Hazards and Protection.
Keep away from heat, sparks, and flame. Refrigerator/flammables.
Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Avoid contact with heat, sparks and flame. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Eyes: Wear chemical goggles. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin.
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.
Clean up spills immediately, using the appropriate protective equipment.
Stable under normal temperatures and pressures.
If mixed with reducing agents, including hydrides, sulfides, nitrides, ammonium salts, cyanides, and many fuels.
Irritating and toxic fumes and gases.
Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher.
This chemical is flammable.
Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion and poison hazard indoors, outdoors or in sewers.
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.
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid immediately.
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. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Remove contaminated clothing and shoes.
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
