HC Deb 18 March 1982 vol 20 c184W
Mr. Sheerman

asked the Secretary of State for Northern Ireland whether any incidents involving polychlorinated byphenyl occurred in Northern Ireland as a result of electrical equipment being damaged by terrorist action; and if he will publish the details of any such incidents.

Mr. Adam Butler

On 5 August 1981 a bomb explosion at Adelaide Street, Belfast damaged an electricity transformer containing polychlorinated biphenyl. Liquid which leaked from the damaged transformer was collected and disposed of, and steps were taken to deal with contamination to drains. The premises affected were checked to ensure that there was no health risk to the occupants.
