Decomposition
Nitrogen oxides.

Fire.
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Strong oxidizer. Contact with combustible materials may cause a fire. Substance is noncombustible. Extinguishing media: Use water spray to cool fire-exposed containers. Use water only!

Health.
Exposure limit(s)
OSHA PEL: 15 mg/m3 total dust, 5 mg/m3 respirable fraction for nuisance dusts.
Poison_Class
3
Exposure effects
Orthostatic abnormally low blood pressure and rapid heart rate are common. Abnormally low blood pressure and low heart rate are possible. Throbbing headache is common. Seizures have been reported following severe intoxication. Behavioral deficits were observed in the adult offspring of rats who received sodium nitrite prenatally.
   Ingestion
Expected to be a low ingestion hazard.
   Inhalation
May cause respiratory tract irritation.
   Skin
May cause skin irritation.
   Eyes
May cause eye irritation.

First aid
 
   Ingestion
Get medical aid. Wash mouth out with water.
   Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
   Skin
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
   Eyes
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
