Instructor-led discussion of pumper / engine driver-operator topics. Officer selects focus. Topics that fit this sheet include: pump theory (centrifugal pump — impeller, volute, transfer valve, pressure vs volume mode), priming systems, engaging the pump (PTO vs split-shaft), tank-to-pump and tank fill, gauge interpretation (intake, discharge, RPM, pump pressure governor), pumping from booster tank vs hydrant vs draft, drafting setup (hard sleeve, strainer, lift), priming the pump and dry-prime testing, friction loss calculations (FL=CQ²L for various sizes), nozzle pressures (smooth bore 50 PSI handline / 80 PSI master, combination 100 PSI / low-pressure 75 PSI), elevation gain/loss (5 PSI per floor), gated wye and water thief operations, supplying multiple lines simultaneously, supplying master streams, supplying aerials and standpipes, foam systems on the pumper (around-the-pump, balanced pressure, CAFS, eductor), tandem and relay pumping, cavitation recognition, troubleshooting (no water, low pressure, pump won't shift), apparatus inspection per NFPA 1911, EVOC for pumpers (visibility, weight, braking distance), and intersection safety. Reference: NFPA 1002 Ch. 5, NFPA 1410, NFPA 1500, NFPA 1911, IFSTA Pumping Apparatus D/O. Document specific topic covered.

1. 1. Describe the pumper theory or operation discussed.
2. 2. Calculate pump discharge pressure (PDP) for a given scenario.
3. 3. Identify pump panel controls, gauges, and warning indicators.
4. 4. Discuss daily / weekly inspection items per NFPA 1911.
5. 5. Review department pumper SOG and emergency response policy.
