-       Keep containers and surroundings cool with water spray.

-       Suppress (knock down) gases/vapours/mists with a water spray jet.

-       Flood the product with water.

-       Avoid propagating the fire when directing the extinguishing agent as a jet onto the surface of the burning liquid.

-       Evacuate personnel to safe areas.

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Advice for non-emergency personnel

-       Prevent further leakage or spillage if safe to do so.

Advice for emergency responders

-       Keep away from open flames, hot surfaces and sources of ignition.

-       Wear self-contained breathing apparatus in confined spaces, in cases where the oxygen level is depleted, or in case of significant emissions.

-       Ventilate the area.

Environmental precautions

-       Should not be released into the environment.

Methods and materials for containment and cleaning up

-       Dam up.
