First-aid measures

General information:
In case of accident or if you feel unwell seek medical advice (show label or SDS where possible).
After contact with the eyes:
Rinse immediately with plenty of water. Seek medical advice in case of continuous irritation.
After contact with the skin:
Wash with plenty of water or water and soap. In the event of a visible skin change or other complaints, seek medical advice (show
label or SDS where possible).
After inhalation:
Provide fresh air.
After swallowing:
Give several small portions of water to drink. Do not induce vomiting.
Most important symptoms and effects, both acute and delayed
Any relevant information can be found in other parts of this section.
Indication of any immediate medical attention and special treatment needed
Further toxicology information must be observed.

Fire-fighting measures

Extinguishing media
Suitable extinguishing media:
water mist , extinguishing powder , alcohol-resistant foam , carbon dioxide , sand .
Extinguishing media which must not be used for safety reasons:
water jet .
Special hazards arising from the substance or mixture
Risk of hazardous gasses or fumes in the event of fire. Exposure to combustion products may be a health hazard! Hazardous
combustion products: carbon oxides , silicon oxides , incompletely burnt hydrocarbons , toxic and very toxic fumes .
Advice for firefighters
Special protective equipment for fire fighting:
Use respiratory protection independent of recirculated air. Keep unprotected persons away.

Accidental release measures

Personal precautions, protective equipment and emergency procedures
Secure the area. Wear personal protection equipment. Keep unprotected persons away. If material is released
indicate risk of slipping. Do not walk through spilled material.
Environmental precautions
Prevent material from entering surface waters, drains or sewers and soil. Close leak if possible without risk. 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. Inform authorities if substance leaks into
surface waters, sewerage or ground.
Methods and material for containment and cleaning up
Take up mechanically and dispose of according to local/state/federal regulations. Do not flush away with water. For small
amounts: Absorb with a neutral (non-acidic / non-basic) liquid binding material such as diatomaceous earth and dispose of
according to government regulations. For large amounts: Liquids may be recovered using suction devices or pumps. If flammable,
only air driven or properly rated electrical equipment should be used. Clean any slippery coating that remains using a detergent /
soap solution or another biodegradable cleaner. Silicone fluids are slippery; spills are a safety hazard. Apply sand or other inert
granular material to improve traction.
Further information:
Exhaust vapours. Eliminate all sources of ignition. Consider explosion protection.
Reference to other sections
Relevant information in other sections has to be considered. This applies in particular for information given on personal protective
equipment and on disposal.

Handling and storage

Precautions for safe handling:
Avoid formation of aerosols. In case of aerosol formation special protective measures are required (exhausting by suction,
respiratory protection). 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. Keep away from sources of ignition and do not smoke. Take
precautionary measures against electrostatic charging. Cool endangered containers with water.
Conditions for storage rooms and vessels:
Observe local/state/federal regulations.
Advice for storage of incompatible materials:
Observe local/state/federal regulations.
Further information for storage:
Store in a dry and cool place. Store container in a well ventilated place.

Exposure controls / personal protection

Control parameters
Maximum airborne concentrations at the workplace:

Aerosol - inhalable fraction 10,0 mg/m3
CAS No. 108-88-3 Toluene AGW 190,0 mg/m3 50,0 ppm

The aerosol limit specified is a recommendation should aerosol be formed during processing.
Toluene (CAS no. 108-88-3): Refer to Technical Rules for Hazardous Substances "TRGS 900" for more details on the German
AGW.

Further information:
Maximum concentration at workplace recommended by producer: octamethylcyclotetrasiloxane (D4, CAS no. 556-67-2) = 10 ppm
(123 mg/m3).

Exposure in the work place limited and controlled
General protection and hygiene measures:
Observe standard industrial hygiene practices for the handling of chemical substances. Do not eat, drink or smoke when handling.
Personal protection equipment:
Respiratory protection
No personal respiratory protective equipment normally required.
In case of mist, spray or aerosol exposure wear suitable personal respiratory protection and protective suit. Suitable respiratory
equipment: Filtering half-face mask, according to acknowledged standards such as EN 149.
Recommended Filter type: FFP1 or equivalent filter, according to acknowledged standards such as EN 149
Observe the equipment manufacturer's information and wear time limits for respirators.
Eye protection
Recommendation: protective goggles .
Hand protection
Use of protective gloves is recommended when handling the material.
Recommended glove types: Protective gloves made of nitrile rubber
thickness of the material: > 0,1 mm
Breakthrough time: > 480 min
Recommended glove types: Protective gloves made of butyl rubber
thickness of the material: > 0,3 mm
Breakthrough time: > 480 min
Please observe the instructions regarding permeability and breakthrough time which are provided by the supplier of the gloves.
Also take into consideration the specific local conditions under which the product is used, such as the danger of cuts, abrasion,
and the contact time. Note that, due to the numerous external influences (such as temperature), a chemically resistant protective
glove in daily use may have a service life that is considerably shorter than the measured break through time.
Exposure to the environment limited and controlled
Prevent material from entering surface waters, drains or sewers and soil. Do not introduce large amounts into purification plants.

Stability and reactivity

Reactivity; Chemical stability; Possibility of hazardous reactions
If stored and handled in accordance with standard industrial practices no hazardous reactions are known.
Relevant information can possibly be found in other parts of this section.
Conditions to avoid
Heat, open flames, and other sources of ignition.
Incompatible materials
none known
Hazardous decomposition products
If stored and handled properly: none known . Measurements have shown the formation of small amounts of formaldehyde at

Disposal considerations

Waste treatment methods
Material
Recommendation:
Material that cannot be used, reprocessed or recycled should be disposed of in accordance with Federal, State, and local
regulations at an approved facility. Depending on the regulations, waste treatment methods may include, e.g., landfill or
incineration.
Uncleaned packaging
Recommendation:
Completely discharge containers (no tear drops, no powder rest, scraped carefully). Containers may be recycled or re-used.
Observe local/state/federal regulations. Uncleaned packaging should be treated with the same precautions as the material.
Waste Disposal Legislation Ref.No.(EC)
It is not possible to determine a waste code for this product in accordance with the European Waste Catalogue (EWC) since it is
only possible to classify it according to how it is used by the customer. The waste code is to be determined within the EU in liaison
with the waste-disposal operator.
