Regular practice, classroom study, and organized drills with the aerial appratus shoul include what?
- Knowing and using technical data
- Preparing the device for use
- General positioning of apparatus
- Operating controls
- Using the aerial device with fire streams
- Knowing aerial device uses during rescue
- Inspecting the aerial device
What must a driver/operator understand and be able to use on their aerial apparatus?
-The controls functions, operations, and safeties
- The function and operation of stabilizing power.
- Limitations of the apparatus
- Proper spotting angles
- Maximum load limits
- Safe operating practices
Raising the aerial device consists of a series of motions that include what?
- elevating
- rotating
- extending
- Lowering the device to its objectives
When operating and aerial device one motion is recommended at a time unless what?
- The situation is critical
- The operator is qualified to operate the apparatus in that manner
- Your apparatus is equipped with a system that is designed for multi-use operations
What tasks should the driver operator complete before deploying the aerial device?
-Place the aparatus in proper position
- Apply all parking brakes
- Place apparatus transmission into the proper gear and operate the PTO
- Fully deploy stabilizers
- Switch selector valve from the stabilizer position to aerial device.
Why should full-speed operation of the aerial be minimized, regardless of the skill of the operator?
Large amounts of dynamic stress placed upon the aerial device when the motion is halted.
On most aerial apparatus the hold-down locks release automatically when what happens?
-The PTO s engaged
- The stabilizers are fully deployed
- The selector valve is switched from the stabilizers to the aerial device.
In accordance with aerial device manufacturers recommendations, the aerial device should be positioned approximately _-_inches above the surface of the target.
4-6 inches
Most aerial ladder failures or apparatus overturning accidents involve a combination of what?
Overloading or over-extension of the ladder at low angles of elevation.
Why do some departments supply aerial master stream appliances from two different pumpers?
So that if one pumper loses water, there is not an immediate loss of water to the aerial master stream reducing the chance of damage created by the sudden shut off of water.
What are the keys to operating on a grade?
- Optimum positioning
- Proper stabilization of the apparatus
- Knowing load restrictions for the given grade
Though limitations will vary among manufacturers, most allow full operation in winds up to how fast?
35-40 mph
Manufacturers of several older light duty ladders recommend the use of guy ropes when it is necessary to extend the ladder to how many feet or more?
75ft or more
Loads that involve motion. The include the forces arising from wind, moving vehicles, earthquakes, vibration, falling objects, as well as the addition of a moving load force to an aerial device or structure.
Shock load (dynamic load)
Heat damage to the aerial device may or may not be visible. What are obvious signs of damage?
- discoloration
- disfiguration
- deformed weld
- improper mechanical response of any working portion of the aerial device
The driver/operator must be continually on the lookout for what signs off mechanical trouble or impending failure?
- Leaking fuel
- Leaking hydraulic fluid
- Leaking coolant
- Leaking motor oil
- Overheating of any component
- Unusual noises of vibrations
- Odor of burning fluids
- Drifting of aerial device when raised
- Overloading of electric system
- Gauges indicating abnormality
How often should a driver/operator practice with their aerila apparatus?
At least once a week or at the beginning of every work cycle
