WAH — Scissor Lift Operations SWMS

This SWMS covers electric and diesel scissor lift operations on construction sites, warehouse fit-out, maintenance work, and commercial interior projects — pre-start machine check, ground assessment, platform operation, and post-shift lock-off. It is scoped for competent scissor-lift operators, their spotter or dogman when travelling under load, and the Principal Contractor personnel who authorise the plant for use on the site. Scissor lifts are frequently treated as interchangeable with boom lifts, but the hazard profile is distinct. A scissor lift is a vertical-only platform with a large footprint and no out-of-balance moment — it does not catapult, it does not swing, and the operator is contained within a guardrailed platform. Its failure modes are tip-over from slope or pothole, overhead crush against a fixed structure, and electrocution from unintended contact with overhead services. These are different from the boom-lift failure modes of catapult ejection and pendulum swing. The SWMS addresses scissor-specific controls and is not interchangeable with the boom-lift document. All work above 2 m triggers HRCW Category 3; operation of powered mobile plant triggers Category 13. Section 299 of the WHS Regulation 2025 requires this SWMS. CIH-authored against the current regulatory baseline and aligned with AS 1418.10 for EWPs and AS 2550.10 for EWP safe use.

Control measures

Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.

1. 1Pre-start inspection per AS 2550.10 before each shift — check platform guardrail integrity, control functions, emergency lower, ground-fault indicator, battery level (electric) or fuel level (diesel), wheel condition, outrigger or stabiliser function, and load-sensor calibration. Pre-start sheet signed and filed.
2. 2Ground assessment before placement — confirm the ground gradient is within the manufacturer's slope limit (typically 1.5° for slab scissor, 3° for rough-terrain); probe for soft ground, recent fill, or underground voids; confirm ground bearing supports the scissor lift gross weight (often 2.5-5 tonnes).
3. 3Overhead clearance survey before platform elevation — map overhead power lines, ducts, beams, and ceiling features; establish a minimum 3 m exclusion from LV lines and 6.4 m from transmission per SafeWork NSW guidance; where overhead structures are within 600 mm of the travel path, a spotter is assigned.
4. 4Operator competency — formal familiarisation training on the specific machine model (controls vary between manufacturers); the operator demonstrates the emergency-lower function to a supervisor before first use. No HRWL is required for scissor lifts; a WP-class HRWL applies only to boom lifts with boom length ≥ 11 m.
5. 5Platform gate closed and latched before elevation; lanyard is optional on a scissor lift (guardrails provide primary fall protection) but where the manufacturer specifies harness use, an AS/NZS 1891.1 harness with lanyard to the platform anchor is worn.
6. 6Operator remains inside the platform at all times during elevation — no climbing onto the guardrail, no exit at height, no leaning out to reach beyond the platform footprint.
7. 7SWL observance — total of operator(s), tools, and materials on the platform does not exceed the manufacturer SWL marked on the platform; the SWL applies at any elevation including retracted.
8. 8Travel-at-height restrictions — scissor lifts are generally not designed for travel above the manufacturer-rated elevation on soft or uneven ground (typically 2-3 m on slab, restricted to retracted position on rough terrain); operator checks the machine-specific manual and follows the travel limits.
9. 9Ground-level spotter for any travel within 2 m of pedestrians or other plant; the spotter maintains line of sight and a radio channel with the operator.
10. 10Charging regime — charging at an appropriate voltage supply with RCD protection; charging lead routed out of pedestrian and vehicle paths; battery-room ventilation where applicable per the Code of Practice: Managing Risks of Hazardous Chemicals (lead-acid off-gassing).
11. 11Overhead power line de-energisation via the network operator where the EWP work path cannot maintain the required approach distance; temporary line-drop or insulated line cover installed before work commences.
12. 12PPE baseline: safety footwear (AS/NZS 2210.3), high-visibility long-sleeve shirt, hard hat with chin strap (AS/NZS 1801), Grade II eyewear (AS/NZS 1337.1), and cut-resistant gloves where hand-tools are used on the platform.
13. 13Post-shift lock-off — scissor lift parked on level ground, platform fully retracted, ignition keys removed and stored with the site supervisor, battery isolator opened, charging lead connected if required.
14. 14Daily pre-start toolbox talk covering ground conditions, overhead clearance changes, weather, and any machine fault found in the shift prior; worker sign-on register records operator and spotter.

Worked example

A two-person crew — one scissor-lift operator and one ground-level spotter — is engaged for 3 days of light-fitting replacement in a warehouse in Eastern Creek. The lift is a 10 m slab scissor, SWL 230 kg. Before work commences the operator completes this SWMS: a pre-start inspection identifies a slow descent rate on lower-control — the machine is tagged out and the hire company replaces it; the replacement lift's ground-level check confirms slab gradient below 1° throughout the work area; all overhead fluorescent luminaires are mapped with a minimum 500 mm clearance identified; the operator demonstrates emergency lower to the site supervisor. Work proceeds over 3 days with 94 fitting change-outs; on day 2 a pallet-laden forklift crosses the work area — the spotter halts the scissor lift travel and radios the forklift operator. No incident.
