I go in a get them out....easy.
Charged 38mm I don't want any ventilation to occur yet until i can eye ball what is going on. Venting high before a crew has eye balled the main fire could extend it or create other nastiness.
The key here is go in fast, protect yourself with good compartment techniques control your exit and make each room safe as you penetrate. Fire First though - if I come across fire I will knock it down. No point doing a rapid search without fighting fire. Putting the fire out makes the environment more survivable.
Grab the crew and drag them out -
Once the 1st crew is out I'll go back in and knock it down then get the place vented, high first then PPV in the front door.
That's straight out of my imagination - as all hypotheticals are.....
