Human body static electricity eliminator
Thread Content
1. As stipulated in“(HG20571-1995) 3.2.10: In workplaces where static electricity hazards may occur, personal anti-static protective equipment should be provided. How should the phrase “At the entrances of areas where fire and explosion prevention measures are crucial, devices for removing static electricity from the human body should be installed” be understood? 2. The security department requires us to install human body static electricity eliminators at the entrances to the ladders on the production equipment. Is this necessary?
Designed as required. Does this issue seem to overlap with the entrance settings? It’s better to have an extra layer of protection. People are used to holding onto handrails; I’ve seen cases where stainless steel is used at the beginning of ladders, connected to ground to eliminate static electricity

Gas leaks can occur suddenly at times; it doesn’t mean that since there are no leaks most of the time, there’s no need for precautions. In fact, such safety devices are meant to handle emergencies. For example, replacing fire extinguishers every two years or annually seems like a waste to me – as long as the substance stored in the tanks poses a risk of explosion by leaking into the atmosphere, such devices are necessary.
Which standard and which clause specifies it clearly? I checked several standards; there are clear regulations for tank areas and storage areas, but no explicit requirements were found for production facilities. Looking forward to your advice
I checked online, and it seems that people say it’s better to have it than not; there are no specific regulations, which is confusing
1. As the name implies, in places where static electricity may pose a risk to production safety, static eliminators must be installed. 2. If there are multiple channels, it is recommended to install an electrostatic dissipator for each one.
There are clear regulations requiring the installation of such systems in tank areas and storage areas, but no specific standards have been found for installing them in production facilities! ! ! ! ! ! ! ! !
Code for Design of Static Grounding in Petrochemical Industries (SH3097-2000) 4.2.5 The hazards caused by electric charge on the human body are increasingly common. It is necessary to discharge static electricity from the human body by touching a grounded surface before entering the tank. A separate metal rod can be used as a grounding element at the inlet end of the tank; it is placed horizontally at the entrance to prevent people from entering the tank. One must push aside this metal rod in order to discharge electricity before being able to enter the tank, and its installation is rather complicated. Another approach is to use a section of escalator (about 1m long) that is not coated with anti-corrosion paint, for human body discharge
Human body static electricity eliminators should be installed at the entrances to the equipment ladders of production facilities. A specific analysis is required
