what is needed before employees are allowed to step from the apparatus
Full Stop
Stop sign / Light
Proceed past a red or stop signal or stop sign, but only after slowing down as may be necessary for safe operation
Due Regard
The foregoing provisions shall not relieve the driver of an authorized emergency vehicle from the duty to drive with due regard for the safety of all persons, nor shall such provisions protect the driver from the consequences of his or her reckless disregard for the safety of others
Stopping distance at railroad crossings
the driver of such vehicle shall stop within 50 feet but not less than 15 feet from the nearest rail of such railroad, and shall not proceed until the crossing can be made safely when
- A clearly visible electric or mechanical signal device gives warning of the immediate approach of a railroad train
- A crossing gate is lowered or when a human flagger gives or continues to give a signal of the approach
- An approaching railroad train or other on-track equipment is plainly visible
True Emergency
A situation in which there is a high
probability of death or serious injury to an
individual(s) or significant property loss and
actions by the emergency vehicle driver may
reduce the seriousness of the situations.
Due Regard
This means that while performing similar
duties and under similar circumstances, a
reasonably careful person would act in the
same manner.
responding to true emergencies
DUE REGARD must be used when
SPECIFIC EXEMPTION is taken while
responding to a TRUE EMERGENCY in
the EMERGENCY MODE.

Use of Emergency Mode
Use emergency mode only when
responding to a true emergency
DICE
Decision: decide which way you want to
go.
Intent: signal your intention, let others
know what you are about to do.
Check: check your mirrors, lean forward
in your seat to reduce the blind spot.
Execute: make your merge a gradual
one, do not perform maneuvers that
cause excessive swaying of the
apparatus.
BACKING OF APPARATUS
- Never back unless you have to.
- Use a spotter.
- If you back up, do it slowly.
- Back as if you expect to hit
something. - Keep looking back until completely
stopped. - Your ground guide should position
himself/herself at the left rear of the
tanker where eye contact can be
made with the EVO in the mirror. - If you cannot see the spotter- STOP!
- Use Standard Apparatus
Communication
Stop
Forward or Reverse
Left or Right
Diminishing Clearance
Approaching Intersections
Use extreme caution when traveling
through intersections.
* Remove foot from accelerator and cover
brake while approaching.
* Reduce speed when approaching
intersection.
* Come to a full & complete stop against a
stop signal, if possible.
* If visibility is blocked or unclear always
stop.
* Make eye contact with other drivers and
pedestrians.
RAILROAD CROSSINGS
Stop at uncontrolled crossings, look
and listen
Don’t shift gears on tracks
If you are stuck, ditch the rig
Know the length of your EV and don’t
try to ‘beat’ a train
PHYSICAL FORCES THAT IMPACT
VEHICLE OPERATIONS
- Speed (Acceleration)
- Force/Momentum
- Friction
- Centripetal Force
FORCE AND ACCELERATION (SPEED)
Force = Mass x Acceleration (F=MA)
* ‘The bigger you are, the harder you
hit.’
* ‘The faster you go, the harder you hit.’
FRICTION
- It would be impossible to control a
vehicle without friction. - Friction enables the Emergency
Vehicle to stop, accelerate, and
change direction. - Friction is the resistance to slipping.
- Friction occurs whenever two
surfaces rub together.
Dry Asphalt - COEFFICIENT OF FRICTION
value of 0.8 to 0.9
Wet or Icy Asphalt - COEFFICIENT OF FRICTION
drop to 0.2 or 0.3
