I want to do a training session on handelling large attack lines. WE don't do it often but it's something we all have to be familiar with. Can you direct me to info on the net or you can list some of your own tips. thanks..

Years ago on an old dept. I had a LT. during drill one time, pull a 2 1/2 and put one firefighter on the nozzle (TFT straight stream). He had the engineer throttle up the pump while the FF did evolutions on the hose until the FF couldn't handle it anymore. After noting what the pressure was, he added another guy on the hose and increased pressure until they both couldn't control it. And so on until he had half a dozen guys on the line. Just to show what they could expect at the scene on a 2 1/2 pumping at pressure.

A good mulit-company drill (we have three members on a rig) is to charge the line to operating pressure, place five on the line about six feet apart and enter a building. The last person on the line stays at the first corner you come to, next corner the last person again. Keep going into the structure dropping the last person at the corners. You will be suprised how easy it is to advance the line. We also use 1 1/4" smooth bore and figure 20psi fricton loss per 100'Comment
