Although standing in a fire is very dangerous, these students are doing it for a brief moment as an exercise to feel the temperature difference between hot standing height and the cooler floor. The volunteer fire service is one of those things that once it has worked its way into your blood it sort of stays there. You might not continue as an active firefighter but there is always a sentiment that lingers for those who still involve themselves. It is not easy to spring out of bed ready for action or leave in the middle of dinner, indulging oneself in a hobby, or other such activities.
Instructors kindle a fire for the next team of firefighters.
Note the beginning of a well defined layer of smoke and hot gasses. These photographs were taken during a training session with a couple different fire departments in the Beaver County, Pennsylvania. This was a house, and a rather nice one, that was schedule for demolition due to the expansion of an industrial park. Fires were lit in various rooms and teams took turns locating and extinguishing the fires. This continued for most of the weekend.
