WHS Management for Plastics & Rubber Manufacturing

Styrene drops 60 per cent and isocyanates drop 75 per cent under incoming WELs. Your ventilation and monitoring must be ready.

Plastics and rubber manufacturing encompasses injection moulding, extrusion, blow moulding, thermoforming, fibreglass layup, and rubber compounding operations. Workers face chemical exposure to styrene in fibreglass and composite manufacturing, isocyanates in foam production, plasticiser fumes during PVC processing, and thermal degradation products from overheated polymers. Machine entrapment in injection moulding presses, extruders, and rubber mills is a serious hazard. The incoming WEL reductions for styrene and isocyanates will require significant upgrades to ventilation and exposure monitoring programs across the sector.

Key Hazards
