RE: OSHPD Requirements for Surgical Lights

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Thanks. Of course, we have similar provisions in Canadian code for essential
facilities. However, I am curious why the OR lights have been described to
have service connection/support characteristics that would typically exceed
the essential service requirements.

Is there something special about these lights and the service support
requirements or is it simply an issue that by the time you accomplish an
adequate support design due to other considerations, the design will exceed
any rational (or irrational) expectations and code requirements?
