Hi!

I'm wondering if the Arduino Uno, Chinese NodeMCU Wifi Arduino compatible board or any Chinese Arduino modules like the L298N contains any flame retardants? And if so, are they toxic like BFRs?

With so many clones and different manufacturers it would have to be on a case by case basis.

Is it common that the Chinese manufactures add flame retardants?

Why don't you ask the Chinese manufacturers?

Why are you interested if its 'common' ?

Hi!
A newbie question.
I absolutely LOVE Arduino! I own a few Arduinos, both real and Chinese editions. But I feel worried about the flame retardants. If I touch a circuit board, like an Arduino or Arduino module, then touch my desk, computer mouse and keyboard, does the flame retardants also get stuck on the stuff I touch with my hands? Later when I'm working on my computer and eating a sandwich, will the flame retardants go from my computer or desk to the sandwich and then get inside my body???  :smiley-eek-blue:
How dangerous is that? Can I get cancer of it? Am I living in flame retardants?

Why start a new topic?

At least you won't spontaneously combust :D

My last topic was about flame retardants in electronics. This more one is about health. Just wanted a more relevant title...

FR-4 pcb material is used in the majority of all electronics in the planet.  https://en.wikipedia.org/wiki/FR-4

You are probably thinking the bromine compound in it can be spread by contact as with spray-on flame retardant, but its not sprayed on, its integral with the fibre-glass resin and thus fixed in place.

Maybe because this is a forum, and he's asking the forum members if they have any knowledge/experience with this matter. It is simpler than having discourse with a Chinese manufacturer (believe me, I've tried)!

Keep the dust levels down by regularly vacuuming your work area; and use a HEPA filter in the vaccum cleaner.
 
Always wash your hands before you eat anything.
Wash your hands before you touch yourself, or before putting your fingers in your mouth or ears etc.
Maybe consider putting a newspaper down on the desk top and change it regularly.
Wear gloves if you can.
Wash your hands after working at the desktop.
Avoid touching anything as you go to wash your hands or gloves.
Also consider wearing a face mask to avoid inhaling contaminated dust particles.

Most of the things in your home have flame retardants (sofas, bedding etc), so be careful near those things.

You are your own health officer.

Stay safe out there.

Hi,
If harmful flame retardants were used in Arduino components, there would be less of us around to answer your question.

What makes you think that flame retardant chemicals are use and not just non-flammable materials.

If you think that the PCBs are covered in flame retardant, why are you not afraid to go outside where the proliferation of retardants would be a higher risk. Cars, trains, buses, buildings.

Sorry but I think you are over-thinking the situation.
