Device for discharging static electricity
Thread Content
Our company has several explosion-proof areas, and it is well known that static electricity on the human body must be eliminated before entering such areas. Previously, people would touch static discharge devices to do this, but recent inspections by relevant authorities have required a shift from passive to active methods; in other words, anti-static door curtains should be installed at the entrances, so that static electricity is discharged when one lifts the curtain while entering. This approach is certainly good, but it requires additional investment in safety measures. Is this really necessary? Who else has any other good methods and ideas?
The workshop is wondering whether it’s possible to install a horizontal bar at the entrance; people would need to push this bar to get in, and it should return to its original position automatically after they enter or leave. However, they’re not sure how to set up such an automatic returning mechanism, so they hope someone can give them some advice.
It returns to its original position automatically after entering or exiting, but I don’t know how to set up the automatic return mechanism This is easy to handle – don’t set it as a horizontal layout; use a rotating layout instead, so that one person can turn it. Many supermarkets use this type of setup. Is this considered a patent? :lol :victory: Fly across the sea, +3 wealth! Active participation! In the event of an emergency evacuation, how should people evacuate? The lower part of it is designed as a sleeve; in an emergency, by removing this sleeve, the upper partition can be taken down, allowing for the rapid evacuation of people.

Install spring hinges; it’s the same principle as spring doors. But will this ensure that people have access to it?
Even with an electrostatic door curtain, it’s not guaranteed that one won’t lift the curtain with their hand; it remains quite difficult to achieve active control...
The essence is correct; the form can vary, such as a long guardrail at the entrance. Appropriate devices installed along the path leading to the entrance can achieve good results through signs and other warnings.
I’ve seen some companies install protective barriers at certain sections at the entrance; people walk under these barriers when entering, and the barriers are grounded. Of course, this doesn’t guarantee that people will actually hold onto the barriers. Is there any way to ensure that they do so?
Our company’s approach is quite simple – we just installed an electrostatic dissipator
Any safety measures that employees fail to carry out or simply ignore are useless. The company isn’t a kindergarten; it should focus on educating people rather than relying on solutions that provide permanent protection. Enough static eliminators have been installed; what’s left is to ensure that employees follow the requirements
A sphere (with a diameter of 50 to 150 mm and positioned at a height of about 1.2 to 1.5 meters above the ground) can be installed at the entrance, with an anti-static grounding device connected to it below.
An anti-static door curtain is a good option; if that doesn’t work, just create a puddle – one must walk through it to get through
The key issue is whether employees can carry out their tasks properly; I believe that using static eliminators will suffice to eliminate static electricity, which in turn requires an increased focus on safety training and education.
