The crew & I were at a commercial work site. Not just any site, either, all of us were on the roof of the modern shopping mall, installing the HVAC duct. It was a hot morning out, & at this point all of us had been laboring our butts off for over 10 straight minutes with no breaks. It was the greatest single task all of us had ever untaken, & everyone was focused on doing it right. If all of us nailed this task, it would lead to other big-money contracts down the line! With all the pressure & stress, I lost focus & had a little accident when a piece of HVAC duct broke away & fell on my leg. This wasn’t just any piece of HVAC duct, it was eight feet wide & twenty feet long, being hoisted by a crane. When it landed, it was multiple hundred pounds worth of sheet metal HVAC duct crunching the bones in my leg from the knee down. I was lucky the docs were able to save the leg at all! As it stands, I will be in a wheelchair for multiple weeks, so I can no longer serve as an on-site Heating & A/C tech. Instead my bosses moved me into the front office of the Heating & A/C company, where I now work with the administrative assistants. I am surprised at how much there is to suppose about the Heating & A/C industry that I had never experienced. I’m not saying I loved it, but it was a studying experience, & if I ever become an Heating & A/C supplier running my own shop, this experience will be infancy.
