Cold Room Entry SWMS

Cold rooms, blast freezers, and coolrooms in food processing facilities operate at temperatures from minus 25 to plus 4 degrees Celsius. Workers who enter cold rooms face hypothermia risk during extended stays, entrapment if door mechanisms fail, and ammonia exposure in facilities with ammonia refrigeration systems. Forklift operations inside cold rooms create interaction hazards with pedestrian workers in confined, low-visibility environments. Ice accumulation on floors creates severe slip hazards. This template addresses exposure time limits, emergency release mechanisms, and monitoring requirements under the WHS Regulation 2025.

Hazards

Hazard	Consequence	Likelihood
Hypothermia from extended exposure to sub-zero temperatures	Core temperature drop, confusion, cardiac arrest, death	Possible
Entrapment from cold room door mechanism failure	Prolonged cold exposure, hypothermia, death	Unlikely
Ammonia exposure from refrigeration system leak inside cold room	Chemical burns to lungs, asphyxiation, death	Unlikely
Slip and fall on ice-covered cold room floors	Fractures, head injuries, sprains	Likely
Forklift-pedestrian collision in confined cold room space	Crush injuries, fractures, death	Possible
Reduced dexterity from cold affecting safe equipment operation	Dropped loads, equipment mishandling, injuries	Likely

Controls (Hierarchy of Controls)

Install and test internal door release mechanisms on all cold rooms and blast freezers

Install alarm buttons inside all cold rooms that alert external personnel when activated

Set maximum continuous exposure times based on temperature: 60 minutes at 0°C, 30 minutes at -18°C, 15 minutes at -25°C

Provide insulated cold weather PPE including thermal suits, gloves, and safety boots rated to the operating temperature

Maintain ice-free floors using anti-slip treatments and regular defrosting schedules

Separate pedestrian and forklift zones inside cold rooms where space permits

Install ammonia detectors inside cold rooms with audible and visual alarms

Implement a buddy system or sign-in register for all cold room entry to track occupancy
