"If flooring Is used for grounding personnel that handle ESDS [ESD sensitive items] refer to the system requirements In Table 2.[Person/footwear/flooring system Rg < 3,5 x 10E7 ohms OR
Rg < 1.0 x 10E9 ohms and body voltage < 100 V]" [EN 61340-5-1 Edition 1.0 2007-08 EPA requirements Table 3 Notes 4 & 5]

"The use of floor materials to control personnel or equipment generated static has a number of benefits. Floor materials tend to be passive. Employees who work in areas protected with floor
materials simply need to wear and test the appropriate footwear. They do not need to implement any additional actions themselves to assure that the floor material is functioning properly.

Floor materials, particularly floor coverings, finishes, and coatings, can be applied or installed throughout the work environment providing a broad area of control rather than isolated control at individual workstations. They improve the mobility of personnel who work in the environment. Finally, floor materials can help control static on trolleys or other mobile equipment if properly grounded."
