Review the tasks/hazards and control measures. Additional high-risk tasks or hazards not listed in the SWMS, require a Risk Assessment IMS-05-46 to be completed. All control measures outlined in this SWMS must be referred to and followed at all times. The appropriate Procedures must be followed when performing the relevant tasks. Where the Procedures are referred to in this SWMS, this will form part of the SWMS work methodology. This SWMS cannot be used onsite unless the workplace and task details are recorded in Section D. All workers must Sign the acknowledgment and agreement of the SWMS in Section D. Review SWMS: Foreman and workers ensure that the effectiveness of the control measures is reviewed during the next daily pre-start, tool box meeting and/or if worksite conditions have changed Workers may review the SWMS at any time during the shift and make changes where control measures are not deemed adequate or where reference is required The foreman must instruct the workers that any SWMS reviews and comments are to be returned to the foreman for him to review, communicate and file. Where the review reveals the SWMS remain suitable for use; there will be NO need to develop another, however the review must be recorded in section D and in the Sites Daily Prestart. RESPONSIBILITIES Project Manager Responsibilities: Ensure the foreman is aware of any site-specific hazards & site rules implemented Ensure that all known hazards are included when developing the SWMS for the site or individual work areas. Instruct the foreman to ensure that this site and/or area specific SWMS are reviewed, developed in consultation with the workers and signed before any work commences. Foreman Responsibilities: Review and communicate site specific hazards and control measures outlined in the SWMS. Ensure that the appropriate control measures have been selected and that workers are aware that the control measures selected are mandatory. Complete a Risk assessment for any high-risk task or additional activity that is not listed in the SWMS Ensure Section D has been filled out correctly and that a SWMS is compiled for each area. Ensure all workers have been shown the SWMS and sign acknowledgement in Section D. Monitor the effectiveness of the control measures outlined in this SWMS during the work activities. If they are proving inadequate or not being adhered to, stop the work and install additional controls before restarting the activities. Record any alterations in the SWMS. Ensure workers follow the appropriate Procedures when performing the selected activities. Workers Responsibilities: Follow the SWMS and appropriate Procedures when performing tasks. Stop work and notify the foreman, if you believe the control measures outlined in this document, are no longer adequate. Environmental Responsibilities Introduction to construction site erosion and sediment control The objective; To take all reasonable and practicable measures to minimise short and long-term soil erosion and the adverse effects of sediment transport In this context the terms: ‘reasonable’ means an action based on sound judgement and affordable cost; ‘practicable’ means an action capable of being put into practice with the available means or with reason or prudence. The first rule of ESC The first thing to acknowledge with the Erosion and Sediment Control profession is that there is an exception to almost every rule and recommendation. The fact that a control measure is observed to work well in one location does not mean that it will work well in another location. Similarly, the fact that a control measure fails in one region does not mean that the technique will not be useful within another region. Environmental Duty The environmental Duty applies to all persons and activities on a construction site. Such an Environmental Duty may be described in general terms as: To take all reasonable and practical measures to prevent or at least minimise environmental harm. Application of ‘Common Sense’ Erosion and sediment control practices must represent an appropriate balance between the application of the ideal design philosophy and the application of common sense. No rule or recommendation should be allowed to over rule the application of a unique, site specific solution where such a solution can be demonstrated to satisfy the principle objective and the specified performance standard. Ten key Principles to best practice ESC Key Principle 1 Appropriately integrate the development into the site. Best Practice development planning involves the determination of the appropriate use for a given site and how best to accommodate that land use within a development layout. To achieve this, it is essential to investigate the site conditions including the soil, water, vegetation and topographic features of the property. Key Principle 2 Integrate erosion and sediment control issues into site and construction planning. During the planning of a building or construction project, consideration must be given to how the site layout and construction process can best achieve the principal environmental objective of taking all reasonable and practicable measures to prevent or minimise environmental harm. Key Principle 3 