Primary objectives for roadway incident operations include:
p. iv
1) Establish a safe work area.
2) Establish water supply, if needed.
3) Protect environment.
4) Restore normal traffic flow.
5) Keep as many lanes open as possible.
6) Preserve evidence.
“advance warning”
p. v
notification procedures to advise motorists to adjust to temporary emergency traffic control mesaures ahead of them
“downstream”
p. v
direction of traffic moving away from the incident
“work area” / “incident space”
p. v
the area shielded by the block created by apparatus
“upstream”
p. v
direction of traffic approaching the incident
Emergency response on limited-access highways should include ____ because ____.
p. 1
at least 1 unit traveling in each direction to eliminate delays from misinformation.
Units should travel ____ to avoid confusing highway motorists.
p. 1
single-file
How should a vehicle operator act once an incident location has been determined?
p. 1
Act as a slow-moving roadblock by reducing speed from a distance.
If the shoulder must be used for response, vehicle opperators must be aware of:
p. 1
road signs, debris, guard rails, stopped vehicles, standing water.
When should median strip crossovers marked “authorized vehicles over” be used?
p. 1
If the operator can complete the turn without obstructing the flow or traffic in either direction
OR
When all traffic movement has stopped
How should vehicle operators should enter highway access and egress ramps? What is the exection?
p. 1
In the normal travel direction unless the OIC can confirm oncoming traffic has been stopped and that no cars will be encountered.
What should be considered when travel lanes are limited?
p. 1
A designated patient transport corridor.
U-turn access points between Jersey barriers should occur only ____.
p. 1
when necessary for lifesaving measures.
flexible delineator marker/post
p. 1
When crossing through flexible delineator markers, ____ speed and pass at a ____ angle.
p. 1-2
reduce ; shallow
Who takes responsibility for apparatus placement on a roadway?
p. 3
Apparatus driver and OIC.
What effects does proper apparatus positioning have?
p. 3
easy access for other responding resources, establishes safe work area, contributes to effective overall operation.
Who has priority positioning for a roadway incident?
p. 3
Extrication rescourses and transport units.
Where should the first-in engine position?
p. 3
prior to the incident / behind the incident
How should the first-in engine position to positively affect operations?
p. 3
Close enough to provide a hoseline, far enough to allow other units to operate.
“fend-off position”
p. 3
engine placed at an angle w/ the wheels pointed away from the incident, pump panel facing toward the work area
When should all sides of an incident be blocked, ideally?
p. 3
When the incident is near the middle of a street ot at an intersection.
If more units are needed to create a safe work area, where should blocking apparatus position?
p. 4
At least 50 feet behind the first operating unit.
Where should rescue, EMS, and command vehicles position?
p. 4
All within the shielded work area.
Rescue - in front of the first-in engine
EMS - past the incident for rapid egress
Command - past the incident
What if the first-in unit is not an engine?
p. 4
That unit should take the position normally taken by the first-in engine company. Then, the engine company will position behind it.
Where should suppression units position in residential areas when responding with an EMS unit?
p. 5
Position to shield the back of the transport unit or stop short of the address so the unit can pull past.
T/F: Suppression units should remain onscene until the EMS unit has left to transport the patient.
p. 5
True
What should the apparatus driver do after positioning in the fend-off position at a roadway incident?
p. 5
Place flares or traffic cones along the work area that extend downstream and away from the incident.
Personnel placing cones or flares should do so in what manner?
p. 6
Facing oncoming traffic.
Where should the first cone be placed if the incident takes place near a curve, hill, or ramp? Why?
p. 6
Prior to the curve, hill or ramp to warn oncoming traffic.
An apparatus operator may position further away from the roadway incident if ____.
p. 9
if the primary blocking position would expose the engine to fire.
All 3 must occur in order for emergency lights to be turned off:
p. 9
1) daytime
2) all vehicles and emergency apparatus have been moved onto the shoulder
3) traffic is congested and passing slowly
If emergency lights are off, then ____.
p. 9
hazard lights must be on.
How does the human eye react to darkness and red light?
p. 9
The color red blends into surroundings at night abd becomes harder to see.
“glare recovery”
p. 9
the time it takes for the human eye to recover from the effects of glare once light passes through the eye
How long does vision recovery take when the eye moves from light to dark?
p. 9
At least 6 seconds.
How long does vision recovery take when the eye moves from dark to light?
p. 9
3 seconds.
T/F: Engine drivers should keep their headlights on at all times during nighttime roadway incidents.
p. 9-10
False. Headlights should be turned off when not needed to illuminate the scene in order to decrease glare recovery for oncoming drivers.
The ideal combination of lights to provide maximum night visibility:
p. 10
red warning lights on
headlights off
fog lights off
pump panel lights on
rear & front spotlights directed onto a traffic cone
traffic directional board operating
Apparatus should be repositioned during a roadway incident once ____.
p. 11
operations (EMS care, extrications, suppression, etc.) are complete.
Level 1 traffic incident
p. 13
No/minor lane blockage; less than 30 min. impact
Level 2 traffic incident
p. 13
Lane blockages but not full roadway; 30 min. to 2 hours impact
Level 3 traffic incident
p. 13
Entire roadway is closed in any single direction OR more than 2 hours impact w/ significant congestion
