First-aid measures
- Inhalation: Remove person to fresh air and keep comfortable for breathing. Call a physician or poison control centre immediately.
- Skin contact: Take off immediately all contaminated clothing and wash it before reuse. Wash off immediately with plenty of water. Call a physician or poison control centre immediately.
- Eye contact: Immediately flush eye(s) with plenty of water. Take victim immediately to hospital. Continue rinsing eyes during transport to hospital. Remove contact lenses, if present and easy to do. Continue rinsing.
- Ingestion: Rinse mouth with water. Do NOT induce vomiting. Call a POISON CENTER /doctor.
- Inhalation: Inhalation of vapours may cause mild irritation to the mucous membrane. May cause respiratory irritation.
- Skin contact: Causes skin burns. May cause an allergic skin reaction.
- Eye contact: Causes serious eye damage.
- Ingestion: Harmful if swallowed. Ingestion may cause irritation to mucous membranes.
Description of first aid measures:
Most important symptoms and effects:
Fire-fighting measures
Combustible liquid.
Suitable extinguishing media: Product is compatible with standard fire-fighting agents.
Special hazards arising from the substance or mixture: No hazards to be specially mentioned
Advice for firefighters: Wear full protective clothing and self-contained breathing apparatus. Do not allow run-off from fire fighting to enter drains or water courses.
Accidental release measures
- Avoid breathing mist or vapours.
- Avoid contact with skin, eyes and clothing.
- Use personal protective equipment.
- Follow safe handling advice and personal protective equipment recommendations.
