Suitable extinguishing media and instructions
As appropriate to surrounding fire.
Firefighting Instructions: Firefighters should wear self-contained breathing apparatus and
protective clothing to prevent contact with skin and eyes.
6 Accidental release measures
Wear self-contained breathing apparatus, rubber boots and heavy rubber gloves. Sweep up,
place in a bog and hold for waste disposal. Avoid raising dust. Ventilate area and wash spill site
after material pickup is complete.
