Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. To extinguish fire, use water fog, dry chemical, carbon dioxide, or regular foam.
Decomp is self-sustaining @ 280 deg c. Closed containers may rupture violently when heated.
Nitrogen oxides and dense black smoke are produced in a fire.
TLV: ppm; 1.5 mg/m3 (as TWA) (skin) (ACGIH 1996).
There is a danger of cumulative effects.
Harmful if swallowed. Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May cause allergic reaction. Ingestion of nitrate containing compounds can lead to methemoglobinemia.
Causes respiratory tract irritation. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate and chocolate-brown blood. This product contains nitrite which may cause methemoglobinemia.
Causes skin irritation.
Causes eye irritation.
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid.
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Get medical aid immediately. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
