Q: Is it ok to wear ESD shoes or heel, toe, or sole grounders outside?
A: No. MIL-HDBK-263B Appendix 1 page 101 40.1.2 states, “Conductive shoes, shoe covers, or heel grounders should be used to discharge personnel on conductive floors. These items should only be worn in the ESD protected areas and should be kept clean so that contaminants do not inhibit their conductive interface with the floor.”
To be certain that you are not compromising the effectiveness of your ESD personal equipment you should not wear them outside the EPA (ESD Protected Environment). Simply don them before going into the EPA and take them off when you leave. This also serves to protect your investment and to maintain its longevity.
It is also very important to keep them clean (vacuum inside of shoes weekly and maybe clean out-soles and grounders with soapy water once a week) and you’ll get more wear out of them in addition to maintaining their effectiveness.