Develop effective and flexible erosion and sediment control plans based on the anticipated soil, weather and construction conditions. Erosion and Sediment Control Plans need to walk a fine line between being formal plans that site operators must follow, and being flexible plans that still allow site personnel to use their ‘common sense’ to: Adjust to changing site conditions Focus on the intent of technical notes rather than their literal meaning Key Principle 4 Minimise the extent and duration of soil disturbance This principle has many benefits, including; Reduced soil erosion Reduced release of fine colloidal soil particles that cause turbit runoff Promotion of the rapid stabilisation and revegetation of soil disturbances Key Principle 5 Control Water Movement through the site The proper management of stormwater runoff during the construction phase is critical to the implementation of effective erosion and sediment control. The importance of stormwater management generally increases with increasing rainfall intensity. This means drainage control becomes increasingly important the closer you get to northern Australia. Key Principle 6 Minimise Soil Erosion Soil erosion is the process through which the effects of wind, water or physical action, displace soil particles causing them to be transported. The Main factors affecting soil scour are rainfall erosivity, soil erodibility, slope length, slope steepness, soil cover and the surface flow conditions (i.e.: flow type, velocity, duration and frequency) Key Principle 7 Promptly Stabilise disturbed areas. A healthy and continuous vegetative cover is one of the most effective forms of erosion control. Most importantly, vegetation protects the solid against raindrop impact erosion. Vegetation also binds the underlying soil to improve its structural strength, improves soil’s infiltration capacity and increases evaporation thereby decreasing overall stormwater runoff. Key Principle 8 Maximise sediment retention on the site It is usually impractical to prevent all soil erosion on construction sites; thus, some degree of sediment control is always required. The primary purpose of most sediment control measures is to trap the coarser sediment fraction. Key Principle 9 Maintain all ESC measures in proper working order at all times. All ESC measures must be maintained in proper working order at all times until their function is no longer required. To assist in achieving this requirement, technical notes and/or construction specification attached to the Erosion Sediment Control Plan (ESCVP) must specify the maintenance requirements of all sediment traps. Key Principle 10 Monitor the site and adjust ESC practices to maintain the required performance standard. Erosion and Sediment Control Plans (ESCPs) are living documents that can and should be modified as site conditions change, or if the adopted measures fail to achieve the required treatment standard. If a site inspection detects a failure in the adopted ESC measures, then the source of this failure must be investigated and corrected. Risk Assessment Risk Assessments should take into consideration - likelihood and consequences of injury, illness or incident occurring & available information on hazard including any records of incidents, illness and disease. Likelihood of event occurring Incident Classification Rare Unlikely Possible Likely Almost Certain One or more fatalities, traumatic or severe disabling injury, damage / theft more than $1,000,000. *A Notifiable Incident Consequence of the event occurring Catastrophic High 15 Extreme 19 Extreme 22 Extreme 24 Extreme 25 Lost time injury (LTI), damage / theft less than $1,000,000 but more than $100,000. * A Notifiable Incident Major High 10 High 14 Extreme 18 Extreme 21 Extreme 23 Medical treatment required (MTI), damage / theft less than $100,000 but more than $10,000 Moderate Medium 6 Medium 9 High 13 High 17 Extreme 20 First aid treatment required (FAI), damage / theft less than $10,000 but more than $1,000 Minor Low 3 Low 5 Medium 8 High 12 High 16 A near miss, no injuries, damage / theft less than $1000 Insignificant Low 1 Low 2 Low 4 Medium 7 High 11 Risk Rating Procedure Following Risk Assessment Control Application Extreme 18 - 25 Activity must not commence. Must eliminate hazard or introduce further controls to further reduce the risk. Any hazard assessed presenting extreme risk level will only be allowed to be controlled using elimination and or engineering controls as the primary source of controls. High 10 - 17 Activity must not commence without Compliance Advisor or higher approval and appropriate supervision by Project Manager or Foreman. Implement strict control measures to further reduce risk. Any hazard assessed as presenting high or medium risk level will only be allowed to be controlled using a combination of at least one engineering control and one lower level controls as appropriate. Medium 6 - 9 Project Manager and Foreman must determine appropriate level of supervision required. Implement strict control measures to further reduce risk. Any hazard assessed as presenting high or medium risk level will only be allowed to be controlled using a combination of at least one engineering