Welders beware!! Read this......!!

Any HVAC / refrigeration tech who has ever brazed refrigerant tubes using Freon based refrigerants knows this. However, there is OTHER stuff that can kill ya. Plating on steel, including but not limited to GALVANIZING.

In 2003 when I was restoring my 70 Charger, I took the headlight mounting buckets to the table and ran them over the wire wheel to clean them up. About a half hour later I had some dizziness and a headache that lasted for hours. Someone told me later that the galvanizing compound is hazardous once it becomes airborne.

Correct. In my view anything on these old cars, once airborne, is bad for you. I was welding in a floor pan yesterday and noticed the undercoating was smoking a bit. Had a headache last night all night. I even use a fan to direct fumes and smoke away from my helmet. We gotta THINK before we DO or we wont live long enough to enjoy these cars.

From years of breathing dust and fumes etc, my 'allergies' today are very sensitive. Just doing BBQ now messes me up. At least headaches isn't part of it....
 
Hey all,

I saw this on another site and thought it deserved to be posted. Read it.

This was published in American Iron Magazine in the August 2009 issue.

Brake Cleaner = Phosgene Gas

By Steve 'brewdude' Garn

Yep, I thought this time I was a goner! How simple it was to get in trouble. Please take the time to read this and pass it on. After time we see and read many warning labels that we no longer heed. We buy chemicals and sprays at a local parts house and think to ourselves how can this be so bad health wise if we use it, I am buying it over the counter? So, this is how my story starts.

So I had a rush job welding 4 diesel semi tanks to patch that were pitted from road salt corrosion. Normally I spray a little carb cleaner, wipe it off, light the acetylene torch and preheat to get rid of any solvents. The gas station close to the shop was out of carb cleaner so I picked up a can of brake cleaner and went thru my regular routine. I even had the shop door open and the exhaust fan on. I started TIG welding (3pm Thursday) and had no problem in the beginning. Then, I started welding across a really pitted area and came across a couple of drops of cleaner still left in a deep pit. When I came close a small puff of white smoke puffed and immediately almost passed out. I then made it outside and sat for a while in the fresh air. After about 10 minutes I went to the office at the house and sat at the computer to check the warnings on the brake cleaner can when my whole left side started shaking for about 10-15 minutes. The can said ‘Vapors may decompose to harmful or fatal corrosive gases such as hydrogen chloride and possibly phosgene.



After reading about Hydrogen Chloride and then started researching phosgene. The chemical in the brake cleaner is Tetrachloroethylene. When this chemical is exposed with excessive heat and argon (used in MIG and TIG welding) it also produces phosgene.

Some Phosgene facts. Google Phosgene and read more!

It can be fatal with a dose as little as 4 parts per million.

Symptoms can be delayed from 6-48 hours after exposure.

There is NO antidote for Phosgene.

Long term effects can be chronic bronchitis and emphysema.





My breathing still was hard. So I called my wife in town (20 mins. away) and she said to call the ambulance which I didn't do. I waited at home for another hour and felt a little better so I decided to drive into town and meet my wife for supper and also living way out in the country brought me closer to the hospital in case I felt worse. The chlorine taste and smell in my nose and mouth was still very strong but went out later for pizza and then went to watch a basketball game. I felt a little better until I went outside after the game into the fresh air and then the smell and taste of chlorine almost overwhelmed me. I still went home hoping time would make me feel better.
About midnight (Thursday) I started coughing, my chest started hurting but thought that this would pass after a nights sleep. The next day (Friday)symptoms got worse and kidneys started hurting so I drank a bunch of liquids and cranberry juice. For 4 days pissed a lot of clear fluid with no smell. On Saturday I was really in a lot of pain. On Sunday I felt a little better and went to a friend’s house to watch the superbowl game. When I came home I felt very weak and tired. Monday I still was about the same. Tuesday I felt a little better and went into the shop for a couple of hours. Piss was very dark and a lot of smell this day. Still couldn't crap. Wednesday felt pretty good and I worked for about 5 hours. Thursday was even better day so I decided I would drive to Cincy with Chad to the VTwin expo on Friday. I felt okay but was very tired and weak. That Saturday I went out with friends but I didn’t feel quite right. I felt crappy on Sunday and left the expo about 2pm. The trip home was 375 miles and arrived home about 10pm that night feeling very tired. My wife made the comment that I looked awful (some home greeting). At midnight I lost all balance, was dazed, confused and could hardly talk so I then went to the Emergency room. My symptoms were Oxygen level low, sugar out of control, vertigo and I was hurting badly in my entire chest. They admitted me and put me in the ICU. They said my kidneys had probably shut down for those 4 days, my lungs were damaged so I had to be on oxygen and that I would have to be on insulin to keep my sugar in check. The doctor and neurologist called CDC to try to figure out what to do since there is no antidote for phosgene. Basically to try to rest and hope it gets better. After CT, MRI, EKGs, EEG and several other blood tests it looked like at this time there was no permanent damage. The EEG was taken because of the shaking earlier of my left side was a seizure caused by the chemicals. The EEG determined that there was no permanent damage. But the MRI showed fluid in sinuses and a build up of fluids near the brain. The gas scarred up my sinuses and then became infected causing these fluids. The 3 doctors I saw said I was really lucky to make it.
Now it has been 4 weeks. Another Doctor who specializes in toxology is now seeing me. He thinks I may have emphysema and chronic bronchitis. So at this time I am on nasal medicine and an inhaler. My sinuses are severely scarred and nose smell nerves are damaged. I still have that awful chlorine taste and smell. I am also going to ear, nose throat Dr on Thursday. I will also know later on any pancreas damage from the blood tests that I had taken. The insulin that I was taking had little effect on sugar and I can't keep it in control. So we are trying a different approach with Lantos (long lasting insulin) and other medicines. Sleeping is off and on and I will have a sleep test next Tuesday. I am feeling somewhat better but still very tired. This will go on for a while but I have full faith that all will be fine after time.



