Effective emergency service management requires agencies from many different services to work closely together and to have open lines of communication. Most services do, or should, have procedures and liaisons in place to ensure this, although absence of these can be severely detrimental to good working. There can sometimes be tension between services for a number of other reasons, including professional versus voluntary crew members, or simply based on area or division. To aid effective communications, different services may share common practices and protocol for certain large-scale emergencies. In the UK, commonly used shared protocols include CHALET and ETHANE while in the US, the Department of Homeland Security has called for nationwide implementation of the National Incident Management System (NIMS),[1] of which the Incident Command System (ICS) is a part.[2]

A common measurement in benchmarking the efficacy of emergency services is response time, the amount of time that it takes for emergency responders to arrive at the scene of an incident after the emergency response system was activated. Due to the nature of emergencies, fast response times are often a crucial component of the emergency service system.[6]
