MOLTEN CORROSIVE SUBSTANCES.

Emergency procedures

Spillage on deck

Disconnect source of heat. Allow to solidify, possibly to plug leak. After solid material has cooled down, collect for safe disposal.

Spillage under deck

Adopt action for "On deck".

Fire on deck

Use water spray.

Fire under deck

Batten down; use 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.
Inert material (e.g. sand).

Remarks by UN no.

• HEXAMETHYLENEDIAMINE, SOLID (UN No. 2280)
Contain molten product, using inert material.

• PHOSPHORUS OXYBROMIDE, MOLTEN (UN No. 2576)
Non-combustible. Use of water on substances may cause violent reaction.
