Rescue and search because the BC's don't believe in anything but PPV!
First up, no subsequent arriving apparatus should be making an IAP. First in should have established IC. and a strategy. Then the IAP. Having said that and efforts should be on rescue. Information is good that we have a trapped victim on the second floor. All resources should be used for the rescue. PPV is a must to clear heat and smoke which will aid in search efforts, also it will reintroduce fresh air which is vital for victim survival. Vertical ventilation is too time consuming at this point. The fire is already blowing out a window, and smoke is exiting as well, "everything looks ideal for ppv". Two preconnect lines should be used, one to defend the exit for the crews on the second floor. The second to advance on the second floor . The attack line should not engage with the fire fight unless necessary to assist with second floor search. Man power on the second floor will co-ordinate the search until the person is found. Once rescue is accomplished the IC will retool the IAP and then go after the fire.
