Khi c tc p[]. Liquid nitrogen poses oxygen deficiency hazards in addition to freezing hazards. Did You Know? In the U.S., nitrogen asphyxiation hazards caused 80 deaths from 1992 to 2002 and 14 from 2012 to 2020 (1). These incidents occurred in a variety of facilities, including industrial plants, laboratories, and medical facilities. If the vessel is too large for the table, or the table is missing or inoperable, other provisions must be made for safely raising the vessel up to the delivery tube. 0000004334 00000 n
7. The safety precautions as outlined must be followed to avoid potential injury or damage which could result from these two characteristics. 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. WebBottle Safety Instruction. ________________________________________________________________________________, _____________________________________________________________________________________, ___________________________________________________________________________________, _______________________________________________________________________________________________________. Inside buildings, from room to room, the best transport is by Dewars which either have carrying handles (4 L and less) or are on wheels (larger Dewars), and which have pressure relief valves or pressure venting lids. Never dispose of liquid nitrogen by pouring on the floor or on pavement. For detailed information, please consult the Material Safety Data Sheet (MSDS) on hydrogen.

Take every precaution to prevent hydrogen leaks. The control measures required in facilities used for using and/or storing LN2 differ depending on the lowest likely oxygen level. WebAll gases under pressure (even non-hazardous gases such as nitrogen) must comply with the relevant sections of the Health and Safety at Work (Hazardous Substances) Regulations 2017. Risk assessments must be completed by each area where LN2 is handled and stored using the information detailed in the Safety Data Sheet (SDS) and that which is detailed below. Safe work instructions must then be developed and control measures implemented and followed. Hydrogen is a flammable gas.
