First-aid measures

On contact with eyes : No first aid should be needed.
On skin contact : No first aid should be needed.
If inhaled : No first aid should be needed.
On ingestion : No first aid should be needed.

Fire-fighting measures

Suitable extinguishing media : On large fires use AFFF alcohol compatible foam or water spray (fog). On small fires use
AFFF alcohol compatible foam, CO2 or water spray (fog). Water can be used to cool fire exposed containers.
Unsuitable extinguishing media : None known.
Hazards during fire fighting : Fire burns more vigorously than would be expected. Vapours are heavier than air and can
travel along ground to remote ignition sources. Electrostatic charges may be generated during transfer of product from its container. Ensure that all equipment is electrically earthed. Vapours may form explosive mixtures with air.
Hazardous Combustion Products : Thermal breakdown of this product during fire or very high heat conditions may evolve the following decomposition products: Silica. Carbon oxides and traces of incompletely burned carbon compounds. Formaldehyde.
Special protective equipment/procedures : A self-contained respirator and protective clothing should be worn. Determine the need to
evacuate or isolate the area according to your local emergency plan. Use water spray to keep fire exposed containers cool.

Accidental release measures

Personal precautions, protective equipment and emergency procedures : A self-contained respirator and protective clothing should be worn. Determine the need to evacuate or isolate the area according to your local emergency plan. Eliminate all possible sources of ignition.
Environmental precautions : Prevent from spreading or entering into drains, ditches or rivers by using sand, earth or other appropriate barriers.
Methods and materials for containment and cleaning up : Determine the need to evacuate or isolate the area according to your local emergency plan.
Eliminate all possible sources of ignition. Very large spills should be contained by bunding, etc... procedures. Mop, wipe or soak up with absorbent material and place in a container with a lid. The spilled product produces an extremely slippery surface.

Handling and storage

Advice on safe handling : General ventilation is required. Local ventilation is recommended. Avoid eye contact. Do not breathe vapour. Do not empty into drains.
Advice on storage : Store in a flameproof, well ventilated area. Electrostatic charges may be generated during transfer of product from its container. Ensure that all equipment is electrically earthed. Keep container tightly closed.
Vapours may form explosive mixtures with air. Storage temperature: minimum -20 °C, maximum 50 °C

Exposure controls / personal protection

Engineering Controls : Ventilation : Local Exhaust ventilation required
Personal protection equipment:
Respiratory protection : Suitable respiratory protection should be worn if the product is used in large quantities, confined spaces or in other circumstances where the OEL may be approached or exceeded. Depending on the working conditions, wear a respiratory mask with filter(s) AX or use a self-contained respirator. The choice of a filter type depends on the amount and type of chemical being handled in the workplace. Regarding filter characteristics, contact your respiratory protection supplier.
Hand protection : Gloves are not normally required.
Eye/face protection : Safety goggles should be worn.
Skin protection : Protective equipment is not normally necessary.
Hygiene measures : Exercise good industrial hygiene practice. Wash after handling, especially before eating,
drinking or smoking.

Stability and reactivity

Reactivity : None known.
Stability : Stable under normal usage conditions.
Possibility of hazardous reactions : None known.
Conditions to avoid : Eliminate all possible sources of ignition.
Materials to avoid : Can react with strong oxidising agents.
Hazardous decomposition products : Thermal breakdown of this product during fire or very high heat conditions may evolve
the following decomposition products: Silica. Carbon oxides and traces of incompletely burned carbon compounds. Formaldehyde.

Disposal considerations

Dispose of in accordance with local regulations. According to the European Waste
Catalogue, Waste Codes are not product specific, but application specific. Waste codes
should be assigned by the user, preferably in discussion with the waste disposal
authorities.
