Case Study 3: Replacement of Nitrogen Pressure Vessel Seals Incorrect. The group lockout or tagout provisions would apply here. 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 be permitted to verify that all energy sources are isolated and to affix a personal lock or tag either on each energy isolation device or on the group lockout device, group lockbox, or comparable mechanism. For more information: Refer to the Lockout/Tagout standard part 1910.147(f)(3), and The Control of Hazardous Energy – Enforcement Policy and Inspection Procedures. |
