§ Mr. Wigley
To ask the Secretary of State for the Home Department what regulations govern(a) the holding by fire brigades of lists of premises where significant quantities of pesticides and related chemicals such as sheep dips are stored and (b) procedures for not using large volumes of water in the event of fires at such premises; and if he will make a statement. 
§ Mr. Sackville
Fire authorities have arrangements, under section 1(1)(d) of the Fire Services Act 1947, for obtaining, by inspection or otherwise, information required for firefighting purposes with respect to the character of premises in their areas. Where premises contain significant quantities of any dangerous substance, the occupier has to inform the local authority under the Notification of Dangerous Substances (Notification and Marking of Sites) Regulations 1990.
The Home Office has issued detailed guidance to the fire service on procedures for using water in the event of fires at such premises.
