General Advice: Remove contaminated clothing and shoes immediately; move exposed person to fresh air
Inhalation: Move to fresh air, keep at rest, call poison center or doctor, provide artificial respiration if not breathing
Skin Contact: Wash immediately with soap and water for at least 15 minutes; seek medical attention if irritation persists
Eye Contact: Rinse cautiously with water for several minutes; remove contact lenses if present and easy; seek immediate medical care
Ingestion: Rinse mouth with water, do not induce vomiting, call poison center or medical professional right away
Medical Attention: Give supportive care as needed; monitor vital signs; no specific antidote
Extinguishing Media: Use large amounts of water, do not use dry chemicals or carbon dioxide on bulk material
Special Hazards: Powerful oxidizer, may detonate if strongly heated or shocked; decomposes to toxic gases including nitrogen oxides and ammonia
Protective Equipment: Full protective gear, self-contained breathing apparatus (SCBA), gloves, boots
Fire/Explosion Risk: Risk of explosion in confined or heated spaces, may re-ignite after initial suppression
Evacuation Procedures: Clear area, keep bystanders at safe distance, cool containers from far away with water spray
Specific Firefighting Procedures: Approach from upwind; contain runoff to prevent environmental contamination
Personal Precautions: Ventilate area, evacuate non-essential personnel, use process enclosures or exhaust ventilation
Protective Equipment: Chemical-resistant gloves, safety goggles, impervious clothing, dust mask/respirator
Emergency Procedures: Alert emergency services, secure area, avoid generation of dust
Spill Containment: Carefully scoop up material with non-sparking tools, place into labeled explosion-proof container; avoid contact with combustibles
Cleanup Method: Wash spill area thoroughly, dispose of contaminated cleanup materials according to regulations
Environmental Precautions: Prevent entry into sewers, waterways, or soil; notify authorities if release creates environmental hazard
Handling: Use only in well-ventilated spaces, minimize dust generation, avoid shock or friction, ground all handling equipment
Storage Conditions: Store in cool, dry, explosion-proof location, away from heat, flame, or incompatible materials such as reducing agents, metals, and organic substances
Storage Containers: Use tightly sealed, labeled, corrosion-resistant containers; do not store in bulk above recommended quantity
Incompatible Materials: Strong acids, strong bases, organic solvents, metal powders, combustible materials
Special Rules: Keep separate from food, drink, animal feed, and out of reach of untrained personnel
Permissible Exposure Limits: No specific OSHA PEL or ACGIH TLV; avoid all unnecessary exposure
