Dave Long is the CEO and founder of Staticworx, Inc., a leading provider of flooring solutions for static-free environments. He has 30-plus years of industry experience and combines his comprehensive technical knowledge of electrostatics and concrete substrate testing with a practical understanding of how materials perform in real-world environments.
A fully functional ESD floor prevents static generation and provides an effective path to ground for personnel and equipment. Many conductive and dissipative floors meet STM 7.1 resistance parameters in ANSI/ESD S20.20 but fail to provide adequate electrical contact for grounding equipment with conductive casters and drag chains.
Confusion over ESD flooring resistance terminology and requirements abounds, leaving many in the dark and creating potential risks. This article helps to clarify this complicated issue so that you can work to mitigate the problem.
Controlled environment testing of static control flooring in combination with multiple forms of ESD footwear during the qualification phase can reveal problems and is a mandatory step to avoid installing
non-compliant flooring/footwear systems.
