Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical powder, carbon dioxide, water spray (avoid direct jet)
Unsuitable Media: Do not use direct water jet as it may spread material
Specific Hazards: Generates toxic fumes such as oxides of sulfur and carbon under fire conditions
Protective Equipment: Firefighters should use self-contained breathing apparatus, wear full protective clothing
Special Procedures: Cool closed containers with water spray to prevent pressure build-up and rupture, evacuate area of unprotected personnel
Personal Precautions: Wear appropriate protective equipment—chemical resistant gloves, goggles, boots, and clothing
Environmental Precautions: Prevent spillage from entering watercourses, drains or soil, report spills to local authorities
Cleanup Methods: Contain spilled material with sand, earth, or inert absorbent, collect and place in containers for proper disposal, wash area with large amounts of water after initial pick-up, ventilate the area thoroughly
Disposal: Dispose of waste material through licensed waste handlers, minimize further release into environment
Handling: Use only in well-ventilated areas, avoid inhalation of vapors, avoid direct contact with skin, eyes, and clothing, do not eat, drink or smoke while using
Safe Practices: Wash hands and face after handling, keep containers tightly closed when not in use
Storage: Store away from incompatible substances (alkalis, oxidizers, strong bases), maintain in cool, dry, well-ventilated space, keep container upright and tightly sealed, do not store in containers made of aluminum, copper, zinc or their alloys, away from direct sunlight and heat sources
Occupational Exposure Limits: No specific OSHA or ACGIH limits established, handle as strong acid
Engineering Controls: Use local exhaust ventilation or other measures to reduce airborne levels, provide eyewash facilities and safety showers
Personal Protective Equipment: Chemical splash goggles or face shield, acid-resistant gloves (nitrile or neoprene), long-sleeved garment or apron, chemical resistant footwear
Respiratory Protection: In case of inadequate ventilation or aerosol formation, wear approved respirators (NIOSH/MSHA) for acid mists
Hygiene Measures: Do not eat or smoke during use, wash hands before breaks and after handling, change contaminated clothing promptly
