No special hazards.

The product doesn’t contain substances classified as hazardous to health in concentrations, which should be taken into account according to EC directive. 4. FIRST AID MEASURES

AFTER INHALATION

A person affected by formaldehyde vapour should be moved to fresh air and protected against cold. In case of irritation of respiratory system or mucous membranes, in case of indisposition or prolonged exposure, seek medical advice. AFTER INGESTION

No special action is necessary. AFTER SKIN CONTACT

In case of burns caused by melted resin, seek medical advice. AFTER EYE CONTACT

Rinse immediately with plenty of water. In case of eye irritation, seek medical advice. FIRST-AID MEASURES

A person exposed to breathing in vapour of poliacetal decomposition products during processing should be evacuated from the contaminated area, supplied with fresh air and protected against cold.

5. FIRE-FIGHTING MEASURES SUITABLE EXTINGUISHING MEDIA water, foam, dry powder, carbon dioxide

EXTINGUISHING MEDIA WHICH SHALL NOT BE USED FOR SAFETY REASONS Lack

SPECIAL EXPOSURE HAZARDS ARISING FROM THE SUBSTANCE / PREPARATION ITSELF

Thermal decomposition or burning may release formaldehyde, oxides of carbon and other toxic gases or vapours. Do not release chemically contaminated water into drains, soil or surface waters. Sufficient measures must be taken to retain water used for extinguish. Dispose of contaminated water and soil according to local regulations.

Special protective equipment for persons extinguishing the fire: an air-light breathing apparatus should be used.

SPECIAL PROTECTIVE EQUIPMENT FOR FIRE-FIGHTERS Use self-contained breathing apparatus. Non-suitable extinguishing agents: none. 6. ACCIDENTAL RELEASE MEASURES

PERSONAL PRECAUTIONS not required

ENVIRONMENTAL PRECAUTIONS not required

METHODS FOR CLEANING UP

For small amounts: pick up with suitable appliance and dispose of. For large amounts: pick up with suitable appliance and dispose of. ADDITIONAL ADVICE

High risk of slipping due to leakage/spillage of product 7. HANDLING AND STORAGE

7.1. HANDLING

If the thermal resistance of the product is exceeded (the products is overheated), gaseous products (monomer and other decomposition products) may be released.

Breathing in vapour should be avoided and dust generation should be restricted.

The processing equipment should be furnished with appropriate ventilation equipment. Fire and explosion protection:

In case of using appropriate processing techniques no additional safety measures are

necessary.

The storage containers should be grounded in order to avoid generation of static electricity. 7.2. STORAGE

The products should be stored in dry rooms. 7.3. SPECIFIC USE(S)
