Well Neal if you are in charge of industrial safety then you have done a freaking lousy job of getting this information to the workers. It's your job to make it known. Stop passing the blame onto OSHA and do what you are supposed to do.
I am not in charge of industrial safety. I work in that field. It is not my responsibility to inform workers of all OSHA rules that pertain to their environment, only for those applications and products I am involved with. I didn't 'blame' OSHA for anything. OSHA is in some way a reactionary body, adding or changing rules and regulations as or when accidents happen, in an attempt to keep them from occurring again- which is not a bad thing. It becomes overkill when a once-simple task now requires special PPE, placarding/signage, area barricading, lockout/tagout procedures, etc. because someone hurt themselves.. I was merely pointing out how overwrought with protective measures and safeguards our society has become, and I mentioned the industrial safety world because the same over-protective mindset applies to the OP's inquiry about installing a service pit- at least where I live (and from the sounds of it, other members' locales), it is not allowed, at least for residential use, period. Sadly, I think a lot of it likely boils down to liability. We live in a time when no one wants to accept personal responsibility for anything, and as I mentioned, a lot of people need coddled through life, or seem to anyway. Modern cars are another example- lane keep assist, adaptive cruise control, rear view backup cameras and the like are all there because some people don't pay enough attention when they drive, so they were implemented as safety features (all of which have pending legislation making them required features over the next several years). The more safeguards we put on ourselves, the less we actually have to think and pay attention to what we are doing. The natural selection comment was to this point. Accidents/mistakes, while I do not want them to happen, is what causes us to learn. Put reasonable safeguards in place, make things easier and safer to do or operate, but don't eliminate options outright just because someone who is not familiar with or wanting a pit is scared to let someone else have one.
Sadly, several here seem to have missed the tongue-in-cheek comment I was originally trying to make- that one day, the 'Cowboy after OSHA' cartoon is where we will be- for real.
I apologize to the OP for all of the hijacks to this thread- I have tried to keep it on-topic and related to it, even if indirectly.
Neal.