control and one lower level controls as appropriate. Low 1 - 5 Monitor, manage and carry out activity in accordance with identified controls. Any hazard assessed as presenting a low risk level will be permitted to be controlled using a combination of controls as appropriate, more than one lower level control must be applied if elimination and or engineering controls are not practicable. Hierarchy Controls Examples Eliminate Can we eliminate or remove the hazard completely Substitute Can we substitute the hazard with something else less dangerous Engineer / Isolate Can we re-design or isolate the hazard completely Administration / Training What controls can we put in place, e.g. training, job rotation, supervision Personal Protective Equipment What personal protective equipment is required to undertake this activity Civil Construction | SWMS CONTROL MEASURES Civil Construction | SWMS CONTROL MEASURES PREREQUISITES and GENERAL WORKS Hazard / Risk Control Measures HAZARDS Lack of awareness of hazards / works onsite Unable to provide Suitable Supervision and monitoring Lack of understanding or compliance of required controls and procedures No record of persons being onsite Lack of awareness of Specific Emergency Procedures and Assembly Points Operators Not Competent to operate Plant Machine and Appropriate Fittings not functioning correctly Tools not fit for use Slips, Trips and Falls Failure to follow site rules Failure to adhere to speed limits and haul road requirements Lack of understanding Traffic Flow Failure to implement Positive Communication Operators Not Competent Failure to follow site rules Failure to adhere to speed limits and haul road requirements Collision of Plant / Vehicles Slips, Trips and Falls Failure to implement a site designated laydown area Sediment builds up in storm water lines Sediment laden water leaving site CONSEQUENCES Persons at risk or not accounted for in the event of an emergency General injuries, Serious Injury or Death Plant Damage Strains, Sprains Hand Injuries, Head Injuries, Eye Injuries, Cuts and abrasions Dehydration and sunburn Crush Injuries Drowning Operator trapped in Plant Environmental Damage All persons entering site (workers, subcontractors, delivery drivers etc) must attend the site office upon arrival and complete the site-specific induction, in accordance with the Induction procedure IMS 02-39 Pre-start / “Kick Off” meeting conducted by foreman to ensure workers are fully aware of the scope of works.

Severed Fingers Consult with all persons involved in the task on the site condition/hazards and job tasks/hazards and their responsibilities. Identify area where the load will be moved too, ensuring there are no obstructions, tripping hazards on route. Where possible use a mechanical aid to lift the object or rearrange the flow of materials to reduce handling. If manual lift must be undertaking, the following considerations must be given: Get a solid hold on the item which you are about to lift, using leg muscles to move low level objects, keeping your back straight by tucking in your chin and bending your knees and lifting with your legs, The load should be held as close to the body as possible. Lift load slowly and do not jerk. Avoid twisting your back during lifting or when moving the load. Lifting with one hand should be avoided. If you are unsure of the load’s weight, ask for assistance Team or dual lifts can be used where practicable. All consideration used in individual lifts need to be applied to team and dual lift tasks. When lifting manhole lids, use lifting aids. The correct Gatic style manhole lifters must be used. Do not lift any load beyond your capability. R1 = E24 If Control Measures are altered R2 rating must be reassessed R2 = L5 Diagram 1 - Manual Handling Techniques ELECTRICAL SAFETY including Tag and Lockout Hazard / Risk Control Measures HAZARDS Untrained worker Procedures not followed Equipment not test and tagged Equipment used without safety switch CONSEQUENCES Serious Injury or Death Electrical shock Burns Fire Any persons working to install, modify, test or certify electrical installations are trained in accordance with both the type of work being undertaken and the jurisdictional requirements. Electrical Safety Procedure IMS-02-04 must be followed Always check to ensure that the electrical equipment being used has been tested and tagged and is in current test date; Ensure all portable electrical equipment is connected to a safety switch; If using a portable safety switch always test that it trips after the equipment is being plugged in by pressing the test button on the side of the safety switch; Specified electrical equipment used in manufacturing work must be protected by a fixed safety switch. Previously a portable safety switch was an option. Never use a double adaptor or piggy back plug or domestic rated power boards in a workshop or construction site; If any electrical leads to portable equipment are frayed, or single insulated coloured cables are showing, do not use the equipment; If personal or hired electrical equipment is to be used at the workplace, the Supervisor needs to approve and visually check it to ensure that it is safe, has been tested and