Hazards and Protection.
Protect against physical damage. Store at in cool, dry place, avoid storage on wood floors. Separate from combustible, organic or other readily oxidizable materials. Immediately remove and dispose of any spilled nitrate.
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.
Wear self-contained breathing apparatus during firefighting. Skin protection and filter mask recommended.
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. 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). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
May react explosively.
Copper oxide, nitrogen oxides
Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Slightly flammable. Combustion requires preheating.
May explode from heat or contamination. May react explosively with hydrocarbons (fuels). May ignite combustibles.
Toxic and irritating oxides of nitrogen may form in fire.
NIOSH REL*: TWA 1 mg/m3 OSHA PEL*: TWA 1 mg/m3 [*Note: REL and PEL also apply to other copper compounds (as Cu) except copper fume.] IDLH 100 mg/m3 (as Cu)
Increased temperature may be noted in some cases. Abnormally low blood pressure may occur. 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.
Give large amounts of water; induce vomiting; get medical attention.
Move to fresh air.
Flush with water.
Flush with water for at least 15 min.; get medical attention if injury was caused by solid.
