Category Description
Y Noxious Liquid Substances which, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a hazard to either marine resources or human health or cause harm to amenities or other legitimate uses of the sea and therefore justify a limitation on the quality and quantity of the discharge into the marine environment.

Emergency procedures

Spillage on deck

Use of water on substance may cause violent reaction. Wash overboard with copious quantities of water from as far away as practicable.

Spillage under deck

Collect spillage, where practicable, using inert absorbent material for liquids, for safe disposal.

Fire on deck

If possible remove receptacles likely to be involved or keep them cool with water.

Fire under deck

Adopt action as for "On deck".

Special equipment to be carried

Protective clothing (gloves, boots, coveralls, headgear).
Self-contained breathing apparatus.
Inert absorbent material (e.g. diatomaceous earth)
Spray nozzles.
