Nitrogen (N2) N.F.
Cylinder Color: Black
N2- This colorless, odorless, nonflammable gas constitutes a major portion (78.03% by volume) of the earth’s atmosphere. Nitrogen is relatively nonreactive and can act as a simple asphyxiant by displacing air.
Major Hazards: High Pressure and Suffocation
Exposure Limit: Simple Asphyxiant
Fire Potential: Nonflammable
Odor: None
Mol. Wt.: 28.01
Sp. Gr. (Air = 1) 70° F (21° C): 0.967
Critical Temperature: -232.4° F (-146.9° C)
Critical Pressure: 493 psia (34.7 kg/cm2abs)
Specific Volume: 13.8 ft3/lb at 70° F (0.86 m3/kg at 15° C)
CAS Registry No.: 7727-37-9
D.O.T. Description: Nitrogen, Compressed, 2.2, UN1066
Nitrogen, Refrigerated Liquid, 2.2, UN1977
Medical Applications: As a component in many gas mixtures, as a displacement medium for sterile equipment, as a nonoxidizing displacement medium in pharmaceutical vials, as a propellant in pressurized aerosol type dispensers, as a coolant for carbon dioxide surgical lasers and as a source of pressure to power pneumatic medical devices.
