6. 0 Lockout/Tagout Procedures n n 1/24/2022 6. 3 Equipment shutdown -- if the equipment or machine is operating, shut it down by the normal stopping procedure (depress stop button, open switch, close valve, etc. ). 6. 4 Isolate energy source -- de-activate the energy isolating device(s) so that the equipment or machine is isolated from the energy source(s), and apply appropriate lockout/tagout device. 12

6. 0 Lockout/Tagout Procedures 6. 5 Application of lockout/tagout device -- a lockout or tagout device shall be affixed to each energy isolating device by the authorized employee(s). § § 1/24/2022 a. The lockout device shall be affixed in such a manner as to hold the energy isolating device in a “safe” or “off” position. b. The tagout device (permit tag) shall be affixed in such a manner as to clearly indicate that the operation of the machine or equipment is strictly prohibited. c. When the tagout device cannot be directly affixed to the energy isolating device, the permit tag shall be located as close as is safely possible to the device, in a position that will be immediately obvious to anyone attempting to operate the device. d. When servicing and/or maintenance involves employees from different departments or involves SMU personnel working with outside contractors, the lockout/tagout shall be performed in accordance with the guidelines identified in Section 8. 0, Group lockout/tagout procedures. 13

6. 0 Lockout/Tagout Procedures 6. 6 Release of stored/residual energy -- stored or residual energy shall be dissipated or restrained by methods such as grounding, repositioning, blocking, bleeding down, etc. n a. Potential sources of stored or residual energy can include capacitors, springs, elevated machine members, rotating flywheels, hydraulic systems, and air, gas, water or steam pressure, etc. . n b.
