Oxygen in Nitrogen 0.0001% to 5%

SECTION 2: Hazards identification

Emergency Overview: Odorless, colorless, nonflammable gas. Simple Asphyxiant – This product does not contain oxygen in sufficient quantities to support life and may cause asphyxia if released in a confined area. Maintain oxygen levels above 19.5%. Contents under pressure. Use and store below 1250F (52O C).

Exposure Limits Irritant Sensitization No Teratogen Reproductive Hazard Mutagen No Synergistic Effects None reported NorLab, Oxygen in Nitrogen 0.0001% to 5% Material Safety Data Sheet 2390 Page 2 of 5 Continued Carcinogenicity: NTP: No IARC: No OSHA: No Eye Effects: Contact with rapidly expanding gas near the point of release may cause frostbite. Skin Effects: Contact with rapidly expanding gas near the point of release may cause frostbite with redness, skin color change to gray or white, and blistering. Ingestion Effects: None known. Ingestion is unlikely as product is a gas at room temperature. Inhalation Effects: Gas mixture does not contain sufficient oxygen to support life and acts as a non-toxic simple asphyxiant. Effects of oxygen deficiency resulting from simple asphyxiants may include: rapid breathing, diminished mental alertness, impaired muscular coordination, faulty judgment, depression of all sensations, emotional instability, and fatigue. As asphyxiation progresses, nausea, vomiting, prostration, and loss of consciousness may result, eventually leading to convulsions, coma, and death. Oxygen deficiency during pregnancy has produced developmental abnormalities in humans and experimental animals.
