard where its maximum length does not allow the person to be in a positionwhere a fall is possible. Alternatively use a length of flexible rope fitted with a self-locking rope graband karabiner.

§ Ensure that all components of the fall restraint system are compatible.

§ Ensure that all components of the fall restraint system are stored in a suitable location to preventdamage or early deterioration.

PERSONAL FALL ARREST EQUIPMENT (LIMITED FREE FALL / FREE FALL)

Persons wear personal fall arrest equipment in order to arrest their fall should they fall from their workingarea. This type of equipment shall only be used when all other control measures have been explored and

deemed to be inappropriate. The equipment typically consists of a full body harness connected to an anchor

point via either a retractable or fixed length lanyard fitted with a shock absorber.





Fall arrest equipment can only be effective if the free space below the level at which the person is working is greater than the summed length of the person plus the lanyard, plus the expanded length of the shock

absorber plus a safety margin of 1 metre. The minimum distance being 6 metres (7 metres if the anchor point is a static line). Persons shall calculate the actual distance based on the equipment they will use prior

to its use.

Personal fall arrest equipment shall:

§ Comply with AS1891.1 and shall not be greater than ten years old.

§ Be inspected prior to each an every use.

§ Have a formal documented inspection performed by a competent person at intervals not exceeding 3months.

§ Only be attached to an anchor point having the following features:

- Be located above the wearer’s head and be within a maximum of 30 degrees from the vertical ofthe working area of the person.

- Be of sufficient strength to withstand a breaking force of 15kN. (15kN equals 1.5 tonne in staticload applied to one point)

- Where permanent, anchor points shall be designed by a suitably qualified engineer and complywith AS 1891.4. They shall be identified as an anchor point with a sign and have their SWL

detailed on that sign.

- Where mounted with chemical or friction anchor bolts they shall be proof tested in compliancewith AS1891.4.2000 part 3.1.3 (g).

- Where rock anchors are used, they shall consist of two offset eyebolts with a combined strengthof 21kN and must not have been used for any other purpose.

- A vehicle that has a mass in excess of 2 tonnes, and is properly parked, with a Personal Danger

tag and lock attached to the battery isolator which has been switched off. The attachment shall

be to a main structural member of the vehicle and NOT to the tow ball or tie down hook.

- Consist of a closed loop hook eye and must allow for the direct attachment of the safety device.

Alternately, an endless loop lanyard can be wrapped around a suitable size steel structure(capable of holding 1500Kg) and the lanyard directly connected to both ends of the endless looplanyard. Do not choke the endless loop lanyard.

- Be a “Static Line” as long as it has been correctly designed and installed.

- NOT be ladder rungs, handrails, cable tray support etc.

- If scaffold is used as an anchor point:

- Double scaffold tubes to be installed on the horizontal (ledger or transom)

- Additional safety scaffold clips to be installed under the normal standard/ledger clip onthe vertical upright (standard) to prevent slipping

- Additional bracing to be installed

- The distance between standards is not to exceed 1.8mtrs

- Be the hook of a certified crane that is rated appropriately for the job and has been isolated so

that it cannot be operated or moved.

Persons using fall arrest equipment shall:

§ Have been trained and assessed as a competent user of such equipment.

§ Ensure that there is sufficient height to allow the fall arrest system to function correctly, by not allowingthe person to hit the ground or other structure, should a fall occur. As a minimum this requires 6

metres of clearance.

§ Obtain a formal documented “Approval to Work at Height” from their line superintendent or equivalent.





§ Develop and have approved by site emergency response coordinator an appropriate task specificemergency rescue plan. A person whose fall has been arrested by fall arrest equipment must be

rescued quickly and efficiently otherwise serious injury can occur.

§ Perform a visual check on the lanyard for any cuts, abrasions or heat damage. For retractablelanyards, pull out its entire length and check it. If any faults are found then the equipment shall be

tagged “Out of Service” and arrangements made for a competent person to conduct a formalinspection.

§ Perform a visual check on the full body harness prior to fitting it. Check that the harness complies with

AS 1891.1. and that it is within 10 years from manufacture. If any faults are found then the equipmentshall be tagged “Out of Service” and arrangements made for a competent person to conduct a formalinspection.

§ Ensure that it has been fully inspected and tagged within the previous 3 months.

§ Perform a visual condition check on the anchor point that will be used and if found unsuitable, not useit as an anchor point.

