Unhappy Will I get sick

I know this would probably be better in a tech forum but I'll try it here since more people frequent here.

I read in the body exterior forum that welding galvanized steel can be really dangerous and make you sick.

I always knew I was dangerous but my friend told me if I have enough ventilation I'll be fine.

So I welded galvanized steel a month ago but I did it outside since I knew I needed ventilation. Nothin' ever happned after that but now I'm kinda scared. Do you guys think that if it woulda affected me I woulda noticed by now?


Mike

You should be ok, the damage is already done. Now if you were diabetic I would say get to the hospital quick, but your only 16, low chance of that.

Dude, I'm only joking. As far as I know it's just hard on your body. Like painting with out a mask or something.

Putting extreme heat (welding) on galvanized metal will produce lead oxide vapors, which are toxic. It's a cumulative effect, and unless you get a huge dose, you won't feel it, but the lead will accumulate in your body and you will get symptoms as you get older. When you are young and invincible this isn't an issue, I suppose.....

The lead will accumulate in your body's fat cells and there is no way to flush it out, so once it's there, it's there forever......

welding

The sure sign that you got to much is you will get flu like symptoms the next day. If you were exposed to alot of fumes the symptoms would be really bad.

Your ok........ but i strongly suggest you don't weld it no more... it does bad things to you body.....

or what I do is slap on thick coats of bondo and then get the grinder out and put a sanding disk on and sand all the bondo down. In short time the bondo is EVERYWHERE in my garage in little dust particles, that bad for the lung to0?

Hey Mike!

Mike, and everybody else too.
Heres some safety info for you.
There are also a couple of links you need to read. Just like it was a school assignment.

Here's the one on Heavy Metal Poisoning. No not the Styx song. well sortof.
and a quote from it:
Quote:
Symptoms will vary, depending on the nature and the quantity of the heavy metal ingested. Patients may complain of nausea, vomiting, diarrhea, stomach pain, headache, sweating, and a metallic taste in the mouth. Depending on the metal, there may be blue-black lines in the gum tissues. In severe cases, patients exhibit obvious impairment of cognitive, motor, and language skills. The expression "mad as a hatter" comes from the mercury poisoning prevalent in 17th century France among hatmakers who soaked animal hides in a solution of mercuric nitrate to soften the hair.
This is a PDF on Welding Galvanized Iron safely
Quote:
The first line of defense in dealing with zinc oxide fumes is welder training. Welders should taught -- even when welding uncoated materials -- to keep their heads out of the fume plume and to position themselves relative to the air flow around themselves so fumes and dust do not collect inside their welding shields. If a welder finds white dust inside his welding shield when welding galvanized products, he is not positioning himself properly. When welding galvanized products that have thin, uniform coatings and the process is gas-shielded MIG or flux core, the gumes generated are sparse and the shielding gas blows them away from the welder; this is frequently sufficient to avoid metal fume fever without further action.
To complement proper positioning, a fully effective method to preventing inhaling zinc fumes is to wear a suitable respirator (mask).

Some of the commercial products which are suitable are:
Manufacturer Product Description Cost ($ each)
3M (800-328-1667) 9920 Half-Mask, Disposable 4.50
3M 9925 Half-Mask, Disposable 5.00
3M 9970 Half-Mask, Disposable 6.50
Moldex 3400 Half-Mask, Disposable 6.00

Here's some stuff you should know.

1. Always wear a dust mask when grinding or sanding. Paint and Resin (Epoxy, Vinyl etc.) materials can cause allergic reactions even if they are labeled "non-toxic. Most of them are toxic. Even completely inert substances, when inhaled as small particles, will damage the lungs.

2. Wear gloves Dust from Bondo type materials cause allergic reactions when in contact with the skin. It affects some people more than others but chemicals from the resins are absorbed through the skin and may cause liver deterioration over time.

3. Safety Glasses! I would hope I wouldn't even have to mention them except if you are working in heavy dust they should be goggles or a ventilated hood.

Isn't there a safety manual on HR somewhere? I swear I've seen this discussed.

I'm pretty up on this stuff because I was able to trade doing a Safety Manual for a place in return for blasting and priming my front clip.

Roy.

When ever you weld galvanized metal you should always position yourself upwind of the work surface and work in an outside well ventilated area. I always use a fan to help blow the smoke away also. Position the fan so it blows at your face and not the weld area, or else it will blow the shielding gas from the work and the work quality will suffer .

Before reading all the technical information that will likely bore you to tears, read what a real person has to say (click here) .

Eric, known as Sevt_Chevelle here on Hotrodders is a great guy, just turned 27 last week (happy birthday Eric) and is damaged for life from ONE exposure to zinc fumes. Weld thru primer, ecoat primer both are very rich in zinc, just like galvanizing.

Like I tell the guys at work when I see them without protection, you aren't always going to be a young stud, one day you will be an old man. You want to get there safely, you want to be able to enjoy your retirement, not laying on the couch with an oxygen bottle.

Don't play games, don't joke about it. It is NOTHING TO JOKE ABOUT.

And for Gods sake don't use the old "its only a little bit" line. All these "little" exposures add up. Like putting that change from you pocket in a jar every night adds up. Next thing you know you have $500.00 in pennies, dimes and quarters and lung cancer.

If every time we grab one of these chemicals, or sand or grind "just one little weld" or weld a little weld without a resporator (weld thru primer is about 99% zinc, can you say "zinc fume fever?) or something, and don't protect ourselves because it is "only one little _______", we are dropping a few coins in the jar by our bed.

Nightfire- if it has been a month then you have nothing to worry about. Just don't do it again! Welding galvanized metal can be very dangerous since it gives off zinc oxide and small amounts of lead. This is one of those things some people do many times and seem to get away with, but the risks are too great and if it does get you then you are in a world of hurt. I am not saying that you should not weld galvanized metal, I am just saying BE CAREFUL! Use a welding fumes mask EVERY TIME such as a 3M 8212 disposable or something similar and do not depend on ventilation alone to protect you. I am pleased to see someone your age thinking about safety as what you do now can have a profound effect on you later on in life. I,like a lot of others,suffer from things I did years ago that I never gave second thought to at the time. You will never regret working safely but you may regret an unsafe act for the rest of your life!

Welded a few pieces of galvanized bar for a seat bracket in a closed garage once. I was sicker than a dog that night. You had better believe I don't even think about welding any galvanized without extra precautions now. I was an experienced welder, it was a cold day and I just didn't give it a second thought when I closed the door. DO give it second thoughts - EVERYTIME.

I work on home respiratory equipment for a living. I'm in and out of the house of people with breathing problems all day long. The most prevalent of couse are the smokers. But after that, are the welders and painters.
