Operating Procedures for Roadway Incidents Flashcards
DEFINE ADVANCE WARNING
notification procedure that advise approaching motorists to transition from normal driving status to that required by the temporary emergency traffic control measures ahead of them
Define Block
positioning a fire department apparatus on an angle to the lanes of traffic creating a physical barrier between upstream traffic and the work area
Define Buffer Space
the distance or space between personnel and vehicles in the protected work area and nearby moving traffic
Define Downstream
the direction that traffic is moving as it travels away from the incident scene
Define Incident Space
the protected work area at a vehicle-related roadway incident that is shielded by the block from apparatus and other emergency vehicles. Also commonly referred to as Work Area
Define Taper
The action of merging several lanes of moving traffic into fewer moving lanes
Define Transition Zone
the lanes of a roadway within which approaching motorists change their speed and position to comply with the traffic control measures established at an incident scene
Define Upstream
the direction from which traffic is traveling as vehicles approach the incident scene
Define Work Area
also known as Incident Space, the protected area at a vehicle-related roadway incident that is shielded by the block from apparatus and other emergency vehicles
ANSI/ISEA 107-2010?
Requirement of high visibility safety apparel
LCES for IAP
L: Lookouts
C: Communications
E: Escape Routes
S: Safety Zones
How should units respond when they respond together from the same direction?
Single file
When vehicle operators are using the shoulder of the road to respond down they should be aware of:
- road signs
- debris
- guard rails
- oversized vehicles and stopped vehicles
- standing water
Designated median strip crossovers marked “Authorized Vehicles Only” shall only be used when:
Apparatus can complete the turn without obstructing traffic flow or when all traffic movement has stopped
The use of U-Turn access points in “jersey” barriers should only be used when:
It is necessary for immediate lifesaving measures
Lanes should be identified as:
Inside Travel Lane (closest to median)
Middle Travel Lane(s)
Outside Travel Lane (closest to shoulder)
Fend-off position?
Engine company position in a manner that the apparatus is placed at an angle to the lanes, the pump panel toward the work area and the front wheels rotated away from the incident
How far back shall blocking apparatus position from the first operating unit?
50ft
If the first arriving unit is not an Engine Co. on a roadway incident do they assume the Engine Co. blocking responsibility?
Yes, they will position as if they were the 1st Engine, when the 1st Engine arrives they will assume a position behind this unit in a blocking manner
How long should the Buffer Space be?
80ft
How long should the Taper length be?
40ft
The best combination of lights to provide maximum night visibility is as follows:
- Red warning lights on
- headlights off
- fog lights off
- pump panel lights on
- spot lights on rear and front on and directed to a traffic code
- traffic directional boards operating
How much additional delay does one minute of stopped traffic cause?
4 minutes
VDOT Traffic Incident Level 1:
Minor-impact to the traveled roadway is estimated to be less than 30 mins with no lane blockage or with minor lane blockage
VDOT Traffic Incident Level 2
intermediate-impact to the traveled roadway is estimated to be between 30 minutes and 2 hours with lane blockages, but not full closure of the roadway.
VDOT Traffic Incident Level 3
Major-Impact to the traveled roadway is estimated to be more than 2 hours OR the roadway is closed in any single direction; significant area-wide congestion is expected
THE PRIMARY OBJECTIVES FOR ANY ROADWAY INCIDENT INCLUDE:
- Establish a safe operating area
- Provide Emergency Care and Transport
- Establish water supply
- Protect the environment
- Restore normal traffic flow
- Keep as many lanes of traffic open as possible
- Preserve evidence for investigators
- USE ICS to manage resources
From light to dark it takes vision how long to recover, and dark to light?
6secs, 3secs
