Nigeria - Final Regulatory Action
Polychlorinated Biphenyls (PCBs) CAS number:
Date circular:

Chemical name: 1,1'-Biphenyl, chloro derivs.

Final regulatory action has been taken for the category: Industrial

Final regulatory action: The chemical is Severely Restricted

Use or uses prohibited by the final regulatory action:

All new uses are prohibited with the exception of those currently in use as transformer oil.

Use or uses that remain allowed:

Severely restricted as dielectric fluid in transformers.

The final regulatory action was based on a risk or hazard evaluation: Yes

Summary of the final regulatory action:

Included in the List of Hazardous (Dangerous) Chemical Products (FAC 000-000-9903)/Acutely Hazardous (Dangerous) Chemical Products under SCHEDULE 13 of the S.I.15 Regulations (Management of Solid and Hazardous Wastes) of 1991 and in the Public Notification of 17 June 1998 in the Daily Times and Guardian Newspapers.

The reasons for the final regulatory action were relevant to: Human health and environment

Summary of known hazards and risks to human health:

Information on hazards to human health was as specified in the relevant Decision Guidance Document

Expected effect of the final regulatory action in relation to human health:

The ban on importation of this product under the RC may impact on the national authority responsible for power generation in the country and other industrial facilities dependent on the product as dielectic fluid. Some of this equipment is gradually being phased out, but the economic implications have slowed down this process.
Severely restricting or banning the chemical will therefore reduce human exposure and risk to human health.

Summary of known hazards and risks to the environment:

Information on hazards to the environment is as specified in the DGD.

Expected effect of the final regulatory action in relation to the environment:

Reduction of risk to wildlife, aquatic animals and the ecosystem in general.
