Electrostatic discharge device, eliminating the body static, explosion-proof body static export ball, static eliminator respect human electrostatic discharge report national standards body electrostatic discharge King reported the following national standard reference design: GB12158-2006 "General Guidelines to prevent static electricity accident" GB50074 -2002 "Oil database design specifications" section 14.3.13 states: Because people wearing clothes very common artificial fabrics, synthetic fabric is easy to produce static electricity, tend to accumulate in the human body. To prevent static sparks that may arise, the need for entering the light oil pumping station, light tank top, light oil on the platform work area, as well as explosive or hazardous areas, etc. of the escalator at the entrance to set the device to eliminate static electricity in the human body. This refers to the elimination of static devices made of metal pipe handrails, before entering such places should be touching the handrail body to eliminate body static.
