Difference between Electrical Hazard (EH) vs. Electro Static Dissipative (ESD) Safety Footwear.

(EH) Electrical Hazard Safety Footwear
Electrical Hazard boots and shoes are designed to significantly reduce the flow of electricity that goes through the shoes and ground, which will, in turn, minimize the possibility of getting electrocuted. Electrical Hazard boots will always have an “EH” on the certified label, which is sewn into the inside of the boots.
Electrical Hazard boots are not meant to be the main source of protection in an electrical hazard environment. EH boots are designed to be used as a secondary source of protection. Soft-toe shoes and boots cannot be used as EH rated footwear.
(ESD) Electro Static Dissipating Safety Footwear
Static Dissipating safety shoes (and Static Dissipating soft-toe shoes) are designed to minimize the amount of static electricity build-up on your body. Although EH rated shoes must be safety shoes, Static Dissipating shoes can be either safety or non-safety. Static Dissipating shoes help protect against the dangers of static buildup in the workplace.
ESD shoes are designed to conduct static electricity through the insole, linings, cement, outsole, and into the ground, helping regulate the buildup of electrical charge on a person’s body
