I remember back when I used to work as a HVAC specialist I had some pretty dangerous jobs a few times; Working a lot in commercial HVAC repair it was a bit different than your average HVAC worker, but one time I had a particularly close call while toiling in a church trying to repair their commercial heating as well as air conditioner.
I was way up on a scaffold because it was a cathedral category church, as well as the air vents were all the way up there.
After the repair of the commercial HVAC program I had to make some new adjustments to the air vents which were not directed properly in the church. Well, to make a long story short the scaffold had a little issue as well as it came particularly close to me falling almost 50 feet to our death to the hard cement flooring of the church! Lucky for me I had a safety restraint on, so when it all went wrong I was protected by that as well as was able to sort of scale our way down the wall back to the ground safely. But that was an severely close call! And this was also what ended up leading to me leaving the HVAC corporation I was toiling for. I ended up going to work for a HVAC supplier that only dealt in residential HVAC upgrade as well as repair. With that it was safe as well as there would never be any dangers.
