Technetters, got a question about resistance (or surface resistivity) of static dissipative lab coats.

I've been pushing for people to keep their coats closed here, as suggested by several technetters a few weeks back.

Now one of the operators tells me, Those lab coats don't work, I tried to measure the resistance and they are no good.


So I went to our wrist and heel strap checker and found I could not get my cuff to cuff resistance to pass either wrist or heel check.  It failed high.  When I checked the resistance between snaps on one cuff, using a multimeter, I found 10-20 megohms.  My coat is white with grey threads through it, the conductive nylon filaments, I guess.  It's made from 4 or 5 or more pieces of material, like a lot of coats.  There is a metal rivet in each sholder where 3 pieces of fabric come together, that looks like it's supposed to connect the nylon from the various pieces.

Can anyone comment on my experience?
