2-14. AERIAL LADDER SET-UP
If overload horn sounds, immediate action should be taken to
correct the overload condition. Failure may result in damage to
equipment or injury to personnel.
General Safety Guidelines. The aerial ladder is designed to support a maximum of 400 pounds live
load at the ladder tip. If loading capacity exceeds the safety limit (a red line condition) a warning horn
will sound. The horn will continue to sound until the overload situation is corrected.
(1) Use one or more of the following procedures to correct the overload condition:
Remove or reposition ladder occupant(s).
Retract ladder sections.
Slowly increase ladder elevation.
Do not rest the ladder on any type of support (window ledge,
overhang, or other structure). Pressure on the laddertip may
result in equipment damage or injury personnel.
(2) The ladder is designed as a cantilevered structure. It is intended to be supported only by its own lift
(3) The ladder operator should remain in constant visual (and if possible, radio) contact with ladder
occupant(s). The ladder operator should remember that the conditions at the ladder tip can vary
greatly and change rapidly from those at the operator's station.
(4) Use extreme caution when operating the ladder beneath overhead obstructions.
Avoid overhead electrical power lines. Ladder or occupant
contact with electrical cables can result in serious injury or death
to ladder occupants, ladder operator and/or bystanders.
(5) Notify the local utility company for assistance when overhead power lines cannot be totally avoided.
(6) Ladder operator should remain at the operator's station during ladder use. No one should occupy
ladder until ladder operator gives authorization.
