OSHA and ASME compliant belt guard question

[ET50]

I understand the requirements for a belt guard required for 2 sprockets and a synchronous belt per OSHA and ASME standards. The belt in question is part of skid mounted mechanical apparatus. If this skid has an enclosure (4 sides with doors and a roof) does it still require an OSHA and ASME designed belt guard? I say yes because unless you have a fail safe way to shut the machine down so there is no danger it must meet those regulations. I was told that because it has an enclosure surrounding the machine it doesn't need to meet the regulations. Anybody have experience with this type of situation?

It's not suppose to be a rocket science to realize that a person in the vicinity of a rotating shaft and coupling unprotected locally by a guard can be harmed. The workshop or a shed wall is not replacement for a close guard of that coupling...I bet the one who told you there is no need for a belt guard is the one keeping the cash.

We all agree that if the enclosure doors are opened for a person to do whatever is required with that unit, sure the unguarded rotating elements and belt are potential hazards.
