4.7 Grounding Equipment and 
Methods
Grounding equipment must include either a wrist strap or a foot 
strap at a grounded workstation.
■ When seated, wear a wrist strap connected to a grounded 
system. Wrist straps are flexible straps with a minimum of 
one megohm ±10% resistance in the ground cords. To 
provide proper ground, wear a strap snugly against the skin 
at all times. On grounded mats with banana-plug connectors, 
connect a wrist strap with alligator clips.
■ When standing, use foot straps and a grounded floor mat. 
Foot straps (heel, toe, or boot straps) can be used at standing 
workstations and are compatible with most types of shoes 
or boots. On conductive floors or dissipative floor mats, use 
foot straps on both feet with a minimum of one-megohm 
resistance between the operator and ground. To be effective, 
the conductive strips must be worn in contact with the skin.
