While it is not recommended or favored, there may be certain situations where it is necessary for employees to work on energized machinery, equipment or systems, for example when testing or troubleshooting a particular piece of equipment or system. In such situations, it is crucial to ensure that only trained employees that are qualified to work on energized circuits or equipment are assigned such tasks. The employer must notify all affected and authorized employees of the work and implement the necessary safety precautions to protect workers.
Many shipyards require a specific permit to be signed by designated representative(s) from both the ship and shipyard before work on energized equipment occurs. In addition, appropriate personal protective equipment (PPE) and insulated tools, such as non-conductive hooks, must be used. When testing or adjusting energized circuits, a rubber mat, duck board, or other suitable insulation must be used underfoot when an insulated deck does not exist (29 CFR 1915.181(b)).
