Oregon Occupational Safety and Health Division - (1) Preparation for shutdown. Before an authorized or affected employee turns off a machine or equipment, the authorized employee shall have knowledge of the type and magnitude of the energy, the hazards of the energy to be controlled, and the method or means to control the energy. - (2) Machine or equipment shutdown. The machine or equipment shall be turned off or shut down using the procedures established for the machine or equipment. An orderly shutdown must be utilized to avoid any additional or increased hazard(s) to employees as a result of the equipment stoppage. - (3) Machine or equipment isolation. All energy isolating devices that are needed to control the energy to the machine or equipment shall be physically located and operated in such a manner as to isolate the machine or equipment from the energy source(s). - (4) Lockout or tagout device application. - (i) Lockout or tagout devices shall be affixed to each energy isolating device by authorized employees. - (ii) Lockout devices, where used, shall be affixed in a manner to that will hold the energy isolating devices in a 'safe' or 'off' position. - (iii) Tagout devices, where used, shall be affixed in such a manner as will clearly indicate that the operation or movement of energy isolating devices from the 'safe' or 'off' position is prohibited. - (A) Where tagout devices are used with energy isolating devices designed with the capability of being locked, the tag attachment shall be fastened at the same point at which the lock would have been attached. - (B) Where a tag cannot be affixed directly to the energy isolating device, the tag shall be located as close as safely possible to the device, in a position that will be immediately obvious to anyone attempting to operate the device. - (5) Stored energy. - (i) Following the application of lockout or tagout devices to energy isolating devices, all potentially hazardous stored or residual energy shall …
