●Inquiry recommendation
The Home Office, His Majesty's Inspectorate of Constabulary and Fire and Rescue Services, the College of Policing, the Fire Service College, the National Ambulance Resilience Unit and JESIP should ensure that all emergency services use common terminology to describe the zoning of hazardous areas in non-Operation Plato Major Incident situations and that all services have a common understanding of those terms. The terms should be different from those used when Operation Plato is declared.

Each entry above links to a primary source — gov.uk written statement, consultation response document, or inspection report. The Index does not characterise government intent; it tracks what has been published.
How this page is built
Source and Response are verbatim from primary documents. The Evidence trail records published activity since — written statements, consultation outcomes, inspection findings, parliamentary references. The Index does not paraphrase or characterise intent; it tracks what has been published. Where the evidence is the absence of action (a missed deadline, a slipped timetable), that absence is documented from primary sources rather than inferred.
This recommendation's data is verified periodically against primary sources. The Index is monitored for staleness weekly.
