Administrative data

First-aid measures

On contact with eyes : Rinse immediately with plenty of water and seek medical advice.
On skin contact : Rinse immediately with plenty of water for at least 15 minutes. Obtain medical attention.
If inhaled : Remove to fresh air. Obtain medical attention.
On ingestion: Obtain medical attention. Do not induce vomiting.

Fire-fighting measures

Suitable extinguishing media:
On large fires use dry chemical, foam or water spray (fog). On small fires use carbon
dioxide (CO2), dry chemical or water spray. Water can be used to cool fire exposed
containers.
Unsuitable extinguishing media: None known.
Hazards during fire fighting : Vapours may form explosive mixtures with air.
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.
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.

Accidental release measures

Personal precautions: Wear proper protective equipment.
Precautions to protect the environment: Do not empty into drains. Prevent from spreading or entering into drains, ditches or rivers
by using sand, earth or other appropriate barriers. Inform local authorities if this cannot be prevented.
Methods for cleaning up: Determine the need to evacuate or isolate the area according to your local emergency
plan. 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: Local ventilation is required. General ventilation is required. Avoid skin and eye contact.
Do not breathe vapour. Do not ingest.
Advice on storage : Do not store with oxidizing agents. Vapours may form explosive mixtures with air.
Specific uses : Refer to technical data sheet
Unsuitable packaging materials: None known.

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 : Suitable, heavy duty, plastic or rubber gauntlets should be worn: Nitrile rubber. Silver
shield(TM). Viton(TM). Regarding glove's breakthrough time,contact your chemical
protective glove supplier.
Eye protection : Face shield or safety goggles.
Skin protection : Wear impervious overalls in circumstances where significant skin contact can occur.
Hygiene measures : Exercise good industrial hygiene practice. Wash after handling, especially before eating,
drinking or smoking. Remove contaminated clothing immediately.
Environmental exposure controls: Refer to section 6 and 12 of MSDS.
Additional information: These precautions are for room temperature handling. Use at elevated temperature or
aerosol/spray applications may require added precautions. For further information
regarding the use of silicones / organic oils in consumer aerosol applications, please refer
to the guidance document regarding the use of these types of materials in consumer
aerosol applications that has been developed by the silicone industry (www.SEHSC.com)
or contact the Dow Corning customer service group.

Stability and reactivity

Disposal considerations

Product disposal: This material must be disposed of as hazardous waste. 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.
Packaging disposal: Dispose of in accordance with local regulations. Waste codes should be assigned by the
user, preferably in discussion with the waste disposal authorities.
