Case Study 3: Replacement of Nitrogen Pressure Vessel Seals

Correct.

The employer is required to implement a procedure which affords each person working on this pressure vessel a level of protection equivalent to that provided by the implementation of a personnel lockout or tagout device. Under these circumstances, each employee must affix a personal lock or tag either on each energy isolation device or on the group lockout device, group lockbox, or comparable mechanism, and each employee must be permitted to verify that all energy sources are effectively isolated.

For more information: Refer to the Lockout/Tagout standard part 1910.147(f)(3), STD 1-7.3, paragraph H.8 (a through h) (Note: You must scroll to paragraph H.8.), and the detailed discussion and acceptable examples in Appendix C, paragraph B (Note: You must scroll to paragraph Appendix C, paragraph B.).
