Default Don't solder and smoke

I once picked up my cigar, thinking it was my soldering pencil, and tried to put it on the circuit board - well it was 3:00 a.m.!

Then again, there is the oft repeated story of the EE who couldn't figure why his DVM wasn't giving any readings at 3:00 a.m. - he had the probes on the schematic!

That proves 3am is a bad time for electronics work.

The fumes are the worst, but if you are soldering, you should not eat or drink, thats the way you get the lead inside. Drink milk, this is usual for workers that come into contact with a lot of lead. Don't know if it helps, but it won't hurt either.

On the other hand, you would need a mask that has not a particle filter, but also a neutralising action on the fumes. So it won't be a simple affair.

Exclamation Please learn from what happened to me!!!!

Here's what happened to me - please take note!!!!

I've been repairing stuff for ~25 years...

When I was young, my friends always used to joke about my work area having a smoke layer in the air from the flux... They used to think it was funny because the smoke was so thick that it looked like I was getting stoned in there...

Anyway, fast forward ~ 20 years and I was dealing with some heath issues that led to me having some detailed blood work done. The results came back and I had highly ELEVATED ARSENIC LEVELS!!!

At first I couldn't figure out where in world this had come from. Then after much research we tied it to breathing the flux smoke for so many years... As it turned out, the flux was loaded with arsenic! Had to take a bunch of stuff that literally chelated (pulled) it out of my system to get the blood levels down...

So, the lesson learned for me is always to have decent ventilation when working... Did I die from it? No. But who knows the effects that the exposure will have down the road...

Anyway, please learn from my mistakes!!!

Best to each of you,

Question Arsenic?

Hi Apogee,
Does the solder contain Arsenic?

To me it sounds more like someone was putting ratpoison in your food.
Anyway thanks for the warning!

The solder is not the issue...

The arsenic is in the flux...

Research it... the stuff is nasty but sure works well!!!

No rat poison here (although she does have designs on my shop space so I wonder????)

Haha, the longest URL I have ever seen! That won't work. The Conradpartnumber is 817546. Price is Euro 69. I am considering buying it with my next order. It sucks a 165m^3 per hour! The active carbon filter adsorbs the vapors.
You will find Conrad here:
www.conrad.com
I went the cheap way and I'm using regular fan. I just added PS and have very convenient fumes extractor.
Just place it on a bench, beside your work area and your environment is much cleaner. I also use it when putting boards together and anytime I do much soldering. Highly recommended.

Everything I've seen so far (except moving outside to solder) recirculates the air into the same room.

A slightly more expensive option is to pick up a bathroom exhaust fan and mount it on a 5-sided plywood box (made with scrap) with the box opening facing your work area. Connect the exhaust with some flexible dryer-vent tubing out through a window. Home Depot has a model that sells for less than $13 in my neighborhood. Total DIY exhaust hood project cost: less than $25.

Sorry, no pictures.

About the filter, it is recommended that you use a special HEPA filter.

Hi kropf,
Not correct, the Active Carbon filter cleans the air and adsorbs the fumes, airosol and dangerous compunds.
