On June 7, 2022, the presenter headed out to assist in a live burn exercise. It was a day that changed his life. During the last burn of the day, he and his students were caught in a unilateral flow path. Due to inadequate water application and window failure, rooms in front of them flashed over and they found themselves in a 100 percent exhaust path. He was able to recognize the conditions and remove his students from the environment, but immediately returned quickly for a thermal imager and that’s when it went bad. He uttered the three words that makes everyone’s hair stand on end, “Mayday, Mayday, Mayday!!!” Having attended hundreds of hours of training and many conferences, he thought he knew what to do, but he was not ready for this. He gave a textbook LUNAR radio transmission and did not panic…until the pain started. He was not prepared for the extreme pain brought on by the severe heat. As he finally regained his composure, he heard the words no trapped firefighter wants to hear…the IC ordered the abortion of the rescue efforts due to the extreme conditions. Luckily, he was able to self-extricate and is alive to share his story in hopes of saving someone else.
