I removed the bulk of the lightning rod article here. Too lengthy for this article. A breif synopsis should be made with a "main" wlnk. JDR 17:30, 15 August 2005 (UTC)
Is it 25 to 33% or 10%? The second sentence implies 10%. "between 25 to 33% of those struck die.[1][verification needed] In the United States, it is the #2 weather killer (second only to floods), killing 100 annually and injuring ten times that number."

If you are in a field during a storm, should you stay in the open or hide under a tree? Either one seems fatal. Catch-22? smurrayinchester( User), ( Talk) 09:40, 22 October 2005 (UTC)
The odds that lightning will strike the tree are MUCH higher than the odds that it will strike any given section of an open plane, so by being near the tree you greatly raise your odds of being in a strike. The ideal thing to do is to be far from the tree, and then become "a basketball with feet" - crouch down on the ground, with only your feet on the ground, and your body curled up in a ball. That way, you are minimally higher than the ground and thus not significantly more attractive to the lightning. DO NOT LIE DOWN - if lightning strikes near you, the voltage potential across the ground will cause a current flow through your whole body, including the thoracic cavity and heart. By only having two small points of contact (your feet) that are very near each other, the voltage across them will be smaller than they would be across your whole supine body, and any current flow they experience will only be through your legs and pelvis - avoiding the the heart.

If you're in the middle of a forest during a thunderstorm, what should you do? -- Carnildo 08:24, 1 April 2006 (UTC)
Would someone care to add a section on lightning protection myths? You could include an illustration similar to the one here [1], showing how insignificant the height of the Sears Tower is (much less an umbrella or person) when compared to the height of a thunderstorm. Other important points to cover are that metal (other than skyscrapers or tall antennae) has practically no influence over whether or where lightning will strike, and that lightning might strike a poor conductor rather than a better conductor nearby.
I can't recall the source, but I also remember reading an humorous tale by Mark Twain or a contemporary about an ignorant couple trying numerous crazy things in attempt to reduce the risk of being electrocuted by a thunderstorm. This story might be relevant as well.
A good closing would be something to the effect that while measures might be taken to decrease the damage caused by lightning, the only way to significantly reduce the risk of electrocution is to avoid being outdoors in a thunderstorm.

FYI, I moved a lot of the info to the Keraunomedicine article, as it seemed more appropriate there. -- Xiaphias 14:44, 19 May 2007 (UTC)

I had turned and was walking away from a building when lightning struck the eave of the building and I felt something sort of snatch at the hair on the back of my head and I hit the ground without damage. So there must be a localized electrostatic field generated in the volume of space around a lightning strike that is capable of attracting matter. Is that a reasonable supposition? WFPM ( talk) 20:22, 10 August 2009 (UTC)
I agree this article is lacking description of some key measures for personal prevention, the chapter about this is written with a perspective/assumption of a prior knowledge, or that everyone will read the whole article and would be able to figure things out by themselves. Something along the lines how to exclude oneself as a preferential pathway for the lightning and how to best protect oneself from 'step potential', especially in cases when one has got no option of staying in/going to a car or house, would be useful? 2.99.250.225 ( talk) 08:45, 11 August 2013 (UTC)
It is claimed in Germany around 100 ppl are injured by lightning /a. It seems to me that only the industrial nations with proper infrastructure actually report correctly and that the real world figure is probably far higher. Slicky ( talk) 09:27, 15 August 2009 (UTC)
It needs to say which it is. Are you ready for IPv6? ( talk) 10:55, 26 May 2010 (UTC)
Can't seem to find anything on fires in the main article. There must be a vast number of fires started by lightning annually just in the USA. The article below says 31,000 annually, from 2002 to 2005. And 12 deaths. The article also says nearly all lightning-started fire civilian deaths were from house fires.

