The Power of Enhanced Stream Placement

2017-10-09T17:28:01-04:00

In our recent training at Ottawa Fire, Shawn Bloemker and I instructed firefighters on the value of enhanced stream placement. This is one of many concepts that Project Kill the Flashover advocates in our Tactical Thermal Imaging Program. The video above shows the stream being directed by the TIC at our training at Monroe Fire Department (video courtesy of a FLIR K65) In this short video below (video courtesy of Bullard LDX), one can see the moving convection heat currents over the firefighters head that are often missed due to zero visibility. This can be compared to being in [...]

The Danger of the Spot Temperature

2017-09-23T21:46:53-04:00

In traveling and teaching our curriculum, we continue to see a dangerous trend in TIC use. Many firefighters only read the numerical temperature reading in the lower right corner of the view finder otherwise known as the "spot temperature" or direct temperature measurement. This is a very dangerous issue. Here is why: The spot temperature is a numerical representation of the average of a certain amount of pixels within the focal point (or cross hairs) at a preset distance set by the manufacturer. This spot temperature is NOT an accurate representation of the overall environment. As you can see in the [...]

How Do Firefighters Measure Heat?

2017-09-20T23:03:15-04:00

How Do Firefighters Measure Heat? Today’s thermal environment of higher heat release fuels demands a diagnostic tool that allows firefighters to prevent thermal insult, identify and locate the fire’s severity, and locate any victims or firefighters in danger more quickly than ever before. And those who advocate that firefighters should wait to feel the heat to indicate their level of safety should read and remember the following: The equipment we use to protect ourselves or work in these superheated environments are designed to operate at only a Thermal Class III for a maximum of five minutes which equates to 500 degrees [...]

Ever read the instructions on your turnout gear?

Ever read the instructions on your turnout gear? The following quotes come directly from Fire & Emergency Manufacturers and Services Association (FEMSA) User Information Guide which comes with every brand-new set of Firefighter Protective Garments. The following information should be read and understood by all firefighters.  “If your protective ensemble is exposed to radiant, convective, or conductive heat, you may be burned underneath with no warning and no sign of damage to the protective ensemble. Be constantly alert to the possibility of exposure to radiant, convective, or conductive heat and other hazards” (FEMSA User Guide p. 2-4). “Burns are a [...]
