Static Electricity
Static electricity is defined as an imbalance of electric charges within or on the surface of a material. The charge that is created remains stationary (static) until there is an electrical continuity (flow) or an electrical discharge (spark).

Electrostatic Discharge (ESD)
Currents of such a short self-limiting duration are rarely dangerous to humans. On the other hand, special care is needed when handling sensitive electronic devices or when managing flammable materials (due to the risk of a spark being created, leading to ignition).

Electrostatic Discharge (ESD) Floors
One way to eliminate the above phenomenon is the use of antistatic or conductive floors, along with the appropriate equipment, such as antistatic clothing, wrist straps, gloves, shoes, and others. Finally, movement on these floors with the proper equipment should not generate voltages greater than 100 V.

Checking of Antistatic Floors
In order to ensure the suitability and proper functioning of these specific floors, the following two checks are required. The first check concerns the measurement of the electrical resistance of the floor (R2, R3) according to the standards:
- EN 1081:2018 ‘Resilient, laminate and modular multilayer floor coverings – Determination of the electrical resistance
- EN 61340-4-1:2004 ‘Electrostatics – Part 4-1: Standard test methods for specific applications – Electrical resistance of floor coverings and installed floors’
The second check concerns the measurement of charge generation during a specific movement within the space, according to the standard:
- EN 61340-4-5:2018 ‘Electrostatics – Part 4-5: Standard test methods for specific applications – Methods for characterizing the electrostatic protection of footwear and flooring in combination with a person’
