Trichloro(phenyl)silane

Guidance on Safe Use

First-aid measures

General information:

Take persons to a safe place. Observe self-protection for first aid. Always seek medical advice

in the event of contact with this substance.

After inhalation

Keep the patient calm. If unconscious place in stable sideways position. Protect against loss

of body heat. If breathing stops, administer artificial respiration. Seek medical advice

immediately and clearly identify substance.

After contact with the skin

Remove contaminated clothes at once. Wash off with plenty of water or water and soap

immediately for 10-15 minutes. In serious cases, use emergency shower immediately. Seek medical

advice immediately and clearly identify substance.

After contact with the eyes

Rinse immediately with plenty of water for 10-15 minutes. Keep eyelids well open to rinse the

whole eye surface and eyelids with water. Seek medical advice immediately and clearly identify

substance. Continue to bathe eyes during transport to medical practitioner.

After swallowing

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

medical advice immediately and clearly identify substance.

Advice for the physician

After inhalation: treat as early as possible using cortisone spray. Medical checks necessary up

to a latency period of at least 24 hours. In the event of 1st degree burns use corticoidexterna.

In the case of 2nd degree burns, use symptomatic treatment. Risk of intra-abdominal

gas developing if swallowed. Risk of perforation of the stomach.

Fire-fighting measures

Suitable extinguishing media

alcohol-resistant foam , carbon dioxide , dry sand . Application of foam will release at least

initially significant amounts of flammable and corrosive vapors. These vapors could be trapped

under the foam blanket.

Extinguishing media which must not be used for safety reasons

water , extinguishing powder , halones .

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

resulting gases

Hazardous combustion products: hydrogen chloride .

Special protective equipment for fire fighting

Use respiratory protection independent of recirculated air. Use tightly fitting chemical

protection suit (see section 8).

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. Avoid contact with eyes and

skin. Avoid inhaling mists and vapours. Do not walk through spilled material. Ensure adequate

ventilation. If material is released indicate risk of slipping.

Environmental precautions

Prevent material from entering surface waters, drains or sewers and soil. Contain any fluid

that runs out using suitable material (e.g. earth). Condense gasses/vapours/mists using a

directed spray of water. Retain contaminated water/extinguishing water. Dispose of in

prescribed marked containers. For large amounts: Close leak if possible without risk.

Methods for cleaning up

Do not flush away with water. For small amounts: 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. Exhaust vapours. Clean up with plenty of water.

Further information:

Eliminate all sources of ignition.

Handling and storage

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. Spilled substance increases risk of slipping.

Precautions against fire and explosion:

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.

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

electrostatic charging. Cool endangered containers with water.

Storage

Conditions for storage rooms and vessels:

Store under protective gas.

Advice for storage of incompatible materials:

not applicable

Further information for storage:

Protect against moisture. Store in original container only. Keep container tightly closed and

store in a cool, well ventilated place.

Disposal considerations

Material

Recommendation:

Dispose of according to regulations by incineration in a special waste incinerator. Observe

local/state/federal regulations. Ensure special chem./phys. treatment after discussion with the

supplier.
