Emergency procedures

Action

Avoid all sources of ignition (e.g. naked lights, unprotected light bulbs, electric handtools).
Turn ship off-wind.

Spillage on deck

Wash spillage overboard with copious quantities of water.

Spillage under deck

Provide adequate ventilation. Collect spillage, where practicable, using absorbent material, for safe disposal.

Fire on deck

Use water spray or dry chemical. Do NOT use water jet or foam.
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.

Remarks by UN no.

HYDRAZINE, ANHYDROUS (UN No. 2029)
Possible self-ignition at ambient temperatures.
