This is an incident that could turn out to be very interesting.
This is going to address the use of back up lines and when they are deployed.
I had an interesting conversation about assignments, as you could tell from the previous post.
This discussion circled around the deployment of the second apparatus on the scene. This is not a metro response where engines do engine work and so on. Rather, this is where the second in unit is assigned upon arrival.
With this picture in mind, what does your second in unit do? Does it backup the first in crew with a hand line? Does it perform ventilation? Just where do you order this second in crew and what are the tactical priorities?
I believe that there is a time and situation for using the second in unit for a back up line, but not automatically just because they are the second unit there.
What do you think and why? You gave some great insight into run procedures, so I know there will be some great conversation on this one.
Stay low and be safe.
