PUMPING TO EXTENDED LAYS
THE Rapid Attack Pack (RAP)
Our Rapid Attack Packs are essentially a "courtyard lay" where access to the fire compartment is our primary concern.
Each RAP comprises 100' of 1 3/4" hose and a gated wye. The Nozzleman deploys those packs to the point of entry while the three-man (plug man) pulls a 3" supply hose to that point of entry as well. The RAP is connected via the gated wye, allowing the use of two attack lines from a single supply hose.
Two main issues NEED to be addressed and managed when pumping to a RAP. The Roll Steady recently posted a video as part of our Pump Series on YouTube that outlines what to pump to a RAP and addresses these main issues:
THE SUPER BOOSTER
The Super Booster is an extended lay attack line firefighters used in Dallas in the 70s and 80s. Recently, we’ve seen a few engine companies begin to utilize this “old” tactic, and felt it was worth discussing in this lesson.
Super Boosters are comprised of a 2 1/2" feeder line that reduces to a 1 3/4" attack line. The goal here is twofold:
1) utilize the reduced friction loss in the 2 1/2” hose when extended lays are necessary.
2) it is technically possible to reach flows of 200-225 GPM from our TFT nozzles. Keep in mind, though, that this will result in massive nozzle reaction.
Extended Lays Utilizing The Blitz Fire (or Portable Monitor)
In Dallas, we utilize the TFT BlitzFire and Elkhart RAM XD. This is preconnected to a 3" supply line on the rear of our engines. The line is pulled to the location needed and then cut and connected to a discharge on the engine:
