Environmental Health and Safety. What is Liquid Nitrogen? Liquefied form of nitrogen (N2) gas. When in the gaseous phase, it is a mostly inert gas, that is colorless, odorless, and tasteless. In the liquid phase, it's very cold (BP=-195.8°C), which makes it ideal to transport cold materials. This however This SDS conforms to U.S. Code of Federal Regulations 29 CFR 1910.1200, Hazard Communication. Date of issue: 01/01/1979 . 7.3. Specific end use(s). None. SECTION 8: Exposure controls/personal protection. 8.1. Control parameters. Nitrogen, refrigerated liquid (7727-37-9). ACGIH. Not established. USA OSHA. The purpose of these guidelines is to provide information for the safe handling of liquid nitrogen. The VA Several of the VAPHS research laboratories utilize liquid nitrogen for cryopreservation of biological samples or for storage of cell lines. . The Occupational Safety and Health Administration (OSHA) specifies that a The use of compressed gases and liquid nitrogen presents many safety issues for laboratory staff and support personnel. This chapter will identify the hazards associated with compressed gases and liquid nitrogen, discuss the regulations issued by OSHA and NFPA regarding gas cylinder storage and handling, outline to produce nitrogen. Nitrogen can be liquefied at very low temperatures, and large volumes of liquid nitrogen can be effectively transported and stored. Nitrogen does not tion (OSHA) considers any atmosphere with an oxygen level below 19.5% to be .. tional Safety and Health Guideline for Nitrogen,” www.osha.gov/. Filling between containers, leaking valves, and liquid tank venting are some examples that could lead to an oxygen deficient atmosphere. 8. Handling Liquid Nitrogen. Always read the container label prior to use. Cryogenic liquid containers must always be stored in the upright position. Cryogenic liquids should not be Nitrogen (cryogenic liquid) N2 No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values. On loss of containment this liquid evaporates very quickly causing supersaturation of the air with serious risk of suffocation when in confined areas. Cryogens are substances used to produce very low temperatures [below -153°C (-243°F)], such as liquid nitrogen (LN2) which has a boiling point of -196°C. (-321°F), that are commonly used in laboratories. Although not a cryogen, solid carbon dioxide or dry ice which converts directly to carbon dioxide gas at. 1) Provide guidance on the installation, maintenance, and calibration of oxygen monitoring and nontoxic. When liquid nitrogen and/or helium are dispensed they release nitrogen and/or helium gas, which Occupational Safety and Health Administration (OSHA) specifies that a hazardous atmosphere may include one
