First-aid measures
General information:
When in doubt or if symptoms are observed, get medical advice.
Never give anything by mouth to an unconscious person or a person with cramps.
If unconscious place in recovery position and seek medical advice
After inhalation:
Remove casualty to fresh air and keep warm and at rest.
If breathing is irregular or stopped, administer artificial respiration.
After contact with skin:
Immediately remove any contaminated clothing, shoes or stockings.
After contact with skin, wash immediately with plenty of water and soap.
Do not wash with: Solvents/Thinner
After contact with eyes:
In case of contact with eyes flush immediately with plenty of flowing water for 10 to 15 minutes holding eyelids apart and consult an ophthalmologist. Remove contact lenses, if present and easy to do.
Continue rinsing. Seek medical advice immediately.
After ingestion:
If swallowed, rinse mouth with water (only if the person is conscious).
Call a physician immediately.
Put victim at rest, cover with a blanket and keep warm.
Do not induce vomiting.

Fire-fighting measures
1. Extinguishing media
- Suitable extinguishing media: Carbon dioxide (CO2), Dry extinguishing powder, Water spray
- Unsuitable extinguishing media: Full water jet
2. Special hazards arising from the substance or mixture
- Can be released in case of fire: Carbon monoxide. Sulphur dioxide (SO2). Nitrogen oxides (NOx)
- Do not inhale explosion and/or combustion gases.
3. Advice for firefighters:
Wear a self-contained breathing apparatus and chemical protective clothing.

Accidental release measures
1. Personal precautions, protective equipment and emergency procedures:
Keep away from sources of ignition. - No smoking. Ventilate affected area.
Avoid breathing dust/fume/gas/mist/vapours/spray.
See protective measures under "Handling and storage" and "Exposure controls/personal protection".
2. Environmental precautions:
Do not allow to enter into surface water or drains.
In case of gas escape or of entry into waterways, soil or drains, inform the responsible authorities.
3. Methods and material for containment and cleaning up:
Prevent spread over a wide area (e.g. by containment or oil barriers). Absorb with liquid-binding material (e.g. sand, diatomaceous earth, acid- or universal binding agents).
Collect in closed and suitable containers for disposal. Disposal: see section "Disposal considerations".
Clean with detergents. Avoid solvent cleaners.
