Hazardous Combustion Products: Nitrogen oxides, ammonia, toxic gases may form
Special Protective Equipment for Firefighters: Wear full protective gear and self-contained breathing apparatus
Specific Hazards: Strong oxidizer, intensifies fire, can detonate under heating or shock, toxic fumes
Firefighting Instructions: Evacuate area, cool containers with water from safe distance, do not let runoff enter drains
Personal Precautions: Evacuate non-essential personnel, remove ignition sources, wear protective clothing and respiratory protection
Environmental Precautions: Avoid release to environment, contain spillage, prevent entry into waterways and soil
Methods for Cleaning Up: Use non-sparking tools, pick up mechanically, place in appropriate waste container for disposal, wash area with large amount of water
Reference to Other Sections: See also disposal and protective equipment guidance
Handling Practices: Keep away from heat, sparks, static discharge, and open flames, handle in well-ventilated area, avoid inhalation and direct contact
Advice on Safe Storage: Store in cool, dry, secure facility, separate from acids, reducing agents, and combustibles, use explosion-proof fixtures
Container Requirements: Keep container tightly closed in approved safety containers, check for leaks regularly
Special Measures: Maintain proper inventory control, limit quantities accessible at any given time, ensure proper training for staff handling this material
Hygiene Practices: Wash hands after handling, avoid eating, drinking, or smoking near storage area
Occupational Exposure Limits: No specific OSHA or ACGIH limits for urea nitrate; treat as nuisance particulate where applicable
Engineering Controls: Work in chemical fume hood or with local exhaust ventilation, ground all equipment to prevent static discharge
