LPG Forklift Operations SWMS
LPG-powered counterbalance forklift operations — LPG cylinder changeover, connection-integrity check, indoor ventilation, CO monitoring, hot-work exclusion, emergency LPG leak response in warehouse and distribution settings.
SWMS variants reference your state’s WHS legislation. Instant download after payment.
LPG-powered counterbalance forklift operations combine the mechanical hazards of powered mobile plant with the hazardous-chemical risks of liquefied petroleum gas storage, decanting and combustion. Operators routinely change 18kg or 210kg LPG cylinders, verify POL fitting integrity, work in partially enclosed warehouses where carbon monoxide and unburnt LPG can accumulate, and operate near racking, pedestrians and ignition sources. Under WHS Regulation 2025 Chapter 4 Part 4.5 (Plant) and Part 7.1 (Hazardous Chemicals), the PCBU must document a Safe Work Method Statement before the task commences because the work is High-Risk Construction/Operational Work involving powered mobile plant and a Schedule 11 hazardous chemical (LPG, UN 1075). A SWMS is mandatory, must be developed in consultation with workers holding an LF high-risk work licence, and must be available for inspection by WHS regulators and reviewed after any incident, near-miss or change in plant or fuel supplier.

Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Where feasible, replace LPG forklifts with electric counterbalance units in fully enclosed warehouses to eliminate combustion emissions and stored flammable gas at the work face.
- 2Elimination — Remove all ignition sources, hot work permits and smoking areas from the LPG cylinder storage and changeover zone in accordance with AS 1596 Section 5 separation distances.
- 3Substitution — Substitute manual 18kg cylinder swaps with quick-connect dry-break couplings and cylinder cages on wheeled trolleys to reduce drop risk and POL fitting wear.
- 4Engineering — Install fixed CO monitors with audible/visual alarms at 30 ppm and forced mechanical ventilation delivering minimum air changes per AS 1668.2 in all indoor LPG forklift operating areas.
- 5Engineering — Fit forklifts with operator restraint systems, blue spotlights, reversing alarms, speed limiters set to 10 km/h indoors, and seatbelt interlocks per AS 2359.2.
- 6Engineering — Provide bunded, ventilated, signposted external LPG cylinder storage cage with fire-rated separation from buildings and ignition sources per AS 1596 Table 2.1.
- 7Administrative — Verify operator holds current LF high-risk work licence, conduct documented pre-start checklist each shift, and apply leak-test solution to POL connection after every cylinder changeover.
- 8Administrative — Enforce segregated pedestrian walkways, give-way protocols, exclusion zones during cylinder changeover, and traffic management plan reviewed under WHS Reg s215.
- 9PPE — Issue leather rigger gloves rated for cryogenic contact, safety glasses to AS/NZS 1337.1, steel-cap boots to AS/NZS 2210.3, and hi-vis vest to AS/NZS 4602.1 for cylinder handling.
- 10PPE — Provide personal CO monitors to AS/NZS 60079 for operators in enclosed areas and flame-resistant coveralls to AS/NZS 4824 for personnel performing LPG cylinder changeovers.
Applicable Codes of Practice
Sets cylinder storage separation distances, ventilation, signage and exclusion zones directly governing on-site LPG cylinder cages and changeover areas.
Defines operator competency, pre-start inspection, load handling, speed limits and pedestrian segregation duties applied during every forklift shift.
Triggers PCBU duty under WHS Reg s203–214 to identify plant hazards, implement controls and maintain inspection records for forklifts.
Applies WHS Reg Part 7.1 obligations for LPG manifest, SDS access, placarding, ignition source control and emergency planning at the workplace.
High-Risk Construction Work triggered
On a construction site the counterbalance forklift is powered mobile plant moving through shared pedestrian and work areas. In a warehouse or distribution centre the same work is not construction work, and the plant, hazardous chemical and LF licence duties apply on their own.
PCBU must consult workers, retain SWMS for two years after work ceases or until incident investigation closes, and produce on regulator request; penalties are substantial and indexed, with the current maximum following the prevailing WHS schedule.

