My body discharges electricity – health – nigeria static electricity diagram


Static electricity is generated whenever two materials are in contact with each other. All materials are made of electrical charges in the material atoms. In the universe there are equal amounts of negative electrical charge (electrons) and positive charge (protons). These generally try to stay in balance of equal amounts at every location.

However, when two materials are in contact, some of the charges redistribute by moving from one material to the other. This leaves an excess of positive charge on one material, and an equal negative charge on the other. When the materials move apart, each takes it’s charge with it. One material becomes charged positively, and the other negatively.

If the materials are able to conduct electricity away the charges will dissipate and eventually recombine. In this case, static electricity effects may be too small to be noticed. However, if the charges are separated faster than the material can dissipate them, the amount of electrostatic charge builds up. Eventually a high voltage, and the effects of static electricity, may be noticed.

Most modern shoes have highly insulating rubber or plastic soles. As you walk, static charges can build up on the soles of the shoes. This is especially true if the floor is also insulating. Some older nylon carpets are particularly good at generating static electricity.

The charge on the shoes soles induces static electrical charge on your body, and this charge appears as a high voltage. Under severe conditions, more than 15,000 Volts have been recorded. It is quite common to experience 5,000V. In fact, many people do not feel a shock from a static electricity discharge less than about 2,000-4,000V.

When you sit in a chair the contact between your clothes and the chair can generate a lot of electrostatic charge on your clothes. While you stay in contact with the chair your body voltage stays low. If you lean forward so you back moves away from the chair back, or if you get up out of the chair, then you take the electrostatic charge with you. Your body voltage can rise very rapidly to a high voltage as the charge is separated from it’s counter charge on the chair.

Secondly, you may be storing more static electricity than others. This depends on the size of your body and feet, and the thickness of your shoe soles! A bigger body, bigger feet, and thinner shoe soles, means more charge has to be stored to produce the same voltage. This gives a higher energy electrostatic discharge.

Thirdly, you may be generating more charge than others. This may be due to the material of your shoe soles, or the way that you walk. If it happens when sitting, it may be due to the material of your clothes, and the amount of static they generate against your chair.

Static charge build-up is enhanced when the air is dry. So, static problems and effects are often noticed in dry air conditions. The air outside can be very dry when the weather is cold and dry. Indoors, central heating or air conditioning can give very dry conditions which promote static electricity. Heating warms the air and reduces its humidity.

Unfortunately cure is not always easy. Indoors, you can try raising the air humidity to 40-50% rh with a humidifier. (You can check the humidity with a cheap humidity meter from a gardening shop.) Also, look for shoes with leather soles. In the electronics industry, and in areas where electrostatic sparks could cause a fire hazard, people often wear specially designed static dissipative shoes to reduce electrostatic charge build-up on the body. It is less likely that problems will be experienced with non-polymer floors, such as cement or wood (although varnishes can cause problems). However, replacing the floor can be expensive!

Once again, you build up electrostatic charge as you walk around. However, if you’re pushing a trolley, the wheels of the trolley can also generate static electricity. As you walk around, you and the trolley both store charge and reach a high voltage. When you reach to touch something, you get a shock.

Sadly, the cure is probably in the hands of the shop facility managers, who may need to maintain or replace the floor covering or trolleys. Usually they don’t discover the problem until after the floor is fitted, and it’s difficult and expensive to do anything about it.

Fortunately there is little risk attached to such electrostatic discharges. In most cases they are just a common nuisance. The biggest risk is that a shock could cause you to have an accidental injury. For example, you might withdraw your arm suddenly and hit it against something.

Sitting in the car, electrostatic charges are generated on the car seat and the person’s body, due to contact and movement between the clothes and the seat. When the person leaves the seat, They take half of this charge with them. As they get out of the vehicle, their body voltages rises due to this charge – a voltage of 10,000 Volts is not unusual.

If you have forgotten to hold the metal door part as you leave the seat, a shock may often still be avoided by touching the glass window before you touch the metal door. The glass may be conductive enough to dissipate charge, whilst preventing the rapid discharge which is felt as a shock.

The best way to prevent the build up of static on you is to ground yourself. You can do this by touching a grounded metal object such as you computer’s metal case, or, personally I use that and my metal radiator . The easiest way is to wear an anti- static wristband, which you tie around your wrist and clip it to your metal computer case, and it keeps you grounded constantly, so that any static that you charge up becomes immediately grounded.

It also helps to keep your PC plugged into a anti-surge expansion plug which is plugged into the wall socket while you are working on it (this step isn’t recommended), but REMEMBER TO ALWAYS KEEP THE POWER SWITCHED OFF WHEN WORKING INSIDE YOUR COMPUTER

I hope this page has been helpful to you. Taking all the steps is not necessary, however I highly recommend grounding yourself before working inside your computer, and keeping yourself grounded at all times. Also, never touch the bare circuitry of your components, and always handle by the edges. Protect components outside of your computer by placing them in anti-static bags. I always remove my shirt and socks when working on my computer, and I make sure I am not standing on any carpet. Pay attention to the dress tips above! Clothes are the main reason you become charged with static.

PICS will be added as soon as I get my digital camera up and running. I have some nice pics of static electricity in action planned for you, you’ll see! Last night I stayed up till about 1:30 am experimenting with a static globe and I was able to get it to burn through paper. Pics coming soon hopefully
