I can remember, as a young firefighter, feeling rather proud of the fact that I had developed a certain prowess for driving one of our old, stick-shift engines. Even though it had to be double-clutched and required finesse to get it into third gear, I felt I had mastered it.

One night, as I was advising another firefighter about how to do it “right,” one of the older firefighters spoke up and bet me that he could drive the truck out of the bay, circle the station and back it into the bay without ever touching the clutch. Of course, in my opinion, that was impossible.

Never mind the double-clutching issue; he was going to have to transition from drive to reverse and that would surely require a clutch. I took the bet. I watched him release the brake and start the vehicle in gear. It took two starts (the first one to get it rolling), but he managed to not use the clutch. He drove around the station, shifting gears without the clutch, to my utter amazement.

Learning a Lesson

We approached the front of the station, where the veteran firefighter would have to change from drive to reverse, and I knew I had him. As he circled in front of the bay and pointed the truck away from the station, he slipped it out of gear and let the engine roll across the street in front of our station.

As we approached the curb on the far side of the street, he ever so gently feathered the brakes so the engine’s front wheels struck the curb just hard enough to stop the forward momentum of the vehicle – and rebound it backwards. At this point, he simply slipped the stick into reverse and backed it into the station.

I washed his car every shift for a month, but learned a valuable lesson: no matter how much you know; there is always more to know.

I can remember one of the first thermal imaging classes I taught. It was at an average-size, combination department that had recently purchased its first three thermal imagers. As the firefighters began to file in, I could not help but notice a less-than-enthusiastic demeanor. Eventually, they all found places to sit and we got underway. For the first 15 minutes, the group was respectful, but clearly not engaged. In the next 30 minutes or so, the group periodically engaged, but by the end of the first hour, they were all enthusiastically engaged as they thought about new uses for their thermal imagers.

As this was my first class, I was being mentored/monitored by a senior instructor. After the class, during his critique, I brought up what had happened. His response was, “Oh, it’s always like that. These guys are trying to figure out how you are going to take four hours to explain what they understood in 10 minutes – that a thermal imager can see through smoke. Eventually, they figure out that you are here to talk about all of the other things it can do, and many of them have never really thought about it before.”

Since then, I have taught hundreds of fire departments and thousands of firefighters on four continents and more than 15 countries and guess what? Every class is the same. Every single time, firefighters stream into the room with the same forlorn look on their faces and I know what they are thinking. Every single time, they leave the training with minds reeling about all of the new applications. The scenario repeats itself over and over again.

Too Easy?

The problem is thermal imaging is extremely intuitive. Turn it on, see through smoke. That’s about as complicated as it gets. The average fire department receives a thermal imager and it takes the members about five seconds to figure out how to insert the battery and locate the power button. Five more seconds for the imager to power up and a perfectly discernible grayscale image appears. No more difficult than a flashlight to operate. Even a caveman can do it, as the Geico ads say.

Training can, and many times does, stop there. You really don’t need any more guidance. If you got that far, you pretty much have it figured out – if all you want or expect to do with your thermal imager is see through smoke.
