Fire & Rescue Service Tools

Lift, theoretical and dependable lift at your elevation, the intake pressure correction, net pump discharge pressure, and how much of your rated capacity you actually keep at that lift.

Friction loss, elevation, appliance loss, pump discharge pressure, solid-stream flow and nozzle reaction for up to five hose sections, with the supply-line hand methods alongside.

Wet-bulb globe temperature from your three thermometer readings, the ACGIH screening TLV and action limit for your work/rest cycle, and why the tables stop short of turnout gear.

Foam solution flow for an area, concentrate per minute and total concentrate for the run time, for Class A and Class B hydrocarbon and polar-solvent spills.

Quarter rule, climbing angle from where the butt actually sits, the height a given ladder reaches, the ladder you need for a given objective, and the collapse zone for the building.

ppm to mg/m³ and back at the temperature and pressure you are actually working at, ppm to percent by volume, percent LEL to ppm, and what an oxygen reading means.

Read your pitot gauge and your two hydrant gauges, and get the percentage method, the first-digit method, the available fire flow at 20 psi residual, and whether the test is even valid.

Needed fire flow by the National Fire Academy, Iowa State and ISO methods side by side, with exposure charges and a hoseline plan for the answer.

Rule of thirds, EOSTI activation pressure, the actual duration your cylinder will last at a real consumption rate, and how long your air has been going based on how much you have used.

How many gallons per minute a water tender shuttle can actually put on the fire — NFPA 1142 cycle time, the 10 % unusable capacity allowance, and how many tenders you need for the flow you want.
