Shock adikkudhu Sona

(Pic adopted from wikipedia)

I am referring to the doors (or rather, door knobs) I am encountering here. Thanks to the cold and dry weather, I get 'shocks' when I touch the door knobs often. Static charges build up over a period of time in our body through the dry air and on the skin. Through the metal on the door knob, it gets discharged. It is a not-so-funny and a unique phenomenon. Never heard of it in India.. The effect is more when
a) when one is wearing shiny jacket, such as the ones made of rexin
b) when one gets lotsa friction with a fabric
c) the room has some high-voltage electrical or electromagnetic equipment
d) when the temp (less than 5 C) and the humidity (less than 30%) are low

It reached a peak when I saw a tiny spark while touching my car window.. Serious.. I must have been fully charged up... Cellphone explosions due to the static discharge has been somewhat prevalent.

Some tips on minimizig/avoiding the shocks:
i) Try to grab the knobs or any metal thing with the palm, rather than delicately touching through the fingers.. More the surface area for discharge, less will be the current density.
ii) Usually the doors have a glass window knitted with metal wires. Running your fingertips on the glass for about half-a-feet would smoothly discharge it through the glass.
iii) If you already have a leather jacket, use it; I am not recommending buying a new one (my previous post would say why).
iv) After wearing/removing any other jacket, walk up to the door, discharge in the glass window and come back to ur place. You can get shock from any metal object you touch.
v) Try not to use a cellphone near a gas station.

Have a good (shock-free) weekend, friends!!! :-)

Raju, I always get shocks when I close my car door, could u suggest something to prevent that? I always try to close the door by pushing on the window, but sometimes i still get static shock. I didn't understand the 2nd tip, maybe that will help me out. yeah, it dangerous, sometimes, i saw on tv once, a women was going to fill gas in her car, and when she was filling gas, suddenly a spark came due to static electricity, and she caught on fire.

Really nice tips..thank you..! Static can cause havoc near gas stations.!!

Shock adikkudhu Sona... LOL :)

Aiyo, indha winter vandhaale indha thollai dhaan! When playing in indoor(plastic) slides, my daughter gets highly 'charged' but she'll hardly bother. 'Engalukkudhaan pada pada-nnu irukkum'!!

Prabhu, its my pleasure.. BTW, peyar maatram pathi gazette-le potteney, padikkalaiya, illey marandhutteengala? :-)
Nitin, mm.. the tendency to get shocked also depends on person-to-person.. To prevent getting shock from car, I would recommend you to run (rub) ur fingers on the side glass windows of the car.. I also nowadays close the car by pushing the window, carefullly avoiding touching of any of the metallic part. Touching the car door using the palm will also help.

Touching the car door is not a real discharge, since it is 'only glass', no metal contact unlike the building doors. Moreover, since the car seats are made of some synthetic materials, rubbing on them while driving, charges one. Thats a reason why leather-seated car is better.

I rephrased the second tip, is it clear now? The gas station incident you mentioned is very unfortunate. I (would suggest) discharge thoroughly before filling the gas.

Narayanan, its my pleasure. 'Havoc' is the apt word for it.

Aparna, another reason why I hate winter here. mmm.. I didnt think about children in this aspect.. Have you felt discharging when you touch her? Just curious.. Their tendency to withstand mild shocks worries me too.. but then there are million kids here, illaiya? May be one needs to static-train them along with potty-training.. :-)

NaiKutti said...

raju... bglr itz so common atleast for me :-)... i am apparently "charged" up in office i guess

tt_giant said...

this may sound strange, but nowadays, when i drink water from the water-fountain in my gym, i get shocked not from the metal, but via the water, straight into my mouth!!..

narayanan said...

one question:

v) Try not to use a cellphone near a gas station.

why this?


Raju said...

Narayanan, when one is highly charged up, there is a chance that contact with the cellphone might result in the explosion of the battery. This happening near a gas station. There was an e-mail a couple of years ago warning of such accidents, which was later claimed to be a hoax; but, IMHO, it is still highly possible. I have heard of battery explosions of mobile phones in India; and the static discharge can certainly cause the battery explosion. That belief strengthened when I saw the spark from my finger tips.. Why risk? varumun kaappom..
