I worked in a micro-electronics lab testing micro-chip assemblies.We were required to wear a daily tested(and documented) wrist strap that was hooked up to the ESD bench mat,floor mat whenever we were handling/touching/testing the ESD assemblies or the micro chips.
The policy and procedures were generated by the Q.A.dept.
Whenever we left our work stations we "un-hooked" our wrist straps,but before we went back to work we were required to test them while we were connected.The test was measuring the strap connection to the skin.
