Know your rig
Have assigned positions
Don't crowd the nozzleman (You don't need to be breathing down his neck)
The easiest way to mitigate the incident, is to put the fire out. SO DO IT!
Know where all the crews are at. Don't spray water from the outside, especially if there are crews inside (STEAM STEAM STEAM)
Don't bust every window in the house (Think Vent)
Get a primary search done as you go, but remember if the fire goes out, so does most of your rescue problem
The day you quit training, is the day you retire!
