First-aid measures

Emergency measure - Eyes: Wash with water
Emergency measure - Skin: Wash with soap and water
Emergency measure - Ingestion: Seek medical attention

Fire-fighting measures

Recommended extinguishing agent: Combustion products may contain carbon, nitrogen and
sulphur oxides together with some hydrogen chloride gas,
nickel compounds and some soot. A self-contained breathing
apparatus should be used. Suitable extinguishing agents are
water, dry powder, foam and carbon dioxide.

Accidental release measures

Emergency measures in case of spillage: Solid: Collect and dispose of at a landfill site or by
incineration. Solutions: Dilute with a large volume of
water and discharge to a water treatment plant in
accordance with local/national regulations. In some cases
liquid spills may be absorbed using suitable material.
Waste should be disposed as for solids.

Handling and storage

Handling: The usual precautions for handling chemicals should be
observed.

Storage: No special precautions. The substance is normally stored in
closed containers in adequate rooms.

Disposal considerations

Industry - Possibility of recovery/recycling: In normal use 40-50% of the substance is consumed. It is
not possible to recover the remaining 50-60%.

Industry - Possibility of neutralisation: Not applicable, the substance has no known hazardous
effects.

Industry - Possibility of destruction: controlled discharge: Disposal at a landfill site is possible.

Industry - Possibility of destruction - incineration: A suitable facility which can remove the NOx, SOx and HCl
gases should be used.

Industry - Possibility of destruction - water purification: Industrial waste water will contain 50-60% of the substance
after dyeing. Treatment by the user will be in an internal
treatment plant. Three main methods may be used: (1)
Ultrafiltration using a Deval Cr 20 membrane. (2)
Flocculation using a cationic copolymer (0.5g/l). (3)
Oxidation with ozone at pH11. The above methods should
remove up to 99% of the waste dyestuff. The nickel
concentration will be reduced from 6-7 ppm before treatment
to less than 0.1 ppm after treatment. The residues formed
during treatment may be disposed of by landfill or
incineration.

Public at large - Possibility of recovery/recycling: The substance itself will not enter the public domain.
