Static electricity?

[Mister Woof]

So I noticed today that after typing on my computer (keyboard, have a mat under the keyboard and mouse) while wearing rubber slides on laminated flooring, every time I get up to touch my fridge, I get shocked.

 

I tested without my wearing my rubber slides, and no shock.

 

I tested WITH rubber slides, but touching my PC case prior to touching fridge, no shock.

 

Rubber soled shoes with cloth insoles, no shock.

 

Made me wonder if something's not grounded right.

 

It seems my PC case is, as touching it produced no shock with rubber shoes, but prevents static shock from touching the fridge handle.

 

It seems the fridge is fine, because without rubber shoes or after touching PC case before touching fridge, I get no shock. Or maybe the fridge isn't grounded correctly? Or maybe the handle just isn't.

 

Are my keyboard/mouse not grounded? or are they insulated themselves, so I am only building static electricity between my mousemat/keyboard/chair and since I have rubber shoes, it's just staying with me until I discharge to PC or touch the fridge?

 

Humidity appears to be 44% right now.

That reminds me of this.

Is your fridge made of metal, at least the handle?

 

 

Could be its really not grounded or something. And your PC is, hence no shock.

 

But what it really is, is your rubber "slides" apparently , you ideally shouldnt wear them when handling electronic appliances.

 

Im not saying its dangerous, because  in most cases it isnt, unless you touch a motherboard or something, but simply because its hella annoying lol.

dust? chair?  "Humidity appears to be 44% right now.", grounding or noise?

Not sure, but I do remember old TV's produce such noise were you gain some static charge?

Just have something to discharge it all the time

Metal fridge. The outlet appears to be grounded properly via the tester from when I moved in. And it doesn't normally shock me. Didn't shock my wife either with the same test (but she doesn't have rubber shoes).

 

But yeah I think the rubber slides are it.

 

 

Maybe time to upgrade my slippers to leather.

No more than usual. No noise. I did get new larger deskmats, which is the only difference.

 

Maybe I need to spray them down with some clingfree.

 

Or upgrade my shoes

My first thought is the OP is wearing some clothing made of wool or silk. Radon Fiber will produced Static as well. Shaggy Carpet? 

 

Doesn't Rubber keep folks from getting shocked?

No it keeps you isolated or insulation from electrical flow? so if you are charged, touching something will discharge you and the electricity has to flow somewhere.

Rubber is an insulator, so it prevents you from discharging static into the ground so it stays with you until you touch something that is grounded or conductive 

 

so i think while at my desk in my chair on the computer, with rubber shoes, I just kept accumulating static electricity, and did not discharge until I touched something conductive (fridge handle) or grounded (pc case)

Yeah its probably a combination of a lot of things, the slides, the floor, even those mats.

 

Its funny i wear such slippers as well, but we mostly have wood or stone floor, and i bareley ever get a static discharge ever… the only thing where it happens every time is getting  out of my car and touching its door… every time lol, without "slides" obviously (and its outside the house) 

Are the mats anti static?  Thats another thing i always shake my head when they sell "anti static" mouse mats… sure it maybe anti static, but what it really does is make any discharge go directly into whatever is on the mat, because the electricity has nowhere else to go…  the only way this actually works is when the person using such a mat is *also grounded* otherwise this makes literally no sense, and i doubt most people using these are grounded.  

 

^I used to work in a "ESD" safe section for "surface mounted devices" thats how I know, the whole floor of the department was actually grounded, the wokplaces had "anti static mats" connected to 12v power *and* we had to wear "ESD safe shoes" which basically made contact with the floor to avoid any ESD.

 

So take one or two of those measurements out and you have zero ESD safety.   (yes, i dont know if your mats are anti static, just saying lol)

not sure really, just some cheap mats that are what your typical mouse pad are made from

Wouldn't cardboard work just as well? My Dad does that. I did look straight at the Carpet after he told me that.

I mean my desktop itself is probably better than cardboard.

Very Likely. Well with good cases.
