What should be done to ensure safety while working on electrical panels?

Locking and tagging the electrical panel is a critical safety procedure designed to prevent accidental energization while work is being performed. This method ensures that the panel cannot be turned on by unauthorized personnel, significantly reducing the risk of electrical shock or injury. The lockout/tagout (LOTO) process is critical in multi-person environments where multiple workers might be involved, ensuring everyone is aware that maintenance is taking place.

In addition to securing the panel, it is also a good practice to notify all nearby personnel of the maintenance work being done. However, simply notifying personnel is not enough to ensure safety on its own, as without physically securing the panel, someone might inadvertently turn it on, endangering those working on it.

Leaving the panel open poses significant safety risks as it exposes live wires and components, increasing the danger of accidental contact. While wearing insulated gloves can provide a level of protection, relying solely on them without securing the panel does not adequately safeguard against the dangers associated with electrical work.

Thus, locking and tagging the panel is the most effective strategy for ensuring the safety of workers involved in maintenance or repairs on electrical panels.
