Synopsis

This information explains why we get small electric shocks from static electricity, also called electrostatic discharge, and what can be done to stop them. It describes how charge builds up when different materials rub together, why cold, dry air and insulating shoes make shocks more likely, and gives practical tips for the home, the car, shopping carts and bedding, such as raising indoor humidity, using hand lotion, choosing cotton over synthetics and touching metal with a key first. It also covers wheelchair users, whose rubber tires can let static build up, with simple ways to drain the charge. The advice is useful for seniors and people with disabilities who find repeated shocks painful or startling.

At a Glance

• 1 - Wooden floors and cotton rugs build up less static than synthetic carpet.
• 2 - A small chain fixed to a wheelchair frame and brushing the floor can drain static charge.
• 3 - Shocks are usually only felt once the body is charged to thousands of volts and touches something conductive.
• 4 - The biggest danger from a static shock is usually not the shock itself but a sudden reflex movement that causes an injury.

Electrostatic Discharge

Electrostatic discharge, often called a static shock, is the sudden flow of electricity between two objects with different electrical charges, such as a charged person and a metal door handle. The charge builds up when materials rub together and electrons move from one to the other, especially in dry air, and it is released as a small spark when a conductive path forms. The shock is brief and usually harmless, though it can damage sensitive electronics.

Overview

Did you know a shock from static electricity (technically known as electrostatic discharge, or ESD) is not a true electric shock but rather the pain from a hot spark jumping to or from your finger or other parts of your body? Static electricity is a stationary electric charge that is built up on a material. A common example of static electricity is the electrical shock that we can get when we touch a metallic article. Static electricity is formed when we accumulate extra electrons (negatively-charged particles) and they are discharged to an object or person.

Shuffling your feet across a carpet is a surefire way to generate a painful shock. If the materials can conduct electricity away then the static charges will dissipate, however, if the charges are separated faster than the material can dissipate them, the amount of electrostatic charge builds up.

Static charge build-up is enhanced when the surrounding air is dry, especially when the weather is both cold and dry. When the humidity level is low, static charge will build up, no matter how hard you try to avoid it. Static electricity accumulates because an insulator prevents the accumulated electrons from flowing. That insulator can be your hard soled shoes or excessively dry hands. Some people are more sensitive to these shocks than others. Shocks are usually only felt if your body is charged to over about 4000 Volts, and you touch something conductive like metal objects, water, or other people.

Ways to Prevent Getting Shocked from Static Electricity Discharges:

• Hand cream can increase the conductivity of your skin, preventing a static buildup.
• Touch a less conductive surface first, such as the wall beside the door, or touch the door handle with a key or coin.
• For women wearing clothing with silk linings, or pantyhose, try rubbing a light layer of hand lotion onto your legs before you get dressed.
• If you are getting shocked in bed, try using pajamas or sheets made of different materials. Cotton does not develop as much static electricity as some artificial fibers do.
• People working in areas where ESD can damage sensitive equipment, such as computers and components, often use products designed for static control or elimination, such as grounded wrist straps.
• If the problem is in your house, raising the humidity level tends to help a lot. A home humidifier will also help to decrease static electricity discharges in the house - try and keep the air humidity at or above 30% - though 40% or 50% would be even better.
• A conductive layer of soapy detergent (like from a "bounce" fabric softener pad) sprayed or rubbed across a carpet can prevent the buildup of static from the carpet in your home. Wooden flooring and cotton rugs are the best floor covering for eliminating or reducing shocks.
• Avoid wearing layers of very different fabrics that rub together, such as wool over polyester, since rubbing unlike materials builds up static. Synthetic materials such as polyester are the major culprits, while cotton builds up less charge.
• Supermarket trolleys are notorious for "generating" static electricity due to their insulated wheels. Try carrying a coin, house or car key, with you and touch it to something metal, such as shelves, to discharge any accumulated static electricity before reaching for those cans of food.
• Anti-static straps can be worn around the shoes, which allows static electricity on your body to flow past your insulating hard soled shoes to the floor surface. Wearing leather-soled shoes also helps prevent a build-up of static charge in your body. Other body grounding devices available include; anti-static wrist straps, grounding heel straps and shoes, and conductive feet grounders.
• When you get out of a vehicle, place your hand on the metal part of the door, hold it right above the window on the metal casing while sliding from the car seat. Do not let the door go until your foot touches the ground. You can also purchase an inexpensive metal impregnated rubber strap that attaches to your car and brushes the ground, although there is little evidence that these straps prevent shocks when getting out of the car.

Wheelchairs and Static Electricity Buildup:

As mentioned above, static electricity is generated when objects of dissimilar substances move relative to each other. If one of the objects is non-conductive, such as the rubber wheels on your wheelchair, an electric charge can accumulate and produce sparks. To prevent the generation of the static charges or to drain off charges generated on an object, a conductive path must be ensured. While, (to our knowledge), there are no grounding devices designed specifically for wheelchairs, it should not be a major problem to use a conductive device to achieve grounding. It is imperative, however, that all elements of the wheelchair system be grounded.

You might try using a key or metal rod to touch something else that is metal before you touch it with your hand, or before you touch someone else. Touching the rod to a metal object (not your wheelchair) should drain off the excess charges, allowing you to avoid a shock. It may be inconvenient, but it is one solution. Another solution is to use a small chain fastened to the wheelchair or powerchair frame, allowing the other end to brush the ground or floor.

By taking the proper steps, you can reduce or prevent shocks from a buildup of static electric charges. There is little risk attached to electrostatic discharges, and in most cases they are just a nuisance, the biggest risk is that a sudden unexpected shock could cause you to have an accidental injury. For example, you might pull your arm back suddenly and hit it against something - or someone.

Frequently Asked Questions

Can static electricity harm my health?

Everyday static shocks are brief and very low in energy, so they are not harmful to health, although they can be painful or startling.

Can a static shock damage a power wheelchair?

A strong discharge straight into the controller or other electronics can damage them, so touch a metal object away from the chair first to discharge.

Do dryer sheets stop static on clothes?

Yes. Dryer sheets and liquid fabric softener coat fibers with a thin layer that reduces static cling and shocks.

Is static electricity dangerous at the gas pump?

Static sparks can ignite gasoline vapors in rare cases, so touch the metal of the car before refueling and do not get back into the car while the pump is running.

Do anti-static sprays work on carpets?

Yes. Anti-static sprays leave a film on carpet and upholstery that reduces charge buildup for several weeks and can be reapplied as needed.

Are some people more prone to static shocks?

People with dry skin, those who wear rubber-soled shoes or synthetic clothing, and those who live in dry, heated homes tend to get more shocks.

Can static shocks affect hearing aids or cochlear implants?

Strong static discharges can occasionally disrupt hearing aids or cochlear implant processors, so users are advised to discharge static by touching metal before handling them.

Can pets get static shocks?

Yes. Pets can build up static from carpets and dry air, and lightly dampening your hands before stroking them can help.

Insights, Analysis, and Developments

Editorial Note: Static shocks are almost always harmless, but they matter more for some people than others. A sudden zap can trigger spasms in people with spinal cord injuries or nerve conditions, a discharge straight into a power wheelchair controller can damage its electronics, and static sparks are a known fire risk near gasoline vapors, which is why drivers are advised to touch metal before refueling and not to get back into the car while filling the tank. For most people, a humidifier, regular moisturizer and a change of shoes or clothing fabrics are enough to make frequent shocks a thing of the past.
