Guidance on Safe Use

First-aid measures

Description of first aid measures

In case of inhalation: Move victim to fresh air. Seek medical treatment in case of troubles.

Following skin contact: Immediately wipe affected skin area with paper towel or cloth.

Immediately clean with water and soap followed by thorough rinsing.

In case of skin irritation, consult a physician.

After eye contact: Immediately flush eyes with plenty of flowing water for 10 to 15 minutes holding eyelids

apart. Subsequently consult an ophthalmologist.

After swallowing: Rinse mouth with water.

Never give an unconscious person anything through the mouth.

Consult physician immediately.

Most important symptoms and effects, both acute and delayed

May cause slight irritation to mucous membranes, skin and eyes.

Higher doses may have a narcotic effect.

Indication of any immediate medical attention and special treatment needed

Treat symptomatically.

Fire-fighting measures

Extinguishing media

Suitable extinguishing media::

Foam, extinguishing powder, carbon dioxide

Special hazards arising from the substance or mixture

Highly flammable liquid and vapour. With air, vapours form potentially explosive mixtures,

which are heavier than air. Vapours may proceed on the ground over great distances and

cause fire and backflashes.

In case of fire may be liberated: 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: •3YE

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, protective equipment and emergency procedures

Do not breathe vapours. Avoid contact with the substance.

In case of leakage, eliminate all ignition sources. Provide adequate ventilation.

Wear appropriate protective equipment. Keep unprotected people away.

Cordon off downwind area at risk and warn inhabitants.

Environmental precautions

Do not allow to enter into ground-water, surface water or drains. Danger of explosion!

In case of release, notify competent authorities.

Methods and material for containment and cleaning up

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 section 13). Thoroughly clean surrounding area.

In case of greater quantities: Collect mechanically (use only explosion-proof equipment

when pumping out).

Vapours form potentially explosive mixtures with air. Heavier than air, they proceed at floor

level and may backflash over great distances when ignited.

Additional information: Use explosion-proof equipment and non-sparking tools/utensils.

Take precautionary measures against static discharges.

Handling and storage

Precautions for safe handling

 

Advices on safe handling: Provide adequate ventilation, and local exhaust as needed. Do not breathe vapours.

Avoid contact with skin and eyes. Wear appropriate protective equipment.

Guarantee sufficient ventilation during and after use, in order to prevent vapour

accumulation.

Precautions against fire and explosion:

Keep away from sources of ignition - No smoking.

Take precautionary measures against static discharges.

Use only explosion-protected equipment/instruments. Do not weld.

In partially filled containers explosive mixtures may form.

 

Conditions for safe storage, including any incompatibilities

 

Requirements for storerooms and containers:

Keep container tightly closed in a cool, well-ventilated place.

Keep away from heat sources, sparks and open flames.

Protect from humidity and water.

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. Do not weld.

Keep out of the reach of children.
