Part four - plant siting and setup Unloading the EWP If the EWP is unloaded from a truck, are there measures in place to prevent people being hit or crushed by the EWP during the unloading process: This includes: preventing access of people to the unloading area ensuring the boom is lowered ensuring the truck is on firm, level ground with no side slope using a winch with the required capacity. Note: When loading and unloading EWP’s on tilt trays the truck winch should be attached at all times (refer WHSQ Alert: Safe loading of elevated work platforms on tilt tray trucks 2009). Yes No N/A Comments: Proximity to plant, structures and public areas Is the EWP positioned so that the risk of injury from workers in the working platform being trapped, crushed or otherwise injured is minimised? Consider: overhead electrical lines and other services overhead structures other plant (e.g. EWPs, mobile cranes) temporary installations (e.g. scaffold, formwork). Yes No Comments: Ground conditions Have ground factors been considered that will affect the ability of the ground to provide adequate support? This will consider, but not be limited to: the type of ground (e.g. clay, sand, rock or a mixture of these) whether the ground has been backfilled the presence of water location of excavations, embankments or underground services continued operation of the EWP in one location non weight bearing structures (pits, manholes) elevated/suspended floors. Yes No Comments: Is certification available from a competent person (e.g. geotechnical engineer for support on ground, structural engineer for structures, marine surveyor for vessels) that the surface has adequate bearing capacity and/or stability to support the EWP in the following situations: near an excavation or embankment when working on a slope and the manufacturer’s specifications are not known on building structures or suspended slabs on floating vessels (e.g. barges, pontoons) where the bearing capacity of the ground is not known and there are indications that the ground may be made up of fill (e.g. presence of rubble) where there is doubt about the safety of any particular siting? Note: the maximum wheel and/or outrigger loads are specified in the operators manual and marked on the EWP. Yes No N/A Comments:
Access / egress from the EWP at height If workers are leaving or entering the platform whilst elevated, is the risk of a fall being adequately managed? This includes: considering whether a safer method of access is available the working envelope of the EWP is adequate to access the landing area the work platform is adequately positioned in relation to the landing area the risk of falling from the landing area is managed there is a tag out system on the base controls of the EWP. Yes No N/A Comments: Fall arrest systems If the unit is a boom type EWP, are all occupants wearing a travel restraint or fall arrest harness? This includes: harness and lanyard in good condition lanyard length suitable for EWP size and work activity lanyard attached to appropriate anchorage point energy absorption device in lanyard workers have been trained in the use of harnesses Note: shorter 1.2 metre lanyards should be used on smaller platforms with top attachment points (refer: EWPA Policy on the use of fall arrest systems in elevating work platforms - ) Yes No N/A Comments: Managing the risk of falling objects Are control measures in place to minimise the risk of workers or other people being hit by falling objects when the EWP is in an elevated position? These control measures include: tool lanyards mesh screens scheduling work tasks. Note: Mesh screens must only be installed with the approval of the EWP manufacturer or a competent person. Yes No Comments: Operating the EWP Are all workers standing on the floor of the EWP and any materials kept within the guardrails? Yes No Comments: Does the total mass of the personnel, materials and tools inside the platform remain within the rated capacity and allowed single point loadings of the EWP? Yes No Comments: Leaving the EWP unattended Before leaving the EWP unattended, has it been secured to prevent unauthorised use? This includes: positioning the EWP in a designated area disabling all powered motions removing keys. Yes No Comments:
