Eight modules from pump theory to advanced practical
Work through the modules in order the first time. After that, use the academy as a targeted review system: weak module → drill → calculator/scenario → practice exam.
Each module pairs a short lesson with a station drill and a knowledge check. Mark it complete only after you can explain and perform the objective.
1Pump theory & pump-panel orientationKnow what the pump is doing before touching the throttleNot complete
Lesson
The operator should understand the water path from tank/intake through the pump to each discharge, and recognize the function of common gauges, valves, pressure-control systems, primer, drains, cooling features and tank-fill/tank-to-pump controls.
Centrifugal fire pumps create flow by imparting velocity to water and converting that energy to pressure. Pump performance depends on available supply, engine power, pump condition and discharge demand.
Know this cold
Trace tank-to-pump, intake, pump and discharge flow paths
Know compound/intake vs discharge gauge information
Understand pressure governor or relief-valve purpose
Recognize cavitation and overheating warning signs
Knowledge check: What does a falling intake pressure with increasing discharge demand most directly tell the operator?
Complete the lesson, perform the drill, then mark the module complete.
2Fireground hydraulicsPDP, friction loss, nozzle pressure, elevation and appliancesNot complete
Lesson
Build every pump-pressure problem from components: Pump Discharge Pressure = Nozzle Pressure + Friction Loss ± Elevation + Appliance/System Loss. Use department hose coefficients, nozzle data and SOP allowances.
For friction loss, the common training relationship is FL per 100 ft = C × Q², where Q is flow in hundreds of GPM. Total hose friction loss is then multiplied by hose length in hundreds of feet.
Know this cold
PDP = NP + FL ± EP + appliance/system loss
Q = GPM ÷ 100
Elevation rule of thumb: about 5 psi per 10 vertical feet
Calculate each branch separately in split-line/wye operations
Knowledge check: A hose stretch is made longer but flow, nozzle and elevation stay the same. What must generally happen to PDP?
Complete the lesson, perform the drill, then mark the module complete.
3Pump engagement & tank-to-hydrant transitionGet water moving, then make the supply sustainableNot complete
Lesson
Engage the pump only using the apparatus manufacturer and department sequence. Confirm pump engagement, establish tank water when appropriate, set the initial discharge safely, and monitor tank level and engine/pump indications.
When transitioning from booster tank to a pressurized source, coordinate the hydrant opening, manage the intake valve, maintain discharge pressure, refill the booster tank as appropriate, reset pressure control, and continuously watch residual pressure.
Do not allow water supply changes to surprise the attack crew
Knowledge check: During a tank-to-hydrant transition, what is the operator trying hardest to avoid at the attack line?
Complete the lesson, perform the drill, then mark the module complete.
4Attack lines, wyes & master streamsCalculate the demand and control multiple dischargesNot complete
Lesson
For multiple discharges, calculate the pressure requirement of each evolution, pump to the highest required discharge pressure, and gate lower-pressure lines as needed. Track the total GPM because supply capacity and pump load depend on combined flow.
Wyes and remote master streams add complexity because supply hose, appliance losses, branch hose and nozzle demand all interact. Break the evolution into sections instead of trying to memorize a single shortcut.
Know this cold
Highest-pressure discharge usually governs pump setting
Total GPM matters to water supply
Calculate branches independently
Master streams require correct nozzle pressure/flow and secure deployment
Knowledge check: Two discharges require 145 psi and 175 psi at the pump. What is the normal strategy?
Complete the lesson, perform the drill, then mark the module complete.
5Water supply & hydrant managementRead residual pressure before the system runs out of marginNot complete
Lesson
A reliable pump operator watches static/residual intake information, hydrant behavior, supply-line condition and changing incident demand. The number on the discharge gauge means little if the intake side is collapsing.
Hydrant-flow and percent-drop concepts help estimate remaining system capacity, but they are decision aids—not permission to drain a system below department or utility limits.
Know this cold
Static vs residual pressure
Monitor intake pressure as lines are added
Recognize kinks, partially open valves and supply restrictions
Estimate additional capacity conservatively
Coordinate additional supply before conditions become critical
Knowledge check: Why does residual intake pressure matter when additional lines are opened?
Complete the lesson, perform the drill, then mark the module complete.
6Drafting & relay pumpingMove water when the hydrant cannot do the jobNot complete
Lesson
Drafting requires an airtight suction path, suitable water depth/quality, correct strainer placement, priming and careful monitoring of lift and pump performance. Small air leaks can prevent or destabilize a draft.
Relay pumping is a pressure-and-flow problem across distance. Each pumper must provide enough discharge pressure to overcome supply-hose friction and elevation while delivering the desired intake pressure to the next engine.
Know this cold
A draft must be airtight
Understand lift and site limitations
Prime only as required by the apparatus procedure
Relay PDP includes supply-line FL, elevation and target intake pressure
Knowledge check: What is one of the most common reasons a pumper cannot establish a draft?
Complete the lesson, perform the drill, then mark the module complete.
7Standpipe, sprinkler/FDC & foam operationsSystem support requires more than ordinary attack-line mathNot complete
Lesson
Standpipe and sprinkler support should follow building preplans, system design information, department SOP and the specific fireground assignment. Elevation, system allowances, hose/nozzle demand and FDC supply configuration all matter.
Foam operations require matching concentrate, percentage, device flow range, inlet pressure and application method. Follow manufacturer instructions and local policy; flush equipment after use as required.
Know this cold
Standpipe: account for hose/nozzle, elevation and SOP/system allowance
FDC: secure a reliable water supply and correct connection
Sprinkler support: understand purpose and coordinate with command
Knowledge check: What should determine the pressure used for a real standpipe/FDC operation?
Complete the lesson, perform the drill, then mark the module complete.
8Troubleshooting & DO2 practical prepKeep water moving when conditions changeNot complete
Lesson
Troubleshooting begins by identifying whether the problem is on the supply side, pump itself, or discharge side. Use gauge trends, sound, vibration, engine load, valve position, tank level and crew reports to narrow the problem.
A strong practical candidate can calculate, operate and explain. Build a repeatable sequence for pump engagement, tank flow, hydrant transition, multi-line operations, standpipe/FDC, relay/draft and shutdown.
Know this cold
Low intake: investigate source, hose, valves and demand
Low discharge: verify throttle/governor, valve, line, nozzle and calculation
Overheating: maintain cooling/circulation per apparatus procedure
Cavitation: reduce demand and/or improve supply
Practice full evolutions under instructor-created changes
Knowledge check: The pump begins to cavitate while flowing several lines. What is the best immediate concept?
Complete the lesson, perform the drill, then mark the module complete.

Four-stage skills checkoff
These are original FireOps Calc training checkoffs, not official state JPR sheets. Adapt the scoring column to your AHJ.
Practical 1 — Inspection / setup
Run your full apparatus readiness sequence from memory. Use the local check sheet, identify defects, adjust the cab/mirrors, secure the apparatus, and verbalize safety-critical items.
Perform the central skill of this academy with no coaching. The evaluator should score safety, sequence, communication, control, and final operational result.
Repeat the evolution while the instructor changes one condition. The goal is to see whether you understand the system rather than merely memorizing steps.
NFPA 1002 driver/operator professional qualifications were consolidated into NFPA 1010. State and departmental certification systems can use their own editions, prerequisites and skill sheets. Verify before testing.