The paragraph title incidence of lightning strikes fails to state or comment on the incidence of 'lightning strikes' whatsoever, instead going on about the incidence of 'fatalities or injuries from strikes'. This is not a specious distinction. Writers needed badly! 76.6.78.16 ( talk) 04:55, 24 April 2011 (UTC)
How about a history section?
I'd start it myself if I knew anything. SSSheridan ( talk) 16:54, 20 April 2012 (UTC)
I suggest that reference [15] is removed as it no longer relates to the subject (the pointed by it webpage has changed and carries no information related to the subject).
Plamen Grozdanov ( talk) 14:25, 8 August 2012 (UTC)
Update: looks like the referenced webpage has again become relevant -- there is a small paragraph about lightnings. Thus, this reference could be kept (although I am not sure that it meets the high standards of Wikipedia). Perhaps we should remove it?
Plamen Grozdanov ( talk) 22:54, 26 September 2012 (UTC)
I am going to start working on overhauling this article... to much common beliefs and often erroneous information, not enough documented science and verifiable proofs are used. There are so many contradictions from section to section, and even within the sections themselves.
Case in point... Trees.
I'm going to tag this page, needing revision & cleanup. Can we stick with science, accurate terminology and documented evidence in our revisions please? I am also working on the lightning page, as well as many pages related to lightning. I have no qualms about revealing I do work in the lightning protection industry, however at all costs & with considerable effort, I attempt to limit any direct Conflicts of Interest, choosing documented science or industry practices as my guidelines.
ps... I don't intend to get into a edit warring match with other wikieditors involved with this page, but I can see the potential of this occurring. The "Personal Safety" section appears to be best available knowledge, but sourcing solely to the NILS raises eyebrows... given their list of referenced "papers" contain more "discredits" and legal battles against "non-traditional" lightning protection systems; and single example case studies promoting lightning rod effectiveness; national and international regulations defined by legal precedent or insurance industry findings; than it does about reporting scientific inquiry into lightning itself. Because so much is still unknown about lightning and very little of this understanding is definitive, lightning protection is much more political and about dollars and cents, than an unassociated person or someone wanting to simply convey the most unbiased understanding available, would like to admit, but it exists. Question everything goes without saying. Borealdreams ( talk) 19:26, 16 March 2013 (UTC)
The article is loaded with improper grammar, confusing sentence structure, and incorrect punctuation to the point where meaning is being lost and information is lost. Case in point: "And the entire flash, lasts only a few fractions of a second, most of which is not visible to human eyes." This sentence tells us that "fractions of a second" are not "visible to human eyes," as the verb does not agree with the subject. (We have to infer that we cannot see most of the flash.) And then comes "Just like lightning, that deceives our eyes, usually looking larger or closer than it really is, the earth's atmosphere and our brain's perception of the outside world, ultimately determines whether it is "heard" or not." That disaster of a sentence is so jumbled that I cannot tell what it ultimately means to communicate.
As I am not an "expert" on the subject, I don't feel I am in a position to rewrite the many sentences needing rewritten in this article, lest I misconstrue meaning. (And given how poorly some of this article is written, it's a possibility.) But I would encourage someone who knows and understands the subject better than I do to give this article a good editing for meaning, grammar, structure, and punctuation, as much of it is a mess. Fiddlecub ( talk) 05:43, 4 April 2013 (UTC)
"Thirty-six-and-a-half seconds after lift-off, the Apollo 12 Mission's Saturn V rocket and its ionized exhaust plume became part of a lightning flash channel as it terminated on earth. Discharge occurred "through" vehicle, however it did not affect instrumentation or ignite the rocket's highly combustible fuel. Due to the rocket not being "grounded" as it was in the middle of the atmosphere, electrical potential does not exist, passing relatively benignly "around" the unit, just as "birds on a wire" are similarly unaffected." Yes, exactly like airplanes, which totally aren't certified to withstand the 200,000 odd amps a lightning strike puts through the airframe. (spoiler: lightning protection is the whole point of a number of FARs) We need an actual source for this one. 68.103.185.180 ( talk) 23:56, 22 May 2013 (UTC)
The statement was erroneous - I've removed it and reworded the paragraph a bit to improve clarity. Bert ( talk) 13:39, 20 October 2013 (UTC)
The whole "the electrical current staying with the body and as a result limbs and other parts of the body may glow" smells quite fishy to me. For one, a "current" can't "stay" anywhere - it would no longer be a "current". Besides, it's rare for charged objects to glow because of the charge, as is for objects through which a current passes (barring incandescence, which would probably mean death, or LED-like effects, which require semiconductivity). It does not seem likely that a person can be charged enough to ionize the surroundings and survive... Any source for that affirmation? Andvaranaut ( talk) 10:35, 3 September 2013 (UTC)
No mention of joules average range for each type of strike. — Preceding unsigned comment added by 97.115.151.61 ( talk) 14:50, 23 June 2014 (UTC)
In the first paragraph it states that ground to cloud (GC) flashes are more common than cloud to ground (CG). This is erroneous. Charges much more commonly originate in the cloud and propagate downward, whether they be negative or positive. "Cloud-to-ground lightning is the most damaging and dangerous form of lightning. Although not the most common type, it is the one which is best understood. Most flashes originate near the lower-negative charge center and deliver negative charge to Earth." [1] Samuelspraker ( talk) 17:35, 26 August 2015 (UTC) 17:05, 26 August 2015

What does the L~ at the beginning mean? How is it pronounced?? But maybe it is just a notation meaning "the (first) word of the lemma", which is used sometimes in printed dictionaries to save space ... but this is not a WP notation, I'd say. Can I remove it, or is there some magical, mysterious and absolutely well-founded meaning behind this? -- User:Haraldmmueller 10:26, 26 March 2016 (UTC)