§

Connect to the attachment point prior to undertaking any work activity.§ Ensure that they only use the attachment point positioned between the shoulder blades on the back of

the harness. All other D hooks on the harness are either for rescue or for use in fall restraint.

§ Ensure the diameter of the “D” hook on the harness exceeds the throat depth of the attachment hookon the lanyard to prevent “roll out”.

§ Ensure that all components of the fall arrest system are stored in a suitable location to prevent

damage or early deterioration.





APPENDIX E

Mobile Work Platforms

Purpose designed mobile work platforms such as:

§ Elevated Work Platform (EWP) sometimes called a cherry picker;

§ Scissor lifts.

Engineered additions to mobile equipment such as:

§ Baskets for Integrated Tool (IT) carriers;

§ Work platforms for Forklift trucks.

The design, manufacture, operation and maintenance of the above equipment are regulated by a number ofdifferent statutory requirements and compliance with these is essential.

Persons using such equipment shall:

§ Be trained and assessed as competent to use it. Refer Appendix B.

§ Conduct a daily pre-start inspection of the machine and log the results in either the machine logbookor equipment pre-start book. If the machine is found to be faulty, then it shall be tagged “Out ofService”.

§ Use it for its designated purpose and within its designed operating limits of both reach and weightcarrying capacity.

§ Where required wear either fall restraint or fall arrest equipment.

- For EWP (Boom type) a Fall Arrest Harness shall be worn at all times. Travel in the raisedbasket only allowed at creep speed. Travel in lowered basket allowed at normal speed;

- For a scissorlift with any side missing then Fall Restraint equipment shall be used at all times;

- For a scissorlift with all sides in place no Fall Restraint equipment is required and travel ispermitted only at creep speed and whilst performing specific duties, not travelling betweenplaces of work.

§ Not access or exit any platform or basket while it is in the raised position, unless no other safe accessexists and then only after a safe system of work has been developed after completing anddocumenting a thorough risk assessment and an “Approval to Work at Height” obtained.

§ Comply with specific training and site or area restrictions for the operation of the equipment. Thisespecially applies to acceptable travel way slope and condition.

§ Only stand within the basket or on the floor of the platform and not on handrails, ladders, scaffolding or

boxes in order to gain extra height.

§ Not work closer than 10 metres to exposed overhead power lines unless a powerline access permithas been authorised and obtained.

§ Have a separate person operating the machine controls where the platform is attached to an item ofmobile equipment. Examples include IT basket or platform on a forklift.

§ Use an acknowledged signalling system between the person in the elevated basket or platform and

the person at the controls where such a situation exists.

§ Ensure that where attachments fit to items of mobile plant that:

-

Only the correct machine/attachment arrangement is used.- For ITs carrying work platforms, its lift cylinders are fitted with check valves.





- The attachment will not accidentally disconnect while the platform is in service.

- They are a correctly engineered and manufactured attachment.

- Whilst persons are being carried within them, they cannot be ejected from them.

§ If any faulty item of a mobile platform cannot be repaired, then sale of either the whole machine orscrapping of the individual component involved in being a work platform shall occur. If an item is sold

with a fault the fault shall be documented in order to make the potential purchaser aware of the fault.

NOTE: At no time is it permissible to use either a wheeled loader bucket or a pallet on a forklift as aworking platform.





APPENDIX F

Scaffold

Scaffolding shall:

§ Comply with AS1576, AS1577 and AS4576.

§ Be constructed and maintained by a competent scaffolder who has completed a THA beforecommencing erection or dismantling.

§ Be constructed and dismantled in such a manner that ensures correct lifting or lowering of sectionsand as far as is practicable does not place the person(s) erecting or dismantling it at a risk of fallingfrom height or for items to fall from height.

§ Be constructed using correct lifting stillages etc. where the scaffolding material is tied into place to

prevent it falling whilst being lifted.

§ Be modified only by a competent scaffolder.

§ Be built to the sufficient strength rating based on the estimated weight of the persons and equipmentthat shall be positioned onto it.

§ Have access ladders fitted to prevent persons accessing by climbing the structure.

§ Be fitted with a red Scaftag during construction and a signed and dated green Scaftag on completion.

§ Be clearly marked with its load capacity on the Scaftag.

§ Be re-inspected every 14 days or sooner if either environmental or workplace conditions are likely to

effect the condition of the scaffolding. A competent scaffolder shall perform the inspection and shallre-sign and date the yellow side of the Scaftag. If any faults are noted that cannot be immediately

rectified then the Scaftag shall be removed from the holder thus leaving the red “Danger do not use”component of the Scafftag system.

