Fire-fighting measures

Recommended extinguishing agent: Extinguish with dry chemical or foam.

Product arising from burning: Carbon dioxide, Carbon monoxide, oxides of Phosphorus.

Product determined by test: N

Protective equipment: A self contained breathing apparatus and suitable protective
clothing should be worn in fire conditions.

Accidental release measures

Emergency measures in case of spillage: Avoid release to the environment. Spillages of Alpha Ligand
will be easily detected because of the pungent
characteristic smell. Collect using a high efficiency vacuum
cleaner. Transfer to a container for disposal or recovery.
Spillages or uncontrolled discharges into watercourses must
be alerted to the appropriate regulatory body.

Material is suitable for recovery. Spent catalyst or waste
material to be returned to manufacturer for

Handling and storage

Handling: Alpha Ligand is an air and moisture sensitive material. It
will arrive on-site in specially designed, air-tight
packaging, which is designed so that it can be transferred
to a process vessel with no exposure to air. It should not
be transferred to another container prior to use.

Storage: Keep only in the original container. Keep container tightly
closed and dry. Store under Nitrogen. Material will be
present on manufacturing sites in relatively small
quantities i.e. less than 500 Kg at any given time. Storage
temperature 0-40 deg C.

Packaging of the substance and or preparation: 60L Stainless Steel pressure vessel (UN Tariff No. BOE-6000)
