from a hydrant or tanker.
6. Using a straight lay, set up water supply without a hydrant valve from a pressurized source
using LDH while initiating supply from a booster tank.
7. Using a reverse lay, set up water supply from a static source to a master stream device using a
single supply line while initiating supply from a booster tank.
8. Set up a relay involving at least three pumpers and using a static water source. The relay
should flow at least 500 GPM.
9. Have one engine connect to the steamer connection on the hydrant while second engine
connects to the 2-1/2-inch connections (a hydrant gate or ball valve may be used to avoid
shutting down the hydrant to allow the second pumper to connect)
B. All water will be discharged into a master stream device which is already set up or connected
directly to the pump.
C. These evolutions are designed to expose the student to various methods of supplying water at the
fire scene. The student should already be familiar with the techniques involved in each evolution.
What is being emphasized here is teamwork and operating efficiency.
ESTABLISHING SUPPLY LINES
* Supply line evolutions
* Supplying water from various sources
REMOTIVATION: Some of these evolutions can be performed by a single department while others may require assistance from neighboring departments. The drill provides an opportunity for interdepartmental drill that will benefit everyone. If the movement of water is not practiced on a regular basis, it will not be quick and efficient when needed. It is also an opportunity to develop or update procedures and practice some segments of the incident command system.
