Otherwise, spray unopened containers with water to keep cool. Whenever
possible , contain fire-fighting water by bunding area with sand or earth.
6. ACCIDENTAL RELEASE MEASURES

becomes contaminated remove it immediately. When dealing with the spillage do
not eat, drink or smoke and wear personal protective clothing as detailed in
Section 8.
Environmental Precautions Keep people and animals away. Prevent entry into drains, sewers and
watercourses. In the UK if spillage enters drains leading to sewage works inform
local water company plc immediately. If spillage enters rivers or watercourses,
inform the Environment Agency (emergency telephone number 0800 807060).
Overseas, inform the appropriate authority immediately.
Spillages Sweep or preferably vacuum up spillage using equipment fitted with high
efficiency final filter. Avoid creating a dust. Transfer collected material to heavy
duty plastic drums and keep safe for disposal.
Note Check also for any local site procedures in force.
