First-aid measures

Inhalation
- Remove to fresh air.
- Oxygen or artificial respiration if needed.
- If symptoms persist, call a physician
Eye contact
- Keep eyelids open to allow evaporation of product.
- Flush eyes with running water for several minutes, while keeping the eyelids wide open.
- If eye irritation persists, consult a specialist.
Skin contact
- Allow to evaporate.
- Rinse with lukewarm running water.
- If symptoms persist, call a physician.
Ingestion is not a route of exposure.

Fire-fighting measures

Suitable extinguishing media
- powder
- Carbon dioxide (CO2)
Extinguishing media which must not be used for safety reasons
- Never use water.
Special exposure hazards in a fire
- Extremely flammable.
- Vapours may form explosive mixtures with air.
- Heating can release hazardous gases.
- Gas/vapours are heavier than air and so may travel along the ground; remote ignition possible.
- Possible dangerous polymerization.
Special protective equipment for fire-fighters
- Evacuate personnel to safe areas.
- Intervention only by capable personnel who are trained and aware of the hazards of the product.
- Wear self-contained breathing apparatus and protective suit.
- Fire fighters must wear fire resistant personnel protective equipment.
- Wear chemical resistant oversuit
- Protect intervention team with a water spray as they approach the fire.
- Clean contaminated surface thoroughly.
Other information
- If safe to do so, remove the exposed containers, or cool with large quantities of water.
- Approach from upwind.
- Use a explosimeter/gas detector/oxygen analyser to determine the area of danger.
- Depending on wind direction, warn people of the danger of intoxication, close doors and windows,and switch off the ventilation.
- Evacuate personnel to safe areas.
- Never try to extinguish a leak of burning gas which cannot be stopped or controlled.
- Avoid spraying the leak source.
- After the fire, proceed rapidly to clean the surfaces exposed to the fumes in order to limit the damage to the equipment.
- As for any fire, ventilate and clean the rooms before re-entry.

Accidental release measures

Personal precautions
- Refer to protective measures listed in sections 7 and 8.
- Isolate the area.
- Keep away from open flames, hot surfaces and sources of ignition.
- Keep away from incompatible products
- Approach from upwind.
- Ventilate the area.
- Prevent further leakage or spillage if safe to do so.
Environmental precautions
- Should not be released into the environment.
Methods for cleaning up
- Allow to evaporate.
- Prevent product from entering drains.

Handling and storage

Handling

Exposure controls / personal protection

Exposure Limit Values
US ACGIH Threshold Limit Values TWA = 500 ppm
Exposure controls
- Ensure adequate ventilation.
- Refer to protective measures listed in sections 7 and 8.
- Apply technical measures to comply with the occupational exposure limits.
Occupational exposure controls
Respitoryatory protection
- In case of insufficient ventilation, wear suitable respiratory equipment.
-Self-contained breathing apparatus in mediumconfinement/insufficient oxygen/in case of large uncontrolled emissions/in all circumstances when the mask and cartridge do not give adequate protection.
- In the case of hazardous fumes, wear self contained breathing apparatus.
- Use only respiratory protection that conforms to international/ national standards.
Hand protection
- Wear suitable gloves.