§ Be adequately guarded or barricaded where the scaffold has to be erected either partially or totallyabove or on a roadway or person access way.

§ Not be erected or dismantled within close proximity of electrical equipment such as transformer, busbars etc. without seeking the advice of the Electrical Supervisor.

§ Any faulty item of scaffold equipment that cannot be effectively repaired shall be cut up and disposed

of as scrap.

Working Platform

§ The minimum clearance above landings shall be 1850 mm.

§ Every access landing shall have 450 mm clear around the landing point.

§ The clear width of an access to the platform, measured between the guardrails shall be:





Each deck shall be installed from below, while standing on either the ground or a deck enclosed by railprotection. Before erecting the new deck, the next level of standards and handrails shall be installed by the

scaffolder who will be in a safe position one metre above the existing deck.

For single bay scaffolds and internal access bays, the permanent deck shall remain in position every 2metres. One plank may be left out of this deck to allow for equipment to be passed through to the next level.

All enclosed lifts are to be left enclosed until the scaffold is stripped. Prior to approving the scaffold for use,all access decks shall have the final plank installed.

For multiple bay scaffolds, the technique is the same except that planks may be retrieved from below a

completed deck provided the scaffolder remains in a protected position on a deck at the adjoining bay. Thisalso requires that an internal handrail be installed, separating the bays.

All internal access bays shall be enclosed at each 0.5 metre lift for edge protection.

By following this above requirement, the scaffolder will at all times be working within handrails and on adeck, and will not need to be attached to a restraint or anchorage point. If however, rail and deck protection

cannot be constructed as described above, the scaffolder shall be attached to a suitable restraint anchoragepoint.

§ Stair access bays shall be erected/dismantled using mechanical means wherever possible to installstairs. (Eg: crane, jenny wheel, winch)

§ While the risk of tools and or equipment falling during the construction of a scaffold exists, the areabelow shall be barricaded off to prevent any pedestrian being struck by tools or equipment that couldpotentially fall.

§ Scaffolders involved in the construction of the scaffold shall remain in a safe position at all times,where the risk of being struck by either falling equipment or a tool is minimised.

§ Pedestrians and all other persons must be protected from the potential of falling equipment at all

times. This may require the construction of safety nets or hoardings prior to working above the area.

§ Tool restraints may be required at times to protect other persons, however if this is necessaryconsideration shall also be given to the risk of other equipment that could fall, for example tubes and /

or couplers being used to construct the scaffold. If there is unacceptable risk to any person fromeither scaffolding equipment of tools falling, another work method shall be established.

Persons working on scaffold platforms complying with the above shall:

§ Check the Scaftag for currency prior to checking the scaffold for general condition. If any faults arenoted then turn the Scaftag to the red side and request a competent scaffolder to check thescaffolding.

§ Only access the scaffolding via its fitted ladder or stairway.

§ Only use the scaffold to its maximum load capacity.

§ Ensure that their work activities do not allow tools or materials to fall onto persons below.

§ Not use the scaffold as an attachment point for lifting equipment such as chain blocks etc, unless acompetent scaffolder has installed it as a lifting device.

§ Where scaffolds are fitted with wheels, the wheels shall be locked whenever the scaffold is being

used.

§ Not use a mobile scaffold where either it or persons on it will come in close proximity to live electricalequipment such as bus bars etc.





APPENDIX G

kickboard, or

- a top rail at a minimum of 900 mm and infill panels suitable to prevent falls

Persons working on fixed platforms shall:

§ Not stand on any of the handrail structure.

§ Not overstretch over the handrails, thus compromising their safe work position.

§ Ensure that where fitted the gate or bar barrier is closed after entering the platform area.

§ Not erect ladders close to the edge of platforms such that they are then higher than the height of thehandrail. If maintenance is required on items such as light poles then alternate methods such asscaffolding or EWP shall be employed.

§ Not at anytime rely on handrail components as an anchoring point for fall arrest equipment.





APPENDIX H

Access Equipment

Access equipment includes fixed ladders and stairways, temporary ladders to scaffolding and portable

ladders in general.

Access equipment is not commonly used as work platforms and then only for very light duty work such aschanging a light globe or when special equipment and control measures are put in place. Typical examples

would include electrical pole work using a ladder, pole strap and work positioning harness.

