Meat Processing (Abattoir / Boning Room) SWMS

Abattoir kill-floor and boning-room operations combine high-energy plant, sharp hand tools, biological hazards and confined-space chemical risks within a single workflow — making them among the most hazardous fixed workplaces in Australian primary industry. Workers handle live animals at the stun-box, operate captive-bolt devices, perform thousands of repetitive knife cuts per shift, enter chillers below 4°C, and clean down with caustic and acid sanitisers. WHS Regulation 2025 Chapter 4 Part 4.5 requires a documented Safe Work Method Statement before any work involving powered plant, hazardous chemicals or biological agents commences, and Part 7.1 specifically captures CO2 stunning systems as a confined-atmosphere risk. The Food Standards Code and PrimeSafe / state meat authority licensing further mandate written safe operating procedures for every task that affects worker or product safety. This SWMS consolidates those overlapping duties into a single controlled document covering kill-floor through to boning-room dispatch.

Control measures

Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.

1. 1Elimination — Remove personnel from the stun-box pit by retrofitting remote camera inspection and automated jam-clearing rams so workers never enter the CO2 atmosphere during normal operations.
2. 2Elimination — Eliminate manual knife sharpening at the workstation by rotating dull knives to a central sharpening room operated by a dedicated sharpener under separate SWMS controls.
3. 3Substitution — Substitute reciprocating powered boning knives for fixed-blade knives on high-volume cuts to reduce grip force and repetition cycles per shift consistent with the Hazardous Manual Tasks CoP.
4. 4Substitution — Replace concentrated caustic with pre-diluted ready-to-use sanitiser cartridges to remove manual decanting and reduce splash exposure during CIP changeovers.
5. 5Engineering — Install continuous CO2 atmosphere monitors with audible and visual alarms at 0.5% and automatic exhaust fan trip at 1.5% in the stun-box pit per AS/NZS 60079 atmosphere classification.
6. 6Engineering — Fit captive-bolt devices with mechanical trigger guards, dual-action firing and lock-off keys retained by the licensed slaughterer only, per AS/NZS 4837 humane slaughter plant guidance.
7. 7Administrative — Implement chain-speed limits and mandatory micro-pause rotation every 20 minutes with task variation across sticking, legging, hide-pulling and evisceration positions to reduce cumulative MSD load.
8. 8Administrative — Mandate Q-fever vaccination screening and serology for all kill-floor workers before commencement, with records retained under WHS Regulation 2025 health monitoring provisions for 30 years.
9. 9PPE — Issue cut-resistant chainmail aprons, mesh gloves to ANSI A9, steel-mesh wrist guards, kevlar-lined sleeves, and impact face shields for stunning and sticking positions inspected each shift.
10. 10PPE — Provide chemical splash goggles, nitrile gauntlets, neoprene aprons and powered air-purifying respirators with organic vapour cartridges for sanitiser handling and high-pressure wash-down tasks.

Applicable Codes of Practice

Worked example

At a mid-sized cattle abattoir in regional Australia, the day-shift kill-floor supervisor runs the 5:45am pre-start brief with twelve slaughterers, stickers and offal workers gathered at the chain entry. She opens the Meat Processing SWMS on the wall-mounted tablet and walks through the day's specific risks: a new sticker is rotating onto the chain, last night's CIP wash left residual peracetic odour near the legging station, and the stun-box CO2 monitor logged a 0.4% spike at 4am. Workers identify that the spike, combined with planned pit maintenance at smoko, triggers the confined-space entry control — the SWMS requires atmospheric clearance below 0.1%, standby rescuer, tripod and SCBA before entry, so she reschedules the maintenance to after-shift when the gondola can be fully purged. The new sticker signs onto the document acknowledging the cut-resistant apron, mesh glove and Q-fever vaccination prerequisites. Mid-shift, a brisket saw vibration alarm sounds; the leading hand pauses the chain, opens the SWMS plant-isolation section on the tablet, applies the documented lock-out sequence and tags the saw out. After mechanical inspection clears the fault, the SWMS sign-on register is updated before the chain restarts. At end-of-shift, the supervisor records the CO2 reading, the saw isolation event and the rescheduled pit entry in the SWMS review log, which becomes evidence for the next monthly WHS committee meeting and PrimeSafe audit.