tagged and is in current test date. If electrical equipment is hired, for use in a workplace it is to be: Inspected and tested by a competent person, before every hire and at least within the last 3 months; If the equipment is not working properly or is unsafe, it must be withdrawn from use, with a ‘Danger – Do not Operate’ tag affixed to the equipment. If any electrical equipment is found faulty or does not work: It is to be immediately removed from use It is to be tagged with a ‘Danger – Do Not Operate’ tag; Your supervisor is to be notified immediately; and This tag is only to be removed when this equipment is fixed. Note: The person finding the equipment out of order would be the person to place the tag on the equipment. Always use a portable safety switch connected to a portable generator; if the generator does not have a built-in safety switch. Specialist advice should be sought from an electrician to identify the correct safety protection when using portable generators if unsure Do not touch live welding electrodes unless using insulated gloves. Do not allow any part of welding electrode to touch any part of body; Ensure the welding electrode holders are of an ‘all insulated’ type; and ensure the welding leads are correctly connected and in good condition.

Report any faults / issues Plan the trip - Prior to departure, Operators should review travel route for any hazards, congestion, closures etc. Upon arrival on site the transport / plant operator is required to park the vehicle in an allocated safe parking space, as arranged with the site Foreman Check for OH powerlines and other obstructions above/on ground Always apply park brake prior to leaving vehicle and where required, chock wheels and drums. Loading Loads are to be secured at all times, in accordance with NHVR Load Restraint Guide, where applicable. A load must not be placed in a way that makes the vehicle unstable or unsafe and must be secured, so it is unlikely to fall or dislodge. Load binders, straps, chains and load dogs to be inspected before use, only use certified and tagged equipment Ensure Loads are within maximum Mass and Dimension limits Lowering / Attaching Ramps Gloves must be worn when unlatching, lowering and/or attaching ramps. Fingers kept clear of pinch points around the ramps. If ramps are to be attached, consider using a second person for a team lift. Remember to lift using the legs and bend the knees Inspect ramps to ensure they are in good working condition. All pins used must have a safety clip on the underside to prevent any chance of unplanned vertical movement. VERY IMPORTANT TO CHECK BOTH PINS AND SAFETY CLIPS. Make sure hinges / pins are secure and in good working condition per the manufacturer’s specifications. Ensure machinery weight does not exceed safe working load limit of the ramps. Inspect surrounding area for any debris, uneven ground, steps, gutters or any other hazards that may interfere. Removing Lashing (Tie Downs) Ensure parking brake or other plant isolation is engaged. Remove lashings in sequence (usually front to back). If a lever bar is required, the operator must stand to the side of the bar NEVER directly in line with it. PPE must be worn which may including riggers gloves, eye protection, hard hat and safety boots. Unload Plant Set up exclusion zone around truck/plant being unloaded so all persons are outside the line of fire should plant slip or fall off truck. Access the transport deck via ramps when possible or by other means using 3 points of contact at all times. Extra care must be taken and considered in wet conditions. Clear area of obstructions make sure ground is firm, level, and the area is spacious enough for unloading. Check surrounding environment again immediately prior to starting the plant making sure nothing has changed including pedestrians or other physical obstructions. Use Spotter in a safe place when required. If a spotter is used, clear communication and a clear view of the spotter must be maintained at all times. Raise any part of the plant including attachments off the transport deck enough to not touch the deck whilst moving. When clear and safe to do so, move plant slowly toward the ramps. No slewing, skidding, or skewing whilst moving the plant. Descend the plant down the ramps at a slow and controlled pace with the tracks or wheels positioned in the centre of the ramps Park the plant in the predetermined area within the exclusion zone. Unloading and Reloading equipment / attachments Unloading / loading attachments or other equipment must be carried out with care and attention. Where attachments have an intended purpose of being engaged by a quick hitch this must be used including the safety pin at all times Where required a Spotter is to be used to assist in the engagement of attachments. Clear communication and visibility of the Spotter must be maintained at all times. The operation of the machine whilst carrying out the task must be slow and steady. When using HIAB to unload/load, control measures from lifting SWMS must be followed. Leaving Site Areas left in a clean and tidy state. Sign out and Traffic Management Procedures followed Environmental wash station / gravel driveways utilised.

