- Ventilate the area.

Dam up.

- Prevent product from entering sewage system.

- Contain the spilled material by bunding


- Contain spillage, soak up with non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite) and transfer to a container for disposal according to local / national regulations (see section 13).

- Keep in suitable, closed containers for disposal.

- Keep in properly labelled containers.

- Use approved industrial vacuum cleaner for removal.


- Wash off with plenty of water.
