Human electrostatic discharge alarms are divided into ordinary type and explosion-proof type, and there is no unified national standard for the time being. Different industries have clear regulations and requirements for human electrostatic dischargers, and when there are anti-static requirements in non-flammable and explosive hazardous places, you can choose "ordinary electrostatic dischargers".Intrinsically safe human body static eliminators or explosion-proof electrostatic dischargers should be installed in flammable and explosive hazardous places.
