Answer 2

. The major components are the fuel injector and lines, the catalytic converter and the fuel evaporation system (which includes the fuel tank).

Question 3

1. Catalytic Converter
   The catalytic converter was designed to reduce hydrocarbon and carbon monoxide emissions before they reach the atmosphere. Tremendous heat is generated in the converter as the catalytic reaction takes place; normal internal temperatures of the catalytic converter can rise to somewhere between 1300 and 1600 degrees F while normal outside surface generally reaches the neighborhood of about 1000 degrees F.

Question 4

This sealed fuel system concept is the primary design used in vehicles presently being manufactured. The intent of this system is to prevent fuel vapors from leaking from this sealed network. The fuel tank cap is designed to prevent passage of gasoline vapors directly into the atmosphere. It incorporates a vacuum relief set-to operate at approximately 3/8 pounds per square inch and a pressure relief valve set to open at approximately one pound per square inch.

Question 7

If members must approach an extensively involved vehicle from the rear and tank rupture does occur, a fire ball will likely erupt from underneath the back bumper and out the sides of the rear wells and the rear fenders. To protect the firefighters on the first one and one-half inch line in this situation, the second one and one-half Inch line should be deployed to the tank area utilizing a wider fog pattern to offer limited additional protection and allow members the opportunity to back out of immediate danger.

Question 10

Motor
During a vehicle fire involving an EV, electrical shock should not occur because the high-voltage of an EV does not use the earth as s ground. A firefighter standing on the ground does not complete a circuit when a stream of water hits an EV. However, there is still a possibility that by touching certain electrical components an electrical shock could occur.

Answer 12

A telltale sign of an Electric Vehicle is the international orange color associated with the wiring system that provides the electric power. This wiring is usually bundled and runs along the lower frame or beneath the seats along the floor boards of an Electric Vehicle.

Question 13

As with any electrical system the capacitors hold stored energy, this energy must be “dumped” for the system to be considered completely de-energized. Because of this there is a delay of between 5 and 10 minutes between the time the power is cut and the system is de-energized. For this reason it is imperative that the power to an electric or hybrid vehicle be cut immediately upon arrival of an accident or vehicle fire.

Question 37

and, as temperatures increase, images are shown in YELLOW and RED. In order to produce images that better distinguish between objects in the overall temperature range, the TIC will automatically operate between what’s called LOW and HIGH sensitivity modes. The HIGH sensitivity mode operates up to approximately 300°F. When temperatures rise above 300°F, the TIC will automatically switch to the LOW sensitivity mode, allowing a better image to be produced.

Question 53

The Reveal FirePRO has three different modes that have been optimized for First Responders. • Fire – Displays an image in shades of BLACK and GRAY which turn bright ORANGE/RED when areas of extreme heat are present. This mode is specifically designed for location HOTSPOTS in fire during 360 size – ups and overhaul. • Survey – Is optimal for helping locate downed firefighters or victims during search and rescue. This mode has a monochromatic filter of different shades of BLUE which turn WHITE around warmer areas. • Auto – Also referred to as color-mode, this is the TIC’s demonstration mode and is bestsuited for classroom use. It highlights areas of heat in RED with colorful borders as the temperature decreases. It is present simply to demo thermal imaging to third party observers and is seldom used in the field.

Question 55

If the "Ready" light on the dash is illuminated, then there is a possibility that the converter will supply power to the high voltage control module and high voltage power will still be running through the orange cables. This makes it mandatory to check the ready light on the dash to ensure that the high voltage is shut down. Cutting the battery cable alone will not ensure that the vehicle is safe from high voltage hazards.

Question 111

Standard Operating Guidelines for Response to Incidents Involving Streetcars Traction power sub-stations (TPSS) supply the catenary system. They take in 13,000v AC from PEPCO, step it down to 750 volts and covert it to DC voltage. The catenary lines are supported over the rails by catenary poles at a height of approximately 20 feet from grade.
