Q

Control positions

A

Primary is at the pedestal: be aware of number weight and position of personnel, wind and ice, comms with tip, other people on the turntable
Secondary is at the tip: final positioning, other people on the ladder, belted, water flow reaction, electrical hazards, feet clear

Q

Operating aerial ladders with piped waterways and water towers

A

Operated by remote control (better than FF at the tip) and some have cameras or TIC’s
Make sure pinned correctly

Q

Operating aerial ladders with detachable waterways

A 
More challenging
FF at tip exposed to heat and smoke
Usually no aerial controls at the tip
Can't move much when charged
Loose nozzle can hit FF
Use ropes from pedestal (FF at tip to change pattern, shut down water if you can)
Charge and stop slowly to avoid shock loading the ladder
75* elevation, 80% extended, 80 psi
Don't use a hose with a nozzle attached

16
Q

High wind

A

See mfg load guide, Or dispatch, Or iphone
15-24 small trees moving, whitecaps on ponds
25-31 Large tree branches, whistling from powerlines
32-38 whole tree, feel it when walking
39-54 twigs breaking, cant walk, bld damage

17
Q

Cold weather

A

Hydraulics become viscouse, slowing movements
Metal becomes brittle, shock loading is worse
Ice makes it heavy and slippery, .25” total allowed
Applied grease can help keep it from sticking
De ice with high pressure steam or liquid, must be non corrosive
For weight keep in most stable position inline with chasis
Position with wind to avoid overspray

18
Q

Ice shrugging

A

Slowing extend and retract ladder to remove ice

Won’t work if too much ice

19
Q

Exposure

A

Move, or spray with water if it becomes one (don’t hit guys on the ladder)
Use a handline to avoid damage

20
Q

Signs of heat damage

A 
Discoloration
Disfiguration
Deformed welds
Improper operation
Aluminum aerials have heat sensors
If suspected, remove from service and tested
21
Q

Mechanical failure warning signs

A 
Leaking fuel, hydraulic fluid, oil
Overheating
Strange noise or vibration
Drifting when raised
Gauges giving bad info
Smell of burning fluids
Interlock failure
An unsafe drop in voltage or alarms
Remove FF, bed it, take it out of service
22
Q

Failure of hydraulic pump

A

Operating for a long time can make the oil overheat and cause permanent damage
Use aux pump in intervals

23
Q

Below grade

A

Rescues from hole, trench, cars off an embankement
Most aerials not designed for below grade tip loading
Don’t lift a load but can use as high anchor point
Some have winches on platforms

24
Q

Safety: inspection

A 
Chasis inspected with 1911
Daily inspections
Ventilate when inspecting batteries
Stay clear of moving parts
Don't touch hot surfaces
25
Q

Safety: prepare to drive

A 
Know the owner's manual
Three points of contact
Adjust seat, mirror, medal and steering wheel
Secure compartment doors
Store hose and restrain
Make sure all seatbelted
Stow stabilizers, bed ladder
26
Q

Safety: driving

A 
Only if you are trained
Use a spotter when backing
Don't speed
Mind low bridges and OH obstructions
Obey traffic signals
Look ahead and anticipate
Turn off aux braking in bad weather
27
Q

Safety: positioning

A 
Always use a spotter
Only on firm surfaces
Only on approved slopes
Within reach of aerial
On corner if possible
Away from falling debris
Use warning lights if in traffic
Never on railroad or active runway
28
Q

Safety: stabilizing

A

Read your manual
Firm surfaces only
Only on approved slopes
Use parking brake, aux front wheel lock and wheel chocks
Clear from powerlines
Clear stabilizer area and use ground pads

29
Q

Safety: operating

A 
Operate controls from platform, not ground
Only put FF on tip if you have to and only with someone on the turntable controls
Communicate with tip before moving
Mind load chart limits
If ice, use mfg reduced capacity
Mind wind
Short jacking ok if careful
Don't make contact with structure
Don't put over roof that might self vent
30
Q

Safety: climbing

A

Use ladder belt
Three points of contact
Don’t hold hand rails or rungs if extending/retracting

31
Q

Safety: water mgt

A

Mind reduced load limits
Prevent water hammer
Change direction slowly
Drain before retracting or removing caps

32
Q

Safety: strategy

A

Rescue victims upwind
Aim above victim and lower to them
Mind debris or collapse
