Reckless Disregard
An act of proceeding to do something with a conscious awareness of danger
Negligence
Breach of duty,
failure to perform at the standard required by law
Gross Negligence

Due Regard
Driver/Operators drive with “Due Regard” for the safety of others
Driver Operator most important responsibility is to…..
Operate the apparatus safely during routine driving and while responding to emergency calls
Most common place for a collision to occur
At an Intersection
Seven Basic Causes of collisions
Improper Backing
Reckless Driving
Excesive speed
Lack of Driving skill and Experience
Overloading and Misuse
Mechanical Failure
Driver/operator personal readiness
Drivers should develop a _________ attitude
safety-conscious
A Driver must not put themselves or the public in a position…
where there is no alternative to a collision
What causes Brake Fade
Loss of braking function due to excessive use due to excessive speed
Which NFPA regulation provides guidance on loading hose while apparatus is moving
NFPA 1500
NFPA 1500 provides the following guidance for loading supply hose while driving
Assign at least one member as a safety observer
Close area in which the hose loading is being performed
drive only forward, straddling or to one side of hose at no greater than 5 mph
Do NOT allow member to stand on apparatus while it’s moving
Prohibited by NFPA 1500
FF shall not be allowed to ride the tailboard, front bumper, or running boards of moving apparatus
Most common cause of injury for driver
Slips and fall when entering and exiting apparatus
HEST indicator is
High Exhaust System Temperature
DPF indicator is
Diesel Particulate Filter is filling up with soot
When do you use Regen Inhibit
When apparatus is parked next to dry grass or over other combustible materials
When will automatic regeneration occur
Engine Load, Exhaust temperature and engine speed are within an acceptable range.
Apparatus that use DEF will be equipped with…
Selective Catalyst Reductant
Failure to keep DEF tank full will result in
Reduced Torque output or limit vehicle speed, to the extent of being limited to speed 5 mph and need service from dealer.
Never shut down an engine…
Immediately after a full load operation or when temp gauge shows overheating
Angle of Approach (aerial)
A line from point where front tires touch the ground to the lowest projection at the front of apparatus
Angle of Departure (aerial)
A Line from the point where the rear tires touch the ground to the lowest projection at the rear of the apparatus
Breakover Angle
A line from the point where the rear tires touch the ground to the bottom of the frame at the wheelbase midpoint
When steering, operator should use _______ to keep ________ to a minimum
As much steering as needed to keep weight transfer to a minimum.
Steering should be accomplished in a…
smooth and fluid motion rather than a series of multiple turns
Axle Loading is balanced Side to side and back to front within…
7% from side to side and within axle weight ratings front to back
Driving downhill to prevent engine damage…
Limit downhill speed to lower than maximum RPM
The engine ________ cannot control engine speeds __________
Governor, downhill
Can result in damage for engine speed to be higher than rated RPM
Allowing apparatus to coast out of gear
is unsafe and can be illegal also known as freewheeling, can result in vehicle runaway
Civilian drivers respond better to sounds….
that change pitch
Best ways to get attention of drivers
Short air horn bursts and the constant up and down oscillation of a siren.
At what speed will apparatus outrun the effective range of audible warning devices
50 mph
Multiple emergency vehicles responding should keep this distance between them
300 to 500 feet
Braking Distance
Distance Vehicle travels from brakes being applied until reaching a complete stop
Total Stopping Distance
Sum of drivers reaction distance and braking distance
Reaction Distance
Distance apparatus travels while operator transfers his or her foot from gas to brake
What condition provides for optimal stopping
A paved surface that is flat and dry
Acceleration vs Locked Wheel Skids
Acceleration: Drive Wheels lose traction on road surface
Locked Wheel: Results from braking too hard at high rate of speed
Per NFPA 1901 what GVWR min requires to be equipped with aux braking system
36000lbs of GVWR
Four Types of Aux Brakes
Exhaust Brake
Engine Compression Brake
Transmission Output Retarder
Electromagnetic Retarder
Automatic Traction Control
or ATC
Automatically reduces engine torque and applies the brakes to wheels that have lost traction
Roll Stability Control
RSC
integrated into ABS system with lateral accelerometers that sense when side force causes apparatus to reach roll-over threshold.
Reduces Torque in engine and retarder application
Electronic Stability Control
ESC
Reduce Torque in engine, applies retarder and applies brakes independently to aim the vehicle in the direction that the operator positions the steering wheel.
Distance for backer to be when reversing
8 to 10 feet, on the drivers side mirror
NFPA for apparatus training and testing program
NFPA 1451
Standard for a fire and emergency service vehicle operations training program,
Always have a second person present when….
Working On, Around or under the apparatus
NFPA 1901 specifies this about equipment not needed while driving
must be secured in brackets or contained in a storage cabinet