For all types of access equipment, maintenance schedules shall be established in SAP for the periodicinspection to ensure that they remain in adequate condition to perform their intended task. The frequency of

the inspections shall be determined by:

§ The work environment that they are exposed to.

§ The frequency of their use.

shall provide fall arrest.

§ Have landings / rest points at not more than 6 metre intervals.

§ The angle of the slope of rung ladders shall be not less than 70 degrees to the horizontal. It should be

not greater than 75 degrees to the horizontal. In no case shall the ladder overhang the personclimbing the ladder.

§ Be disposed off by removal and scrapping the structure if appropriate.

If hoops, cages and landings are not appropriate, alternate means of fall injury prevention must be utilised.

Fixed ladders shall be inspected:

§ at regular intervals determined by local operating conditions

§ as soon as practicable and prior to further use following an occurrence that may have affected thestability or adequacy of the ladder e.g. fire, collision, overloading.

§ Prior to use following repairs or modifications

Stairs shall:

§ Have edge protection fitted on exposed sides, returns and intermediate platforms.

§ Be fitted with non-slip nosing on each step.§ Be disposed off by removal and scrapping the structure is appropriate.





Persons using fixed ladders shall:

§ When a ladder climbing system is installed then fall restraint equipment and a work positioningharness are used.

Temporary Ladders to Scaffolding

Temporary ladders used to access scaffolding shall be securely attached to the scaffolding in order toprevent persons using the ladder in any other location.

Persons shall only access scaffolding using such a ladder and shall not either climb up the side of thescaffolding or lean a portable ladder against the scaffolding to gain access.

Portable Ladders

Any ladder that is capable of being transferred from one location to another shall be considered a portableladder. All portable ladders shall be designed and constructed to meet Australian Standard 1892.

To avoid concealment of defects in wooden ladders, clear varnish or oil must be used as a protective coating

instead of paint. Any ladder that is found to be faulty and cannot be effectively repaired shall be disposed ofin a manner that prevents its re-use.

Persons using a portable ladder shall:

§ Inspect the ladder prior to use. Pay special attention to the condition of the ladders rubber feet. Anyfaulty ladders shall be tagged “Out of Service”.

§ Not use “Domestic” rated ladders.

§ Ensure that the load rating, either medium or heavy duty is appropriate for the proposed use.

§ Ensure that the ladder will be positioned on a level and firm ground that is capable of holding theweight of the ladder and the person climbing on it.

§ Where either a single or extension ladder is used, on first climbing the ladder it shall be footed byanother person and the ladder shall be tied off at the top prior to any other task being performed.

§ Maintain three points of contact.

§

Not stand on the top two rungs of the ladder.§ Remain within the vertical supports of the ladder.

§ Items shall not be carried up or down a ladder unless carried in an approved hands free carry bag.

Items of excessive weight shall not be carried up or down a ladder. Any item carried up or down theladder must not affect the balance of the person using the ladder. Consideration should be given tothe use of a rope or other suitable means to haul up tools and equipment

§ Ensure that the metal spreader bar is locked into position on a step ladder prior to using it.

§ Ensure that the correct lean angle is achieved for single and extension ladders by ensuring that theheight of the ladder is not more than 4 times the distance from the foot of the ladder to the edge it is

leaning on. (4:1 Ratio)

§ Ensure that the ladder is returned to a safe and appropriate storage area at the completion of its use.

For wooden ladders store them horizontally 500mmm above the ground.

§ If the ladder is used to perform work from, then a secondary form of restraint is required.





APPENDIX I

Barricades

Barricading should be used to establish a restricted access zone where a high risk hazard exists. Thismeans there is a definite risk of injury or harm if certain safety precautions are not followed

ACCESS

Restricted access zones are designated No-Go Zones and under no circumstance is a person to enter arestricted access zone unless:

§ They have been authorised to do so by their supervisor or authorised person

§ They are fully aware of the nature of the hazard

APPLICATION

Examples of situations where temporary barricading should be used to establish a restricted access zoneinclude, but are not limited to:

§ Work at heights where there is a risk of persons below being affected by falling objects

§ Areas where flooring, handrails or equipment have been removed causing an opening and a risk offalling

§ Holes or excavations which are intended to be left open for some time.

DEMARCATION

A restricted access zone is demarcated by the use of one of the following:

§ Use of hard bunting steel post and rail construction

§ Use of red & white tape

§ Barrier mesh

§ Red flags

§ Use of orange road cones.

