Hazards and Protection.
Storage
Keep containers tightly closed in a well ventilated area away from food products. Keep away from heat, organic materials, and water.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Niosh-certified respirator; goggles or face shield; protective gloves
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Water spill: Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). Adjust pH to neutral (pH=7).
Stability
Dangerous explosion risk in contact with organic materials.
Incompatibilities
May react explosively.
Decomposition
On decomposition it emits toxic fumes of nitrogen oxides.

Fire.
Fire fighting
Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Fire potential
Dangerous fire risk in contact with organic materials.
Hazards
May explode from heat or contamination. May react explosively with hydrocarbons (fuels). May ignite combustibles.
Combustion products
Toxic oxides of nitrogen may form in fire.

Health.
Exposure effects
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
Initial effects of ingestion are gastric irritation with nausea, vomiting and abdominal pain.
   Inhalation
Respiratory depression and cyanosis may be noted, due to methemoglobinemia.
   Skin
Cyanosis that minimally responds to oxygen therapy may be noted, and is indicative of probable methemoglobinemia.
   Eyes
Visual field defects have been reported in sodium nitrite poisoning.

First aid
 
   Ingestion
Give large amount of water.
   Inhalation
Move to fresh air.
   Skin
Flush with water.
   Eyes
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
