After skin contact
When in contact with the skin, clean with soap and water. If skin problems persist, seek medical advice.
After eye contact
In case of contact with eyes rinse thoroughly with plenty of water and seek medical advice.
After ingestion
When swallowed accidentally, do not induce vomiting, get medical help.
Advice to doctor
Hazards
Danger of irritation of the lungs
Treatment
In case of lung irritation, treat first with Auxiloson i.e. Pulmicort - Dosing aerosol (Auxiloson and Pulmicort
are registered Trade Marks). Treat symptomatically
5.) Fire-fighting measures
Suitable extinguishing media
Foam; Dry powder; Carbon dioxide; Water spray jet
Extinguishing media that must not be used for safety reasons
strong water jet
Special exposure hazards arising from the substance or preparation itself, its combustion products or
from resulting gases
In case of fires, hazardous combustion gases are formed: Carbon monoxide (CO). Carbon dioxide (CO2);
Combustion gases of organic materials must in principle be graded as inhalation poisons.
Special protective equipment for firefighting
Use self-contained breathing apparatus.
Other information (chapter 5.)
Cool endangered environment with water spray jet.
6.) Accidental release measures
Personal precautions
Avoid contact with eyes and skin.
Environmental precautions
Prevent spread over a wide area (e.g. by containment or oil barriers). Do not discharge into the
drains/surface waters/groundwater.
Methods for cleaning up/taking up
Pick up with absorbent material (eg sand, kieselgur, acid binder, universal binder, sawdust). Dispose of
contaminated material as prescribed
7.) Handling and storage
Handling
Advice on safe handling
Provide good ventilation of working area (local exhaust ventilation if necessary).
Advice on protection against fire and explosion
Keep away from sources of ignition - refrain from smoking. Take precautionary measures against static
charges. Emergency cooling must be provided for the eventuality of a fire in the vicinity.
