Mike :
I believe the 25 psi business is some OSHA-related requirement (same as the
one for air guns). Just keep the various parts of your body away from the
drain opening, and you should be just fine bleeding 175 psi.
The auto-drain is not especially efficient (although much better than
nothing), so it may leave a fair amount of water in the tank at any one
time. Since water accelerates the internal corrosion that can eventually
kill tanks, it's better to be sure it's dry when leaving it for any length
of time. I've got my drain valve rigged with a ball valve, and a lever
positioned such that I can operate it with my foot. It only takes a second
to open the valve, wait until there's no appreciable amount of water coming
out, and close the valve. The pipe before the valve also acts as a catch
basin, so if there's a few cc of water left in the tank, it will corrode a
replaceable length of pipe.
An unpressurized tank is always safer than a pressurized one, yet IMO the
danger is not enough to worry about unless you routinely sleep next to it.
If the danger of a tank explosion worries you, build a box for it, or better
yet, a box outside !
I'll take your airless compressor, if you live near LA ...