Changing conditions and operate to suit those conditions overhead power lines, bridges prior to commencing ground personnel, the public and other plant interacting in the area road rules, speed limits, signs and traffic control signals/systems. Loading Positive Communication between driver and excavator / loader operator Is obtained prior to entering the work area and confirmation of preferred load position Ensure TARE weights are not exceeded Ensure nothing protrudes from the body before moving Ensure the area is set up, so the driver drives forward out of load areas and it is not downhill, to prevent rolling back into the excavator/loader. Ensure operators remain in the Cabin while being loaded Ensure operators are aware of plant blind spots Unloading An Exclusion Zone is set up – minimum radius = height of tray + 3m Ensure the driver understands where each load is to be tipped, as this may vary from load to load When setting up Tipping Areas, consideration should be given to ground conditions, load type, angles, ground compaction, & proximity to edges. Drivers should be able to tip up/down a slope not across it. Ensure drivers DO NOT Reverse & Hoist tray at the same time, as this increases the chance of roll over. Ensure all trucks lower hoist before driving off, as failure to do so can increase risk of rollover entanglement & damage to truck Operators must operate within their own ability. If in doubt stop & discuss available options with supervisor and co-workers.

Keep bodily parts away from machinery parts that may crush, vibrate, compact, spin or cut De-energise all stored energies Lock out tags to be placed on equipment before commencing any maintenance works A ‘Danger - Out of Service Tag’ is to be used as a notification to other persons of any extraordinary conditions that may exist, e.g. faulty equipment. Notify supervisor, as the situation warrants. Tags can only be removed by the person who placed the tag. They must satisfy themselves that the equipment or service is in proper working order and that its operation will not cause damage to plant or risk injury to other persons MAINTENANCE OF PLANT Hazard / Risk Control Measures Always open the accumulator’s valve to release pressure. Hoses under pressure act as accumulators. Eliminate all ignition sources or heat sources from contact with hydraulic lines or escaping fluids, sprays or mists resulting from hydraulic failures. All swinging arms, booms, rollers, presses must be lowered or supported to eliminate the risk in the event of a hose failure. If the equipment is mobile, always chock the tires to prevent rolling. When conducting maintenance on hydraulic hoses ensure the hose and coupling manufacturer are the same and that they’re assembled using the manufacturer’s recommended equipment, components and procedures. When connecting threaded or flanged ends, follow proper torque recommendations for hydraulic hoses. Check hydraulic fittings prior to commission Fitter to observe repaired area when operator starts machine Recheck and retighten nuts/bolts Remove lock out tags when repair/Maintenance is complete.

