DS/ET-PSA Human Static Discharge Alarm Reference Standard

DS/The design of ET-PSA human static discharge alarm refers to the following national standards:
GB12158-2006 "General Guidelines for Preventing Static Electricity Accidents"
Article 14.3.13 stipulates that due to the widespread use of artificial fabric clothing, artificial fabrics are prone to static electricity, which often accumulates in people

On the body. To prevent sparks that may be generated by static electricity, it is necessary to inspect the operating platforms that enter the light oil pump room, the top of the light oil tank, and the light oil operation area

Install devices to eliminate human static electricity on escalators or at entrances in explosive hazardous areas. This static elimination device refers to a device made of metal tubes

The handrail should be touched by the human body to eliminate static electricity before entering these places.
SH3097-2000 "Design Specification for Static Electricity Grounding in Petrochemical Industry"
The ET-PSA human static discharge alarm has been certified by the National Center for Quality Supervision and Inspection of Explosion proof Electrical Products (NCEX) and meets the following standards:
GB3836.1-2010 Explosive Atmosphere Part 1: General Requirements for Equipment
GB3836.4-2010 Explosive Atmosphere Part 4: Equipment Protected by Intrinsic Safety Type "i"
