CCRE - Pumper 2023 with complete solution

The benefits of an apparatus-mounted generator on a fire apparatus is that it can provide 50 kilowatts, whereas a portable generator can only produce: 5 Kilowatts It's recommended that fuel, oil, and mileage records be updated: As determined by the jurisdiction Traveling at high speeds on a curvy road may cause your fire apparatus to: Leave the road surface and roll over. You should NEVER back a fire apparatus: if you don't have at least one spotter. When performing the serpentine exercise you would be penalized for: hitting or brushing one of the markers For safety reasons, hand lines with solid stream nozzles should not be operated above: 65 psi Bouncing water off the inside walls of the nozzle bore to create a fog pattern is called: periphery deflection Determine TPL for a hose assembly in which TWO 700' sections of 2 1/2" hose and ONE 700' section of 3" hose with 2 1/2" couplings are siamesed together to supply 300' of 3" with 2 1/2" couplings. Flow is 200 GPM. SHOW WORK. 14.08 psi TPL: 500' of 4" wyed into two 2 1/2" attack lines that are 200' long. Each attack line is flowing 250 GPM. SHOW WORK 60 psi You figure pressure loss in a single hoseline flowing 350 gpm to 45 psi. Then, the layout is altered by adding an appliance, and the nozzle is taken to the sixth floor of a burning structure. the FL for this new layout is now: SHOW WORK 80 Psi Using the condensed Q method, the friction loss for 500 feet of 3 inch fire hose flowing 300 gpm is? 45 psi Best type of strainer to use in a shallow stream is a: Floating strainer As salt water or water containing certain chemicals can corrode the apparatus pump, you should: Flush the pump with fresh water after using it. Hard suction hoses are best used with hydrants having a positive pressure of at least 150 psi. TorF False Hard suction hoses are best used: for drafting from static water sources If you need to draft from a static water source, you primary consideration should be the: Amount of required lift When an intake line is being charged with water, a relay pumper must have: A bleeder valve to discharge air Hard suction hoses are noted for their: Resistance to collapsing One of the major disadvantages of large diameter hoses is: That they are hard to handle The SERIES/PRESSURE position gives you maximum pressure for a short period. TorF. True When a dry supply line is being charged, it is important to open the: Bleeder valve The Pump whose rotor is mounted off-center is the: Rotary vane positive displacement pump When controlling pump valves, push-pull handles: Can accurately control line pressure and be locked into place When using a standard fog nozzle with Class A foams, little or no performance improvement has been shown in concentrations over: 0.5% Foam in foam induction system is drawn into the system through the effect of: A venturi When assembling a portable foam induction system, monitor the use of foam sediment in the educator. TorF Flase When assembling a portable foam induction system, all of the following apply: 1. Ensure the eductor rating matches the nozzle flow 2. Ensure the eductor setting matches the foam concentrate 3. Prepare enough concentrate for the duration of the incident The correct hose layout for the FDC at a property with a sprinkler system should be: a minimum of two 2 1/2" hoselines or one 3" hoseline
