Safety & Health

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
Cleansing 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
Ventilation:
of workshop : deposit in plastic-lined bin
of workplace : Renew air 3 to 5 times an hour Exhaust fans. Operatives should avoid inhaling vapours.

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, Aradur 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.

Storage & Handling

Storage Conditions

Store the components in a dry place at 18-25°C, in tightly sealed original containers. Under these conditions, the shelf life will correspond to the expiry date stated on the label. After this date, the product may be processed only after reanalysis. Partly emptied containers should be tightly closed immediately after use. For information on waste disposal and hazardous products of decomposition in the event of a fire, refer to the Material Safety Data Sheets (MSDS) for these particular products.
