Hazards and Protection.
Storage
Keep containers tightly closed in a well ventilated area away from food products. Keep away from heat and water, and contact with organic material. Avoid storing on wood floors, due to fire hazard.
Handling
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.
Protection
Dust mask; 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). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
Stability
Stable.
Incompatibilities
Mixtures with alkyl esters may explode, owing to the formation of alkyl nitrates Mixtures with phosphorus, tin(II) chloride or other reducing agents
Decomposition
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
Strong oxidizer, may react violently with some reducing materials causing fire. Otherwise noncombustible.
Hazards
May explode from heat or contamination. May react explosively with hydrocarbons (fuels). May ignite combustibles.
Combustion products
Toxic oxides of nitrogen and nitric acid vapor may form in fires.

Exposure effects
Blood pressure may be decreased following an iron overdose. Lethargy, restlessness or confusion may be seen early in the poisoning. Convulsions and coma may occur in later phases. Case reports of pregnant women who have received early aggressive treatment (decontamination and/or deferoxamine) have described good fetal outcomes.
   Ingestion
Nausea, vomiting, diarrhea and gastrointestinal hemorrhage may develop.
   Inhalation
Noncardiogenic pulmonary edema may develop with severe intoxication.
   Skin
Severe thermal burn with ferrous sulfate slurry has caused classical symptoms of ingested iron poisoning.
   Eyes
Visual field defects have been reported in sodium nitrite poisoning.

First aid
 
   Ingestion
The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. Activated charcoal activated charcoal binds most toxic agents and can decrease their systemic absorption if administered soon after ingestion. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
   Inhalation
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.
   Skin
Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush with running water for at least 20 minutes.
   Eyes
In case of contact with substance, immediately flush with running water for at least 20 minutes.
