Static charge occurs when two surfaces with different resistance to electric current come in contact and are then separated. It can be generated by something as simple as walking across a floor. In most cases, a person would not perceive the charge, because it takes about 3,500 volts for a person to feel any sensation from static shock. However, it can take as little as 25 volts to damage sensitive equipment.
Controlling Electrostatic Discharge with Static-Resistant Floor Coatings
Charge can be transferred as personnel interact with a variety of equipment and machinery and products. As flooring is the single common element that both personnel and every item in any environment encounter, applying electrostatic dissipative (ESD) coatings are the best preventative measure you can take.
An Electrostatic Dissipative (ESD) vs. Conductive Coating – What’s the Difference?
Every material has a level of resistance to electricity, measured in ohms. The higher the resistance, the less conductive it is. For example, most metals have a resistance of near zero (0) ohms, whereas wood can have a resistance of a billion or more ohms.
Per the ESD/EOS Association, conductive flooring is defined as flooring with a resistance up to 1 million ohms, and dissipative flooring has a resistance of 1 million to 1 billion ohms. Identifying the range of resistance needed in your facility is a key factor in determining the system and products you need.
