Spillage on deck

Smother spillage with DRY inert material, collect and dispose of overboard in a safe manner.

Spillage under deck

Not applicable.

Fire on deck

Substances may burn fiercely. For small fires use dry chemicals. For larger fires smother with DRY inert material, collect and dispose of overboard in a safe manner. If possible remove receptacles likely to be involved.

Fire under deck

Not applicable.

Special equipment to be carried

Protective clothing (gloves, boots, coveralls, headgear).
Self-contained breathing apparatus.
DRY inert material (e.g. diatomaceous earth) to be maintained as dry as possible in a suitable stow.
Dry chemical.
