Showering during Lightning storm?

You know someone had to bring this up, and being that summer is just about upon us, tis the season...

All the while growing up, I was warned by my mom not to shower, or even go near plumbing or electrical appliances during a lightning storm.
Now that I have grown up, and understand a lot more about electricity, I am asking myself whether or not this warning was just a myth, or is there some truth to it.

I Googled the phrase "struck by lightning while showering" and did come up with some hits, but they are few and far between, and mostly in the mid west where storms get a lot more severe than they do here in NJ.

Most, if not everyone I have ever brought up this question with looked at me as though I were an alien from a distant world.
I realize that in order to get enough current in your plumbing system to cause electrocution in the shower, the house would pretty much have to be hit directly.

I would also think the chances would be at least partially dependent on how well the building's electrical and other metallic parts are grounded.

What do you think?

I think you might want to understand current flow, ampacity, a little better:

1 milliamp Just a faint tingle.
5 milliamps Slight shock felt. Disturbing, but not painful. Most people can "let go." However, strong involuntary movements can cause injuries.
6-25 milliamps (women) and 9-30 milliamps (men) Painful shock. Muscular control is lost. This is the range where "freezing currents" start. It may not be possible to "let go."
50-150 milliamps Extremely painful shock, respiratory arrest (breathing stops), severe muscle contractions. Flexor muscles may cause holding on; extensor muscles may cause intense pushing away. Death is possible.
1,000-4,300 milliamps (1-4.3 amps) Ventricular fibrillation (heart pumping action not rhythmic) occurs. Muscles contract; nerve damage occurs. Death is likely.
10,000 milliamps (10 amps) Cardiac arrest and severe burns occur. Death is probable.
15,000 milliamps (15 amps) Lowest overcurrent at which a typical fuse or circuit breaker opens a circuit!

If your house have all copper pipes and grounded and bonded properly the lighting will take the shortest route from sky to ground.

Yeah I do live in Great Northen Plains area and from time to time we do get pretty ugly thunderstorm with alot of lighting as I mention again if properly bonded and grounded it is not a issue but any more facts that part I do not know if any one got hit by lighting in shower time so that is a open question.

BUT I heard story and I think I may have a confirmed case about the telephone lighting strike somewhere not far from me { how long ago it was that I think it was early 90's that the last time I heard }( I think Mythbuster try that one I don't recall if they got thru or what )

Myself I did took shower during thunderstorm few time yeah all my copper pipes are well bonded and there is no PVC in the water supply. it feel like monster Fardey cage but normally a common sense useally tell me not to take the shower during the thunderstorm due somecase it will turn worst than that.

Merci.Marc

Even though you did not seem to answer ke2kb's question directly. But since you mentioned the various effects of electrical current through the body, it's in place to mention that in wet and other potentially hazardous locations the NEC requires installation of a GFCI outlet or Circuit Breaker! Those devices open the circuit when they sense 5 milliamps of leakage current. As opposed to 15,000 ma. The regular breaker is meant to protect against overloads not against leakage current!!!

as yoyo implied, lightning is going to do what it wants to do. I have seen it hit the ground next to 80 foot tall trees; why?

Why the lightning travels the path it does is a lot of guess work and due to the extremely high voltages involved, impossible to replicate.

Bottom line;

you most likely could be killed while in the shower if lighting struck and passed through your house in any way.

is it common; no but neither is death by a komodo dragon but that doesn't mean I am going to go taunt one and chance being the next statistic either.

there are things in life you just don't chance of you do not have to.

Mythbusters did a thing on it once.

The bottom line was that even being near a conductor that gets struck by lightning is enough to induce currents high enough to kill you.

About the path it chooses... the conductive path in air actually forms relatively slowly before the strike itself. Tendrils of ionized air sprout up from the ground and down from the clouds, getting blown around in the breeze, hitting warm and cold pockets of air, etc. It's only once these growths touch that the actual bolt forms. It's why you see so many "dead ends" in lightning bolts... those were the paths that didn't get taken.

FWIW, I'll stay out of the shower and away from my AC circuits when the thunder and lightning are simultaneous.

The one time we had what appeared to be lightning damage, nobody was here, so we don;t know for sure what happened. The AC circuits are all over-protected with surge arrestors (and a huge grounding electrode system) but it appears the current snuck in via co-ax from two sat dishes (TV and internet) and via an ethernet cable that runs from shop to house. At least everything attached to the co-ax and to both ends of the ethernet was fried whereas there was no damage to anything attached only to the AC circuits.

I'm not sure about bathing during a thunderstorm, but I can tell you first hand that you can get "struck" through the telephone line.

When I was about 15-16, I was talking on an old phone-company style "Trimline" phone with a metal bottom on the base. I was talking to a friend about 5 miles away during a gnarly lightning storm. We were both watching and talking about the storm, and I was carrying the base while moving to a different room (to look out a different window, I suppose), and there was a very close strike. There was a very bright flash and in the same instant, I got quite a jolt through my fingers from the metal part of the base. I yelled "ahhh!" and dropped the phone. The call didn't disconnect though, and the phone was still fine. Friend on the other end said he heard a loud "pop" come through, then the "ahhh!"

Ever since that day, I've tried to avoid using a land line telephone during a lightning storm, unless it's the cordless variety.

I also prefer to wait to take a shower/bath if there's a severe storm. Why tempt fate? (And I'm probably more interested in watching the storm at that moment than I am in taking a bath.)

I remember those phones. They were virtually indestructible.

I have heard of people getting jolted from landline phones during strong/severe storms.
I would also suspect a better chance of equipment damage from a surge that enters on an ethernet line than a power line, due to the higher impedance of the ethernet.
My brother lost some computer equipment that way. He was plugged into a surge suppressor, but there was nothing protecting his ethernet.

I've now got a whole-house surge suppressor, as well as POU units on all computers and audio/video equipment.

Fascination w. thunderstorm/lightning

The gonagle 5:10pm.; Since you mentioned that you are interested in watching thunderstorms unfold, I'm recommending a book on the great Electrical Engineer Nikola Tesla, who lived around the turn of the past century, in NYC. It's called simply "Tesla"! He, too was entranced every time there was a Thunderstorm with lightning strikes. Among other things, he was taken advantage of by Thomas Edison, who promised to pay him if he completed a certain project. When he was done, T. Edison didn't give him One Dollar for his work.:laughing::yes:

I have to ask myself; why do I question what is safe and what is not, and when precautions should be taken to avert what seems to be a very unlikely, but still not impossible accident.

I have always respected electricity, and especially high voltages, of which lightning tops the list. The thing I have to remember, is that lightning is utterly unpredictable. I can prevent an accident while working on my SE panel by taking the normal precautions, but in that case I know what I am dealing with. 220V isn't going to suddenly do something unpredictable. It will always do what it is "supposed" to do.

But I have actually seen accounts on TV (TWC) where a guy was struck by lightning while riding a bicycle 50 miles away from the storm!
You probably saw that on TWC a couple of years ago.

So, in the end, I will continue to practice what I have practiced all of my life and stay away from the shower, and other points of entry during a lightning storm.