Prior to commencing excavation around live services, a documented risk assessment must be undertaken to confirm adequacy of required controls Project team undertake site inspections to confirm site conditions and underground services using site drawings, DBYD and other visual indicators such as Pits, Valves, Marked Poles and Overhead Power to mark out services. Steps 1-2 is all about planning and making sure all current lives services are identified prior to works taking place, planning works and reconciling DBYD with what is in the ground. No mechanical tools to be used near services, all services must be positively identified using Vacuum Excavation or Hand Digging using Non- Conductive Hand Tools. If any excavation is within 3 meters of services. Blade Buckets must be used when excavating near known services Once the location of live services is confirmed, their location should be clearly marked on the ground using the following method: Pothole markers 100mm PVC pipe inserted into pothole (this prevents earth falling back into the pothole and maintains visibility of the service Conduit with signage indicating type of service & depth Distance between potholes (and markers) should not exceed 5m and be no longer than 3 meters in high risk areas, the distance chosen between potholes must be detailed in Risk Assessment, outlining clearly risk based justification for distance chosen. Fully expose and visually Identify where live services intersect with any planned excavation profile. In such scenarios the service must be fully exposed 500mm either side of the trench at the point of intersection by vacuum excavation or hand digging. Ensure Excavation Permits are issued/understood and signed onto by all relevant workers Follow the Excavation procedure IMS-02-05 Clear area of obstructions, walk over ground to be excavated if required to excavate. Where possible, mark the border of the exclusion zone with suitable hazard markers eg: warning tape, dymark paint or signage No machine work within exclusion zone as per Service Owners relevant guidelines. Barricade open excavations, if left unattended for any period of time and the trench poses a risk to other workers or public. If damage is caused to the service.

No worker to be in the drop zone of the Slew Radius (height divided by 1/2, eg 4m high = drop zone 2m) until the bucket is below chest height of the worker and the plant / excavator is in lift / crane mode. No worker permitted inside the blind spot of any plant (see diagram 7) until positive communication is made with the driver and the plant is in park position and all attachments are lowered and disengaged. Excavation Permit IMS-05-17 must be in place with DBYD and relevant plans attached. The site foreman should be risk assessing permit requirements on a case by case basis. Where working around live services, permit should be opened and closed on a day to day basis. Where working around services that are not live, permits could be opened for a maximum period of one week. When conducting bulk earthworks in Greenfield sites where there are no known services, permits can be valid for the duration of the works. Ladders or stepped access and egress are to be utilised. where people are in trench. The access/egress points must be no further than 9m away. Three points of contact to be maintained during use of ladder Where feasible a trench platform and fixed ladder should be used. Refer to Diagrams Trench Box set up of this SWMS Ladder to be anchored/secured or supported during use and removed during trench shield movement Barricade installed at least 1.5m back from edge of excavation, with “Deep Excavation” Signage. Trenches / Excavations over 900mm deep must be barricaded if unattended Monitor dust levels and suppress using water as required Surrounding water to be monitored for risk of penetrating trench Entry to trench/excavation not permitted, until shoring or benching is installed Trenches may need to be battered, benched or shored depending on ground conditions.

Take care when securing load and ensure correct PPE is worn Ensure all chains, slings, and lifting aids are designed to take the weight of the load, tested and in date, and free from defects Plant is only to be operated by persons holding appropriate qualifications and VOC. Before reversing, the operator is responsible for ensuring that no person/ workers are in close proximity to the vehicle. Appropriate work areas are to be set up where there is the chance of unauthorised persons entering the work area. Exclusion zones with ‘No Entry’ signs are to be used. These zones are to be co-ordinated with site management. Do not walk behind machinery that is being operated Use a spotter to ensure an exclusion zone of at least the length of the boom swing, is kept around operating plant where necessary All lifting and lowering of loads only to be done whilst machine is stationary, or loads are to be carried at a low level with all workers outside the exclusion zone. When attaching chains/slings to an excavator in crane mode, the excavator operator must disengage the drive lever prior to the task being undertaken CRANE OPERATIONS Hazard / Risk Control Measures