1-10.10 Operating with Personnel on the Aerial Device
Figure 1-15: FAMA38 and FAMA40 Warning Labels
FAMA38, FAMA40
Follow these practices when operating on you aerial ladder.
•
Never allow people to climb, ride or work on your aerial device unless they are thoroughly trained in safe
operation and the importance of using the three points of contact method of climbing.
• Personnel climbing with equipment must have that equipment tethered to themselves in a way that allows them
full use of both feet and both hands.
• Never elevate or rotate the device unless personnel on the ladder or in the platform are secured to a structural
feature with a ladder belt and tether.
• Never extend or retract with people on the ladder. If you do so you may crush their hands, feet, or other body
parts.
1-10.11 Climbing the Aerial Ladder
Climb your aerial ladder if you are climbing with the ladder at a steep angle, using three points of contact. Grasp the
rungs as you climb. Grasping the rungs has several safety advantages over holding onto the rails:
•
Your hands have more holding power when they are grasping a horizontal bar than when they are grasping a
vertical feature.
• If your feet slip and you are holding onto the rails, your hands may slide down the rails, and you may fall. If you
are holding on to the rungs, it is more likely that your hands will have enough grip force to help you recover.
• If your feet slip and you are holding onto only one rail at the time, the weight of your body will be offset from your
line of grip and your body will twist. If you are holding onto the rung, your grip force is lined up with your body,
and your chance of staying in control is much greater.
1-10.12 Aerial Water Flow Operation
1-10.12a Aerial Water Monitor Operation
Your aerial device may include the option to flow water through a pre-piped telescopic waterway and out a water
monitor. The reaction force created by the water leaving the water monitor nozzle is very great, and increases with
the pressure and the flow rate. This reaction is similar to the reaction you get from holding a hand line. For this
reason, be very careful when operating your aerial water monitor. Begin with the nozzle pointed in-line with the
ladder, open control valves slowly, and change nozzle direction slowly. Sudden changes in flow will cause the ladder
to whip.
Pinch Hazard.
Keep feet on folding
steps.
Keep hands off rungs.
Moving rungs can
pinch and crush.
