Page 2 of 8
EFFECTS OF A SINGLE (ACUTE) OVEREXPOSURE:
INHALATION–Asphyxiant. Effects are due to lack of oxygen. Moderate concentrations may cause
headache, drowsiness, dizziness, excitation, excess salivation, vomiting, and unconsciousness. Lack
of oxygen can kill.
SKIN CONTACT–No harm expected.
SWALLOWING–An unlikely route of exposure. This product is a gas at normal temperature and
pressure.
EYE CONTACT–No harm expected.
EFFECTS OF REPEATED (CHRONIC) OVEREXPOSURE: No harm expected.
OTHER EFFECTS OF OVEREXPOSURE: Asphyxiant. Lack of oxygen can kill.
MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE: The toxicology and the
physical and chemical properties of nitrogen suggest that overexposure is unlikely to aggravate existing
medical conditions.
SIGNIFICANT LABORATORY DATA WITH POSSIBLE RELEVANCE TO HUMAN HEALTH
HAZARD EVALUATION: None known.
CARCINOGENICITY: Nitrogen is not listed by NTP, OSHA, or IARC.
4. First Aid Measures
INHALATION: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult,
qualified personnel may give oxygen. Call a physician.
SKIN CONTACT: Flush with water. If discomfort persists, seek medical attention.
SWALLOWING: An unlikely route of exposure. This product is a gas at normal temperature and
pressure.
EYE CONTACT: Flush eyes thoroughly with water. Hold the eyelids open and away from the eyeballs
to ensure that all surfaces are flushed thoroughly. If discomfort persists, seek medical attention.
NOTES TO PHYSICIAN: There is no specific antidote. Treatment of overexposure should be directed
at the control of symptoms and the clinical condition of the patient.
5. Fire Fighting Measures
FLASH POINT (test method): Not applicable
AUTOIGNITION TEMPERATURE: Not applicable
FLAMMABLE LIMITS IN AIR, % by volume:LOWER:Not applicable UPPER: Not applicable
EXTINGUISHING MEDIA: Nitrogen cannot catch fire. Use media appropriate for surrounding fire.
SPECIAL FIRE FIGHTING PROCEDURES: CAUTION! High-pressure gas. Asphyxiant. Lack of
oxygen can kill. Evacuate all personnel from danger area. Immediately deluge cylinders with water from
maximum distance until cool; then move them away from fire area if without risk. Shut off flow if you
can do so without risk. Self-contained breathing apparatus may be required by rescue workers. (See
section 16.) On-site fire brigades must comply with OSHA 29 CFR 1910.156.
