Used to lower a FF or another person from a roof or upper floor to a position of safety OR to lower a FF from a roof or upper floor to enable the FF to remove another person from an untenable position to one of safety.
Member #1, the lowering member, attaches the snap hook of the LSR to the “O Ring” of the Life Belt.
Member #1 attached the snap hook of the LSR to the bottom part of the hook of their harness when using the Personal Harness.
Member #2 attaches the snap hook of the LSR to the harness handle of their Personal Harness when using the Personal Harness.
When both members are using their Personal Harness, the bowline on a night MUST be untied.
Approximately 5” of the anti-chaffing device should be draped over the parapet or roof edge.
Substantial objects include bulkheads, an aerial ladder, chimney, cutting a hole in the roof and tying the rope around an exposed beam.
Plumbing vent pipes, sheet metal housings for roof vents, TV masts, newel posts and banisters should not be used as substantial objects.
If a 3rd member is available, that member should be at the roof’s edge for control and to relay commands.
The lowering point must be MIDWAY a between the roof’s edge and the substantial object.
When performing any lowering operation, the LSR must be as perpendicular as possible to the roof’s edge at the point where the member descends.
The lowering member must give the command “STOP” to halt the lowering operation while out of reach of the victim.
The member should then be lowered until they are shoulder to shoulder with the victim.
The rescuer should pull themselves to the victim by using the window frame. NEVER use the victim for help.
When a guide member is at roof level and visibility is good, hand signals can be used as follows: LOWER (point downward with fingers) STOP (clench fists).
