At where I work full time on residential fires we run 4 engines 1 truck 1 medic, and FU 10 which has our Battalion Chief and his driver the Assistant Battalion Chief. But all our engines run with 3 people in them the truck runs with 4.
1st due engine, pumps and runs the attack line. LT and FF. goes in
2nd due engine, grabs the hydrant then takes the 5" to the 1st due engine, after that is hooked up then we run 5" off the other suction of the 1st due engine to the suction of the Truck. After that is complete then they head to FU 10 and get the clip board with the roster and get out the rit basket and the 2 saws and take them up to the house start the saws to make sure they are running and do a couple of walk a rounds to find out where stuff is stairs for the upstairs, basement, bathrooms, kitchens, we try to call out anything that might be good to know. The clip board keeps track of who is in and who is out.
3rd due engine, takes the back up line in, the LT. and the person riding backwards, will go in and the driver will shove hose for both attack and backup line.
4th due engine will hook up a 2nd hydrant but not drop its 5" unless it is asked for by FU 10. After that is complete then they go to FU 10 and find out what is needed to be done.
The truck, driver’s side does all outside operations, 2nd means of egress, laddering the 2nd story windows, horizontal or vertical ventilation, PPV after the fire. utilities. LT's side of the truck does the interior search.
Medic will go to find out what is needed to be done and take care of it.
