What this pack is
Mixed steel and aluminium work, elevated work on decks and chassis, and high-deposition framing.
Each industry here is a complete risk assessment for one kind of workshop, with the hazards and their starting ratings already identified by a Certified Industrial Hygienist. You answer Yes, No or N/A to the controls, and the calculator works out your residual risk, builds the Action Plan and produces the finished report.

The most serious hazards in truck body and trailer
A sample of the 57 hazards in this assessment, each shown with its consequence and the starting risk rating given by a Certified Industrial Hygienist before any controls are counted. The controls themselves are in the calculator.
Crush injury and fatality from a body or tailgate coming down. Hydraulics leak down, and a hose or seal that has held all morning can fail in a second. Gas struts and springs release with enough force to kill. Safety · inherent risk 5B.
Fuel tank or vapour ignition, air reservoir failure, tyre fire, electrical fire in the loom, and arcing through the vehicle earth path damaging electronics and injuring the welder. A fire in a vehicle in a workshop spreads to the building quickly. Process Safety · inherent risk 5B.
A mixture of fine aluminium and iron oxide is a thermite mixture, which once ignited burns at a temperature no extinguisher will control and reacts with water. Fine aluminium is also combustible in suspension and releases hydrogen when wet. Process Safety · inherent risk 5B.
Zinc fume (metal fume fever), lead from old paint (a lead process with notification and biological monitoring duties), chromate primers containing Cr(VI), cadmium from plating, isocyanates from two-pack coatings. None of these are controlled by the arrangements in a bare mild steel workshop. Occupational Hygiene · inherent risk 4C.
Welding fumes are classified IARC Group 1 (carcinogenic to humans, lung cancer, with limited evidence for kidney cancer). Also occupational asthma, chronic bronchitis and reduced lung function. The exposure standard for welding fumes (not otherwise classified) is 1 mg/m3 as an 8-hour time weighted average, and this figure carries through into the Workplace Exposure Limits that apply from 1 December 2026. Occupational Hygiene · inherent risk 4C.
Chronic manganese exposure causes irreversible neurological injury: tremor, rigidity, impaired balance, cognitive and mood change, resembling parkinsonism. From 1 December 2026 the workplace exposure limit falls from 1 mg/m3 to 0.1 mg/m3 inhalable and 0.02 mg/m3 respirable, a tenfold and fiftyfold tightening. Manganese typically makes up several per cent of mild steel welding fume by mass, so a workshop sitting on the 1 mg/m3 total fume limit can already be at or above the manganese limits. Manganese is normally the first limit a mild steel workshop exceeds, and it is exceeded well before total fume becomes a problem. Occupational Hygiene · inherent risk 4C.
Crush injuries, multiple fractures, fatality. Vehicle and mobile plant incidents are consistently among the leading mechanisms of work-related fatality in Australia. Safety · inherent risk 4C.
Load dropped onto a person: crush injuries, multiple fractures, fatality. Sling angle is the most common miscalculation, because working load limit falls sharply as the included angle opens up. Safety · inherent risk 4C.
How one hazard is rated
Hazard S1.1 — manual handling of sections, plate and offcuts — starts at 2D, rated before any controls are counted. The calculator lists 8 controls for it, from elimination and extraction at the source down to PPE, monitoring and emergency arrangements. You answer Yes, No or N/A for each on the floor. Once the last one is answered it works out the control score, applies any severity reduction earned by physical controls, and shows the residual risk as RED, YELLOW or GREEN. Every control you answered No to goes into your Action Plan, most urgent and most effective first, ready for a responsible person and a due date.
Steel, aluminium and a vehicle that is still live
A truck body and trailer shop welds framing at high deposition rates, on steel and aluminium side by side, often on or under a chassis that still has its fuel tank, air reservoirs, batteries and loom fitted. The air carries welding fume, classified IARC Group 1, with an exposure standard for welding fumes not otherwise classified of 1 mg/m3 as an 8-hour time weighted average. Manganese from mild steel framing is the limit most likely to be exceeded first, and it tightens sharply from 1 December 2026.
Two hazards carry the liability that sets this trade apart. The first is stored energy: tipper bodies, tailgates and lift platforms held up by their own hydraulics, air suspension still charged, gas struts and springs under load. A hose that has held all morning can fail in a second. The second is the grinding dust. Fine aluminium collecting in the same extractor as iron oxide from steel grinding is a thermite mixture, which once lit burns hotter than any extinguisher can control and reacts with water.
A general steel fabricator next door has neither problem. Their work leaves the shop as a structure; yours leaves as a vehicle, and it is built with the vehicle's own systems in place.
What an inspector checks in a body building shop
The assessment puts the underside of the vehicle first. Before anyone goes underneath a raised body or tailgate, are rated mechanical props, stands or safety bars fitted and engaged, never the hydraulics alone? Is the hydraulic system depressurised and accumulators discharged, verified at a gauge? Is air suspension exhausted with the chassis on rated stands, gas struts and springs released under a documented procedure, and isolation applied by the person doing the work with their own lock and tag? Each of these is a gate.
Next come hot work on the chassis and the extraction. The calculator asks whether fuel, air and electrical systems are dealt with before rails are cut or welded, and whether aluminium and steel grinding are kept apart in separate extraction. It also covers the shop plant: guards on the bandsaw, cut-off saw, pedestal drill, linisher and pedestal grinder, emergency stops to AS/NZS 4024, work rests to AS/NZS 1788, and lifting gear inspected to AS 3775, AS 4497 and AS 2741.
What your first walkthrough tends to reveal
Body builders usually answer Yes on welding gear and No on the vehicle interface. Tipper bodies are propped with the ram. The battery stays connected because disconnecting it resets the vehicle systems. Sparks fall onto tyres and airlines at the rail. And the shop has one dust collector serving every grinder, whether the job that day is an aluminium tray or a steel chassis extension.
Green on the handling hazards comes from top-tier answers such as physical barriers or bollards between walkways and the forklift route where finished bodies are loaded out, stock delivered in pack weights the shop can move mechanically, and cranes or vacuum lifters for anything above the site manual handling limit. For grinding, a fixed cut-off saw in place of a hand-held grinder for straight cuts reduces both the wheel hazard and the dust.
NOT RATED here looks like a fitter under a tipper body with the hydraulics holding it. If you answer No to rated props or safety bars engaged before anyone goes underneath, the stored energy hazard is not scored, whatever else you have in place. The report shows it as NOT RATED and lists the prop as the first item in the Action Plan.

This is a generic risk assessment for a typical workshop of this kind, to support your due diligence — completing it is not compliance in itself. You must answer it for your own site, consult your workers, put the missing controls in place, and get competent advice where it says so — exposure monitoring, for example, is work for an occupational hygienist. The limits are set out at the front of every report.
