Hazards and Protection.
Keep well closed.
Containers of this material may be hazardous when emptied. Since emptied containers retain product residues (vapor, liquid, and/or solid), all hazard precautions given in the data sheet must be observed.
Protective clothing including overalls, gloves and footwear should be worn. Some operations may necessitate use of resp protective equipment and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers.
Can detonate other materials. Reactive only under extreme conditions.
May react explosively.
When heated to incandescence, calcium nitrate decomposition into nitrogen oxide, calcium oxide and oxygen on decomposition, emits toxic fumes of nitrogen oxides.
Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Moderate - by spontaneous chemical reaction, oxidizing material.
May explode from heat or contamination. May react explosively with hydrocarbons (fuels). May ignite combustibles.
May give off toxic oxides of nitrogen when involved in fire.
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. 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.
Flush with water and seek medical assistance.
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.
