Abstract. This document cove
2、rs one type of conductive shoes in the designs specified herein. Conductive shoes are intended to be worn by personnel in ordnance or ammunition plants, or other places where the accumulation of static electricity in the body of the wearer constitutes a hazard because of the possibility of its sudde
3、n discharge in the form of a spark that may ignite sensitive explosives, gas mixtures or flammable vapors. The effectiveness of the shoes is dependent on a low-resistance conductive path, sufficiently conductive floors, and on the use of cotton socks or stockings that are sufficiently conductive whe
