This is fairly good sized single-family home. Fire has vented at the ridge, at least appears as such.
We have not confirmed that everyone is out in this late night fire.
There is a basement and most of the bedrooms are on the upper floors. Those are not fake dormers.
How do you procede and what are your main concerns and why?
What is your size up and as the first officer, what is your first action?
Get your company together and hammer this one out.
Stay safe and train hard.
