Based on the National Fire Protection Association 1710 Standard, fire turnout time measures the interval between the time of dispatch (notification of the emergency alarm) until the first company is en-route to the emergency incident (wheels rolling). A company means a department apparatus (e.g. attack trucks, quints, engines, etc.) and crew used to respond to emergencies in a first responder's role. This measure focuses on how quickly personnel can react to emergency medical services (EMS) incidents and is one of three time components defined in NFPA Standard 1710 4.1.2.1 (2) relating to emergency response system performance. (The others being call receipt and processing time and response time.) The overall goal is to minimize systemwide response times to increase the likelihood for positive patient outcomes and minimize property damage. Increased turnout times may signal a number of things, including inefficient station configurations, gaps in operating procedures and training and limited staffing availability (e.g. due to personnel responding to other emergency events).

The data is retrieve from the Spotfire Dashboard. The specific file is "Reaction time for EMS incidents". The calculation is the based on the "Responding Time" stamp minus the "Dispatch Time" stamp. Only EMS call types are factored in (calls types beginning with the number 3) and only incidents that include a "responding" timestamp. An additional filter is that only first responder companies are factored in (Engine, Quints, Trucks, Attacks).

Actual = (# with reactiion time less than 60 seconds / total EMS calls) * 100
