Radioactivity (Fire Service Guidance) Mr. Redmond asked the Secretary of State for the Home Department, pursuant to the reply of 15 January, Official Report, column 253, when the last review of the June 1984 "Guidance to Fire Service at Incidents Involving Radioactivity" was conducted; if any other specific guidance is issued to chief fire officers in the handling of incidents involving radioactivity arising from the transportation of radioactive weapons' materials; and if any guidance is issued to chief fire officers regarding the procedure for advance notification of the timings and routes of radioactive weapons' materials convoys to specific chief fire officers whose administrative areas are to be passed through. Mr. Douglas Hogg The guidance on the role of the fire service at incidents involving radioactivity is about to be reviewed. As I indicated in my answer of 15 January, it is the policy of this Government, as it has been of their predecessors, not to comment in detail on the transportation of radioactive weapons materials. There is continuing liaison between representatives of chief fire officers and Ministry of Defence staff about the role of the fire service in the handling of incidents involving radioactive materials.
