Of all the things us electricians do daily that can get us hurt, or worse, getting shocked is at the top of the list. In today’s episode, Dustin tells us about his worst experience with getting shocked and also shares a few tidbits of information that can help us understand WHY we get shocked & how to not let that happen.

As with many of us, there are horror stories of the worst shock we received. For Dustin, he was working alone underneath a house, laying on the dirt that was soaked from recent rain, he was working with live circuitry in a j box, and had maybe 3 years in the trade. He tried using a voltage tick tracer to tell him when the circuit was shut off, but it gave a false reading leading him to believe that the circuit was not energized. A wire fell out of the j box, landed on his chest, and since he was in direct contact with the earth, he received a wicked shock. So, how could the incident have been avoided?
In the scheme of things, we should NEVER work on energized circuitry unless it is absolutely necessary (we are troubleshooting & need to have the circuit energized to see what it is/is not doing), we are testing and need the circuit energized to get values, or there is greater damage possible to property/humans well-being AND we have the proper training to work on it. Shutting the circuit off is the best way to avoid a shock. In addition to shutting it off, a proper LOTO (lock out tag out) plan should also be implemented, so there is no possible way that the circuit can be reenergized while we have our hands on it. This could be installing a breaker lock/tag or padlocking/tagging a disconnect in the off position, or something similar. A tip if working on a fused disconnect- take the fuses OUT when working on the circuit (in addition to locking it out) so there is no way that the circuit can make it all the way to you even if the disconnect is unlocked.
Another thing to keep in mind is the way we take care of and use our electrical testing devices (meters, voltage tic sticks, etc.). Do NOT just throw your testing equipment in the back of the truck leaving it susceptible to the elements and damage, throw it into your truck toolbox, or in the gang box and pile other tools on top of it. Our meters could literally be used to protect your life and should be treated as sensitive equipment. They should be kept in a separate box/bag/etc. and cared for. They should be tested fairly frequently on live circuits to check if they are operating properly and the batteries should be replaced on regular intervals. When using a meter (or a hot stick) to see if a circuit is de energized, they should first be checked on a live circuit to verify they are working, THEN check the circuit you are working on, AND then rechecked on a known live circuit. This will ensure your meter is operating properly.
IF working on a live circuit is necessary, a couple of important items should be taken into consideration. Do NOT work it alone with no one around. Make sure that another qualified person is available and knows what you are attempting to do. You should also be properly trained in the working of live circuits so you recognize and avoid the dangers. Proper PPE should also be used and will be task specific. When in doubt, check with your safety representative, your supervisor, or veterans of the trade. Keep in mind that electricity will always look for the shortest path to make a complete circuit, and if you insert yourself into that loop, you are going to receive a nasty surprise. Make sure you are not standing in (or laying on) a puddle of water or saturated soil and make sure your other body parts are not touching anything grounded, a neutral conductor, or another circuit.
We hope this has been helpful in understanding some of the ways you can receive an electrical shock and how to avoid them. At the end of the day, we are working to support ourselves and our families and if we get hurt (or worse) by getting shocked (when it could have been avoided), then we would be working for nothing!
