Safety & Health

First Aid

Contamination of the eyes by resin, hardener or mix should be treated immediately by flushing with clean, running water for 10 to 15 minutes. A doctor should then be consulted. Material smeared or splashed on the skin should be dabbed off, and the contaminated area then washed and treated with a cleansing cream (see above). A doctor should be consulted in the event of severe irritation or burns. Contaminated clothing should be changed immediately. Anyone taken ill after inhaling vapours should be moved out of doors immediately. In all cases of doubt call for medical assistance.

Handling Precautions

Personal hygiene
Safety precautions at workplace
protective clothing : yes
gloves : essential
arm protectors : recommended when skin contact likely
goggles/safety glasses : yes
Skin protection
before starting work : Apply barrier cream to exposed skin
