Fire-fighting measures

Suitable extinguishing media: Water, water mist, Alcohol-resistant foam.

Extinguishing media which must not be used for safety reasons: Full water jet

Special exposure hazards arriving from substance or preparation itself, combustion products, resulting gases:

Fire may produce: Hydrogen cyanide (HCN), Ammonia, Formaldehyde vapours, Nitrogen oxides (NOx), Carbon monoxide and carbon dioxide.

Special protective equipment for fire-fighters: Wear self-contained breathing apparatus and protective suit.

Additional information:

Cool containers at risk with water spray jet. Do not release chemically contaminated water into drains, soil or surface waters. Sufficient measures must be taken to retain water used for extinguishing.

Accidental release measures

Personal precautions:

Avoid dust formation.

Avoid contact with skin, eyes and clothing. Use personal protective clothing. Ensure adequate ventilation. Keep away from sources of ignition - No smoking.

Environmental precautions: Do not discharge into the drains/surface waters/groundwater.

Methods for cleaning up/taking up: Pick up mechanically, avoiding dust, and provide disposal in suitable recipients. Clean contaminated surface thoroughly. Flush away residues with water.

Handling and storage

Handling:

Advice on safe handling:

Avoid the formation and deposition of dust. Care for suitable extraction / ventilation at processing machines. Keep container tightly closed. Protect from moisture. Avoid contact with skin, eyes and clothing.
