“While a person may be grounded using a wrist strap or

other grounding methods, that does not mean that insulative

clothing fabrics can dissipate a charge to that person’s

skin and then to ground. Personnel clothing usually is

electrically separate or isolated from the body.” “Groundable

conductive nylon fibers are woven in a chain-link design

throughout the material, providing continuous and consistent

panel and from sleeve to sleeve in accordance with the ESD

Association Garment Standard, ESD-STM2.1.

“After verifying that the garment has electrical conductivity

through all panels, the garment should be electrically

bonded to the grounding system of the wearer so as not to

act as a floating conductor.” [ESD TR20.20-2008 section

5.3.13 Garments] The conductive fabric in smock is a

conductor. If not grounded, the smock can become an

isolated charged conductor. If not grounded via a wrist strap

coil cord, ground the ESD garment using ESD footwear to

ESD flooring.

The dissipative material becomes part of the ground path

in two lengths -- the lab coat length and the jacket length.

Both lengths are available in two styles - with snaps and

with conductive elastic cuffs. Smocks are available in eight

colors* -- blue, white, teal, burgundy, black, camouflage,

pink and grey.

feature which allows for hands-free grounding with no

cord attached to the operator’s wrist. This feature allows

connection of a ground cord to a 4mm snap stud on the hip.

A seam of carbon-suffused threads provides a secure and

direct electrical connection from the snap stud on the hip

person when used in this manner. Standard touch testing or

continuous monitoring can be used to test the “hip-to-cuff”

function.
