Hazards and Protection.
Maintain at 2-8 C. Keep container tightly closed. Keep away from heat sources.
Wear protective gloves, goggles and dustproof clothing.
Dust mask with filter type P3.
Stop dust cloud by covering with sand/earth. Solid spill: shovel. Carefully collect the spill/leftovers. Clean contaminated surfaces with an excess of water. Wash clothing and equipment after handling
Release of toxic and corrosive gases/vapours nitrous vapours, carbon monoxide - carbon dioxide upon thermal decomposition.
Dilute toxic gases with water spray. Use compressed air/oxygen apparatus and a gas-tight suid.
On burning: release of toxic and corrosive gases/vapours nitrous vapors, carbon monoxide and carbon dioxide

Irritation or burns of the esophagus or gastrointestinal tract are also possible if caustic or irritant chemicals are ingested.
Causes irritation of the eyes, skin, and respiratory tract. In severe cases respiratory tract irritation can progress to ARDS/acute lung injury which may be delayed in onset for up to 24 to 72 hours in some cases.
Consider gastric lavage after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Administer charcoal as a slurry 240 mL water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents, 25 to 50 g in children (1 to 12 years), and 1 g/kg in infants less than 1 year old. Immediate dilution with milk or water may be of benefit in caustic or irritant chemical ingestions.
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids.
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician may need to examine the area if irritation or pain persists.
Irrigate eye for at least 20 minutes with water or saline. If irritation persists, seek medical attention.
