Administrative data
First-aid measures
4.1. Description of first aid measures
Remove contaminated clothing. First aid personnel should pay attention to their own safety.
If inhaled:
Keep patient calm, remove to fresh air, seek medical attention. If breathing difficulties develop, aid in breathing and seek immediate medical attention.
On skin contact:
Immediately wash thoroughly with plenty of water, apply sterile dressings, consult a skin specialist.
On contact with eyes:
In case of contact with the eyes, rinse immediately for at least 15 minutes with plenty of water. Immediate medical attention required.
On ingestion:
Rinse mouth immediately and then drink plenty of water, seek medical attention.
4.2. Most important symptoms and effects, both acute and delayed
Symptoms: Eye irritation, dazed state, nausea, skin corrosion, headache, giddiness, irritation of respiratory tract, Further symptoms are possible
4.3. Indication of any immediate medical attention and special treatment needed
Treatment: Treat according to symptoms (decontamination, vital functions), no known specific antidote.
Fire-fighting measures
5.1. Extinguishing media
Suitable extinguishing media:
dry powder, Dry sand, dry soda ash, foam, Water in copious quantities
Unsuitable extinguishing media for safety reasons:
carbon dioxide, chlorinated hydrocarbons
5.2. Special hazards arising from the substance or mixture
Risk of exothermic reaction. Contact with water releases highly flammable and/or corrosive gases/vapours.
5.3. Advice for fire-fighters
Special protective equipment:
Wear self-contained breathing apparatus and chemical-protective clothing.
Further information:
Collect contaminated extinguishing water separately, do not allow to reach sewage or effluent systems. Vapours are heavier than air and may accumulate in low areas and travel a considerable distance up to the source of ignition. Sealed containers should be protected against heat as this results in pressure build-up.
Accidental release measures
Release of substance/product can cause fire or explosion. May form explosive peroxides.
6.1. Personal precautions, protective equipment and emergency procedures
Avoid contact with the skin, eyes and clothing. Avoid inhalation. Use personal protective clothing. Sources of ignition should be kept well clear.
6.2. Environmental precautions
Do not discharge into drains/surface waters/groundwater. Do not discharge into waterways or sewer systems without proper authorization. Contain contaminated water/firefighting water.
6.3. Methods and material for containment and cleaning up
For large amounts: Protect from water. Pump off product. Place into suitable container for disposal. Correctly dispose of recovered product immediately.
For residues: Protect from water. Pick up with suitable absorbent material. Place into suitable container for disposal. Correctly dispose of recovered product immediately.
6.4. Reference to other sections
Information regarding exposure controls/personal protection and disposal considerations can be found in section 8 and 13.
Handling and storage
7.1. Precautions for safe handling
Ensure thorough ventilation of stores and work areas. Protect against moisture. Refill and handle product only in closed system. Handle under dry nitrogen. Protect against heat.
Protection against fire and explosion:
Render equipment and apparatus inert (nitrogen, inert gases) and ground before putting into operation. Take precautionary measures against static discharges. Use antistatic tools. Avoid all sources of ignition: heat, sparks, open flame. Fire extinguishers should be kept handy. Sealed containers should be protected against heat as this results in pressure build-up. Vapours are heavier than air and may accumulate in low areas and travel a considerable distance up to the source of ignition.
7.2. Conditions for safe storage, including any incompatibilities
Segregate from acids and acid forming substances. Keep away from water. Segregate from alcohols.
Further information on storage conditions: Keep container tightly closed in a cool, well-ventilated place. Keep under dry nitrogen. Protect against heat. Outage of containers should be filled with dry inert gas at atmospheric pressure to avoid reaction with moisture.
Storage stability:
Keep under dry nitrogen.
Improper storage may result in pressure build up in the drums.
7.3. Specific end use(s)
For the relevant identified use(s) listed in Section 1 the advice mentioned in this section 7 is to be observed.

Exposure controls / personal protection
8.1. Control parameters
Components with occupational exposure limits
108-88-3: toluene
Skin Designation (OEL (EU))
The substance can be absorbed through the skin.
STEL value 384 mg/m3 ; 100 ppm (OEL (EU))
indicative
TWA value 192 mg/m3 ; 50 ppm (OEL (EU))
indicative
999-97-3: 1,1,1,3,3,3-Hexamethyldisilazane
8.2. Exposure controls
Personal protective equipment
Respiratory protection:
Breathing protection if gases/vapours are formed. Gas filter for gases/vapours of organic compounds (boiling point >65 °C, e. g. EN 14387 Type A)
Hand protection:
Chemical resistant protective gloves (EN 374)
Suitable materials short-term contact and/or splashes (recommended: At least protective index 2, corresponding > 30 minutes of permeation time according to EN 374)
Polyethylene-Laminate (PE laminate) - ca. 0.1 mm coating thickness
fluoroelastomer (FKM) - 0.7 mm coating thickness
Supplementary note: The specifications are based on tests, literature data and information of glove manufacturers or are derived from similar substances by analogy. Due to many conditions (e.g. temperature) it must be considered, that the practical usage of a chemical-protective glove in practice may be much shorter than the permeation time determined through testing.
Manufacturer's directions for use should be observed because of great diversity of types.
Eye protection:
Tightly fitting safety goggles (cage goggles) (e.g. EN 166) and face shield.
Body protection:
Body protection must be chosen depending on activity and possible exposure, e.g. apron, protecting boots, chemical-protection suit (according to EN 14605 in case of splashes or EN ISO 13982 in case of dust)., Protective clothing should be flame resistant.
General safety and hygiene measures
Avoid contact with the skin, eyes and clothing. Do not breathe vapour/spray. Handle in accordance with good industrial hygiene and safety practice. When using, do not eat, drink or smoke. Hands and/or face should be washed before breaks and at the end of the shift.
