Inhalation: Move person to fresh air if exposed to high vapor levels; seek medical attention if symptoms like cough or dizziness develop
Skin Contact: Remove contaminated clothing; wash well with soap and water; get advice if irritation continues
Eye Contact: Rinse cautiously with water for several minutes, removing contact lenses if present, and continue rinsing until discomfort eases
Ingestion: Rinse mouth, do not induce vomiting, and get medical help if any discomfort or symptoms develop
Most Important Symptoms and Effects: Eye and mild skin irritation, headache with high inhalation, unlikely to cause life-threatening effects
Flammability: Low fire hazard, not easily ignited under normal conditions
Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry powder, carbon dioxide
Unsuitable Media: Direct stream of water may scatter liquid
Hazardous Combustion Products: Carbon monoxide, carbon dioxide released in a fire
Protective Equipment: Firefighters wear self-contained breathing apparatus and full protective gear to avoid inhaling gases or combustion products
Additional Info: Cool closed containers under fire exposure and contain runoff to prevent entry into the environment
Personal Precautions: Avoid breathing vapor or mist, ventilate area, wear protective clothing including gloves and eye protection
Environmental Precautions: Prevent further spillage or leakage, do not allow material to enter watercourses
Methods for Cleanup: Absorb with inert material (sand, earth, vermiculite), transfer to suitable container for disposal
Spill Response: Wash contaminated surface with water after initial cleanup, ensure proper ventilation
Handling: Wear appropriate personal protection to avoid eye and skin contact, use only in well-ventilated areas to minimize vapor build-up, wash hands after use and remove contaminated clothing
Storage: Store in closed, labeled containers in cool, dry, well-ventilated area away from incompatible substances like strong acids or oxidizers, keep away from heat and direct sunlight
Incompatible Materials: Strong acids, bases, and oxidizing agents
Hygiene Measures: Do not eat, drink, or smoke while using this product, always wash thoroughly after handling
Occupational Exposure Limits: No specific value assigned in most jurisdictions, general limit for nuisance dust or vapor may apply (check local regulations)
Engineering Controls: Use adequate ventilation or local exhaust to maintain exposure levels
Personal Protection: Wear chemical-resistant gloves (nitrile or neoprene), splash-proof goggles, and, if exposure risk exists, long sleeves and pants
Respiratory Protection: Use an approved respirator if ventilation is not enough and vapor concentrations rise
Environmental Exposure: Use containment measures to avoid environmental release during use or waste disposal
