Cryogenic Burns

In general

Cryogenic burns are cold burns caused by liquefied gases e.g. liquid N2

Burns caused by contact with liquefied gases may not be immediately apparent but can develop some time later. The skin will appear white and waxy. The affected area should be thawed slowly in lukewarm water, never hot, then covered with a sterile dressing. If any clothing etc is frozen onto the skin, do not attempt to remove it until the area has been completely thawed. If the burn is extensive or deep (indicated by a loss of sensation in the area) then seek medical advice.

No one may use the storage facility or draw off Liquid Nitrogen from the Take Off Point without having first received instruction from the Health and Safety Coordinator, Graham Frost.

Use of Liquid Nitrogen

Protective gloves or gauntlets and eye protection, preferably a full-face shield must be worn at all times when handling liquid nitrogen. It is also advisable to make sure you are wearing suitable footwear, i.e. no open-toed sandals. A raised platform of steel mesh is provided for users to stand on which will prevent spilled liquid nitrogen from accumulating around the feet.

Use of Storage Facility

Excess liquid must be allowed to drain from sections before they are lifted out of the dewar. Take care when lifting the sections as they are heavy.
