Roadway Incidents Flashcards
The primary objectives for any roadway incident operation involve the following actions:
▪ Establish a safe operating area (i.e., work area) to prevent emergency worker injuries.
▪ Provide emergency care and transportation for the sick or injured.
▪ Establish a water supply.
▪ Protect the environment.
▪ Restore normal traffic flow.
▪ Keep as many traffic lanes open as possible.
▪ Preserve evidence for investigators.
▪ Use the Incident Command Systems to manage resources
Vehicle operators should only use designated median strip crossovers marked “AUTHORIZED VEHICLES ONLY” when they can?
complete the turn without obstructing the flow of traffic in either direction or when all traffic movement has stopped.
Vehicle operators should enter highway access and egress ramps in the normal travel direction unless the unit officer can confirm that ?
oncoming traffic has been stopped and that no civilian vehicles will be encountered on the ramp.
The use of U-turn access points between Jersey barriers presents an extreme hazard and should occur only when…?
necessary for immediate lifesaving measures.
________ _ _________ ____ ______ _______fire and EMS crews should avoid crossing lanes of traffic on foot, especially lanes with traffic moving in the opposite direction from the lanes where their apparatus is parked.
Unless a roadway is completely shut down
Lane designations
Lane 1 = inside travel lane;
Lane 2 = middle travel lanes;
Lane 3 = outside travel lane
Drivers should place blocking apparatus at least __ __ behind the first operating unit to create a safe work area.
50 ft
If an incident requires personnel to channel traffic around a curve, hill, or ramp, they should ….?
place the first cone or flare prior to the hill or curve.
When exiting their apparatus, personnel should perform the following tasks:
- Don appropriate protective clothing or traffic vests.
- Ensure adjacent traffic has stopped or slowed.
- Exit on the work-area side of the apparatus, if possible.
- Ensure their travel path is clear of debris or other hazardous obstacles.
Unnecessarily closing or prolonging traffic lane closure greatly increases…?
the risk of a secondary incident occurring in the traffic backup
Minor Impact to the traveled roadway estimated to be less than 30 min with no lane blockage or with minor lane blockage.
Level 1
Intermediate Impact to the traveled roadway estimated to be 30 min to 2 hr with lane blockages but not full roadway closure.
Level 2
Major Impact to the traveled roadway estimated to be more than 2 hr, OR the roadway is closed in any single direction; significant area-wide congestion is expected.
Level 3
Length of Taper space
120 feet
Buffer Space
