Cleaning
Foot grounders are to ground static charges, while
dirt generally provides an insulative layer adversely
effecting reliability. For proper operation, the Foot
Grounder and its conductive strip must be kept
clean.
The rubber portion of the Foot Grounder should
be cleaned using Desco’s Reztore™ Antistatic
Surface & Mat Cleaner or “Static-Wipes” wipers.
An alternative would be to clean using isopropyl
alcohol. The Desco cleaning products are specially
formulated for cleaning ESD control components
and are silicone free. This is critical as silicone is an
insulator. Desco ESD cleaners should not be used to
clean the nylon polyester grounding tab.
Foot Grounders can be safely hand or machine
washed on gentle cycle. Mild detergents, such as
Woolite® or a liquid dish washing product and warm
water are recommended. However, care must be
taken to ensure that these detergents are silicone
free.

HEEL GROUNDERS
Desco model 07560, 17200, 17202, 17250, 17252,
and 17260 heel grounders are designed for use on
standard shoes. All Desco foot grounders can be
easily adjusted to fit the individual wearer. Desco
heel grounders have a dissipative lining that will not
mar white or light colored shoes. Models 07560,
17200, 17202, and 17252 have a current limiting one
or two megohm resistor in series with the grounding
tab. Models 17250 and have no resistor.
These foot grounders include
a molded external resistor
and a permanently
attached grounding tab.
1. Place foot
grounder on the shoe
so that the blue lining
is making contact
with the shoe.
2. Insert the grounding
tab inside
of the shoe and under
the foot. Make sure
that a solid contact
is made between
the sock and body.
Cut grounding tab
to desired length.
3. Pull
the strap
through the D-ring and
clinch down for a snug,
comfortable fit.
4. Test each foot
grounder to confirm
proper installation.
HEEL GROUNDER WITH SNAP-LOC
FASTENING SYSTEM
The Desco model 07515 heel grounders
are equipped with a Snap-Loc quick release
fastening system. The model 07515 has a cup
and lining that will not mar shoes or floors. The
07515 has a molded exterior 2 megohm resistor.

Foot Grounders - Grounding,
Testing, and Maintenance
Description
Desco’s complete line of foot grounders has been
created to provide a continuous ground path
between the operator and a properly grounded
ESD protected flooring. Foot grounders are
designed for use in applications where user mobility
is required, such as wave solder, kitting, and quality
control. Per ANSI/ESD S20.20 Paragraph 6.2.2.2,
“ESD protective flooring used with approved
footwear, may be used as an alternative to the
wrist strap system for standing operations.” Foot
grounders quickly and effectively drain the static
charges which collect on personnel during normal,
everyday activities.
General Guidelines
1. It is recommended that foot grounders be worn
on both feet, in order to assure that a continuous
path to ground is maintained.
2. Grounding tabs should be tucked inside the
shoe with as much contact area as possible to
the bottom of the stockinged foot. Foot grounders
rely upon the perspiration in the shoe to sustain
electrical contact between the conductive grounding
tab and the body.
3. Foot grounders should be used in conjunction
with floor surfaces which have a surface resistance
of less than 1 x 10E9 ohms.
4. A current limiting one or two megohm resistor in
series with the grounding tab is recommended.
Testing Your Foot Grounders
The best test of your foot grounder is one that
includes all three components: the individual foot
grounder, the grounding tab and the interface
between the grounding tab and the wearer’s
sweatlayer.
Desco has testers designed to properly test foot
grounders. For more detailed information on these
testers, ask for technical bulletins TB-2040 (19252,
19253).
If you obtain a fail reading from the tester you
should stop working and clean the foot ground and
grounding tab. Retest after cleaning. If the unit still
fails, replace the foot grounder. Retest the system
before beginning work.

D-RING HEEL GROUNDERS
Desco model 07590 heel grounders are equipped
with an elastic D-ring fastening system which
provides snug cinching of the ankle strap and allows
“flex” during walking. They are designed for use on
most types of shoes and boots. The light blue lining
prevents marring on white or light colored shoes.
1. Place the foot grounder on
the shoe so that the lining is
making contact with the
shoe.
2. Insert the grounding
tab inside of the shoe
and under the foot.
Make sure that a solid contact
is made between the sock and
body. Cut grounding tab to
desired length.
3. Fasten hook and loop
straps together, securing
foot grounder firmly on
shoe.
4. Test each foot
grounder to confirm
proper installation.
