asked the Paymaster General, further to the answer of 16 December 1986, Official Report, column 528, about dangerous substances, whether all 118 sites notified to the Health and Safety Executive were included in the list of sites published by the Health and Safety Executive in its news bulletin 1986–972 on 28 March 1986.

None of these sites were included in the list published on 28 March 1986. The extent to which such sites are capable of presenting a major accident hazard is still being investigated by the Health and Safety Executive.
