When positioning on a highway at a nighttime incident, headlights should be - answer -Headlights should be placed in low- beam without flashing. When parked on a longitudinal grade, DO NOT... - answer -...do NOT extend or retract the aerial device over the side of the apparatus.
As aerial extension increases... - answer - Aerial loading must deacrease. Portable lights mounted on an Aerial Apparatus range - answer -300-1000 watts Three considerations for proper distancing between target and the apparatus? - answer - -Maximum Stability -Best Climbing Angle -Adequete Extension NFPA 1901 - answer -Standard for Automotive Fire Apparatus
When rescuing victims off a parapet-style roof, it may be necessary to - answer -rest a roof ladder against the aerial ladder. "Knee-Sit" carry is best suited for - answer - Conscious, adults victims who have trouble moving on their own. Blitz attack master streams should only flow until - answer -flows until the fire is controlled or knocked-down. The apparatus may need to be short-jacked when.. - answer -..when access for full stabilization is restricted. Order in which the stabilizers are raised is unimportant. (T or F) - answer -False, it is unimportant in which order these are raised.
Stabilizers are required to prevent what from happening? - answer -To prevent the apparatus from tipping as the aerial device is extended. Most aerial device manufacturers allow full operation of their equipment in winds of up to: - answer -40 mph is the max wind speed. Markers and Sensors can help ensure what alignment? - answer -These help ensure alignment of lowering the ladder into its cradle. the hold-down locks are released when.. - answer -..when the selector valve switch is placed in the aerial device position.
Correct order for lowering a telescoping aerial ladder. (5 steps) - answer -1. Remove personnel
Four factors that affect the choice of a type of aerial apparatus - answer -1. Amount of equipment the apparatus needs to carry
3 service tests for aerial apparatus - answer - Pumping, Priming and pressure control test. Following engine speed and vacuum test, to prepare the aerial apparatus for the remaining test - answer -make the pump operational. The driver/operator will often be required to perform (tests) - answer -Service Test (required to be done by whom?) Three critical items that should be included on an aerial apparatus daily record - answer -Tire Inflation Pressure, "Inspected by" Column, and Lubricant levels. To reduce stress when approaching from the downhill side, the driver/operator can -
answer -Stop short of the building with the aerial device operated over the cab. As aerial extension increases - answer -Aerial loading must decrease An aerial apparatus is most stable when the aerial device is operated - answer -directly over the front or rear of the vehicle Three safety requirements when responding to aircraft incidents - answer -1. Position upwind
The purpose of a blitz attack is to - answer - Immediately stop the progress of the fire in the area of origin The 75-80-80 rule applies to - answer - Detachable waterways (rule) Two things to remember when ventilating an upper-story window from an aerial device - answer -1. Position the aerial slightly above the upwind side
Four pre-service tests for aerial apparatus - answer -1. Hydrostatic Test
When protecting exposures using solid stream - answer -never direct elevated streams into natural ventilation openings. To minimize the risk to responders, nozzles on detachable waterways should be operated
Periodic Tests should include - answer - Instruments and Gauges When working near overhead lines, you should try to maintain a distance of at least - answer -10 feet of distance from these items. When drafting from a static water source, try to select the source that allows - answer - Minimum amount of lift Two features that provide automatic locking capabilities - answer -Holding Valves and Interlock The apparatus may have steering system problems if the steering wheel can be rotated (without moving the front tires) - answer - More than 10 degrees of movement.
Tracking engine performance over time requires data collected in what? - answer - Collected in fuel, oil, and mileage record. Service Tests are conducted by - answer - Done by technicians assisted by the driver/operator. Type of water delivery system on an aerial device specifically designed for the deployment of ELEVATED master streams is a - answer -Elevating water tower system (delivery) Which type of pre-piped waterway system can be found on most new aerial ladders? - answer -Telescoping waterway (pre-piped)
Relay apparatus may discharge air when a line is being charged with water through - answer -A bleeder valve When positioning the aerial apparatus on a thin-skinned paved surface, driver/operators may need to use - answer -Additional cribbing One advantage that fog streams have over solid streams is that they - answer -Are better at breaking up water for steam conversion Two advantages of inverters on aerial apparatus - answer -Low operation noise and efficiency
