The APELL process is designed to build on any and all existing emergency plans to create a single co-ordinated local plan. There may be national government emergency plans in place but there is always the need for an effective structure at the local level. Industrial facilities should already have on-site emergency plans. Local authorities and rescue services should have plans to deal with the consequences of major emergencies. Local hospitals should certainly have their own "major accident plans" for dealing with large numbers of seriously injured people. The APELL process ensures that all existing plans contribute to the overall integrated, co-operative plan.
