Dichloro(chloromethyl)methylsilane

Guidance on Safe Use

First-aid measures

General information:

Remove contaminated clothes at once. In case of accident or if you feel unwell seek medical advice immediately (show the label if possible).

Observe self-protection for first aid. Take persons to a safe place. Keep warm, in restful position, cover up.

After inhalation:

Move to fresh air, keep the victim laying down and restful. If breathing has stopped, give artificial respiration.

Seek medical advice and clearly identify substance.

After contact with the skin:

Wash immediately with plenty of water. Remove contaminated clothes at once. In serious cases, use emergency shower immediately.

Seek medical advice and clearly identify substance.

After contact with the eyes:

Rinse immediately with plenty of water for 10-15 minutes and seek medical advice.

Keep eyelids well open to rinse the whole eye surface and eyelids with water.

After swallowing:

Rinse mouth with water. If conscious, give several small portions of water to drink. Do not induce vomiting.

Seek medical advice immediately and produce the label or packaging.

Fire-fighting measures

General information:

Fight fire from a safe distance.

Suitable extinguishing media:

alcohol-resistant foam. For small amounts: carbon dioxide.

Extinguishing media which must not be used for safety reasons:

water.

Special exposure hazards arising from the substance or preparation itself, combustion products, resulting gases:

Hazardous combustion products: hydrogen chloride, silicon dioxide.

Special protective equipment for fire fighting:

Use respiratory protection independent of recirculated air.

Accidental release measures

Personal precautions:

Wear personal protection equipment (see section 8). Task force: Use tightly fitting chemical protection suit (see section 8).

Keep unprotected persons away. Take persons to a safe place. Avoid contact with eyes and skin. Avoid inhaling mists and vapours.

Observe wind direction.

Environmental precautions:

Contain any fluid that runs out using suitable material (e.g. earth). Prevent material from entering sewers or surface waters.

Dispose of in prescribed marked containers. Observe local/state/federal regulations.

Methods for cleaning up:

Absorb with liquid, mainly acid binding material and dispose of according to local/state/federal regulation.

Cover larger quantities by near waterless foam and take up in container. Do not flush away with water.

Further information:

Eliminate all sources of ignition.

Handling and storage

General information:

Avoid exposure by technical measures or personal protective equipment.

Handling:

Precautions for safe handling:

Ensure adequate ventilation. Must be syphoned off in situ. Keep away from incompatible substances in accordance with section 10.2.

Precautions against fire and explosion:

Keep away from sources of ignition and do not smoke. Take precautionary measures against electrostatic charging.

Flammable vapors may accumulate and form explosive mixtures with air in containers, process vessels, including partial, empty and uncleaned

containers and vessels, or other enclosed spaces. Vapours heavier than air, therefore inflammable gas mixture may form mainly near floor.

Cool endangered containers with water.

Storage:

Conditions for storage rooms and vessels:

Do not store in containers made of aluminum or other light metals. Do not store in containers coated with zinc.

Advice for storage of incompatible materials:

Keep away from alkalis.

Further information for storage:

Keep in the original container in a cool well ventilated place. Keep container dry and tightly closed.
