This from Eric Haak on the 2-11 Alarm fire at 444. N. Lamon in Chicago
There were a total of 7 engines pumping at Saturday afternoon’s 2-11 church fire in Chicago. I thought I would send in images of each with the location they were working at.Engine 95 – B side on LamonEngine 117 – A side on FerdinandEngine 68 – On Lamon just north of FerdinandEngine 113 – Center of the 4800 block of HubbardEngine 44 – Center of the 4900 block of HubbardEngine 96 – Center of the 4800 block of FerdinandEngine 38 – Corner of Race and Lamon

Those are tremendous shots Eric and thanks for the information about the Engine companies that were pumping on the scene.

Peter, that’s been around forever. The reasoning is is that if you have too many rigs on the same hydrant grid at a fire, that the multiple pumps will pull more water than is available causing the soft suctions to collapse and the pumps to go into vacuum, impeding the pumping operations. It is standard CFD procedure that any company hooking to a hydrant on a 2-11or above MUST hook up with the hard suctions.

CFD companies carry hard suction that can be pressurized even at the low pressures as mentioned. The black hose has helix wire reinforcement. If suburban companies that carry the more modern and lightweight somewhat transparent hard suction that hose generally cannot be pressurize without the risk of rupture. Also, most suburban water systems are not of the low pressure high volume design that Chicago has.

Peter it is the most efficient way of getting water out of a hydrant.

Hydrants are low pressure high volume. If you’re using a lot of water you can run the risk of collapsing your hydrant line. With the hard sleeve you don’t run that risk.

I’m liking 44 and 113. Thanks for the eye candy.

Can somebody please explain why the CFD uses their hard suction hose as as supply line on multiple alarm fires? I’ve never seen that anywhere else.
