First-aid measures

In case of inhalation : remove the person from the polluted area. Keep the injured person in security lateral position in a warm place. Give oxygen and /or artificial respiration if necessary. Get medical attention immediately.

In case of skin contact : remove immediately all contaminated clothing. Take a shower and rinse the whole body with plenty of water. Alert a doctor.

In case of eyes contact : wash eyes immediately with running water for at least 15 minutes while eyelids open. Ask immediately an ophthalmologist's advice.

In case of ingestion : get medical attention immediately. Do not induce vomiting.

Fire-fighting measures

Suitable extinguishing media : carbon dioxide, chemical powder, sprayed water, foam.

Specific fire hazards : explosive hazards of vapour in air - limits of explosivity : 2,5% -98% (v/v). Dangerous decomposition products : carbon oxides, nitrogen oxides.

Protective equipment for fire-fighters : wear self-contained breathing apparatus and chemical protective chothing.

Extinguishing waters should be collected to avoid contamination of the environment.

Accidental release measures

Personal precautions : evacuate people from the hazardous area. Remove any ignition source. Wear self-contained breathing apparatus and chemical protective clothing. Use anti-explosion equipment. Ventilate enclosed volume.
Vapours form explosive air-vapour mixture.

Environmental protection : avoid release to the environment. Do not empty into drains.

Methods for cleaning up : in case of accidental spillage with non inflammation, flood immediately with plenty of water. Destroy the product by incineration in an authorized facility in accordance with regulation.

Handling and storage

Handling : avoid contact with skin and eyes. Exhaustive ventilation at vapours emission source. Keep away from sources of ignition. Avoid formation and accumulation of static electric charges during transfer operations.

Storage : avoid any igntion source. Keep away from heat, sparks and flame. Store in a cool and well-ventilated area. Keep under inert gas. Store away from incompatible substances such as strong oxidizers, strong acids, metal oxides...
