Previously, we identified some NEC violations that electricians can (and should) repair for their own safety and that of their coworkers. Here are some fixes:
- Guard equipment [110.27(B)]. Look around your facility. Do you see dents or gashes from lift trucks on metal raceway, transformers, or other equipment? The damage probably violates the integrity of the equipment, but how much of it is ever replaced? Prevention solves this problem, which is why the NEC requires guarding. To protect equipment, install bollards that are capable of stopping a lift truck. You may need to install other protection, too.
- Post warning signs [110.27(C)] and enforce them. If you post “Authorized Personnel” signs, OSHA requires limited access to authorized personnel only—via a lock [1926.403(j)(2)]. OSHA does this because people are unclear on what “authorized” means. They make false assumptions, for example that they are “authorized” because their manager had a key that let them in the room previously to store paper on top of that 100kVA transformer.
- Lock doors on outdoor transformer pens [110.31(D)]. Not everyone in your work place understands the “don’t be there” rule about electrical equipment, and they may assume it’s safe to take a lunch break sitting next to that transformer. In the event of a fault, the consequences can be extremely serious. There’s also the issue of protecting the plant from closure by protecting children from gaining access to this equipment (of course, you also want to protect the children because that’s the right thing to do).
