1. Know the human electrostatic discharge alarm
For the chemical industry, many norms and standards have specific requirements for human electrostatic discharge alarms. They are referred to differently by each specification, including but not limited to the following names:
Human body static discharge (alarm) instrument, electrostatic release column, grounding metal rod, (explosion-proof) static eliminator, human body static elimination device, (explosion-proof type) elimination of human body static electricity facilities, human body static conduction device, (explosion-proof type) static elimination device, (intrinsically safe type) human body static eliminator, human body static release ball.
The human electrostatic discharge (alarm) instrument is mainly composed of touch body, support body, indicator light, buzzer or voice horn, prompt sign and grounding wire, etc., and the touch body is made of sub-conductor material, which can ensure that the static electricity is eliminated quickly and will not produce sparksIt is suitable for petroleum and petrochemical, metallurgy, military industry, oil field, railway, mine, gas production, fireworks, computer room, electrical and electronic and other potential ignition risks and flammable and explosive places.
Second, the common form of human electrostatic discharge alarm
Human Static Electricity - Standard Specification.
SYT 7354-2017 "Safety Specification for Intrinsically Safe Human Static Eliminators".
4.1. Intrinsically safe human body static eliminators should be installed in oil and gas gathering, transportation, treatment or purification, refining, storage, transportation, loading and unloading, refueling and gas, etc.
Q SY1431-2011 "Technical Specification for Anti-static Safety".
3.2.16. Gas stations should meet the following anti-static requirements:
k) The meterer should discharge the static electricity of the human body when he gets on the car for measurement.
o) Before refueling at the self-service dispenser. Refueling personnel must vent human static electricity.
3.3. Technical requirements for anti-static of petrochemical powders.
c) An intrinsically safe human body static eliminator should be set up near the discharge pipe.
3.5.2. The operator should wear anti-static work clothes and anti-static work shoes, and the human body should be discharged electrostatic before operation. Human Static Discharge SYT 7354-2017 "Safety Specification for Intrinsically Safe Human Static Eliminators".
