Dry Ice Safety

Before handling and using dry ice ensure you understand its properties, potential hazards and actions to take in an emergency.

Properties

Dry ice is a solid carbon dioxide. Chemical formula C0₂
Dry ice appears as a translucent white solid which at normal temperatures sublimes from the solid state directly into a gas without passing through a liquid phase.
Non flammable, asphyxiant
Colourless gas with a slightly pungent odour which is only detectable in high concentrations

Hazards

Asphyxiation - In high concentrations sublimed vapour may cause asphyxiation. 10kg of dry ice sublimes into about 5.4 m3 of carbon dioxide gas.
Extreme Cold - Contact with product can cause cold burns or frostbite. The temperature of dry ice is -78ºC.

Tips

Do no handle dry ice with bare hands. It can cause sever cold burns and frostbite
Before using dry ice in any area, establish the risks involved. Ensure you consider the potential for the creation of atmospheres with a high concentration of carbon dioxide near the ground
Only experienced and properly instructed people should handle dry ice
Do not remove or deface any product labels
Know and understand the properties of dry ice
Establish plans of emergency
Always seek professional advice on suitable ventilation systems. Use carbon dioxide monitors to warn of problems
Never play games with dry ice
Always keep dry ice away from children
Water on solid CO₂ increases sublimation with a corresponding higher risk of asphyxiation
Always wear eye protection and heavy insulated gloves suitable for the extreme cold temperature of dry ice. Never handle dry ice with your bare hands - it can cause frostbite.
Dispose of dry ice in a well ventilated area away from the public. Do not discharge into any place where its accumulation could be dangerous
Take care when carrying packages of dry ice
