Re: Panelboard Access

That inconvenience is what makes it a hazard! If you had accidentally come into contact with something live within the panelboard (and thank heavens that you did not), and if the shock was beyond the ?let go? value of current, then perhaps the only thing that could have saved your life was having the weight of your falling body pull your hands away from the panel. But if you did not have enough room to fall, if for example you had been propped up against the work bench, then you chance of surviving the event would have been dramatically reduced.
I have said this before on this Forum, and I?ll say it again: The reason for having working clearance is not to give the worker room to work. It is to give the worker?s body room to fall.
When you consider taking risks, there are three things that must be taken into account.

- <font size="2" face="Verdana, Helvetica, sans-serif">The first consideration is the probability of an accident. If you are skilled, and if you are careful, and if you are not under any special kind of pressure, then the probability of an accident may be low.</font>
<font size="2" face="Verdana, Helvetica, sans-serif">Looking only at this probability, you might think the risk is worth taking.
</font>
- <font size="2" face="Verdana, Helvetica, sans-serif">The second consideration is the possible consequences of an accident.</font>
<font size="2" face="Verdana, Helvetica, sans-serif">You must absolutely believe that an accident can happen. The question to ask is, ?How bad can it be?? We have all been shocked at some point in our careers. That was bad enough. But it can be worse. We lose far too many members of our profession every year to electrocution.

- <font size="2" face="Verdana, Helvetica, sans-serif">The third consideration is what can you do to reduce either the probability or the consequences of an accident.</font>
<font size="2" face="Verdana, Helvetica, sans-serif">In this specific example, providing the proper working clearances can contribute both to reducing the probability of an accidental and to reducing the consequences of an accident.
