Flashcards in Chapter 3 - Apparatus Safety and Operating Emergency Vehicles Deck (24)
Fire apparatus driver/operators are responsible for __________, _______, and _____ to and from the scene of an incident.
>The safe transport of firefighters, apparatus, and equipment
If the driver/operator is neligent in the operation of an emergency vehicle and is involved in a collision, both the ________ and the _________ may be held responsible.
Jurisdiction he or she represents
______ is usually found when the driver/operator has been found guilty of a gross violation of standing laws, policies, or ordinances.
A fire apparatus driver/operator should maintain ___________ in order to lower the chances of being involved in a collision with an object, pedestrian, or other vehicle.
In general, fire apparatus collision are grouped into seven basic causes, which reflect the lack of due regard and situational awareness.
1) Improper Backing
2) Reckless Driving
3) Excessive Speed
4) Lack of driving skill and experience
5) Overloading and misuse
6) Mechanical Failure
7) Driver/Operator personal readiness
In ___ percent of all collisions, the driver/operator was not aware of a problem until it was too late to correct.
After a driver/operator continues to ignore an empty DEF tank, the apparatus may be limited in speed to __ mph and will need service from the dealer.
Shutting down an engine without sufficient cool down may result in the following:
>Immediate increase of engine temperature from lack of coolant circulation
>Oil film "burning" on hot surfaces
>Damage to heads and exhaust manifolds
>Damage to the turbocharger that can result in seizure
Angle formed by level ground and a line from the point where the front tires touch the ground to the lowest projection at the front of the apparatus.
Angle of Approach
Angle formed by level ground and a line from the point where the rear tires touch the ground to the lowest projection at the rear of the apparatus
Angle of Departure
Angle formed by level ground and a line from the point where the rear tires touch the ground to the bottom on the frame at the wheelbase midpoint
Poor weight distribution can make a vehicle handling unsafe, such as the following:
>Too much weight on the steering axle can cause hard steering and can damage the steering axle and tires
>Under-loaded front axles can make the steering axle weight too light to steer safely
>Too little weight on the driving axles can cause poor traction
>The drive wheels may spin easily.
It may take __ to __ times greater distance for a vehicle to come to a complete stop on snow and ice than it does on dry pavement.
3 to 15
At speeds about __ mph, and emergency vehicle may outrun the effective range of its audible warning devices.
In some instances, increasing the speed of an apparatus by __ can decrease the audible distance by ___ feet or more.
When more than one emergency vehicle is responding along the same route, they should travel at least ___ to ___ feet apart.
300 to 500 feet
The time needed to stop the apparatus or perform evasive maneuver at the current rate of speed is ________.
Visual Lead Time
The ___________ is the distance the vehicle travels from the time the brakes are applied until the apparatus comes to a complete stop.
The ____________ is the sum of the driver/operator's reaction distance and the vehicle's braking distance.
Total Stopping Distance
___________ is the distance the apparatus travels while the driver/operator transfers his or her foot from the accelerator to the brake pedal.
Some of the most common causes involving driver error include the following:
>Driving too fast for road conditions
>Failing to anticipate obstacles
>Improper use of auxiliary braking devices
>Improper maintenance of tire air pressure and adequate tread depth
NFPA 1901 requires that all apparatus with a GVWR of _____ lb or greater be equipped with an auxiliary braking system.
There are four types of auxiliary brakes to aid the foundation brakes in slowing the vehicle.
>Engine Compression Brake
>Transmission Outer Retarder
