This is a hard pushing fire and getting water on it fast is important.
But, be careful of where and how you place your apparatus.
The operator is very likely having a difficult time at the pump panel even if he is in a mask and tank.
In addition, if that fire would flash, that truck is now an exposure. If your department is like mine, it can’t afford to have a truck out of service for long waiting for a replacement. Not to mention the insurance probably wont buy a new one at what they cost these days.
Just take some time to think about where you are placing your apparatus. If your apparatus becomes disabled because of poor placement while you are inside, things could get bad real quick.
Be aware and stay safe.
