Specific Risks - 2.1 Low temperature hazards

2.1.1 - Cryogenic burns: nitrogen

Liquid nitrogen, or surfaces which have been in contact with liquid nitrogen, can cause serious cryogenic burns. Ensure all users are trained in the correct handling of cryogenic liquids and that correct PPE is available and used.

2.1.2 - Cryogenic burns: ethane

Note that ethane is maintained at a temperature close to its freezing point while in the instrument and so can inflict more serious burns than liquid nitrogen which is always at its boiling point. Exercise particular care.

2.1.3 - Frostbite

Exposure of unprotected skin to cold atmospheres can lead to frostbite. In case of frostbite: 

1. Spray the affected area with water for at least 15 minutes.
2. Apply a sterile dressing.
3. Get medical attention.
