Due to the large expansion ratio (liquid to gas), if LN2 is evaporating within a closed system, the pressure can build up with a high risk of explosion. Persons using a tipper to dispense LN2 must wear a full face shieldover goggles, cryo-gloves, full length cuffless trousers which completely cover the tops of the shoes (or a full length apron), and shoes which will not permit liqufied gas to enter them in case of a spill, and which are also quickly removable in case they do (allow liquid to enter). 0000001811 00000 n

Do not attempt to handle liquid nitrogen until you read and fully understand the potential hazards, their consequences, and the related safety precautions. Hydrogen as a liquid or cold gas may cause severe frostbite to the eyes or skin. Cryogenic vapour could also be considered as a gas but is dealt with in a separate document. Nitrogen is the earths most plentiful gas. WebThe nitrogen gas produced is capable of displacing oxygen in air, which can lead to: dizziness; nausea; vomiting; unconsciousness; that may endanger a workers safety or health, to use the precautions and procedures to be followed in the handling, use and storage of LN2; in the proper use and care of required PPE;

Tube explosions are thought to be caused by liquid nitrogen entering the tube through minute cracks and then expanding rapidly as the tube thaws. As the oxygen in air is gradually replaced with nitrogen, it becomes harder and harder to initiate an explosion and fire involving a flammable gas or combustible dust (i.e., more energetic ignition sources would be Dewars must never be accompanied in lifts due to the risk of asphyxiation. Guard against pressure build-up by using a pressure relief vessel or a venting lid. 0000010316 00000 n
