WHS Management for Heavy Engineering Fabrication

Large-scale fabrication of pressure vessels, mining equipment, and structural assemblies demands rigorous WHS controls.

Heavy engineering fabrication produces large-scale welded assemblies including pressure vessels, mining equipment, bridge components, and industrial plant. Workers perform sustained welding operations on thick-section steel, often in semi-confined positions inside vessels and large assemblies where fume concentrations are highest. Overhead crane operations are frequent and involve loads weighing multiple tonnes. The combination of high welding fume exposure, crane hazards, confined space entry, and heavy manual handling creates a risk profile that requires comprehensive WHS management and dedicated occupational hygiene programs.

Key Hazards

Sustained welding fume exposure in semi-confined positionsOverhead crane load drop and crush hazards with multi-tonne loadsConfined space entry for internal welding and inspectionNoise exposure from gouging, grinding, and impact operationsBurns from preheating and post-weld heat treatment processesManual handling of heavy components during fit-up
