For the 2018 edition, the reference to NFPA 72 in Section 11.10.2 was replaced with a reference to NFPA 1221, Standard for the Installation, Maintenance and Use of Emergency Services Communications Systems. The proper application and mediation of these elements can enable to share vital information with different responders in a timely manner. They are most frequently used in trunklines that carry long distance calls. A collection of repeaters connected together provide mobile portable radio users coverage over an extremely wide area, thus extending the range of communications. Although fire departments are being asked to be a part of these multi-agency systems, they are often not part of the process of defining the specifications. In order to explain the importance of communication during all phases of emergency management, one must first know the four phases of emergency management.
