Job Performance Requirement 14-7 Three-Person Raise
A Firefighters will find it necessary to use additional firefighters to raise the larger ladders, due to ladder weight and size. With a three-person ladder raise, a rung raise should be used. The ladder may be carried using any one of the carries, but, once the ladder butt is placed on the ground, the ladder should be pivoted to the rung raise position with the fly section out prior to the raise. (The ladder can be pivoted before raising the fly section, if necessary.)
BThe heeler remains at the butt end to heel the ladder. The firefighter in the mid position moves to the tip end and takes one of the beams from the raiser. Both of these firefighters are now raisers. JPR 14-7B
CThe raisers lift the ladder and each places a beam upon their shoulder. The heeler crouches down and grabs a rung with both hands and gives the command and the raisers lift the ladder up and position under their respective beam. JPR 14-7C
DWith their arms extended straight, each raiser proceeds toward the building, using the beam to lift the ladder. (If the fly section remains in, the ladder can be pivoted at this point to move it to the outside.) The raisers now accept the weight and stability responsibility of the ladder. They each move to a position on the sides of the ladder and use their hands and feet to steady the ladder. JPR 14-7D
EIt is important for these firefighters to keep their hands away from the moving fly section and keep them on the outside of the beam. The heeler grasps the halyard and extends the ladder to the proper position. All three firefighters watch the operation and watch to ensure the ladder is at the proper position and locked. JPR 14-7E
FThe heeler then grasps the ladder with one hand on each beam. The raising firefighters then move back to the outside of the ladder. Each places a foot on the bottom rung, while the inside firefighter uses both feet to steady the ladder on the ground. All three firefighters lower the ladder into the objective until the tip is resting on the objective. JPR 14-7F
