Where firefighters come to talk training

I recentlyposted about Heat Release Ratesand the rookie asking the question. Here is some resource material to help you with this. Heat Release Rates must be understood in the context that we may not be in the fire compartment or we may be at a presumed safe distance from the seat of the fire, but if the fire compartment is not cooled, the Heat Release Rate that is in today's fire environment can and will kill us in adjacent spaces.

How you cool is of course up for debate with information from new studies. The problem is this, we can't see energy from the HRR. So, to reduce temperatures that are exceeding 2000 degrees F, it is not wrong to cool from the exterior via a window CORRECTLY. There is a wrong way of doing this.

When stretching on the interior, which will have to happen whether we cool from the exterior or the first line makes the front door, cooling gases above our heads is critical along with expedient hose advancement, correct placement and the correct amount of unimpeded flow.

No matter what your thoughts are on the new studies, you MUST understand the fire behavior and know what it is doing, it is different in relation to speed and energy, and both can kill us withouth obvious signs of direct flame contact.

Keep in mind, I'm not a scientist, I am still learning, understanding and relating it to what we do.  Do the same and have understanding.
