important as taking care of patients.
1
Driver Characteristics
Physical fitness
• Effects of medication
• Fatigue
Emotional fitness
• Maturity and stability
• Proper attitude
As a public servant, your actions will
be scrutinized.
1
Safe Driving Practices
• Speed does not save lives; good care
does.
• Seat belts must be worn.
• Learn how your vehicle accelerates,
corners, sways, and stops.
1
Driver Anticipation
• Anticipate the actions of other
motorists and pedestrians.
• Assume actions of other drivers will
cause a collision.
• Use of PA system may add to
confusion.
1
Cushion of Safety
•
•
•
•
Keep safe following distance.
Watch for tailgaters.
Be aware of blind spots.
Use a spotter when backing up.
1
Excessive Speed
• Speeding is unnecessary if patient is
properly assessed and stabilized.
• Decreases reaction time
• Increases stopping time and distance
1
Vehicle Size and Cornering
• Vehicle length and width are critical
factors in maneuvering.
• Vehicle size and weight greatly
influence braking and stopping
distances.
• Always be aware of your position on
the roadway.
• Take corners at the speed that will put
you in the proper road position as you
exit the curve.
1
Weather and Road Conditions
Be alert to changing conditions.
Decrease speed and increase distance in
poor conditions, such as:
• Hydroplaning
• Water on roadway
• Decreased visibility
• Ice and slippery surfaces
1
Laws and Regulations
• Vary from state to state
• EMS drivers have certain limited
privileges.
• These privileges do not lessen drivers’
liability.
1
Warning Lights and Sirens
• Must be responding to an emergency
• Use both audible and visual devices.
• Operate with due regard.
1
Right-of-Way Privileges
• You must not endanger people or property
under any circumstances.
• Know your local right-of-way privileges.
• Exercise them only when necessary for
the patient’s well-being.
1
Escorts and Intersection Hazards
Use of escorts
• A dangerous practice
• Follow escorts at a safe distance.
Intersection hazards
• Most common place for collisions
• Even on urgent calls, come to a
momentary stop at the light.
1
Air Ambulances
Fixed wing
• Interhospital
transfers
Rotary-wing
• Used for
shorter
distances
1
Medivac Operations
Become familiar with local capabilities.
Calling for a medivac:
• Ground transport would take too long.
• Spinal cord injuries, amputations,
burns, diving emergencies, venomous
bites
Notify your dispatcher first.
1
Establishing a Landing Zone
• Area should be hard or grassy level
surface that measures 100' x 100'
(recommended)
• Clear area of loose debris and survey
for overhead or tall hazards.
• Mark landing site with weighted cones
or headlights.
1
Safety Precautions
• Do nothing near the helicopter and only
go to where the crew or pilot directs
you.
• Keep a safe distance away from the
aircraft.
• Stay away from the tail rotor.
• Never approach the helicopter from the
rear.
