NFPA 1710 exists because studies into firefighting prove that there must be a certain number of people per rig arriving on scene within a specified time frame to offer citizens the minimum level of protection. Note the word "minimum" because some believe the standard offers the maximum.
NFPA 1710 Requirements:
Fire Fighters will respond with a minimum of 4 personnel on each apparatus and more depending on the hazards normally encountered (can be five or six).
Fire Fighters will arrive at the emergency scene within 4 minutes of the dispatch center receiving the call.
The correct number of fully staffed and strategically located fire stations must exist to accomplish the standard.
NFPA Code 1710-Standard for Organization and Deployment of Fire Suppression Operations, Emergency Medical Operations, and Special Operations to the Public by Career Fire Departments- involves staffing of career fire departments. In this code, the NFPA has used scientific evidence, past history and first hand experience to establish the minimum number of personnel required to safely and effectively operate on a fire scene. NFPA 1710 guidelines say that a first arriving company must consist of 4 fire fighters and arrive within 4 minutes of the initial 911 call. For an initial full alarm assignment (any structure fire) minimum personnel on scene should consist of 15-17 fire fighters arriving on scene within 8 minutes of the initial 911 call.
