OSHA Lock-Out and Tag-Out Requirements
OSHA Standard 29 CFR 1910-147 Control of Hazardous Energy Sources (Lock-Out/Tag-Out)

unexpectedly while servicing equipment. The rule requires:
(1) Turning off equipment power and fuel under pressure.
(2) Use of a locking device (breaker, valve, etc.) or label device with a warning tag.
Station employees and service contractors need to understand and comply with this program
completely to ensure safety while the equipment is down.
