Nova Roadway Ops Flashcards
Advanced warning
Notification procedures that advise approaching motorists to transition from normal driving to that required by the temporary emergency traffic control measures ahead
Block
Positioning a fire department apparatus on an angle to the lanes of traffic creating a physical barrier between upstream traffic and work area
Buffer space
The distance or space between personnel and vehicles in the protected work area and nearby moving traffic
Downstream
The direction that traffic is moving as it travels away from the incident scene
Incident space
The protected work wares at a vehicle related roadway incident that is shielded by the block from apparatus and other emergency vehicles. Also know as WORK AREA.
Taper
The action of merging several lanes 9f moving traffic into fewer lanes of moving traffic
Transition zone
The lanes of a roadway within which approaching motorists change their speed and position to comply with the traffic control measures at an incident scene
Upstream
The direction from which traffic is traveling as they approach the incident scene
Work area
Also known as incident space. Area of protection for working personnel

When should a U-Turn point in a “ Jersey” wall be used?
Only when situations are necessary for immediate life saving measures. And traffic can be slowed or stopped.
How is an incident scene set up?
Advanced warning, taper zone,buffer space, work area

120 feet
How much room should be left for the buffer space?
80 feet
Where should the first engine position?
Prior to the incident allowing enough room for additional apparatus but close enough for hose line protection
How should this unit be positioned?
Placed at an angle to the incident with the pump panel towards the work area and front wheels rotated away from the incident
If conditions exist how far back should additional blocking apparatus be staged?
50 feet behind the first operating unit.
If possible where should the rescue company park?
Between the first arriving engine company and the incident working area
Where should ems units park?
In front of the incident within the working zone with an exit point once loaded with a PT.
When setting up taper and buffer space you should increase the allotted space for highways when speeds exceed 55mph?
True. Lengthen the zones as needed for conditions present.
When setting up around areas of hills or sharp turns what should be done?
The first cone or flare should be placed prior to the hill or curve to warn vehicles. The rest should be set up as normal.

75 feet
From light to dark recovery takes how long?
Atleast 6 seconds

Yes but reduce your speed and watch for any objects that may cause damage to the rig.

4 minutes
On a roadway incident the apparatus should be positioned to block______ travel lanes wider than the incident?
At least one
