I'm looking for some advice here brothers/sisters. I am a newly promoted lieutenant on a quint in central texas. We staff all four of our companies with a minimum of four personnel. Our SOGs say that the decision to operate as an engine or truck company is up to the officer on the first in quint. We train/operate very similar to the truck operations in the northeast. Officer and FF take the TIC, water can and irons and go interior to locate the fire, attempt to knock down/darken the fire then search away from the fire. The engineer and OVM/Roof guy kills utilities, set up the aerial ladder, throw ground ladders and prepare for vertical ventilation. There are a few situations where we automatically pull a line: vehicle/dumpster/defensive fires. We are also supposed to pull a line for an exterior fire such as a shed attached to a house. We recently had a fire in a two story residence with fire venting from the window of a bedroom on the second floor. This was at 9pm, three vehicles in the driveway and front door was locked. This night I had five assigned to our quint so three of us went interior and located the fire then attempted a search. The fire was too intense for the water can to do anything so we backed up to the top of the staircase and were met by the first in engine with a line. My question is what would you have done in my shoes? Would you have pulled a line or performed as a truck?
