Case Study 5: Sour Water Pipeline Repairs

Incorrect.

This employer failed to meet the requirements of 29 CFR 1910.147(c)(4)(ii). The work authorization permit was overly vague in that the energy isolation points were not identified on the permit and the specific procedures outlined in their generic hazardous energy control procedure were not implemented. The employer may use a work authorization permit in conjunction with a generic hazardous energy control procedure if the permit identifies the equipment to be serviced, the types and unique energy characteristics to be encountered, specific energy isolation points, methods for safe work, and the process or procedures to be used to accomplish the task.
