My dad is a retired union electrician and he told me stories about the old timers testing circuits by touching conductors with fingers. Thankfully he never did that. A better rule of thumb if you will, is to always have tremendous respect for electricity.
Many times they used the back of their hand, the theory was if the conductor or object was live their hand would contract away from rather than grabbing and preventing letting go. Of course this is not recommend practice today and was many years ago before we really understood the dangers of electricity and had suitable meters widely available.
Watching this leaving a funeral viewing for my (electrician) journeyman that was electrocuted Friday. Please take safety seriously. RIP Carlos. IBEW 716.
Thank you for doing Safety videos. The Techs I work with here in TN. don't take safety seriously. They try to be macho, but I think it's because they dont know any better.
this stuff is important because with how much knowledge available on the web there's enough to make people to go at it without being really "qualified" legally. "Qualified" to me is just knowing what you're doing. being certified is good, but it's not necessary.
7:22 The video is dated 2018 but the Category 0 was removed in 2015. I don't know if this video is outdated but more importantly, why don't we see techs in the videos, while measuring voltage with exposed energized parts and conductors greater than 50V, wearing any shock protection? Why does the workforce treat Electrical Safety like Electrician Safety? HVAC techs are exposed to the same hazards as electricians while measuring voltage, but not wearing any electrical safety PPE. When will the HVAC industry start implementing electrical safety work practices?
Also do not rely on the disconnect...look inside and verify that that line side hasn't been jumped over to the load side essential making the disconnect irrelevant...i know its dumd AF but I've seen this multiple times. Make it a habit to open that disconnect door when you use a disconnect to isolate equipment..
I was taught to always verify with my meter on the load side of the disconnect (L1 to L2, or L1 to L2 to L3 if 3 phase) that no voltage was present, because you never know. I go a step further and check for voltage where the load wires coming from the disconnect are connected to the contactor. You can never be too safe with electricity, as I prefer being alive over turning into a Roman candle. 😀
I don't agree with being tied the ladder, the only reason I'm alive today is because after being stuck there electrocuted through both arms for 3 seconds i fell off the ladder.. and thank god like those grabbing claw machines i didn't get a good grip on the suction pipe
When I was a kid 3 I put a car key into an outlet. I was a dumb kid. I felt it travel down my arm down my body and through my leg. I have no idea how I survived probably gfci

Great short info. Very helpful!
Thank you. Some great tips.
Thank you for the safety video
Also be aware that > 600 volts skin will be breached allowing your iron rich salty blood to now become a very low resistive path for current flow.
excellent channel!
I would love to have the American Electricians Guide

Never, lmao. They're just gonna keep dying.
Sir Q what are the criterias selection of electrical equipment in an organisation? How will inspect that area?

Hey,
I like your lesson.
Great job again like always
What are the main safety risks regarding high Voltages (>50 Volt)?
Fun fact, low voltage causes more death than high voltage
@@tardnation2670 this is not true at all.
have a sacrificial electrode nearby connected to ground. any arcs will go there, not you.
3:53 you mean "shorted", not "grounded"
If you become a part of a circuit you will pop as a fuse
Watching this *after* having received a shock... sigh
