Though there are services out there that will test the hose your rig carries and document it for you, if your department has the time, going through the hose testing process is a good way to review some pump operations with your engineers as well as have your crew learn what goes into maintaining your attack lines so they don't fail when you need them most.
Hose Handling II covers maneuvering a hoseline and developing the teamwork necessary to direct it. Not all of us are in the best shape, nor are all of us built like Rocky. When your backup man isn't working to compensate for the pressure at the nozzle, you'll know it, and you'll be spent sooner.
Not all of us are haz-mat technicians, but many of us are trained to the operations level, and most, if not all of us, have awareness training. What this means is that all of us may find ourselves at the scene of a haz-mat incident at any time and that we should be aware of what is happening, and why.