Worked example
At a regional fast-moving consumer goods distribution centre, a shift supervisor runs the 6:00am pre-start brief for four LPG forklift operators rostered to load outbound pallets. The supervisor opens the LPG Forklift Operations SWMS on the toolbox tablet and walks the crew through the seven hazard lines. When operator three flags that yesterday's CO monitor alarmed briefly in the despatch bay, the supervisor cross-references the engineering control requiring AS 1668.2 ventilation and immediately tasks maintenance to verify the roller-door exhaust fan before any LPG units enter that zone. The crew then reviews the cylinder changeover sequence: trolley use, POL fitting leak-test with soapy solution, and the 3-metre ignition exclusion zone per AS 1596. Each operator confirms their LF licence is current, signs the SWMS sign-on register, and clips on a personal CO monitor. Mid-shift, a pedestrian contractor enters the loading aisle without hi-vis; operator two stops the truck, isolates the park brake, and the supervisor returns to the SWMS administrative control on traffic management, escalating to a documented site-rule reinforcement and updating the SWMS review log. At end of shift the SWMS is filed with the day's amendments noted, ready for the next pre-start and available for any WHS inspector request.

Frequently asked questions
Is LPG forklift work high risk construction work?
Not in a warehouse. Distribution centre and manufacturing forklift work is not construction work, so the s291 categories and the s299 SWMS duty do not apply there. What does apply is Chapter 4 Part 4.5 for plant, Part 7.1 for hazardous chemicals covering LPG as UN 1075, and the LF high risk work licence, which the operator must hold regardless of site type. Where a forklift works on a construction site, construction work in an area with movement of powered mobile plant is high risk construction work under s291(o) and s299 then requires the SWMS. Many principals and landlords also require one contractually.
Can we run LPG forklifts inside an enclosed warehouse?
Only with ventilation and monitoring you can evidence. Incomplete LPG combustion produces carbon monoxide, which builds up in enclosed or partially enclosed spaces and causes loss of consciousness before most people register a symptom. The controls require fixed CO monitors alarming at 30 ppm, mechanical ventilation to AS 1668.2 across all indoor LPG operating areas, and personal CO monitors for operators working enclosed. Sitting above those is the elimination control — electric counterbalance units in fully enclosed warehouses remove both the combustion emissions and the stored flammable gas. The worked example turns on this exact issue, with a despatch bay alarm holding LPG units out until the exhaust fan is verified.
What does a compliant cylinder changeover look like?
Trolley, leak test, exclusion zone. Cylinders move in a cage on a wheeled trolley rather than being carried, so a dropped 18 kg or 210 kg cylinder cannot shear its valve and vent. After every changeover the POL connection is leak-tested with solution rather than by smell, because odourant fade means slow seepage goes undetected. A three-metre ignition exclusion zone applies during changeover with no hot work, smoking or static sources inside it, and the storage cage is sited to the separation distances in AS 1596. Quick-connect dry-break couplings are the substitution control where manual swaps can be designed out of the task altogether.
How does the SWMS handle pedestrians in shared aisles?
Separation first, behaviour second. Segregated walkways, give-way protocols at blind corners and loading-dock zones, and a traffic management plan reviewed under the plant provisions are the primary controls. On the machine, blue spotlights, reversing alarms, visibility aids and speed limiters set to 10 km/h indoors reduce what is left. Operator restraint and seatbelt interlocks to AS 2359.2 address the other fatality mechanism entirely — a tip-over kills the operator who tries to jump clear rather than stay in the seat. The worked example runs the pedestrian control live, with a contractor entering an aisle without hi-vis and the truck stopped before the site rule is reinforced.
What do I receive, and what needs adding before our operators sign on?
A single editable Word document, bought once, containing the hazard register and risk ratings shown here, hierarchy-of-control mapping, a state-specific WHS legislation schedule, a worker sign-on register, a pre-start checklist and an incident escalation flow. Site detail goes in first: fleet make and model, cylinder size and your gas supplier, the storage cage location and its separation distances, ventilation and CO monitor commissioning and alarm setpoints, your site traffic management plan and pedestrian layout, and each operator's LF licence number and expiry. It supports your plant risk assessment and chemical register rather than standing in for either.
