That means it's grounded, but you're not. You accumulate static from the belt of the treadmill, similar to shuffling along on a carpet. The shock is what happens when you ground yourself out.

Irritating? Yes. Dangerous? Not for something like that. I think it is possible to build a large enough VDG that can store a dangerous charge.

You might be causing more of it with the compound of your soles or running without picking up your feet.

If you run for a bit and then touch the control panel, heartbeat monitor interface, or brush against any metal on the chassis, you get a shock. The longer you run without touching anything, the more piss it will shock out of you when you finally do brush against a screwhead or something. Wear a grounding anti-static bracelet to discharge yourself while using the treadmill.

We used a 6" diameter high vacuum hose to clean fly-ash out of a hydro plant's boiler before. I stepped over the hose during work and it was more than happy to shoot a static arc and get me by the johnson. The sweat in our steel toe rubber boots was also causing discharge through the soles to the steel floor of the boiler interior. The electrical pulse feeling in your feet was all sorts of weird. We tried all sorts of grounding methods, but nothing completely solved the problem when you're essentially sucking up baby powder with a hose that will rip the clothes off your body.

The longer you run without touching anything, the more piss it will shock out of you when you finally do brush against a screwhead or something. This is actually caused by worn out brushes in the treadmill. You're right in the Van De Graaf analogy, but typically treadmills mitigate this by having a series of copper brushes installed under the belt to ground it. These wear out with time and need to be replaced or you end up with the situation you're in.

Yes, it is more likely the common point of failure is every single treadmill's maintenance in a row of 20 rather than the user's shoes or running technique.

This puts enough air into the poo poo (called "mixed liquor" lol) that if you fell in you would sink to the bottom and not be able to swim. You would just try to clamor up the wall until you drown.

Compared to the author using the wrong shoes or shuffling their feet, no. The scenario I imagine is novice runner wearing Pumas at 24 hour fitness. You know, the casual line of Pumas. Treadmills are high impact for the exercise. Running is decent outdoors, but in a fitness club, ellipticals or stair machines are a better choice. That's why I say novice runner. I'm just a skeptic and I could be wrong. Anagram of GINGER fucked around with this message at 17:18 on Aug 16, 2015 |

You know, the casual line of Pumas. It is a military gym and it is not unlikely that the treadmills have only been maintained enough to keep the belts moving. Most of the equipment is at least visibly broken (cracked dispplays, etc.), and I know how to run so there isn't any shuffling. I didn't know there's a belt static discharge brush system. That's pretty cool.

quote:The clip dates back to 1990 and has been taken from an internal BBC training video issued to presenters to make them aware of the perils of the job. It was originally recorded from a live item broadcast during one of the Saturday Morning Kids' programmes on BBC1 (I think it may have been "Going Live"). Anthea was to compere the coverage of the Royal Tournament, and a piece-to-camera had been arranged where she would do a competition link, and at the end there would be a spectacular explosion and a motorcycle would drive out of the back of the lorry parked behind her. The rear of the lorry had been hung with a nitrated (semi-explosive) cloth to hide the motorbike (and Anthea from the rider's view). The cloth would be destroyed by a theatrical thunderflash (a powerful firework used by the Army to simulate grenade explosions in training) which would be detonated by the rider on cue. The director told Anthea to sit on the tailgate of the lorry to do the piece, and of course when the rider fired off the thunderflash, the blast from it and the nitrated cloth set Anthea's hair and mike alight. Fortunately she had the presence of mind to drop off the tailgate, or the bike would have hit her as well. She sustained second degree burns and temporary loss of hearing, but sucessfully sued the BBC and the director of the piece. As a result, the BBC put safety measures in place which included the video the clip comes from.

How heavy are excavators and other heavy construction equipment? How much kinetic energy do they have traveling at highway speeds?  The answer is lots. Lots and lots. Enough to carve through steel reinforced concrete overpasses like warm butter.

Here's a thought: that digger got ripped off the flatbed that was carrying it, if it was something actually welded onto the vehicle that hit the overpass it probably would've punched straight through.
