Dear Bill,
Some time ago I was working as a field service Engineer for a company
that had a motor repair shop. We were also required to have an
emergency shut off for each bench. I think that a disconnect switch
within 6 feet of the bench was accepted. The problem with relying on
the service panel, is that they may not be readily accessible. If
there is a shock, or even if the unit catches fire, the power needs to
be removed as quickly as possible.
Good Luck,
Ray

The original question may not have been clear, but it dealt with whether or
not OHSA requires an emergency shut-off switch in an electronic equipment
repair shop. This is assuming that the repair technicians are trained
(qualified workers -- knowledgeable of the hazards of working on the
equipment) and wiring design in the shop was up to code and service panels
are identified. 29 CFR 1910 seems to not to specifically say that LOTO is a
requirement, for a technician who has a unit on a workbench and is
troubleshooting it and is exposed to high voltages. I thought someone might
have some direct experience with the question of emergency shutoff in the
event of an accidental electrical shock and the personnel remaining in
contact with the live voltage source.

OSHA regulations apply to the employer. It is the employer who must meet
standards such as the lockout/tagout standards. If an employer installs
listed equipment, it is likely that many of the kinds of hazards the
lockout/tagout standard was intended to prevent have already been dealt
with in the design. Where it has not been (for example, in servicing) it
is the obligation of the employer to provide for protection.
Note that for most types of electrical equipment used in the workpace,
use of listed equipment is required. OSHA regulations do not directly
deal with the sale of such equipment but its use in the workplace.
However, many state and local jurisdictions have laws requiring many types
of electrical equipment to be listed prior to sale to the public,
including the cities of Los Angeles and Chicago.
