Dry Ice Safety Handling Guide for Warehouse Workers

Dry Ice Safety for Warehouse Workers

Dry ice is an essential tool in cold chain logistics, but improper handling can cause frostbite, asphyxiation, and pressure-related injuries. Every warehouse worker who handles dry ice shipments needs to understand the hazards and follow proper safety procedures. Go Freight’s dry ice training program ensures all personnel handle this material safely.

Understanding Dry Ice Hazards

Dry ice presents three primary hazards in warehouse environments. Contact burns occur because dry ice at negative 78.5°C causes severe frostbite on contact with bare skin. Asphyxiation risk exists because sublimating CO2 gas displaces oxygen in enclosed spaces — a CO2 concentration above 10% can cause unconsciousness. Pressure buildup happens when dry ice sublimates in sealed containers, potentially causing explosive rupture.

Required Personal Protective Equipment

Workers handling dry ice must wear insulated cryogenic gloves rated for extreme cold temperatures, safety goggles or face shields to protect against flying ice chips, long-sleeved shirts and long pants with closed-toe shoes, and a ventilated work area. Never handle dry ice with bare hands, even briefly. The extreme cold causes tissue damage within seconds of contact.

Ventilation Requirements

Any area where dry ice is stored or handled must have adequate ventilation to prevent CO2 buildup. Warehouses should have CO2 monitors in areas where dry ice is regularly used, with alarms set to trigger at concentrations above 5,000 ppm. Loading docks, coolers, and enclosed rooms where dry ice packages are opened are particular risk areas. Go Freight’s warehouse partners maintain proper ventilation for dry ice operations.

Storage Best Practices

Dry ice should be stored in well-ventilated areas in insulated but not airtight containers. Never store dry ice in walk-in freezers, sealed rooms, or vehicles with closed windows. The sublimation rate in South Florida’s heat is higher than in cooler climates, so plan for faster dry ice consumption and more frequent replenishment.

First Aid for Dry Ice Injuries

If skin contacts dry ice, do not rub the affected area. Gently warm the skin with lukewarm water (not hot). For significant frostbite, seek medical attention immediately. If someone shows signs of CO2 overexposure (dizziness, headache, rapid breathing), move them to fresh air immediately and call emergency services. Go Freight maintains first aid protocols for dry ice injuries at all handling facilities.
