Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide for small fires
Specific Hazards: May release toxic fumes of nitrogen oxides, carbon oxides on thermal decomposition
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear to avoid exposure
Special Precautions: Evacuate area and fight fire from a safe distance, prevent runoff from contaminating waterways

Accidental Release Measures

Personal Precautions: Evacuate unnecessary personnel, don protective equipment including gloves, goggles, and mask
Environmental Precautions: Prevent spillage from entering drains, sewers, or natural waterways, contain large spills with sand, earth, or inert material
Spill Cleanup: Absorb small liquid spills on inert material and transfer to a chemical waste container, ventilate area thoroughly, wash spill site after material pickup
Disposal: Containers must be properly labeled and disposed of through certified hazardous waste handlers

Handling and Storage

Safe Handling: Avoid direct contact with skin, eyes, or clothing, use only with adequate ventilation or suitable exhaust systems, do not eat, drink, or smoke while handling this chemical
Storage Conditions: Store in a tightly sealed container in a cool, dry, and well-ventilated place, keep out of direct sunlight and away from incompatible materials such as strong oxidizers and acids
Storage Class: Chemical storage areas designed to minimize cross-contamination and provide secondary containment
Incompatibilities: Avoid contact with reactive or oxidizing agents

Exposure Controls and Personal Protection

Exposure Limits: No established occupational exposure limits from OSHA, NIOSH, or ACGIH
Engineering Controls: Use local exhaust ventilation, chemical fume hoods, or process enclosures to control airborne contamination
Personal Protection: Wear chemical-resistant gloves (nitrile, neoprene), close-fitting safety goggles, laboratory coat or protective clothing
Respiratory Protection: Employ certified respirators during dust, vapor, or aerosol formation conditions
Hygiene Measures: Practice routine hand washing and removal of contaminated clothing before eating or using the restroom
