Guidance on Safe Use
Administrative data
First-aid measures
- General advice: Ensure that medical personnel are aware of the material(s) involved, and take precautions to protect themselves.
- Following inhalation: Move victim to fresh air. Seek medical treatment in case of troubles.
- Following skin contact: Wash with generous amount of water and soap. Take off contaminated clothing and wash it before reuse. If skin irritation occurs: Get medical advice/attention.
- Following eye contact: Immediately flush eyes with plenty of flowing water for 10 to 15 minutes holding eyelids apart. Remove contact lenses, if present and easy to do. Continue rinsing. In case of troubles or persistent symptoms, consult an opthalmologist.
- Following swallowing: Rinse mouth with water. Never give anything by mouth to an unconscious person. Immediately get medical attention.
- Most important symptoms and effects: Inhaling can lead to irritations of the respiratory tract and mucous membrane.
Higher doses may lead to a narcotic effect.
- Indication of any immediate medical attetion and special treatment needed: Treat symptomatically.
Fire-fighting measures
Extinguishing media:
- Suitable extinguishing media: Water mist, foam, extinguishing powder, carbon dioxide.
- Extinguishing media which must not be used for safety reasons: Full water jet.
Special hazards arising from the substance or mixture:
Flammable liquid and vapour. With air, vapours form potentially explosive mixtures, which are heavier than air. In case of fire may be liberated: traces of incompletely burned carbon compounds, formaldehyde, silicon dioxide, carbon monoxide and carbon dioxide.
Advice for firefighters:
- Special protective equipment for firefighters: Wear self-contained positive pressure breathing apparatus and full firefighting protective clothing.
- Additional information: Hazchem-Code: •3Y
Heating will lead to pressure increase: Danger of bursting and explosion. Use fine water spray to cool endangered containers.
Move undamaged containers from immediate hazard area if it can be done safely. In case of major fire and large quantities: Evacuate area. Fight fire remotely due to the risk of explosion.
Do not allow fire water to penetrate into surface or ground water. Fire residuals and contaminated extinguishing water must be disposed of in accordance with the regulations of the local authorities.
Accidental release measures
- Personal precautions:
Avoid breathing vapours. Avoid contact with the substance.
Eliminate all ignition sources if safe to do so. If possible, eliminate leakage. Provide adequate ventilation.
Wear appropriate protective equipment. Keep unprotected people away.
- Protective equipment and emergency procedures:
Do not allow to penetrate into soil, waterbodies or drains. Danger of explosion! In case of release, notify competent authorities.
- Methods and material for containment and cleaning up:
Wipe up with absorbent material (eg. cloth, fleece). Cleaning surfaces by wiping, brushing.
In case of spills of large quantities: Stop leak if safe to do so. Dam spills. Cover spilled material with plastic sheet. Isolate leaked material using non-flammable absorption agent (e.g. sand, earth, vermiculit, diatomaceous earth) and collect it for disposal in appropriate
containers in accordance with the local regulations.
Never return spills in original containers for re-use.
Additional information: Use explosion-proof equipment and non-sparking tools/utensils. Special danger of slipping by leaking/spilling product.
- Reference to other sections: Refer additionally to section "Exposure controls/personal protection" and "Disposal considerations".
Handling and storage
Precautions for safe handling:
- Advices on safe handling: Provide adequate ventilation, and local exhaust as needed. Avoid breathing vapours. Do not get in eyes, on skin, or on clothing. Wear appropriate protective equipment. Do not eat, drink or smoke when using this product. Wash hands thoroughly after handling. Contaminated work clothing should not be allowed out of the workplace. When handling large quantities, supply emergency spray.
- Precautions against fire and explosion: Use only closed, grounded equipment with this product. Usual measures for fire prevention. Do not weld. Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking.
Take precautionary measures against static discharge. Use explosion-proof equipment and non-sparking tools/utensils.
Conditions for safe storage, including any incompatibilities:
- Requirements for storerooms and containers: Keep only in the original container in a cool, well-ventilated place. Keep container tightly closed and dry. Keep away from heat sources, sparks and open flames. Protect from direct sunlight. Store containers in upright position. Do not drop, drag or bang the container. Handle empty containers with care. Incineration may cause explosion. Do not re-use the empty container.
- Hints on joint storage: Do not store together with combustible or self-igniting materials or any highly flammable solids. Keep away from food, drink and animal feedingstuffs.
