Special Protection Information

Respiratory Protection: Adequate ventilation must be provided. If above the NOHSC exposure standard, use SA approved respiratory protective equipment. If dust is generated during cutting or machining/grinding/sanding of cured product, wear disposable dust mask (Type P1). or better as determined by you risk assessment. When using resin system (including hardener) with fibres, use combination mask with vapour and dust particle filter.

Eye Protection:Use SA approved chemical splash goggles.

Protective Clothing:Wear chemical resistant gloves such as butyl rubber or neoprene rubber gloves. Apply full dermal protection to un-covered skin. Wear full length trousers and long sleeved shirts and safety boots.

CONSULT SAFETY EQUIPMENT SUPPLIERS FOR RECOMMENDATIONS.

Effects of Exposure

Eyes:May cause irritation and redness.
Inhalation:May cause irritation of the respiratory tract. Isocyanates are known to cause sensitisation of the respiratory tract.
Skin:Prolonged and/or frequent contact can result in irritation of the skin.
Swallowing:May cause some gastrointestinal irritation.

Spill or Leak Procedures

Eliminate all sources of ignition and ventilate area. Wearing protective equipment, stop spill at source, dam area and if possible pump liquid into salvage tank. Alternatively, absorb residue with vermiculite or sand. Scoop up using non-sparking tools into labelled waste container. Flush area with water, but prevent it from entering waterways. Dispose of waste in accordance with local, state and federal regulations. Reporting of spills/leaks may be required under EPA and Dangerous Goods regulations.

Fire Extinguishing Procedures

Wear protective clothing and equipment including self-contained breathing equipment. In general, use foam or carbon dioxide to put out fires. (Refer to MSDS). Cool fire exposed containers with water spray.

Storage and Handling Procedures

DG Class 3 (Flammable liquid). Store in properly closed, labelled containers in a cool area, fitted with floor level and breathing zone ventilation to remove vapours which collect at these levels. Ensure all sources of ignition are eliminated. Keep away from strong oxidising agents. Do not transfer to unmarked containers. Do not transfer to unapproved plastic containers. Earth containers when pouring to prevent the discharge of static electricity.
