Fire-fighting measures

- Extinguishing media:


Carbon dioxide (CO2)

- Hazards during fire-fighting:

In the event of fire it can be released

Sulfur oxides (SOx)

carbon monoxide (CO)

- Protective equipment for fire-fighting:

In the event of fire, wear self-contained breathing apparatus.

Use personal protective equipment.

- Fire-fighting / further advice:

Do not allow any contaminated quenching agent to get into the sewerage system.

Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations.

Use water spray to cool unopened containers.

Accidental release measures

- Personal precautions:

Limit duration and extent of exposure.

Ensure adequate ventilation.

Avoid contact with the skin and the eyes.

Keep people away from and upwind of spill/leak.

- Environmental precautions:

Must not get into the soil, sewerage systems and surface water. In the event of contamination, notify the responsible authorities.

- Methods for cleaning or taking up:

Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal binder, sawdust).

Handling and storage

- Advice on safe handling:

The product must be handled in closed plants.

Before a closed system is opened, purging and washing of the system have to be applied.

Only trained and authorised personnel is allowed to handle the substance.

Limit duration and extent of exposure.

Handle only in a well-ventilated room. Use exhauster devices.

Avoid contact with skin and eyes.

Provide emergency eye-rinse and shower for entire body.

Document substance-handling procedures. Supervise handling by site operator.

- Fire and explosion protection:

Keep away from heat and sources of ignition.

Avoid overheating.

- Storage requirements:

Keep container tightly closed in a dry and well-ventilated place.

Store at room temperature in the original container.

Use PTFE seals.
