Abstract:

An employee received an electrical injury after coming in contact with an energized electrical circuit while wiring a relocated emergency generator; the employee subsequently died of the injury. The subsequent investigation revealed three central themes involved in the mishap:

1. Implementation and Verification of Lockout / Tagout Procedures (the subject of this lesson),

2. Accurate Drawings of Facility Systems as a Prerequisite to Project Implementation, and

3. Demand and Ensure High-Quality Safety Performance from all Contractors.

Each theme is published as a separate lesson. (A fourth lesson underscores the successful implementation of the preliminary investigation, which was critical to performing a successful, formal mishap investigation.)