Get spotters/operators attention before entering work / exclusion zone. Do not enter work/exclusion zone of operating plant without operator permission. Heavy formwork to be lifted by excavator (anti hose burst protection must be fitted to excavator used in crane mode). De-energise all stored energies Mechanical motion can be dangerous. Watch out for swinging arms, booms, rollers, presses — anything that moves can be dangerous if a hose fails. For example, when a hose bursts, objects supported by fluid pressure may fall, and vehicles or machines may lose their brakes. If the equipment is mobile, always chock the tires to prevent rolling. The load should be checked to ensure sufficient clearance if the load should shift. Position of the crane for lifting to ensure that sufficient area is provided for outriggers or stabilisers to be adequately extended and packed, If you are unsure of the condition of the ground, a geo-tech certificate must be obtained to ensure safe operation of the crane/excavator/HiAb, prior to the lift being commenced, If the crane/excavator/HiAb is to be set-up on a suspended slab, an engineer’s certificate must be obtained to ensure that the total weight of the crane/excavator/HiAb, the load and any lifting gear employed can be supported, or that sufficient support will be provided to ensure safe operation, prior to the lift being commenced, The size of the load must be combined with the height to be lifted and the radius to ensure that the load will not become “boom-proud”. When outriggers are out of sight, the operator will ensure that a lookout or observer will keep people away when retracting the outriggers, Once the crane/excavator/HiAb is secured, the operator will remove all equipment put in place for the control of traffic and pedestrians, and then move the crane/excavator/HiAb to a safe area.

Where electrical hazards exist, the ladder used must be made of non-conductive material i.e.; timber. Three (3) points of contact must be maintained at all times whilst on the ladder -.i.e. 1 foot and 2 hands or 2 feet and 1 hand Implement exclusion zones, hazard markers, signs, equipment, emergency response equipment & PPE Signs will adequately indicate to the members of the public; The nature of the workplace, that unauthorised entry to the workplace is not allowed and the direction the pedestrians or traffic is to move. Be aware of persons, plant, equipment, buildings & weather conditions and take necessary precautions. Edge Protection including handrail/ kick boards to be used as required. Fall restraint System and Fall Arrest System to be used as required Use an Elevated Work Platform (EWP) to gain access if necessary. When working at height on plant – Will have suitable means of access/egress. Where tools may fall, a tool lanyard will be used. Isolation procedures to be implemented if required. All servicing to be carried out by competent person. Lower all attachments to ground. Ladders are generally used for access above ground level or to gain access to a difficult work area. Equipment used for the purpose for which it was designed. Is no longer than 6.1m (single ladder) or 9.2m extension ladder used to do electrical work, or 7.5m for other extension ladders Use a ladder that is suitable for job and conforms to AS/NZS 1892. Is not used to support a weight greater than that for which it was designed. WORKING AT HEIGHTS – Above 2m Hazard / Risk Control Measures Ladders that are damaged are to be taken out of service and labelled with a ‘Danger – Out of Service’ tag. Use an Industrial type ladder with a load rated not less than 120kg Step ladders are only to be used in the fully open position. When on a ladder the user must be facing the ladder at all times. Any tools or equipment to be carried up the ladder must be in a backpack, tool belt or other means to ensure that the user’s hands remain free. A second person shall foot the ladder whilst in use. The ladder must be positioned at a slope of 4 in 1 (for every metre in height the base of the ladder should be set back 250 mm). Where tools may fall from height a tool lanyard will be used. Tools, plant and equipment used at height will be kept at a minimum. Tools /equipment will not be left where they can be knocked or fall over edge. No more than one person shall be on a ladder at any time. R1 = E24 If Control Measures are altered R2 rating must be reassessed R2 = L5 CONFINED SPACE Hazard / Risk Control Measures HAZARDS Gas detector not operated correctly fire and explosion No person presents to help injured person or respond to emergency flammable atmospheres Non-compliant with legislative requirements No awareness of confined space works being undertaken, incorrect controls not in place work area not adequately isolated Worker or Unauthorised person entering confined space risk of engulfment Asphyxiation Respiratory protection not working Harness breaking No awareness of any issues for persons in confined space heat, Persons left in confined space Members of public access confined space Confined space left open Incorrect Techniques being used CONSEQUENCES Serious injury or death Burns Asphyxiation Heat stroke/stress, exhaustion