First Aid Contamination of eyes by resin, hardener of casting mix should be treated immediately by flushing with clean,running water for 10 to 15minutes, 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 cleaning cream. A doctor should be on the event of severe imitation of burns. Contaminated clothing should be changed immediately. Anyone taken ill after inhaling vapors should be moved out of doorsimmediately,in all case of doubt call for medical assistance. |
