Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide. Prevent contamination of water sources.
Unsuitable Extinguishing Media: Avoid water jets that might spread the fire.
Special Hazards Arising from Substance: Vapors can form explosive mixtures with air. Hazardous gases such as carbon monoxide, carbon dioxide can form during combustion.
Advice for Firefighters: Wear self-contained breathing apparatus and full protective gear. Cool exposed containers with water spray to prevent pressure build-up and possible violent rupture.
Fire/Explosion Hazards: Containers may explode from pressure buildup. Flashback possible along vapor trail.
Personal Precautions: Evacuate non-essential personnel. Avoid breathing vapors; ventilate enclosed areas. Wear appropriate protective equipment.
Environmental Precautions: Prevent entry into sewers or waterways. Contain spills to prevent contamination.
Methods for Cleanup: Absorb spill with inert material (sand, earth, vermiculite). Collect into a suitable container for disposal. Wash contaminated area after material pickup.
Recommendations for Safe Handling of Spillages: Remove all ignition sources, ground and bond all equipment.
Reference to Other Sections: For personal protection, see Exposure Controls and Personal Protection Section.
Handling: Use only in well-ventilated areas. Avoid breathing vapors, avoid skin and eye contact. Keep away from open flames, hot surfaces, and sources of ignition.
Storage: Store in a tightly sealed original container in a cool, dry, and well-ventilated place. Keep away from incompatible materials like strong oxidizers, acids, and bases. Store away from food and drink.
Specific End Uses: Industrial solvent and chemical intermediate — not for consumer use.
Storage Temperature: Recommended below 30°C, do not freeze.
Incompatible Materials: Strong acids, alkalis, oxidizing agents, reducing agents.
Engineering Controls: Provide local exhaust ventilation to minimize exposure. Use closed systems or enclosures to prevent vapor release.
Personal Protective Equipment: Suitable chemical resistant gloves (nitrile, neoprene), safety goggles or face shield, protective clothing. Use NIOSH-approved respirator if vapors are generated.
Exposure Limits: No established OSHA or ACGIH exposure limits for this compound. Monitor workplace air for significant levels.
