Question

Brake Lag Distance

Answer 1

How far the vehicle travels from the time the brakes are applied and the vehicle begins to slow down.

Answer 2

If you were faced with a 6% grade that went for a total distance of 6 miles and if you did not use any braking action during your decent. With a vehicle with a GVW (gross vehicle weight) of 38,000 pounds your speed would climb to 238 mph

Answer 3

This method works by allowing the vehicle to speed up to the desired or posted safe speed then applying the brakes and slowing the vehicle down 5 to 10 mph below the posted speed. Then allowing the speed to pick up and the process is repeated. By applying the brakes in this method there is time to allow the brakes and the brake drums to cool to help control heat buildup as well as to reduce the chance of brake fade.

Answer 4

Four Second Rule - Keep a separation of at least four seconds between the EV and the vehicle being followed.

Answer 5

First-Arriving Engineer goes straight to the hydrant closest to the FDC connection and establishes a water supply. – Your tactical decision of whether or not to Tandem Pump will be based, in part, off of your incoming pressure from the hydrant. * < 100 PSI hydrant pressure = Tandem

Answer 6

The intake pressure from the hydrant and the total number of floors of the building, will determine the need for a Tandem Pumping operation.

Answer 7

position and get supply

Answer 8

2nd arriving will position to supply the FDC and the 1st arriving will supply them.

Answer 9

– Position and prepare to supply the FDC – Communicate with the First-Arriving Engine for hose connections and pressure needs – Overcoming elevation pressure in a high-rise will likely require 2 engines (in Tandem). If it is determined that a Tandem operation is not needed, the second-arriving engine crew will stay together for another assignment – First-Arriving Engineer should notify the Second as quickly as possible to the needs for a Tandem operation or not

Answer 10

PDP will be 10 PSI below the rating of that pump (referred to as building pressure/pressure marked on the placard).

Answer 11

– There is no need to supply the full “building pressure” if the fire pump can handle the pressure and volume needs. Pumping 10 PSI below, will allow the fire pump to do what it’s designed to do. – But be PREPARED to throttle up to that “building pressure” in case the building fire pump fails or is unable to keep up with the volume demand. – *Notify Incident Command immediately if your pumper takes over/supplements the building pressure/volume needs.

Answer 12

You must take steps to prevent your pump from overheating

Answer 13

Lanes are numbered from the outside lane (lane adjacent to the shoulder - Lane 1) sequentially to the inside lane (lane adjacent to the median).

Answer 14

The area where temporary traffic controls are established to create a safe and effective work area in which we can render aid to victims, provide access to transport and tow vehicles, and efficiently divert traffic around the scene. Specifically, the TTCZ includes the following: the taper and advanced warning area, the work area and the termination zone.

Answer 15

Notification procedures that advise approaching motorists to transition from normal driving status to that required by the temporary emergency traffic control measures ahead of them. This is primarily in the form of blocking apparatus but can also include other early warning devices such as cones or flares.

Answer 16

Positioning a fire department apparatus at an angle to the lanes of traffic, or parallel to the lanes of traffic creating a physical barrier between upstream and lateral vehicle traffic. Physical barriers can be established parallel (or lateral) to the work area

Answer 17

The action of merging several lanes of moving traffic on the upstream side of the incident into fewer moving lanes. This is accomplished by emergency vehicles (fire, police, and/or DOT) and cone placement.

Answer 18

Cones that extend from the taper cones along the lane striping to extend the temporary traffic control zone to its termination. Striping cones can be used with some discretion and may not be needed along the lateral side of the incident if using a lateral blocking apparatus. However, cones may still be needed from the lateral blocking apparatus to the termination zone. Caution: cones will not stop any vehicle from entering Temporary Traffic Control Zone

Answer 19

Placement of the tailboard on the upstream side with front bumper to the left, downstream side, typically at a 45-degree angle across two (2) lanes (lane plus one

Answer 20

Placement of the tailboard on the upstream side with the front bumper to the right, downstream side, typically at a 45-degree angle across two (2) lanes

Answer 21

Placement of apparatus parallel to one (1) side of a work zone accident, typically in normal travel lane

Answer 22

When possible, angle the apparatus at 45-degrees away from the shoulder/curbside and create protection from upstream traffic as a first priority. Next, park apparatus along the lateral side of the incident to protect from traffic being directed into the scene due to secondary collisions. This will direct motorists around the scene while protecting the work zone. Apparatus positioning must also allow space for other incoming fire apparatus, aid cars, medics, and tow vehicles. Apparatus must also provide enough protection space in the event of a vehicle colliding with a blocking apparatus.

Answer 23

Members should don their protective ensemble and their traffic safety vest prior to all responses on roadways. During fires, visibility is obscured for many different reasons requiring increased vigilance by all members on scene. * Safety vests are optional during firefighting operations and should only be worn if fire retardant. * Safety vests should not be worn if they could become an entanglement hazard

Answer 24

* If firefighting operations are anticipated to be conducted on LARs, every opportunity should be taken to position the apparatus as to provide the maximum protection for the engineer operating at the pump panel. This may include positioning the front of apparatus opposite from the direction traffic is being diverted and extend the overall distance of the blocking apparatus from the work zone.

Answer 25

Drivers should turn the front wheels away from the firefighters.

Answer 26

If the motor vehicle accident is located in the middle lanes, it shall be the policy of Zone 3 Fire Departments to strongly consider a 3rd fire apparatus to block at 45 degrees on the upstream side of the incident to divert traffic across multiple lanes (see Figure 4). With two (2) apparatus at 45-degrees and one (1) apparatus lateral, traffic will be traveling around one side of the incident only and keeping a safe TTCZ for all personnel in and around the work zone.

Answer 27

between 2 - 25mph snow up to 4' deep or icey roads

Answer 28

Apparatus Operators that are with their vehicle at the incident shall activate the air horn for five seconds followed by a five second pause, then repeat two more times. 5-5-3

Answer 29

Arithmetic Mathematics and Hydraulics Acquiring and Interpreting Information Applies and Maintains Apparatus, Tools, Technology and Equipment Decision Making/Reasoning Effective Communication Integrity, Honesty and Ethics Problem Solving Responsibility and Commitment Safety Self-Management Teamwork (Participation)

Answer 30

Places engine safely, considering flow of flammable liquids, away from bumper explosion when vehicle is on fire whenever possible. * Keeps engine approximately 75 to 100 feet from vehicle on fire.
