"Yes I am one of those safety first guys also a engineer by training and
spent a lot of time in the aviation industry where there are no second
chances to do it right "
There is a big difference between operating a high voltage supply without
any covers on it and operating a supply with a cover and lots of screws,
especially when it has danger high voltage signs on it.
Comparing it to the aviation industry, I regularly start the engine of my
friend's aircraft by propping it. The prop does not have any safety screen
around it. I could trip and cut my head off. I could sneeze at the wrong
time and lose an arm. I am much more concerned about that than the
possibility of removing a dozen screws while I am sleeping and not grounding
out the caps before working on the set.
As to opening up the set during a 2 day contest and forgetting all sense of
self-protection, it is no more likely than going out to cut wood with my
chain saw after a drinking binge.
When I was a kid, I used to ride around in a car without a child restraint
and without air bags. I drank from garden hoses made with lead, no doubt
played with toys made with lead and dove from bridges. I climbed towers
that did not have protective devices and even ate eggs and hamburger that
were not cooked.
The thing is, that a safe person will assume that the protective devices
have all failed - so take the proper precautions whether or not the devices
are installed or removed.
I leave the protective devices in place, but I do not blame anyone for
removing them and I certainly do not want to lecture him that my ideas on
safety trump his.
