First-aid measures

1. Description of first aid measures
General notes
Do not leave affected person unattended. Remove victim out of the danger area. Keep affected person warm, still
and covered. Take off immediately all contaminated clothing. In all cases of doubt, or when symptoms persist, seek
medical advice. In case of unconsciousness place person in the recovery position. Never give anything by mouth. In
case of accident or if you feel unwell, seek medical advice immediately.
Following inhalation
If breathing is irregular or stopped, immediately seek medical assistance and start first aid actions. In case of respiratory
tract irritation, consult a physician. Provide fresh air.
Following skin contact
Wash with plenty of soap and water.
Following eye contact
Remove contact lenses, if present and easy to do. Continue rinsing. Irrigate copiously with clean, fresh water for at
least 10 minutes, holding the eyelids apart.

Following ingestion
Rinse mouth with water (only if the person is conscious). Do NOT induce vomiting.

2. Most important symptoms and effects, both acute and delayed
If on skin or if in eyes: Causes severe skin burns and eye damage

3. Indication of any immediate medical attention and special treatment needed

Fire-fighting measures

1. Extinguishing media
Suitable extinguishing media
Dry extinguishing powder, Carbon dioxide (CO2), alcohol resistant foam, Water spray
Unsuitable extinguishing media
Water jet

2. Special hazards arising from the substance or mixture
Develops corrosive and irritant vapours. Places which are not ventilated, e.g. unventilated below ground level areas
such as trenches, conduits and shafts, are particularly prone to the presence of vapours.
Hazardous combustion products
Carbon monoxide (CO), Carbon dioxide (CO2), Sulphur oxides (SOx), Hydrogen fluoride (HF), Silicon oxides

3. Advice for firefighters
In case of fire and/or explosion do not breathe fumes. Wear self-contained breathing apparatus. Fight fire with normal
precautions from a reasonable distance. Co-ordinate firefighting measures to the fire surroundings. Do not allow
firefighting water to enter drains or water courses. Collect contaminated firefighting water separately. Remove
undamaged containers from heat radiation. Keep containers cool with water spray. Precipitate combustion gases
with water spray if possible. Reacts violently with water.

Accidental release measures

1. Personal precautions, protective equipment and emergency procedures
Wearing of suitable protective equipment (including personal protective equipment referred to under Section 8 of the
safety data sheet) to prevent any contamination of skin, eyes and personal clothing.
For non-emergency personnel
Remove persons to safety.
For emergency responders
Wear breathing apparatus if exposed to vapours/dust/spray/gases. Eliminate all ignition sources if safe to do so. Provision
of sufficient ventilation.

2. Environmental precautions
Keep away from drains, surface and ground water. Retain contaminated washing water and dispose of it.

3. Methods and material for containment and cleaning up
Advice on how to contain a spill
Bunding, Covering of drains
Advice on how to clean up a spill
Wipe up with absorbent material (e.g. cloth, fleece). Collect spillage: sawdust, kieselgur (diatomite), sand, universal
binder.
Other information relating to spills and releases
Place in appropriate containers for disposal. Ventilate affected area.
