Safety & Health

Industrial Hygiene

Mandatory and recommended industrial hygiene procedures should be followed when-ever our products are being handled and processed. For additional information please consult the corresponding Safety Data Sheets and the brochure "Hygienic precautions for handling plastics products”.

First Aid

Contamination of the eyes by resin, hardener or casting 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

Safety precautions at workplace:    
protective clothing : yes
gloves : essential
arm protectors : recommended when skin contact likely
goggles/safety glasses : yes
respirator/dust mask : recommended
Skin protection    
before starting work : Apply barrier cream to exposed skin
after washing : Apply barrier or nourishing cream
Cleaning of contaminated skin : Dab off with absorbent paper, wash with warm water and alkali-free soap, then dry with disposable towels. Do not use solvents
Clean shop requirements : Cover workbenches, etc. with light coloured paper. Use disposable beakers, etc.
Disposal of spillage : Soak up with sawdust or cotton waste and deposit in plastic-lined bin
Ventilation:    
of workshop : Renew air 3 to 5 times an hour
of workplace : Exhaust fans. Operatives should avoid inhaling vapors.

Storage & Handling

Storage Conditions

The components have to be stored in tightly sealed and dry original containers according to the storage conditions on the product label. Under these conditions, the shelf life will correspond to the expiration date stated on the label. After this date, the product may be processed only following reanalysis. Partly emptied containers should be closed tightly immediately after use.

For information on waste disposal and hazardous products of decomposition in the event of fire, refer to the Material Safety Data Sheets (MSDS) for these particular products.
