EWP

• Scissor lift. A platform raised vertically on a folding scissor mechanism. Common for ceilings, services and fit-out on level slabs.

• Boom lift. A platform on a telescopic or articulating boom that can reach up and out over obstacles. Used for facades, steel erection and work over plant or voids.

• Vertical lift. A compact mast-type platform for one person, used in tight internal spaces.

• Truck-mounted EWP. A boom on a truck, often called a cherry picker, used for street works and short visits.

• Spider or tracked lift. A lightweight boom on tracks with outriggers, used where access or floor loading is limited.

Under the model WHS Regulations, operating a boom-type elevating work platform where the boom length is 11 metres or more is high risk work. The operator needs a WP class high risk work licence, issued by the state or territory work health and safety regulator after training and assessment.

The 11 metre threshold is based on boom length, not working height. Scissor lifts, vertical lifts and boom-type EWPs under 11 metres do not need a high risk work licence. The operator must still be trained and competent for the specific machine. Many sites and principal contractors ask for evidence of EWP training, such as an industry operator card, plus a familiarisation on the model being used.

Victoria regulates this under its own Occupational Health and Safety Regulations, but the licensing requirement for boom-type EWPs is broadly aligned. Check the current rules with your state regulator.

EWP incidents usually come from overturning, crushing between the platform and a fixed structure, falls from the basket, and contact with powerlines. Controls normally include:

• Pre-start inspection. Check controls, emergency lowering, tyres, outriggers, guardrails and logbook before each shift.

• Ground conditions. Check the ground or slab can take the load, and keep clear of edges, pits and penetrations.

• Fall protection. Boom lifts usually require a harness attached to the anchor point in the basket. Follow the manufacturer's instructions.

• Crush protection. Secondary guarding and a trained ground person for rescue are increasingly expected for boom lifts.

• Exclusion zones. Barricade below the work and keep clear of overhead powerlines by the distances your state requires.

• Rescue plan. Someone on the ground must know how to lower the platform using the ground controls.

• Confusing working height with boom length. The WP licence threshold is boom length, not how high the platform goes.

• Using the EWP as a crane or a way to exit at height. Unless the manufacturer allows it, the basket is not for lifting loads or getting off onto structures.

• Skipping familiarisation. Licensed operators still need to know the controls of the specific model.

• No ground rescue plan. If the operator is trapped or injured, someone must be able to bring them down quickly.
