Health Hazards Information -Recommended Personal Protective Equipment: Self-contained breathing
apparatus; goggles or face shield; rubber gloves; Symptoms Following Exposure: Inhalation causes
respiratory tract irritation, headache, dizziness, nausea, and causes mild irritation of skin; General
Treatment for Exposure: INHALATION: in case of pulmonary symptoms, enforce bed rest and give
oxygen; get medical attention at once. INGESTION give large amount of water and induce vomiting.
EYES or SKIN: flush with water; Toxicity by Inhalation (Threshold Limit Value): 25 ppm; Short-Tenn
Inhalation Limits: Data not available; Toxicity by Ingestion: Grade 2; oral rat LD,,=720 glkg; Late
Toxicity: Causes liver cancer in rats; Vapor (Gas) Irritant Characteristics: Vapors cause a slight
smarting of eyes or respiratory system if present in high concentrations. The effect is temporary; Liquid
or Solid Irritm Characteristics: Minimum hazard. If spilled on clothing and allowed to remain, may
cause smarting and reddening of skin; Odor Threshold: 300 ppm.

nitrogen may form in fire; Behavior in Fire: No data; Ignition Temperature (deg. F): 802; Electrical
Hazard: Data not available; Burning Rate: Data not available.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: May
attack some forms of plastics; Stability During Tramport: Stable; Neutralizing Agents for Acids and
Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Health Hazards Information -Recommended Personal Protective Equipment: Self-contained breathing
apparatus (approved mask may be used for short exposures only); rubberized clothing; gloves; shoes;
chemical goggles; Symptoms Following Exposure: Gas is highly toxic. Inhalation causes severe
irritation of respiratory tract and damage to mucous membranes. Delayed effects, which include severe
pulmonary edema, may not be apparent for several hours; General Treatment for Exposure:
INHALATION: remove victim to fresh air; call a doctor; enforce complete rest until doctor arrives;
observe at least 24 hours for delayed effects. SKIN OR EYES: flush with water for at least 15 min.;
consult physician; Toxicity by Inhalation (Threshold Limit Value): 1 ppm (recommended); Short-Tenn
Inhalation Limits: Data not available; Toxicity by Ingestion: Data not available; Late Toxicity: None;
Vapor (Gas) Irritant Characteristics: Vapors cause severe irritation of eye and throat and can cause eye
and lung injury. They cannot be tolerated even at low concentrations; Liquid or Solid Irritant
Characteristics: Severe burns to eyes and skin; Odor 7hreshold: Data not available.
