Through the late 1960s and early 1970s the London Fire Brigade introduced RIT procedures using EATL and EASE equipment (Emergency Air Transfer Lines & Emergency Air Supply Equipment). This consisted of designated firefighter search & rescue teams (termed Emergency Crews) stationed at BA control entry points, equipped with emergency SCBA specifically designed to be worn by unconscious, injured or trapped firefighters.
More fire fighters die in residential occupancies than in any other type of structure fire and are typically the most common type of occupancy that fire fighters encounter. Both the NFPA and OSHA have requirements for some type of RIT at structure fires. These standards requiring that a minimum of two fire fighters be standing by outside in full protective equipment, while other crew meembers are working in a hazardous atmosphere, are the result of a series of incidents where fire fighters became lost, trapped, or disoriented while fighting a structure fire without a RIT present.
The Rapid Intervention Team is a unit made up of emergency responders trained in emergency scene rescue techniques. The team's objective is to rescue emergency responders who become trapped, injured or missing during response activities.
