MARPOL pollution category

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

Action

Turn ship off-wind.

Spillage on deck

Wash spillage overboard with copious quantities of water from as far away as practicable. Contaminated clothing must be removed and washed carefully with copious quantities of water.

Spillage under deck

Collect spillage, where practicable, using inert absorbent materials, for safe disposal. Do not use sawdust or other combustible materials as absorbents. Contaminated clothing must be removed and washed carefully with copious quantities of water.

Fire on deck

Use copious quantities of water from as far away as practicable.

Fire under deck

Ship's fixed fire-fighting installation may not be effective. 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).

Remarks by UN no.

TETRANITROMETHANE (UN No. 1510).
May explode in a fire situation.

HYDROGEN PEROXIDE, AQUEOUS SOLUTIONS (UN No. 2984), with not less
than 8% but less than 20% hydrogen peroxide.
Self-contained breathing apparatus not necessary - use goggles for eye protection.
