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.