In all situations, appropriate signage must be employed in conjunction with the barricading to warn people of

specific hazards. “Authorised Entry Only” signs and completed information tags must be placed at allpotential entry points.





APPENDIX J

via a lanyard to the designed anchor point in the workbox.





APPENDIX K

Roofs

Prior to commencing any work on a roof either a THA or a WRA C shall be performed and this should

consider:

§ The nature of the work to be conducted. Is it a roof replacement or just access to service equipmenton the roof?

§ The condition of the existing roof and support structure.

§ Is the roof material brittle? Examples being Asbestos cement or aged Alsynite.

§ Is there wire mesh installed under brittle roof material?

§

The location of the roof relevant to other areas of the plant.§ The slope of the roof.

§ How tools, materials and equipment will be raised and lowered and stored on the roof.

§ The distance from the edge of the roof that the work will be performed at. If all work is conducted at adistance greater than 2 metres from the roof edge on a flat roof and the roof is sound then no fallrestraint or arrest system is required.

§ How a person will be anchored to a suitable anchor point.

§ How a static line will be installed, tested and maintained if one is used.

§ How access and egress onto and off the roof will occur.

Persons who are going to work on a roof shall ensure that:§ They comply with the controls detailed in the THA or WRAC.

§ The structural integrity of the roof has been determined prior to:

- Moving onto it;

- Storing materials on it;

- Rigging from it.

§ If the roof material is brittle or its soundness cannot be determined then boarding over the brittle orunsound sections shall be installed by a competent person.

§ If work is to be carried out within 2 metres of any roof edge then fall restraint shall be used that

prevents a person coming too close to the roof edge.

§ If extensive roof repairs or replacement work is being conducted, that requires open roof areas to becreated, then a static line shall be installed to provide the required fall restraint. This shall be

continuously adjusted to provide correct fall restraint.

§ The means of gaining access and egress to the roof is a safe practice. Means of access include: -

- Permanent ladders;

- Scaffolding;

- Properly secured temporary ladders.

§ The means of raising and lowering material, tools and equipment is performed in a safe manner.

§ They are not going to be working in close proximately to live power lines.





APPENDIX L

Ceiling Spaces

Prior to working in or accessing any ceiling space a THA shall be conducted. Appropriate control measuresdetermined by the THA shall be implemented.

The THA should consider the following:

§ Access to and egress from ceiling spaces.

§ Atmospheric conditions within the ceiling space.

§ Supporting surface strength and condition

§ Communication.§ Electrical hazards

§ Fire risks.

§ Hazardous materials contamination.

§ Physical effects of working in the ceiling space.

§ Rescue procedures

When moving around in the ceiling space, a temporary platform such as boarding can be used.





APPENDIX N

Open Holes

An open hole is a hole larger than 200mm x 200mm but less than 2 metres x 2 metres or with a diametergreater than 200mm but less than 2 metres. Anything larger is to be considered as an open edge requiringeither fall restraint or arrest as applicable.

Where work activities will either create an open hole or where one exists in a work area a THA or WRACshall be conducted to determine the controls that will be implemented in order to control the hazard. Thingsto consider shall include:

§ The size of the hole that will be created.

§

Is the hole being created in a walkway or just behind an opening?§ What is the lighting around the open hole both during day and night time?

§ What sort of barricading can be used around the hole?

§ What are the work tasks that will be performed in the hole?

§ How will tools, equipment and material be delivered to the persons working within or below the hole?

Persons either creating or working near an open hole shall:

§ Erect the strongest practical barricade either around or over the hole. For temporary openings, a fixedscaffold barrier around the hole is the minimum acceptable protection. (For very short term openings <

1 hr the placement of a sentry to prevent access to the area is an acceptable control)

§ Erect suitable “Danger” signs advising persons of the open hole or open hole below.

§ Ensure that there is a safe means of access and egress into and out of the hole if this is required.

§ Where persons are required to work within 2 metres of an open hole that is not barricaded off with ascaffold or other strong barrier, then they shall wear fall restraint equipment that shall prevent thembeing able to reach the edge of the open hole.

§ Determine how tools, material and equipment are going to be lowered into or lifted out of the hole.

Where the holes provides access to a Confined Space then ensure that all safe work practices for theConfined Space are complied with, including seeking a Permit to Work and Confined Space Certificate.





APPENDIX O
