EH or ESD? What's the Difference?

(EH) Electrical Hazard Safety Footwear

Electric Hazard shoes are designed to impede the flow of electricity through the shoe and to ground, thereby reducing the possibly of electrocution (ASTM F2413-05 Sec. 7.1.5.2).  

It’s worth mentioning that electrical hazard shoes are not designed to be the primary source of protection in an electrical hazard environment. They are designed to be a secondary source of protection in an electrical hazard environment. (ASTM F2413-05 Sec. 5.5.4 & Sec 5.5.2),

 

 

(SD) Static Dissipating Safety and non-Safety Footwear

Static Dissipating safety shoes are designed to minimize the amount of static electricity build up on your body. Static dissipating shoes help protect against the dangers of static buildup in the workplace. ESD shoes conduct static electricity through the insole, linings, outsole and into the ground, helping regulate the buildup of electrical charge on a person’s body.

 

In order for static dissipating shoes to work correctly, you’ll need to make sure of the following:

  • Never put in another type of insole into the shoe. Only used the specially designed static dissipating insole, otherwise the static electricity will not flow through the insole.
  • If your insole becomes non-conductive, you should replace the shoes immediately. If you do not, your shoes will not dissipate static electricity.
  • It’s important that the sole of your shoe is always clean. If your sole is dirty with dust and other foreign material, it won’t be able to maintain good contact with the floor. Meaning the static electricity will not be able to flow into the ground.

Static dissipating safety shoes are mainly worn in computer component handling facilities, processing plants, and manufacturing facilities. This is because those particular environments cause a build-up of static electricity on the employees who are operating the machines and if the employee touches metal or another person, they will feel a “shock”. Static Dissipating shoes can prevent this “shock”
