Hazards and Protection.
Keep tightly closed, in a cool place, protected from light. Store away from heat, oxidizers, and sunlight. Must be stored in a dry location. Outside or detached storage is preferred.
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.
Goggles, or face shield; rubber gloves.
Self-contained breathing apparatus.
Make no contact with the spilled material. Fully encapsulating, vapor protective clothing should be worn for spills and leaks with no fire. ELIMINATE all ignition sources and ground all equipment. Stop leak if you can do it without risk. A vapor suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean non-sparking tools to collect absorbed material.
On keeping, it gradually decomposes, becoming acid and oxides of nitrogen form. Decomposes is hastened by air, light, and moisture.
Highly dangerous; when heated to decomposition or on contact with acid or acid fumes, emits highly toxic fumes of no(x).
Use of water spray when fighting fire may be inefficient. Small Fires: Dry chemical, carbon dioxide, water spray or alcohol-resistant foam. Large Fires: Water spray, fog or alcohol-resistant foam.
Closed containers may rupture violently when heated.
Fire will produce irritating, corrosive and/or toxic gases.
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.
Initial effects of ingestion are gastric irritation with nausea, vomiting and abdominal pain.
Respiratory depression and cyanosis may be noted, due to methemoglobinemia.
Cyanosis that minimally responds to oxygen therapy may be noted, and is indicative of probable methemoglobinemia.
Visual field defects have been reported in sodium nitrite poisoning.
Immediate life support measures should be provided because of associated hypotension, seizures, and methemoglobinemia-induced anoxia. Emesis: ipecac-induced vomiting is not recommended because of the potential for seizures.
Move patient to fresh air. Monitor for respiratory distress. Administer oxygen and assist ventilation as required. Treatment should include recommendations listed in the oral exposure section when appropriate.
Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush with running water for at least 20 minutes. Wash skin with soap and water.
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.
