Selecting the right kind of ESD (electrostatic discharge) flooring is always a challenge, and in controlled environments, the stakes are particularly high. While cleanroom environments are known for the exacting standards used to control contaminants, it's ironic that their anti-static flooring doesn't always meet industry specifications. This is a critical concern on several levels:

A cleanroom is a controlled environment where products are manufactured. It is a room in which the concentration of airborne particles is controlled to specified limits.
Ecotile’s MD, James Gedye, explains the proposed ISO Standards for Cleanrooms and how Ecotile’s Industrial and ESD Flooring can provide your organisations’ with a simple and reliable solution that fully supports your Cleanroom requirements.
Eliminating sub-micron airborne contamination is really a process of control. These contaminants are generated by people, process, facilities and equipment and must be continually removed from the air. The level to which these particles need to be removed depends greatly upon the standards required for each organisation.
Static control in packaging has been around for centuries. In its earliest years, it was used to prevent the electrostatic discharge (ESD) ignition of gunpowder stores. Today, there are many kinds of devices, parts, and pieces manufactured in cleanrooms that are vulnerable to ESD. Since basic motion and activity can create a static charge, it’s important that these items are packaged in ESD protective materials. Here are a few options.
MANY FACILITY PLANNERS, concerned about contamination or potential scheduling delays, once dismissed the thought of installing electrostatic discharge (ESD) safe tile in operational clean spaces. Rather than risk tearing their buildings apart and losing valuable production time, many companies chose alternative methods to ESD flooring to be ANSI/ESD S20.20-1999 compliant. ESD industry control practices may include the combination of wrist straps, grounding cords, floor mats and “Faraday Cage” material handling protocols. Until recently, installing a new ESD floor most often included the difficult taskof removing the old floor first.
Let us start with the reasons why a functioning cleanroom facility manager might want or need to replace a floor. Regardless of the issues involved, one does not replace an existing floor unless it is absolutely necessary. Floors are only replaced when the existing flooring, usually a seamless epoxy or tile, becomes incompatible with ongoing needs. In a cleanroom or cleanmanufacturing facility, there are four main reasons why this happens:
In any of the four replacement scenarios above, before any serious plans are made or dismissed, it makes sense to start with a broad evaluation of various ESD flooring alternatives. Any thoughtful evaluation should begin with an investigation involving process compatibility, and then an examination of the risks/rewards of installing a new floor based on successfully dealing with obstacles such as shutdowns, equipment movement, loss of production, contamination, odor containment and other considerations. At this point it is usually advisable to create a decision matrix or at least give a cursory glance at ESD flooring solutions. Of course most of the options will be quickly dismissed based on contamination control parameters or unsatisfactory electrical properties (point to point resistance, and resistance to a groundable point).Below is a reasonable list of possible flooring materials:
