Flashcards in 5031 Traffic Work Zones at Incident Scenes (safety) Deck (24):
What policy number is
Traffic Work Zones at Incident Scenes
A visual indication for approaching motorists to warn of an upcoming roadway hazard.
A safe space or distance between the protected work zone and the moving traffic.
Area from which traffic flow leaves a roadway incident.
Emergent Traffic Zones
Areas of operation that take place on or near active roadways, including, but not limited to:
1. Motor vehicle accidents
2. Vehicle fires
3. Downed power lines
4. Grass/brush fires along roadways
Area from which traffic flow approaches a roadway incident.
TFD personnel shall wear the following forms of high visibility/reflective clothing when working in emergent traffic zones
a. Structural firefighting helmets properly donned at all times
b. Structural firefighting PPE donned prior to beginning work at roadway incidents
involving activities such as fire suppression, standby with hose lines or extinguishers, or extrication activities involving exposure to broken glass and jagged metal
When not wearing structural PPE, TFD personnel shall wear
a high visibility/reflective vest and helmet at all times while working in emergent traffic zones.
TFD personnel may
-Don structural firefighting helmets and high visibility/reflective vests over a department issued uniform or uniform service coat without structural PPE in an emergent traffic zone if s/he will not be involved in fire suppression, standby with hose lines, or extrication assignments that expose them to hazards such as broken
glass and jagged metal
-Wear a high visibility/reflective vest over a uniform service coat when his/her activities at the scene do not warrant the use of structural PPE
TFD personnel who are actively involved in ALS procedures or rendering emergent or
urgent BLS care in emergent traffic zones may
take off his/her structural PPE and/or
helmet if it interferes with or hinders his/her ability to administer patient care.
a. In these cases, TFD personnel are required instead to wear a high visibility/reflective vest while such procedures are performed or while outside of
the medic unit
TFD personnel shall not
a. Operate in an emergent traffic zone wearing only his/her department issued
b. Wear an orange high visibility vest over his/her turnout clothing when involved in active firefighting in an emergent traffic zone
The first arriving company shall park the apparatus in a
block position with the front wheels turned in a direction that points away from the work zone to protect the incident scene, patients and emergency response personnel
Whenever possible, the block position of the apparatus shall be at a
a. Minimum 45 degree angle to upstream traffic AND
b. Sufficient distance to prevent an upstream vehicle from knocking the blocking
apparatus into the work zone or personnel
i. Typically blocking one lane in addition to what is already obstructed will provide this margin of safety
If the incident occurs at an intersection or in the middle of a roadway
TFD personnel shall attempt to block all exposed sides.
When responding apparatus numbers are limited, TFD personnel shall prioritize blocking of exposed sides as follows
a. Block the closest approaching traffic, then
b. Block the highest speed approaching traffic, then
c. Block the highest volume approaching traffic
If a hose line may be needed, TFD personnel shall
park the apparatus so that the pump
panel is downstream and on the opposite side of the oncoming traffic.
At residential medical emergencies, medic units and private ambulances shall
be parked in driveways whenever possible.
For effective incident scene management and to avoid possible confusion when assigning apparatus to positions and tasks, freeway lanes shall be numbered?
from right to left as one faces the direction of travel.
EXAMPLE: Far right lane would be Lane #1; the next lane to the left would be Lane #2
and so on.
The first arriving company shall park the apparatus in a block position with the front
wheels turned in a
direction that points away from the work zone to protect the incident scene, patients and emergency response personnel
The second arriving company shall create a buffer zone by
parking the apparatus 150 to 200 feet upstream of the first apparatus in a block position with the front wheels turned in
a direction that points away from the work zone.
Other apparatus shall be parked
downstream of the incident, if possible.
6. Medic units and/or ambulances may be staged and brought up to the incident scene as
The Incident Commander shall exercise one of the following options if the safety of the
personnel cannot be assured
a. STOP the flow of traffic until the fire department task is accomplished and
scene personnel can move out of the exposed position OR
b. Reduce the traffic flow to a pace that guarantees the safety of scene personnel
The Incident Commander also shall
a. Evaluate the need for identifying a primary and secondary escape route and
communicate these to scene personnel
b. Consider reducing to appropriate levels the number of flashing lights, strobes and headlights on emergency apparatus that are at the roadway incident scene to lessen the potential for vision impairment and/or confusion for motorists
