NFPA 414 describes HRET as an elevated boom or booms designed to deliver large amounts of agent. FAA research has shown fighting fire with an HRET in a down-in-front low attack position as compared to a roof turret on a P-19 apparatus extinguished a fuel fire 53% faster and used 400% less agent. Agent delivery from a turret with discharge rates of 500 – 1000 gpm was more precise, aimed at the base of the fire, and was not as susceptible to wind and plumes of smoke carrying away agent. Position the apparatus at the nose or the tail of the aircraft, depending on wind direction, and agent can be delivered under the fuselage, at an engine or APU, a wheel assembly or simply utilizing the 60 degree rotation left and right to extinguish a pool of fuel without having to reposition the apparatus.
HRET may also include a piercing nozzle option of various lengths, depending on needs. They are designed to make quick and aggressive attacks on aircraft interior fires on both passenger and cargo aircraft. Utilizing a piercing nozzle to deliver agent at 250 gpm reduced interior temperatures from 1500 degrees F to 250 degrees F.
Make training fun. Training should be documented. If it’s not documented, it didn’t happen. Training should build the operators confidence toward certification/recertification. As per FAA A/C 5210-23, operators are required to recertify annually every 12 consecutive months. Training should include:
High Reach Extendable Turret (HRET) is a very versatile tool if used correctly. Training needs to go beyond just being able to operate the controls. DFW FTRC offers a 3-day comprehensive course beginning with HRET basic operations and focusing on tactics and strategies. We have several mockups to train on, ranging from PAST device, 727 Cargo, 727 SAFT, and A-380. Reserve your spot today!
