Category	Description
X	Noxious Liquid Substances which, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a major hazard to either marine resources or human health and, therefore, justify the prohibition of the discharge into the marine environment.

CORROSIVE SUBSTANCES, NOT COVERED BY OTHER SCHEDULES

Emergency procedures

Action

Use of water on substance may cause violent reaction.
Avoid all sources of ignition (e.g. naked lights, unprotected light bulbs, electric handtools).
Turn ship off-wind.

Spillage on deck

Wash overboard with copious quantities of water from as far away as practicable.

Spillage under deck

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

Fire on deck

Use water spray from as far away as practicable. Wash deck in vicinity with copious quantities of water. If possible, remove receptacles likely to be involved or keep them cool with copious quantities of water.

Fire under deck

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

Special equipment to be carried

Protective clothing (gloves, boots, coveralls, headgear).
Self-contained breathing apparatus.
Spray nozzles.
