Effective emergency response depends on communication—the ability to maintain situational awareness through the constant flow of information.
During and after Hurricane Katrina, communications systems failed, severely hampering information flow and response operations. In New Orleans, most of the city was flooded. The combined effects of wind, rain, storm surge, breached levees, and flooding knocked out virtually the entire infrastructure—electrical power, roads, water supply and sewage, and communications systems.
[Thomas Stone, Fire Chief, St. Bernard Parish: “We lost our communications system, and when you are not able to communicate, you can’t coordinate your response. You never think that you will lose your entire infrastructure.”]
Communications problems are not limited to systems being destroyed or not functioning. Similar problems arise when agencies cannot exchange needed information because of incompatible systems. NIMS identifies several important features of public safety communications and information systems.
Communications systems need to be . . .
Interoperable—able to communicate within and across agencies and jurisdictions.
Reliable—able to function in the context of any kind of emergency.
Scalable—suitable for use on a small or large scale as the needs of the incident dictate.
Portable—built on standardized radio technologies, protocols, and frequencies.
Resilient—able to perform despite damaged or lost infrastructure.
Redundant—able to use alternate communications methods when primary systems go out.
Secure—able to protect sensitive or classified information from those without a need to know.
Regardless of the communications hardware being used, standardized procedures, protocols, and formats are necessary to gather, collate, synthesize, and disseminate incident information. And in a crisis, life-and-death decisions depend on the information we receive.
