Practice
Roll a randomized problem, then solve it on the live panel: engage the pump, open your lines, and throttle until every line gauge holds in its band. Each problem ends with the worked math, the why, and the common mistakes.
First Attack Line
BeginnerRoom-and-contents fire, single story. The officer calls for the crosslay to the front door.
Not tried yetStart drillThe Big Line
BeginnerProHeavy fire showing — the officer wants the two-and-a-half for reach and volume.
Uphill Stretch
IntermediateProThe fire building sits up a grade from the engine — the line climbs the whole way.
Know Your Nozzle
IntermediateProSame crosslay, but which nozzle is on it tonight? Check the tip before you set the pump.
Through the Wye
IntermediateProLong courtyard stretch — the attack line works off a gated wye at the end of the lay.
Two Lines, One Pump
AdvancedProSecond crew stretches a backup line. One pump pressure has to serve both — gate the line that needs less.
Know Your Automatic
IntermediateProAutomatic nozzle on the crosslay tonight. It makes a good-looking stream almost no matter what — so the pump panel, not your eyes, has to tell you the line is fed.
Stretched Short
AdvancedProFirst-due line to the front door. Get water moving — but this fire isn't going to sit still, and the crew may have to reach deeper.
Weak Hydrant
AdvancedProThe only hydrant on this block is a tired one, and the officer wants the big line. Open the intake, feed the line — and don't pull the hydrant down past where it can recover.
Watch Your Water
IntermediateProNo hydrant yet — you're on tank water alone. Get the line working, then know exactly how long that water lasts before someone has to feed you.