Confined Space Procedure IMS-02-02 must be followed All work is to be planned and supervised Any staff that enters or may be required to enter a confined space must be trained in working in a confined space and must never enter a confined space prior to obtaining written authority (Confined Space Entry Permit – IMS-05-05). Use direct reading gas detectors to test atmosphere of confined space. Gas detector must be operated by a competent person, calibrated and maintained. Helmets with Straps must be worn to avoid helmets falling Tools must have lanyard attached or placed into suitable bucket for the task. All tools and equipment to be left 1m back from confined space if there is a risk from falls from height Initial testing should be done from outside the confined space by inserting a sample probe and/or portable gas detection device at appropriately selected access holes, nozzles and openings. Because contaminants can settle at different levels, each part of the confined space should be tested – side to side and top to bottom Atmospheric testing and monitoring shall be carried out consistent with the hazards identified and the findings of the risk assessment. No person is to work in a confined space without a spotter Ensure personnel and equipment are available to execute a rescue where control measures cannot otherwise ensure that: A record of each person within a confined space and each person required for stand-by purposes should be maintained. The written authority should be displayed in a prominent place, preferably adjacent to the confined space, to facilitate signing and clearance. Appropriate emergency response and first aid procedures and provisions shall be planned, established and rehearsed. Where possible the confined space should be isolated — withdrawn from service. Where not possible workers must be protected from engulfment or introduced hazardous atmospheres. Ensure the confined space has been purged and/or cleaned Ensure the area has been signposted and barricaded to prevent unauthorised entry The equipment shall be appropriate to the work being conducted and the specific confined space. All employees, inside and outside of the confined space, will be trained in the use of all the safety equipment. Respiratory protection devices must comply with AS/NZS 1716 and/or 1715. Where safety harnesses and lines are required, they must comply with AS/NZS 1891.1 If found necessary ventilation will be provided to the confined space prior to entry and during occupancy. Ventilation should be by natural, forced or mechanical means to establish and maintain a safe atmosphere. Any contaminants removed from the confined space should only be exhausted to the atmosphere at a location where they do not represent a risk. CONFINED SPACE Hazard / Risk Control Measures Where flammable atmospheres exist eliminate all sources of ignition. Hot work is not permitted to commence in a confined space until a hot work permit has been issued and until the atmosphere has been purged and no longer presents a hazard to personnel. Fans used to exhaust flammable contaminants should be intrinsically safe. Where necessary, reference should be made to AS/NZS 1020 to guard against static electricity discharge. Communication and where possible, observation should be maintained between those in the confined space and the stand-by person. This can be achieved by voice, radio, hand signals, hard wired communications or other appropriate means. In confined spaces where flammable conditions could exist, radios should be intrinsically safe. Electrical equipment where used in a confined space and connected to an external supply should comply with AS/NZS 3100 and where required, installed in accordance with AS/NZS 3000. Portable electrical equipment should be connected to an earth-free, protected extra-low voltage supply from an isolating transformer (AS/NZS 3108) which is located outside the confined space. Protected through RCD (AS 3190) located external confined space. Must be intrinsically safe where there is a potential for combustibles. The use of hazardous substances in a confined space should be avoided wherever possible. If the substance must be used, the area must be well ventilated at all times and PPE worn in accordance to that specified on the MSDS. Personnel must be familiar with the product prior to using it in a confined space and a copy of the MSDS for the product must be readily available when and where it is being used. Dependant on the work being undertaken in the confined space and the conditions within the confined space, the workers should be monitored to prevent over exertion and/or collapse from fatigue. This can also be achieved by job rotation. Entry and re-entry to any confined space must only be allowed after the completion of all required documentation. Re-entry to the confined space is to be treated in the same manner as the initial entry. It is to be acknowledged in writing that work in the confined space has been completed and that all persons involved in the work have left the space before authorisation for the return to service of the confined space is made. Closure of entry to confined space as appropriate.
