MARCOR OSH PROGRAM MANUALCHAPTER 12LOCKOUT/TAGOUT ENERGY CONTROL PROGRAM12000. DISCUSSION1. The Lockout/Tagout Program ensures Marine Corps personnelare protected from injury during any servicing or maintenancedone on machinery or equipment, where the unexpectedenergization, start-up, or release of any type of energy (e.g.,electricity, steam, and hydraulic, pneumatic, gravity) couldoccur. The machinery or equipment will be rendered safe to workon by being locked or tagged out under requirements of 29 CFR1910.147, Control of Hazardous Energy (Lockout/Tagout); and 29CFR 1910.333, Selection and Use of Work Practices; and guidanceof ANSI Z244.1-2003, American National Standard for Control ofHazardous Energy, Lockout/Tagout and Alternative Methods.2. An energy-isolating device is considered capable of beinglocked out in one of two ways. It is capable of being lockedout if designed with a hasp, other attachment, or integral partto which, or through which, a lock can be affixed. Also, it iscapable of being locked out if it has a locking mechanism builtinto it. Other energy isolating devices are also consideredcapable of being locked out if lockout can be achieved withoutneed to dismantle, rebuild, or replace the energy-isolatingdevice or permanently alter its energy control capability.3. The Lockout/Tagout Program does not apply to the following:a. Work on cord and plug connected electric equipment whereexposure to hazards of the unexpected energization or start-upof equipment is controlled by unplugging the plug, which isunder exclusive control of the person performing the servicingor maintenance.b. Hot tap operations involving transmission anddistribution systems for substances such as gas, steam, water,or petroleum products when performed on pressurized pipelines,provided the following is demonstrated:12-3
