The smooth bore tip has been around for several decades with little if any changes, thus limiting its use. This class takes another look at smooth bores with a whole new outlook to show that this great firefighting tool can even be better. No more standard nozzles, pressures, and flows. Students will see that both higher and lower nozzle pressures through smooth bores deliver water at higher flows and in harder-hitting and farther-reaching streams. They will learn how to create a 500 gallons-per-minute (gpm) handline with a 1½-inch tip, a 300-gpm super stream with a 1-inch tip at 100 pounds per square inch (psi) nozzle pressure (NP), and a high-pressure smooth bore tip deck gun operating with a 1-3/8-inch tip at 175 psi NP, to name a few. All operations discussed are within the guidelines of the manufacturers of all equipment used.
Students will learn the following:
- Establish a base line for the current rules governing smooth bore tips for handlines and master streams.
- Demonstrate the flow capabilities of handline using smooth bore tips with different nozzle pressures and flows that are not in line with the current standards.
- Demonstrate different blitz attack evolutions using high flow handlines.
- Demonstrate nozzle handling techniques for high flow handlines.
- Demonstrate high pressure smooth bore tip operations for master streams.
