Eye Contact: Immediately flush with plenty of water for at least 15 minutes. Remove contact lenses if possible. Seek medical attention right away.
Skin Contact: Remove contaminated clothing. Wash affected skin with soap and water for minimum 15 minutes. Get medical help if irritation remains.
Inhalation: Move person to fresh air. If breathing is difficult or symptoms persist, get medical assistance as soon as possible.
Ingestion: Rinse mouth. Do not induce vomiting. Call a poison center or doctor. Never give anything by mouth to an unconscious person.
Serious Exposure: Immediate medical attention is critical in case of breathing problems, large area exposure, or persistent symptoms.
Notes for Doctor: Treat symptomatically; maintain airway and monitor vital signs.
Extinguishing Media: Use alcohol-resistant foam, dry chemical, carbon dioxide, or water spray. Avoid strong water jets that could spread material.
Hazards from Combustion: Produces irritating or toxic fumes (carbon monoxide, carbon dioxide, phenolics) when burned.
Specific Hazards: Vapors may form explosive mixtures with air in confined spaces.
Special Protective Equipment: Firefighters must wear self-contained breathing apparatus and full protective suit.
Firefighting Instructions: Keep containers cool with water spray, move containers from fire area if safe, avoid inhaling combustion gases.
Explosion Protection: Avoid ignition sources, static discharge, sparks.
Personal Precautions: Evacuate area, ventilate space, ensure suitable protective equipment (gloves, goggles, respirator) is worn.
Environmental Precautions: Prevent further leakage or spillage if safe, keep substance away from drains, waterways, soil.
Cleanup Methods: Contain and collect spill with inert absorbent (sand, vermiculite), transfer to proper waste containers. Afterward, clean floor with water.
Incident Reporting: Notify appropriate authorities as required by national and local regulations.
Safe Handling: Use within well-ventilated locations, avoid skin and eye contact, keep away from open flames and high heat.
Hygiene Measures: Thoroughly wash hands and skin after use. Contaminated clothing must be removed and cleaned before reuse.
Storage Requirements: Store tightly closed in original containers, in cool, dry, ventilated areas.
Incompatibles: Keep away from acids, oxidizers, strong bases, or any reactive compounds.
Special Storage Rules: Store away from food and drink. Label chemical storage areas clearly.
Exposure Limits: ACGIH TLV: 10 ppm, OSHA PEL: Not established (use best industrial hygiene practices).
Engineering Controls: Use fume hoods, process enclosures, local exhaust to minimize vapor build-up.
Personal Protective Equipment: Nitrile or neoprene gloves, chemical-resistant goggles, face shield for splash risk, long-sleeve lab coat.
Respiratory Protection: Half-mask respirator with organic vapor cartridges where ventilation cannot keep vapor at safe levels.
