Looking for some help from the Pros, here.
In a relay pumping operation where you have a supply pump, such as a portable feeding a pumper, which then feeds an attack truck, what is the proper start-up shutdown procedure?
Its clear that you start by feeding from the portable source to the relay pumper, then that truck advises the attack unit that water is available, and when the attack operator advises he/she is ready the relay charges the supply line and the attact truck then starts fire fighting operations.
The question is what is the proper way to coordinate a shutdown procedure? My assumption is that the attack truck advises the relay pumper that water is no longer needed and shuts down, next the relay pumper acknowledges and shuts down, and finally advises the portable that they can shut down. I have also heard that that the portable should shutdown first after it knows that the attack truck no longer needs water. But that seems to be counter-intuitive to me.
What's the general consesus? (or better yet the absolute proper procedure)
Thanks!
