[PDF] Procedures for Handling Liquid Nitrogen (LN2)

Liquid Nitrogen Handling and Use - Cornell University

LN2 Eyes are most sensitive to the extreme cold of LN2 and its vapors Over-pressurization may result in the explosion of improperly vented equipment Chemical splash goggles must be utilized when handling LN2 and when handling sealed containers that have been stored in LN2 (e g , cryovails)

Procedures for Handling Liquid Nitrogen (LN2)

Procedures for Handling Liquid Nitrogen (LN2) Liquid Nitrogen is a cryogenic material with three main hazards: asphyxiation, frostbite, and explosion Death by asphyxiation can occur if the liquid is allowed to boil off or is spilled in

LABORATORY SAFETY GUIDELINE - Harvard University

LN2 or uninsulated equipment (piping, cold traps, etc ) containing LN2 can liquefy the air they contact Nitrogen will evaporate before the oxygen in the liquefied air, which can result in a localized oxygen-enriched environment that accelerates oxidation and combustion of organic materials

Standard Operating Procedure for Filling a Liquid Nitrogen

1 When LN2 begins to come out the vent hose into the exhaust, close red handle on LN2 filler line (to point towards external building wall) 2 Push the timer button to stop the 10 minute flow timer for the LN2 3 Close the vent and liquid taps all the way on the 160 ltr LN2 dewar and immediately conduct #3 4

Liquid Nitrogen Distribution System Preliminary Design Review

The LN2 manifolds and hoses connect to and are mechanically supported by the coil support structures • Cryogenic Systems (WBS 62) Supply and return lines carrying LN2 to/from the supply/return headers connecting to the LN2 supply system outside the cryostat wall and outboard of the WBS 161 LN2 valves and pressure gauges, as well

Safe Handling and Use of Liquid Nitrogen

Handling LN 2: Transferring from Primary Container Always wear safety equipment including heavy loose- fitting leather or cryogenic gloves, and eye and face protection Prior to use, ensure the fittings on the regulator

Material Safety Data Sheet: Liquid Nitrogen

CryoWiz™ Liquid Nitrogen Cryogenic Switchover

Nitrogen is a colorless, odorless, tasteless gas Liquid nitrogen (LN2) is a potential asphyxiate and may cause severe frostbite Please observe all proper safety precautions to ensure proper handling of LN2 Consult your local LN2 Dealer for detailed handling instructions
