How many Firefighters required to flow a 2.5″ Attack Line? How much does a 50 section of 2.5″ weigh when charged? How much can you flow through your 2.5″? Do you leave the 1″ tip on? Does your FD deploy 2.5″ on commerical building fires? WHY NOT? Does your FD use 2.5″ on fully involved garage fires? Why is this method above more effective than the coil?

Depends on who and how they were trained as far as how many to handle 2 1/2. I don’t select 2 1/2 based on structure type I base it on volume of fire and occupancy type.
Yes, the 2.5″ is a great tool. You have to understand its abilities and limitations to deploy it apropriately. The 1′ tip gives you 210 g.p.m., the 1 1/8″ tip flows 265 and the 1 1/4″ tip flows 325 g.p.m. @ 50 p.s.i. Remember, more water= more nozzle reaction. On a rockin’ attached garage, you bet I’m pulling the 2 1/2″ Blitz Line and using the 1 1/4″ tip. The pic above demonstrates proper hose line use. A crew cannot flow 325 g.p.m. and move the line around. Pin it down on the driveway and darken down the fire, then you can take care of business by attaching a 1 3/4″ to the nozzle.
