Emergency procedures

Spillage on deck

Collect spillage, where practicable, for safe disposal. Wash remainder overboard with copious quantities of water.

Spillage under deck

Collect spillage, where practicable, for safe disposal.

Fire on deck

Use copious quantities of water or other medium to fight fire and cool down receptacles.

Fire under deck

Batten down; use ship's fixed fire-fighting installation. Otherwise adopt action as for "On deck".

Special equipment to be carried

Full protective clothing (gloves, boots, coveralls, headgear, goggles).
Self-contained breathing apparatus.

Remarks by UN no.

Wear self-contained breathing apparatus when dealing with spillage.

• DINITRO-ortho-CRESOL (UN No. 1598)
In fire, explosion hazard.

• ASBESTOS, BLUE (UN No. 2212)
Wear self-contained breathing apparatus when dealing with spillage.

In fire situation, use copious quantities of water. Ship's fixed fire-fighting installation may not be effective.

• CASTOR BEANS (UN No. 2969)
Wear self-contained breathing apparatus when dealing with spillage.
