Planning for Emergencies
...incidents, disasters & contingency
A major incident is any emergency that requires the implementation of special arrangements by one or more of the emergency services, the NHS and local authority for:

Emergencies and disasters can happen at any time, from fires to flooding, from toxic leaks to explosions and from aircraft crashes to severe weather. It can mean the loss of basic services including water, electricity, gas and telephones. It is to contain and minimise these events and their effects that the emergency services and local authorities make plans for emergencies.

Contingency or emergency planning is the term for the work that the government, the emergency services, the health services and the local authorities do in preparing plans and procedures for dealing with any emergency that might affect large numbers of people. All of the relevant organisations liaise to ensure that the emergency response will be co-ordinated, and training of staff and exercises and the plans and procedures, are carried out.
