Eliminate Static Electrification in Workplace: Anti-Static Mats & Solutions for Packing Tables

Hello.
in the company we have a problem with electrification which is transferred from parcels packed by people on their own. after packing a few packages and touching the metal frame of the packing table, quite strong discharges occur. You cannot use cable ties too much because the hands of the proactors must be unrestrained.

Do you have any other ideas not hindering hand movements?

e.g. anti-static mats or other inventions.

thanks for your help in advance
greetings

Hey, see "antistatic" at www.tme.pl
or maybe air humidification?

Hi.

Unfortunately, air humidification is not an option due to the nature of production (tea) and the size of the hall. The air is dry, that's true, but there's nothing you can do about it.

But thanks for the hint :)

greetings

After all, the earthing does not need to be on hand. You can put grounded handcuffs on, for example, a leg. The certainty (stability) of the contact is important. An additional advantage - they will not be able to leave the post without permission. On the other hand, I do not recommend a loose "mat under the ass" type, because after a temporary lack of contact the effect can be achieved thundering .

Hello.

Have you ever met something like wristbands without wires, for example with resistors discharging the accumulated charges? that would be the perfect solution :)

greetings

And where would they take these loads?

Perhaps, at best, something that would be a wristband, and a "wire" with high resistance hangs from it
- so that touching it to something grounded does not give a noticeable discharge, but that
caused the cargo to float away in a fraction of a second; the capacity of the human body is of the order
1nF, static voltage a few kV, so a charge of a few uC - a current of the milliampere will discharge it within
milliseconds, and will not be perceptible. Only when someone touches the grounded table frame with his hand so that
does not touch this "wire" before, it will not avoid discharging despite such a device ...

Perhaps it is better to pay attention to the floor, and to the footwear - there are special antistatic shoes, used
eg by employees of telephone exchanges - there, too, the static was annoying.
Question: Are ordinary rubber soled (black rubber) sandals antistatic?

And is it theoretically possible that the charges on the wristband were neutralized by the resistors mounted on it?

I think something like this would work, but is it?
Then the charges would be released in the form of heat, but only if the current would flow through the resistors if the potential was obtained :)

a seemingly banal subject, but only seemingly

Unfortunately, the charge retention law applies - so far no exceptions have been detected,
and changing the load into heat or heat into a load (it would also be useful) has no chance ...

As the previous speakers say, if you do not want bands and cables, it is only a suitable substrate and protective clothing. Read what antistatic protections are used in factories of electronic parts and assemblies. The floors are very expensive and so are the clothes.

And is there any way to neutralize or discharge them apart from the flow of charges to ground? These are electrons? :)

greetings

chyab, the only known methods are good (effective) earth electrode. For example, in flextronics, the floor is made of special materials, employees use appropriate clothing, including bands, and the more endangered areas are entered through gates that check the load of the bodies and if the standard is exceeded, you must first discharge. It is no wonder that the production of high-class electronics forces us to make such moves. In your production, I would try to put some sheets on the ground, e.g. aluminum, and connect them to the ground, and maybe shoes with some conductive carbon rubber. when it works, you already know what to do.

Welcome,
There is quite a lot of materials on ESD - one thing is certain, to properly protect electronic components (or other components sensitive to electrostatic discharges), you should use bands (for shoes, hands) and here it is important - that these bands have built-in resistors with a value of 1Mohm, I think you know why.
In our company (Lacroix Electronics) http://www.sofrel-ems.com/
it is very much respected

Below is one of the websites offering such security.
