SDS

Eliminate all ignition sources (no smoking, flares, sparks, or flames in immediate area). Keep
combustibles (wood, paper, oil, etc.) away from spilled material. The product is immiscible with
water and will sediment in water systems. Prevent product from entering drains.
Large Spills: Stop the flow of material, if this is without risk. Dike the spilled material, where this is
possible. Use a non-combustible material like vermiculite, sand or earth to soak up the product
and place into a container for later disposal. Following product recovery, flush area with water.
Small Spills: Absorb with earth, sand or other non-combustible material and transfer to containers
for later disposal. Wipe up with absorbent material (e.g. cloth, fleece). Clean surface thoroughly to
remove residual contamination.
Never return spills to original containers for re-use. For waste disposal, see section 13 of the SDS.
Methods and materials for
containment and cleaning up
Avoid release to the environment. Inform appropriate managerial or supervisory personnel of all
environmental releases. Prevent further leakage or spillage if safe to do so. Avoid discharge into
drains, water courses or onto the ground.
Environmental precautions
7. Handling and storage
Obtain special instructions before use. Do not handle until all safety precautions have been read
and understood. Keep away from open flames, hot surfaces and sources of ignition. When using
do not smoke. Do not breathe mist/vapors. Avoid contact with eyes, skin, and clothing. Avoid
prolonged exposure. Pregnant or breastfeeding women must not handle this product. Should be
handled in closed systems, if possible. Provide adequate ventilation. Wear appropriate personal
protective equipment. Avoid release to the environment. Observe good industrial hygiene
practices.
Precautions for safe handling
Store locked up. Keep away from heat, sparks and open flame. Store in a cool, dry place out of
direct sunlight. Store in tightly closed container. Store in a well-ventilated place. Keep in an area
equipped with sprinklers. Store away from incompatible materials (see Section 10 of the SDS).

8. Exposure controls/personal protection
Occupational exposure limits
US. Workplace Environmental Exposure Level (WEEL) Guides
ValueComponents Type
TWA 10 ppmOctamethylcyclotetrasiloxan
e
(CAS 556-67-2)
No biological exposure limits noted for the ingredient(s).
Biological limit values
Good general ventilation should be used. Ventilation rates should be matched to conditions. If
applicable, use process enclosures, local exhaust ventilation, or other engineering controls to
maintain airborne levels below recommended exposure limits. If exposure limits have not been
established, maintain airborne levels to an acceptable level. Provide eyewash station and safety
shower.
Appropriate engineering
controls
Individual protection measures, such as personal protective equipment
Wear safety glasses with side shields (or goggles).
Eye/face protection
Skin protection
Wear appropriate chemical resistant gloves.
Hand protection
Skin protection
Wear appropriate chemical resistant clothing. Use of an impervious apron is recommended.
Other
If engineering controls do not maintain airborne concentrations below recommended exposure
limits (where applicable) or to an acceptable level (in countries where exposure limits have not
been established), an approved respirator must be worn. Appropriate respirator selection should
be made by a qualified professional.
Respiratory protection
Wear appropriate thermal protective clothing, when necessary.
Thermal hazards
Observe any medical surveillance requirements. When using do not smoke. Always observe good
personal hygiene measures, such as washing after handling the material and before eating,
drinking, and/or smoking. Routinely wash work clothing and protective equipment to remove
contaminants. Contaminated work clothing should not be allowed out of the workplace.
