1 Job Performance Requirement Hoisting Ladders by Rope

2 JPR 14-15A A A bowline or a large figure of eight on a byte knot is tied at one end at a point that will create a loop that is 9 feet in circumference or at least sufficient for the bowline knot to rest above the next set of rungs.

3 JPR 14-15B B The middle of the ladder is ascertained by counting rungs. Once the middle is established, the firefighter counts up two rungs and passes the rope through the hole that the rungs create. Strips of electrical tape or painted bands can be used to semipermanently identify these rungs. With the ladder on the ground, the butt (or base) of the ladder is gently lifted and the rope slid up to the marked rungs while the slack rope is taken up.

4 JPR 14-15C C The knot should be approximately in the center of the ladder between the beams. The ladder is then rolled over so that the rope runs under the ladder rungs and is arranged to be between the ladder and the building.

5 JPR 14-15D D The command to hoist may be given. The tip will tend to lean away from the building and prevent the ladder tip from snagging on any projections caused by windowsills, protruding brickwork, or any other structural element that might cause difficulty. Once the rope knot is at the point of raising, the ladder is pivoted on the edge of the structure and gently pulled down on the roof. Then the remaining portion of the ladder is pulled onto the roof.
