Just been doing some surfing and this story came up.
It's about a month old but well worth a read.
It's here.

Hope he doesn't handle JET-A1, JP-1,or Avgas when he had that charge on him. It'll be *ugly*

LOL! A current of 40,000 volts? Mike, you're a fireman, what are 'static field meters' calibrated in? Have you got one in your vehicle? How do you charge the di-lithium crystals? You gotta watch out for that spontaneous combustion, it causes stuff to self-ignite!

...Firemen took possession of Clewer's jacket and stored it in the courtyard of the Fire Station, where it continued to give off a strong electrical current...


ROFL! Imagine! All that current pouring out of that poor bugger's coat and going to waste down the drain!

Conclusion? An absolute load of crap, but a good laugh!

Alan,
I don't think that this story was actually "made-up".
I have some mis-givings about the way it was reported though.
Most Fire-fighters that I know, know the difference between Current and Voltage.
And I'm not going to engage in a Trans-Tasman tirade about Aussie FF's either.
Clothing of these types can build up quite an appreciable charge.
I'm actually wearing a Nylon T-shirt at the moment, and aside from being moderately uncomfortable, it gives a huge static charge in dry weather.
I touched the Stainless sink-bench here this morning and I swear I saw a blue spark jump from my hand to the sink (which is bonded to Earth) and a bit of a slight crackle.
Now, combine that with wool, wool(Or sheeps fur, if you like Sven ) is quite popular down here for garments.
With them two materials rubbing together,
It would take no time at all to build up a good charge.
BTW Alan a Static Field Meter is calibrated in kV.
We don't carry them on our pumps, the nearest thing to that that we would have is a Modiewark HV Line Indicator, that measures up to 66kV.

I think we might need to allow for the usual journalistic license here.... (I'm trying to put that in the nicest way possible ).

Still, it does illustrate at least one advantage of our damp English climate!

Journalistic license? Enough static charge to melt a carpet? Pull the other leg, it plays "I Believe" in stereo.
See;

But, take one small tin of lighter fuel and a gas lighter........, now you're talking science!

G'day Trumpy, I think "Stuff" is the online Christchurch Star and I read it all the time. Its a reputable newspaper. I hadn't seen the article you mentioned, but I'm going to look into it because Stuff doesn't usually print rubbish.

Trumpy, something to consider in this thread would be the Nor'west weather pattern in the South Island and its effect on static electricity. Victoria also experiences a similar weather pattern.

That phrase was coined by a John Savage, (wherever he is now), when I was in the Senior Scouts. 'I Believe' had been a popular song then; this is before The Bachelors; Jimmy Young?
Further research reveals that I might be eating humble pie on the static question of melted carpet, if ( big IF! ) the victim's coat was not only able to generate static, but was constructed in some way such that it emulated a Leyden Jar?
