Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Special Hazards: At high temperatures, can decompose and release ammonia and hydrogen chloride gases, both irritating and corrosive
Protective Equipment: Full protective clothing with self-contained breathing apparatus for firefighters
Advice for Firefighters: Stay upwind, prevent firefighting water from entering drains
Personal Precautions: Use proper personal protection including dust mask, goggles, gloves
Environmental Precautions: Avoid release into waterways, prevent spillage from entering drains, report large releases as per local regulation
Methods for Cleaning Up: Sweep and collect spilled material, avoid dry sweeping, vacuum with HEPA filter if possible, place in suitable container for proper disposal, wash spill site with water after cleanup
Precautions for Safe Handling: Avoid inhaling dust and direct contact with skin and eyes, work in well-ventilated areas, keep containers tightly closed when not in use, wash hands after use
Conditions for Storage: Store in dry, cool, well-ventilated environment, protect from moisture and incompatible materials like strong bases and oxidizers
Storage Container Materials: Use original containers, close lids tightly, keep away from sources of heat, acids, and alkalis
Permissible Exposure Limits: OSHA PEL: 10 mg/m3 (total dust), ACGIH TLV: 10 mg/m3
Engineering Controls: Local exhaust ventilation to reduce airborne concentration, enclosed process equipment where feasible
Personal Protective Equipment: Safety glasses or goggles, chemical-resistant gloves, dust mask or respirator in dusty environments, lab coat or work clothes
Hygiene Measures: Wash hands thoroughly after handling, launder contaminated clothing before reuse, keep eating and drinking out of work area

Inhalation: May cause irritation of nose, throat, lungs, coughing, breathing difficulty at high concentrations
Skin Contact: Prolonged exposure may cause mild irritation
Eye Contact: Risk of redness, pain, severe irritation with direct contact
Chronic Effects: Long-term excessive exposure can impact kidney, liver, result in metabolic imbalances; limited evidence in humans
Carcinogenicity: Not listed as carcinogenic by IARC, NTP, or OSHA
Other Effects: Sensitive individuals may react at lower levels; always best to limit prolonged or repeated exposure
Ecotoxicity: Toxic to aquatic organisms in high concentrations, particularly in small or enclosed water bodies
Persistence and Degradability: Product dissociates in water, ammonium ion can be nitrified by bacteria to nitrate
Bioaccumulative Potential: Low, little potential for buildup in organisms
Mobility in Soil: Moves readily with water, limited adsorption to soil particles, may leach to ground water
Other Effects: Contributes to eutrophication in nutrient-sensitive water systems, can harm algae and aquatic invertebrates
Waste Disposal Methods: Dispose of in accordance with local, regional, national regulations; avoid disposal into drains or natural water courses
Container Handling: Dispose of contaminated containers as hazardous waste if they cannot be cleaned
Neutralization: For small quantities, dissolve in water, dilute, and neutralize under professional supervision before controlled disposal
Recycling: Product and packaging recycling options depend on contamination, check with regional waste management authorities
