Waste Compactor Operation SWMS

Waste compactors and balers in warehousing facilities present severe entrapment and crush hazards that have resulted in multiple fatalities across Australian workplaces. Workers can become trapped in the compaction chamber during loading, cleaning, or jam clearing if safety interlocks are defeated or bypassed. The compaction forces generated by these machines are sufficient to cause fatal crush injuries in seconds. The WHS Regulation 2025 strengthens requirements for plant guarding, interlock systems, and lockout-tagout procedures that directly apply to compactors and balers. This SWMS template covers compactor and baler operation, loading, and maintenance with controls mapped to the Managing Risks of Plant code.

Legal Requirements

regulation

WHS Regulation 2025 Part 5.2 — Plant

hrcw category

Work involving powered mobile plant (severe crush and entrapment risk)

code of practice

Managing Risks of Plant in the Workplace (binding July 2026 under Section 26A)

section 26a binding

Yes — Plant code binding July 2026. Non-compliance is admissible as evidence of breach.

Hazards

Hazard	Consequence	Likelihood
Entrapment in compaction chamber during loading or jam clearing	Fatal crush injuries	Unlikely
Crush between compactor ram and chamber walls during operation	Fatal crush injuries, amputation	Unlikely
Hydraulic system failure causing uncontrolled ram movement	Crush injuries, hydraulic injection injuries	Unlikely
Biological exposure from handling contaminated waste materials	Infection, needle stick injuries, respiratory illness	Possible
Manual handling injuries from loading heavy or awkward waste items	Musculoskeletal injuries, back strain	Likely

Controls (Hierarchy of Controls)

Maintain all compactor guard interlocks — zero tolerance for operation with interlocks defeated or bypassed

Implement lockout-tagout before any entry into the compaction chamber for cleaning or jam clearing

Install and maintain light curtains or presence-sensing devices at the compactor feed opening

Restrict compactor operation to trained operators with documented verification of competency

Provide PPE including puncture-resistant gloves, safety boots, and eye protection for waste handling

Conduct quarterly interlock and safety device testing with documented results

Install emergency stop controls accessible from both the operating position and the loading area

Recent Prosecutions

Compactor entrapment fatality — Victoria$450,000

A worker was fatally crushed inside a waste compactor after entering the chamber to clear a blockage without implementing lockout-tagout. The compactor interlock had been bypassed with a wire to allow the door to remain open during loading.

What Your SWMS Must Include

✓Interlock and safety device register for each compactor and baler with testing schedule

✓LOTO procedure for chamber entry including ram block and stored energy dissipation

✓Jam clearing procedure prohibiting entry into the compaction chamber without full LOTO

✓Operator competency requirements and training content for each compactor type

✓Biological exposure controls including PPE requirements and sharps injury procedure
