AS00.00-Z-0003-01A Risk Of Injury When Handling Liquid Nitrogen Or From Touching Extremely Cool Objects. Risk Of Asphyxiation From Inhaling Nitrogen Gas.

DANGER:
- Wear heat-protective gloves, protective clothing and full eye protection.
- Ensure that the work area is adequately ventilated.

Potential risks

Injury hazard
Contact with liquid nitrogen or extremely cool objects causes frost damage to the skin similar to burns, and severe injury to the eyes.

Risk of asphyxiation
When liquid nitrogen evaporates this produces a nitrogen gas which can cause asphyxiation if it is present in high concentrations, without any noticeable warning.

Safety instructions/precautions
- It is not permitted to eat, drink, smoke or to store foot products in the work area.
- Ensure that the work area is adequately ventilated. Never use liquid nitrogen in the area of assembly pits.
- Treat containers, equipment, valves etc. with particular care; dry well before filling; secure to prevent falling over.
- Do not attempt to eliminate icing on vessels with a flame or glowing object.
- Avoid spilling liquid nitrogen when transferring it or filling it into containers. Always fill containers only up to the mark.
- Wear protective clothing, full eye protection, low temperature- resistant gloves (e.g. leather, kevlar).
- Store liquid nitrogen only in containers provided for this purpose.

First-aid measures
- Do not rub affected areas of the skin; pour plenty of lukewarm water over affected areas and cover over with sterile bandages.
- Immediately remove moistened clothing.
- Take unconscious persons immediately into the fresh air and provide artificial respiration, if necessary.
- Consult a physician without delay.
