Guidance on Safe Use
Administrative data
First-aid measures
General information: Move victim out of danger zone. Position and transport victim on their side. In case of
respiratory distress, bring into semi-upright, seated position. Remove contaminated
clothing immediately and dispose of safely. Put victim at rest, cover with a blanket and
keep warm. Do not leave affected persons alone. In case of accident or unwellness,
seek medical advice immediately (show directions for use or safety data sheet if possible).
After inhalation: Provide fresh air. In case of breathing difficulties administer oxygen. No mouth-to-mouth
or mouth-to-nose resuscitation. Use Ambu bag or ventilator. Immediately get medical
attention.
In case of skin contact: Remove contaminated clothing immediately and dispose of safely.
After contact with skin, wash immediately with plenty of water. Subsequently wash off
with: ammonia (3 5).
After eye contact: Immediately flush eyes with plenty of flowing water for 10 to 15 minutes holding eyelids apart.
After contact with skin, wash immediately with plenty of water. Subsequently wash off
with: soda solution, diluted.
Subsequently consult an ophthalmologist.
After swallowing: Rinse mouth immediately and drink plenty of water. Give activated carbon (20 - 40 g in a
suspension of 10%). Danger of aspiration!
Do not induce vomiting.
Fire-fighting measures
Extinguishing media
Suitable extinguishing media:
Foam, extinguishing powder.
Extinguishing media which must not be used for safety reasons:
Water.
Special hazards arising from the substance or mixture
Combustible
May form dangerous gases and vapours in case of fire.
In case of fire may be liberated: Sulphur oxides, carbon monoxide and carbon dioxide.
Advice for firefighters
Special protective equipment for firefighters:
Wear self-contained breathing apparatus.
Wear suitable protective clothing.
Use acid-proof equipment only.
Additional information: Cool endangered containers with water jetspray. Use water spray jet to knock down vapours.
Do not allow fire water to penetrate into surface or ground water.
If necessary notify appropriate authorities.
Accidental release measures
Personal precautions, protective equipment and emergency procedures
Wear suitable protective clothing.
Environmental precautions
Cover drains. Do not allow to penetrate into soil, waterbodies or drains.
Methods and material for containment and cleaning up
Plug leak if safely possible. 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 (see chapter 13).
Handling and storage
Precautions for safe handling
Advices on safe handling Wear suitable protective clothing.
When using do not eat, drink, smoke, sniff.
The danger areas must be delimited and identified using relevant warning and safety signs.
Work place should be equipped with a shower and an eye rinsing apparatus.
Working places should be designed to allow cleaning at any time.
Precautions against fire and explosion:
The floor should be leak tight, jointless and not absorbent. Do not use air pressure to deliver.
Usual measures for fire prevention.
Inspect electric installations more frequently for corrosion damage.
Welding operations are permitted only under supervision.
Conditions for safe storage, including any incompatibilities
Requirements for storerooms and containers:
Keep container tightly closed. Keep only in the original container.
storage temperature: 10 °C up to 30 °C.
Average shelf life of 2 years.
Use shatter-proof packaging.
Protect from moisture contamination. Protect from sunlight.
Only trained personnel may be allowed to enter storage area.
Hints on joint storage Keep away from food, drink and animal feeding stuffs.
Storage class: 6.1 A = Combustible toxic substances
