What is ESD?
ESD (Electrostatic Discharge) is static electricity that is transferred from one object to another. We daily experience ESD as an electric shock or a spark, such as when we walk on a carpet or get out of a car and then touch something made of metal.
Static electricity occurs when non-conducting materials such as a shoe sole and floor surface touch one another. How much static electricity is stored in your body depends on materials, clothing, weather and indoor climate, but it reaches its highest level when humidity is low. For instance, we experience this on a frosty day when the hair stands up and becomes charged with static electricity, or if we feel a tiny electric shock when touching metal.
You can minimise static electricity using conductive materials, such as ESD approved footwear or clothing that literally grounds you and conducts static electricity away from your body. This way, you avoid transferring the static electricity to the material you are working with.
How much static electricity do you generate?
| 10-20% relative humidity | 65-90% relative humidity | |
|---|---|---|
| Person walking on a synthetic carpet | 35.000 Volts | 1.500 Volts |
| Person walking on vinyl flooring | 12.000 Volts | 250 Volts |
| Person in a seated workplace | 6.000 Volts | 100 Volts |
| PVC bag lifted from a table top | 20.000 Volts | 1.200 Volts |
| Desk chair with a polyurethane seat | 18.000 Volts | 1.500 Volts |
The lower the humidity, the more static electricity you will generate
Why protect against ESD?
Electronic components are very sensitive to static electricity and are affected by voltages that are far below what we daily experience as small shocks.
For instance, a sedentary person can generate up to 6,000 volts and first notice static electricity at 3,000 volts. But sensitive electronics can be damaged at just 100 volts. ESD protection is therefore important for all businesses working with electronic components – and especially for all internal employees and external craftspeople, installers and others working in ESD-critical areas (EPA – Electrostatic Discharge Protected Area).
What are the consequences of ESD?
ESD can cause severe damage to electronic components. The damage can occur during production, assembly, repair and servicing. In 10% of cases the damages are discovered internally, which may result in the loss of valuable time, reduced efficiency and increased production costs. But in 90% of cases the damage will only appear later – in the form of reduced performance, a periodic bug or a broken product.
It can do great damage to your company's image and lead to:
- Lost sales
- Decreased customer satisfaction and negative publicity
- Increased service-related costs and repairs
Choice of work footwear
When choosing work footwear for your customers, your employees or yourself, be aware of the difference between antistatic footwear and ESD approved footwear.
Antistatic footwear
Antistatic footwear dissipates the static electricity but has a relatively low conductivity. The user will therefore accumulate a larger amount of static electricity in the body. The electrical resistance is between 0.1 MΩ and 1000 MΩ, which is far above the standards for ESD approved footwear.
ESD approved footwear
ESD approved footwear ensures a continuous discharge of static electricity. The conductivity is significantly higher than in antistatic footwear, so the user absorbs a minimal amount of static electricity. In accordance with standards, the electrical resistance must be between 0.1 MΩ and 100 MΩ (EN 61340-4-3) or 0.1 MΩ and 35 MΩ (EN 61340-5-1). ESD approved footwear is always marked with the yellow ESD symbol.
More and more companies are requiring that employees use ESD approved work footwear. And although the challenges are greatest in the electronics industry, the use of ESD approved footwear is becoming more and more widespread in transportation and warehousing, and construction and craftsmanship.
