The Occupational Safety and Health Administration (OSHA) regulation (29 CFR 1910.147) details safety requirements for the control of hazardous energy during the maintenance and servicing of machines and equipment. WHAT DOES THE RULE REQUIRE? In general terms, the rule requires that energy sources (pneumatic, electric, hydraulic, etc.) be shut off or disconnected while equipment is being serviced. Furthermore, the disconnected valve or switch must be locked to prevent reactivation while anyone is working on the equipment. In the case of air-operated equipment, a lockout valve must be used to cut...
