Part 15 Managing the Control of Hazardous Energy

Highlights

  • This Part reflects the most current views on “locking out”, widely referred to as the “control of hazardous energy”.
     
  • This Part explicitly recognizes that the control of hazardous energy applies to machinery, equipment and powered mobile equipment, as well as piping, pipelines and process systems containing a harmful substance under pressure.
     
  • This Part recognizes that energy-isolating devices can be secured

    (a) by individual workers,
    (b) by a group (often referred to as a “group lock-out”), or
    (c) a complex group process (a procedure-based “group lock-out” process that is implemented when circumstances, such as a plant turnaround, make “group lock-out” impractical)

  • Sections 215.4 and 215.5 present requirements specific to pigging and the isolation of piping.
