Daily records documents should cover maintenince checks that could _______ ; also should identify _____ - Correct
Answer checks that could affect daily apparatus performance such as battery, coolant level, fuel levels, pump valves,
and tires; specific apparatus by unit identification number, (organized according to how the inspection is generally
preformed, have a remake column for notes on specific problems)
Engine Speed test steps - Correct Answer 1. Ensure running at same speed rated for as was new with an empty tank
2. Can be tested using tachometer on engine or handheld tachometer/revolution counter
3. If doesn't pass stop all testing until fixed
4. On closed road or open highway bring to max speed then back down to normal speed, then compare test to results
to new
Equipment needed for Fire pump service test? - Correct Answer Deluge gun: for high volume flows;
Exterior Test Gauges: Verifies correct readings capable of reading 0-30 inch Hg for intake and 0-400 Psi discharge
unless compounds then 0-600 Psi;
Forms & Flow Tables: to record test results;
Tachometer: verifies engine speed;
Smoothbore tips: to match volume being pumped;
Pitot tubes: to measure velocity of water had knife edge and air chamber rated at least 0-600 Psi;
Ropes,chain, & test stand: for securing test nozzle
Fire Pump service test should be done with what two sources of water? And which source is preferred as a true test
of pumps ability? - Correct Answer Hydrant & Static; Static
Fuel, Oil, and Mileage Records are Helpful for ______; In larger departments and apparatus maintenance
organization or on staff apparatus mechanic may perform these documentations - Correct Answer tracking engine
performance based fuel consumption and for ensuring oil and oil filters are changed
Gauge test steps - Correct Answer Check flowmeter and discharge meter to ensure accurate discharge pressure
