Chilling Lahore and Static Charge

Did you guys notice many foreigners roaming around the city these days. May be there are here for the Cricket Matches being played between Pakistan and England or because of World Performing Art Theatre. Whether it is Anarkali bazaar or Mall Road, Liberty or Main Boulevard. Fortress or Lahore Fort. They are seen everywhere with their backpacks and most of the times wearing funny shalwar with t-shirt on top of it. Or GORI MAIMs wearing dupattas in a very unique way. Did you see so much foreigners roaming in Lahore in any of the previous matches? At least I didn

    Asslam-o-Alikum. The basic reason behind getting static shocks is potential difference between two bodies. Because of dryness during snow or winter, you get static shocks whatever you touch. The charge builds up due to friction or rubbing of two bodies against each other. Few days before I was shaking hand with my husband and we both got shocked by static charge built up between us.

    If you remember, in 8th class we used to do experiment of elctrostatic induction. We used comb or plastic ruler in our hair and then brought it close to pieces of paper then papers stuck to the plastic ruler or comb. It was because of movement of electrons from comb to paper or vice versa and thus the ruler is statically charged.

    The best way to avoid static shocks is to keep your hands moisturized as much as you can. Keep handy hand-cream in your pockets or purses and use them whenever you wash your hands. If their is moisture in air you wont get static shocks. That’s why Air Purifiers or humidifiers are available everywhere and are very commonly used in America. Though they don’t entirely help it but they work 90%. You can easily find it on internet and if you want best quality check out bestbuy.com or bedbathandbeyond.com.

    Best Wishes, Saima

    Hi Saima and Opee:

    *Partly* wrong advice. Moisturizing your hands is not going to reduce static charge that builds up during the dry season. If you walk on the carpet, while wearing rubber shoes your whole body (primarily clothes, hair) will build up and retain this static regardless of how much moisturizer you have applied on your hands.

    You are partly correct, humidifiers (not air purifiers, two different pieces of equipments) will actually increase the ambient moisture in the air, thereby increasing the propensity of charge dissipation through the environment.

    In chip manufacturing and assembly facilities, electrostatic discharge is considered a big problem. Therefore, these facilities have very expensive environment control systems, which among other things blow ionized air into the environment. These facilities cannot run humidifiers instead they keep humidity deliberately low to prevent corrosion. The workers in these facilities wear smocks (conductive overcoats) and other clothing that enhances charge conductivity and dissipation; while sitting on their work-benches they are required to wear “grounding straps”, which is like a piece of wire that connects their hands (body) to generally a metallic workbench (table) that is itself “grounded”, and the floors in these facilities have no carpets.

    The reason is that in very dry environment under “perfect” conditions a human being walking on a carpet can build up to 30,000 volts of static electricity. This is not an exaggeration but a scientific estimation. The reason it does not kill anyone because the amount of current is actually negligible, less than nanoampere.

    Therefore, it is a generally a good practice to “discharge” yourself by touching a “grounded” piece of metal before working on a computer, or touching any computer or an computer chip, because you can actually destroy it. Fortunately almost all of the modern electronic devices have circuitry put-in solely for the purposes of dissipating these large voltages [greater than 10,000 volts] that are injected into the chips via ESD [Electrostatic Discharge], so generally speaking they would not be “fried”, but it pays to be careful. Believe it or not, 15 years ago, touch of a “charged” human being was the most destructive thing for a sophisticate computer chip, that is rarely the case anymore.

    The so-called “shock” that you feel (and sometimes see the associated spark) while shaking hands, or touching a “grounded” surface is actually this electrostatic discharge or ESD. In some cases in very dry climates, along with relative in higher ambient temperatures, some people allege that ESD can ignite fuel; therefore, it is always wise to discharge yourself by touching an unpainted metallic surface before filling up the petrol in your car. But again the likelihood of that actually happening is negligible under normal conditions. In fact, in your lifetime you are more likely to destroy a computer chip by touching it, if it was made a by third rate manufacturer with inadequate ESD protection, than starting a fire in a petrol pump. Hope this helps. Best regards, always.

    You are right omer this is really an irritating and painful problem….. I have been experiencing it for about 3-4 years but this year I have heard other people complaining about it as well… I use to experience this shock while touching my car (even right after parking it somewhere and trying to close the door after getting down), touching my main gate, and to my surprise sometimes even while touching polished wooden surface in my office…. :-(….
    I searched the internet but havent found any good soution…. though there are some preventions which are stated in the following website….

    So if anyone knows about any better solution then please share it …..

    Salaam bhan / bahaio..

    I know this isnt related but I was wondering if anyone can help me. I am coming for the very first time to Lahore, arriving 1st Jan 06 with my wife and 1 yr old baby girl. Does anyone know where I can get Travelling Cots for babies please ? I have searched the internet and cant find anything, Im sure Pakistan has a lot of modern shops however they are not ONLINE which doesnt help me. Can someone please tell me which shops / centres will have ‘Travelling Cots’. A phone number of the actual shop will be really useful so I can preorder it before I arrive. Any help please would be most grateful and who knows, we might even bumb into each other when Im there.
    Jazakamullah O’khair

    i did only find the solution of this is to touch to a nearby wall before touching any doorknob or before shaking hands.

    I have been experiencing the static charge for many winters now. It is basically because of the greater charge difference between the body and the outside temperature. I usually touch my leg to any object (or door when getting off from my car) to dissipate some charge from my body and then try not to touch the tip of my fingers to any metallic object, as usually the fingers are most vulnerable to the static. Also with metals I have sometimes even seen a spark. Electrifying aren’t we.

    I was wondering why I was ‘charged’ so much lately! My shirt was clinging to ma body and my hair standing on end! Not to mention static from the car!! LOL

    Waqar, the best bet would be to get here, and then visit a large department store. Most of them stock baby carriers.

    There is also a large market of baby and kid gear (tricycles, carriers, etc.) in Anarkali.
