Powers and duties of local authorities - Offensive trades

56: Local authority to notify medical officer of health of registered chemical works

You could also call this:

"Tell the medical officer about chemical works in your local area"

If you are in charge of a local area, you have to tell the medical officer of health about any chemical works that are registered in your area. The medical officer of health needs to know about these chemical works. You can find more information about this in the Health Act 1956, but this specific part has been repealed, which means it is no longer in effect, and was stopped on 1 April 1974 by the Clean Air Act 1972.
