Introduction to NFPA 70E (2021), Part 1: The Electrically Safe Work Condition
HTML-код
- Опубликовано: 13 окт 2024
- Knowing how to establish and verify an electrically safe work condition is one of the most fundamental and important concepts of NFPA 70E, and this video focuses on how to do it.
*At approximately the 9:00 minute mark I incorrectly stated that the equipment was energized at the time. I was made aware today that the equipment was de-energized. I apologize for the confusion
Great content. !! I always thought a hospital with life support equipment is a definite situation where shutting off equipment is a greater hazard than working hot. Learned something important to consider.
The best NFPA 70E content I have come across so far.
Thank you, Ryan. Your videos are going to save my life some day, maybe.
Ryan, your pictures and common sense approach makes it very simple for the average supervisor to grasp. Keep up the good work! I would give your video two thumbs up, not just one.
Good job Ryan; I look forward to seeing your other Electrical Safety videos.
Another great video sir...!!👍
I didn't know May was electrical safety month. I will share this information with my service department colleagues.
Thank you...!!
Edit: 42:00 great points about remaining battery power in your test meter. I've seen weird readings when battery's running low...
Invaluable knowledge I'm looking into to starting an apprenticeship and wanted to know the general saftey information I might need. Very very informative especially having the whole procedure down on how to create an electrically safe work environment. My father was injured in construction not from an electrical accident but still it changed the coarse of his life and stopped him from doing what he loves and I don't want to be in the same position. I take saftey very seriously and really appreciate the videos.
You will get hazed so hard for being safe. Not saying it's right, but it's what happens. Get ready for it. Don't give in - peer pressure isn't worth your life. You only have to be wrong once.
Excellent and very informative!
Q: If this video is about NFPA 70E-2021, why above your inset, do you show the cover of NFPA 70-2020 rather than the cover of NFPA 70E-2021?
Because I screwed up :😀
thank you for the great content. I really enjoy your choice of words and your contents.
Really appreciate you doing this Ryan. Electrical is always a shocking subject for us, but you've helped a lot with my Facility work.
This comment hertz
Thank you. Great content!
I'm very interested to see an example of using the category method for arc flash ppe selection and the associated need for confirming available arc current and breaker opening times.
That is very much on the agenda.
Tomorrow (5-6-21).
Ryan, I love this series and have learned a lot.
A question concerning PPE and shock protection. If working in a live 240v panel with an incident enegy of .1 cal/cm2, is the only 70E requirement for PPE to wear insulated gloves and class E hard hat (130.7 C 1-9) for shock protection?
Great Videos! I watched Part 1 and Part 2. Are there any more? I am focusing on NFPA 70E and trying to gain my CESCP certification.
Hi Jeffrey. I haven't made any other 70E videos, sorry. I mainly focus on the NEC.
Ryan, you are a miracle of God's infinite love.
Great video! Everything explained very detailed. Thank you very much!
Thanks!
Thanks Rick!
Great video man. I got plenty of excuses not to work hot and be safe.. thank you
Can you walk up to the disconnect switch or panel board in normal condition and flip the switch? you said yes, was that with PPE or without PPE on? If it can be done without PPE on then can you turn on and off switchgear draw out breaker with panel covers ON. Ryan, your videos are great!
Really enjoyed this.
Ty.
Really good explanation. Thank you
14:25 Makes sense. Great way to put it.
Thank you for this series! Also, go Utes!!
Thank you mister Jackson
Thanks , very helpful content.
Hi Ryan, have you done a video to help pass the CEST exam ?
Not specifically, no.
What is the highest live voltage an electrician can safely check with a handheld voltmeter per NFPA70E?
What is the arc flash rating of metal sheet based on material and thickness
Thanks for this presentation
Thanks good graphics and everything
Please make tutorial video on ARC FLASH
Thank you Ryan !
Very good one. Thanks a lot.
16:30 Also working in a data center!
Is interesting to me. I'm getting old(52) and have sort of a built-in consciousness of these things but feel like a buffoon for not knowing the latest 'E' methods'. Yea, I buy it and read it but the common sense of it has not changed much. I knew a 73 y/o plumber that dropped a tool into a 480V, 1300A electric boiler. Burn and roll after that and I bet he'd rather have died after. He did not die. 9 months of hospital at age 78? Yea, I think I'd rather have been done at that point. Serious issues but the basic issue is constant and unchanging. Oh yea, I'll buy and review the 21 version for sure and review the 'new' discoveries' but as I get older, I'm not sure that there is really anything new.
Thanks so much
"..Oh, 70E..you can't turn on a light switch without PPE.."
Well, you definitely can't plug in a hair dryer, or any other 15A 120V connector plug without PPE in 70E :)
I'm talking too much but this subject brings up much pain for me. Commissioning things...e.g. new panels I designed. I get to do that. Oh what fun. But, I designed them and inherently know(at least I should) know the risks involved and take(from my point of view, the proper precautions). Then comes the question of 'qualified person'...an ill-defined entity and sort of self certified in NEC. I love(not) that piss-poor definition. Anyway, I designed the stuff so my male-ego and conscience says I am 'qualified' Then a 'safety' guru comes around and needs proof. I give it, (she[mostly] hears it) and then we're on our way. Damn, I love this and hate it too. I embrace safety but sometimes feel like I am painted into a corner....Real world stuff I get to embrace every week or two. Stall production on a safety issue and you are looked at as a hindrance to goal. That kind of psychological BS is very very real.
Ooof, let me be more direct. The NEC becomes smarter every three years because they force it. Sorta questionable practice, IMO. I certainly comply but question the regularity of increased knowledge. I respect and appreciate updates. However, physics is stable for the life of the universe...does not change every 3 years. I have every 3 years of paper for the last 20 years. Hard to keep track of. Addendum, not code in entirety would be much easier to follow.
