Today we have with us Karry Johnson, our US National Sales Manager to tell us about the difference between Electro Static Dissipating footwear and Electrical Hazard protecting footwear.
The difference between Electro Static Dissipating (ESD) footwear and Electrical Hazard (EH) can be confusing! Both deal with what seems to be similar things, when in fact they are quite different. To help you be as safe as you can be in your working environment, let’s go over the differences.
We’ll start with ESD. The human body behaves as a walking isolated conductor of electricity. When you walk, you body generates a static charge. (Think about those times as a kid when you would rub your socks on the carpet to try to shock your friend.) So when you work in a technical environment, such as a factory where you are making electric chips, you don’t want to give off the static electricity generated by your own body because it could zap the chips, making them useless. Wearing Cat’s ESD boots, like the Elkhart or Gunnison, will minimize the charge that your body creates.
EH boots, on the other hand, are designed to significantly reduce the flow of electricity through your body. EH boots like the Alaska or Silverton are ideal for when you are working with live electrical circuits or wires. EH boots will help to stop the electricity from the wires from zapping you; instead they slow the electricity down as it comes to and goes through your body. Cat Electrical Hazard footwear is rated ASTM F2413-05 1/75 EH and will protect the wearer in open circuits up to 14,000 volts in dry conditions.
Hopefully these descriptions provide a little bit more understanding and can help you in finding the best pair of shoes or boots for your job! Thanks to Karry for taking the time to explain the difference to us!
