Training Scenario: Big Fire Hookup

This is a training scenario for how we get a large amount of water to your apparatus' pump - greater than 500 gpm.

Locally we call this a big fire hookup. I think in other localities you might refer to it as hooking up solid, or making big water.

I wanted to share this training scenario with you. Hope you enjoy it!

The biggest issue here is knowing your hydrants. If the hydrant is a red cap 0-499 gpm hydrant no matter how many lines you hook to it you won't get more than 499 pgm out of the hydrant.

I am a big fan of marking hydrants by color coding the hydrant caps. My current FD carries 2 - 2 1/2 inch hydrant gates in our hydrant bag and tap each hydrant with LDH and then put the gates on the remaining discharges.

I agree, thanks for pointing that out!

The recommendation for hydrant color coding is found in NFPA 291: Recommended Practices for Fire Flow Testing and Marking of Hydrants, you will find the color coding requirements in 5.2.1.2

A summary of hydrant classifications are:

Class AA - Light Blue - 1,500 GPM or greater

Class A - Green - 1,000 - 1,499 GPM

Class B - Orange - 500 - 999 GPM

Class C - Red - 499 GPM or less
