APPENDIX E Lockout/Tagout Requirements & Procedures 1.0 DEFINITIONS Lockout — Involves using a device such as a padlock, blank pipe flange, chain key block, etc. to isolate energy from employee exposure. Tagout — Involves applying a tag to the energy isolating device with written information concerning the date and name of person who applied the lock and tag. 2.0 LOCKOUT/TAGOUT POLICY This procedure establishes the minimum requirements for lockout/tagout of electrical energy sources, mechanical, hydraulic, pneumatic, thermal or chemical process energy. It is to be used to ensure that conductors and circuit parts are disconnected from sources of electrical energy, locked (tagged), and tested before work begins where employees or subcontractor could be exposed to dangerous conditions. Sources of stored energy, such as capacitors or springs, shall be relieved of their energy, and a mechanism shall be engaged to prevent the re-accumulation of energy. Lockout/tagout procedures shall be used prior to performing tie-in operations, maintenance, repair or adjustment of any device where exposure to hazardous energy sources may occur. 3.0 RESPONSIBILITY All effected employees and subcontractors shall be instructed in the safety significance of the lockout/tagout procedure. All new or transferred employees and all other persons whose work operations are or might be in the area shall be instructed in the purpose and use of this procedure. The ATC Project Manager shall ensure that appropriate personnel receive instructions on their roles and responsibilities. All persons installing a lockout/tagout device shall sign their names and the date on the tag and on the Lockout/Tagout Isolation Record (see Appendix E.1). 4.0 PREPARATION FOR LOCKOUT/TAGOUT I. Review current diagrammatic drawings (or other equally effective means), tags, labels, and signs to identify and locate all disconnecting means to determine that the source of energy is interrupted by a physical break and not deenergized by a circuit interlock. Make a list of disconnecting means to be locked/tagged. 2. Review other work activities to identify where and how other personnel might be exposed to sources of energy. Establish energy control methods for control of other hazardous energy sources in the area. Provide an adequately rated voltage detector to test each electrical phase conductor or circuit part to verify that they are deenergized. Test the voltage detector to make sure that it is working properly. 5.0 LOCKOUT PROCEDURE Complete the Lockout/Tagout Isolation Record (see Appendix E.1). All affected employees in the area shall be notified that a lockout is being performed. The equipment being locked out shall be shut down using normal shutdown procedures. (i.e. operator's control station, stop button, etc.). Any residual energy shall be identified and dissipated at this time. All equipment energy sources shall be neutralized. (i.e. electrical disconnects shall be opened, valves closed, blanks inserted in piping, springs returned to neutral position, other energy sources as required)
