Many people, even experienced electricians, have been killed or seriously injured while opening electrical panels. In 1991, an Atlanta electrician was killed while attempting to inspect a panel that had a faulty spring-loaded bus-bar assembly. Apparently, the bus-bar was moved while the electrician was opening the panel, causing an arc and a lethal electrical explosion. Generally, two factors contribute to these situations: defective components and complacency. Inspectors must be aware that all forms of electrical inspections, especially electrical panel inspections, are inherently dangerous. Practice calm, steady movements and learn to avoid distractions. A sudden flash, shout or movement could cause an inspector to lunge and touch an electrically live and dangerous component. Advise your client that they should never remove an electrical panel cover themselves, as they should leave this duty to InterNACHI inspectors or qualified electricians. Before touching the electrical panel, inspectors should ask themselves the following questions: Do I have an escape path? Make sure that you know where you can safely turn or step if you must safely escape a dangerous surprise, such as bees or sparks. An unfortunately placed shovel or extension cord, for instance, can turn a quick jerk into a dangerous fall. Are the floors wet? Never touch any electrical equipment while standing on a wet surface! Does the panel appear to be wet? Check overhead for dripping water that has condensed on a cold water pipe. Moisture can arrive in more ways than you can imagine. Is the panel rusty? Rust is an indication of previous wet conditions that may still exist. As an optional safety measure, use a voltage ticker to make sure the box is safe to touch. If the alarm sounds on the device, have the box examined by a qualified electrician. Also, safety glasses and other personal protective equipment may be used to protect against burns and electric shock. While removing the panel cover, inspectors should: Stand a little back while removing the cover, which makes it easier to remain in a blocking position.Stand so as to block your client from touching the panel and its components.inform the client that opening the panel is a dangerous step, and that if sparks fly, the client should not touch the inspector