On some forums some suggest using a cleaner without this chemical. Other chemicals I found in other sprays in my shop include, xylene, toluene, methylene chloride, ketones, pentane, cyclohexanes, heptane, methyl ethyl ketone (MEK), methanol, tetrahydrofuran and petroleum napththa. There are actually more but you get my point, right? All the chemicals listed above have heath issues! So check your sprays and know the health hazards and their correct use.

Chris Maida has called and checked up on me several times. He said it is a shame I went thru this ordeal. But, I disagree. If it saves someone an illness or a death it is worth going thru this if this is what it takes.

Please read labels and warnings. Look up the chemicals you use. Also keep these sites and phone numbers nearby.

Go out in yer shop and read all of the cans of stuff you have been using every day, be wise, stay alive.

Thanks for sharing, I find this to be very educational.
 
When I was reading about the phosgene gas, it was used in World War 1.
I don't think the Argon or heat causes the reaction? I think it is the UV radiation from the welding arc?
Quote from an article I read:
"The intense UV radiation from arc welding can cause a chemical reaction with some chlorinated chemicals (such as some spray brake cleaners), most likely or commonly containing 1-1-1-trichloroethane"
 
Yep.
Back when men were made of iron and boats of wood, we would clean our tools off with 1.1.1 (Inhibisol).
Then our hands.
Now I've got MSDS overload of the brain.
 
Holy crap. I never gave any of this stuff much thought. Great article. Glad i read it. I will be sure to pass this along to my boys. I will be looking around in my garage today and make sure none of this stuff is out there.
Thanks for sharing Ghostrider 67
 
Thanks for posting this. I used brake cleaner last week to clean off my sheetmetal and started welding on it right after. Felt dizzy n started vomiting uncontrollably n could not breath. Had no idea why n i think i found the culprit. Thanks
 
I have another warning to add about cleaners.
Back in the early 70s I was a production Welder at GM. Was welding aluminum AC Evaporators on the assembly line. About 50 welders per shift. The parts were cleaned in tricloretheline. After the rinse cycle they were transfered to the welding Dept.
Triclore fumes mixed with argon and TIG Welding creates Phosgene Gas ! Instant Problems. These gas Fumes are heavier than air and settle to the floor and in to the porus surfaces.
We had a problem with the dept ventilation system and rinse cycles. Management (typical) did not immediately fix this. When the day shift started welding (friday), the gas was stirred up from the floor.The Gas hit the welders like a knife in the kidneys and every thing shut down. We went on a Wild Cat Srtike (both shifts)! Shut Down half the plant (no parts from the welding dept.).
UAW National showed up Saturday for emergancy meetings. Ventelation fixed on sunday! Back to work on monday. The parts cleaner Dept was moved to a safer location. As typical Management is at fault. You have to kick them in the N_ _ _ _ to get action. .... This was the only Wild Cat Strike in the Plants History !
Bottom line ...Clean parts and proper Ventelation ...Do Not be in a Hurry. AVIDFLYR 64 Polara
 
Again.....everyone is very welcome for the posting. My wife got me a 36 inch shop fan on wheels that swivels for fathers day. Worked great to blow the gases away from my work, and my lungs. I am praying that the crap filled sand in Iraq wont come back and kill me at a later date. I don't want to do myself in at this point by being lazy about safety.
 
I made this movable welding vent out of a 12" sewer ventilation tube and a 10 amp 1750 cfm fan. Sucks the fumes away.

Quite a read, and points taken. The LAST person I would call if having trouble breathing is my wife.
 
Well folks, I didn't take my own advice yesterday and ended up "flashing" my eyes while welding. The right one seems ok but the left is sore and scratchy and itchy and swollen. It's a little better since last night when it happened but man, what a PITA. When tacking sheet metal either shield the flash with your free hand or use the hand held shield if you get sick of flipping the helmet up and down so often. As for remedies I read that Potato slices, cold ones, helps a lot when laid over the eyes. Doctor recommended.
 
Well folks, I didn't take my own advice yesterday and ended up "flashing" my eyes while welding.
If it doesn't clear up in a day or two, or you might just go anyway, to the dr. and get some antibiotic to put in your eye. The "sand in your eye" feeling are little blisters on the eye.
If you even wear a grinder shield when tacking will help a lot. But the best thing for tacking is the auto darkening lense. I like the large one.
I've seen guys tacking, turn their head when pulling the trigger and the uv hits the inside of their safty glasses, bounces off and right in the eye!
 
35yrs ago I worked in an auto parts store,we mixed paint there as well. Dulux enamel,Centari,and good old fashion lacquer.The salesman used to come in every morning and soak a rag in lacquer thinners and hold it up to his nose and snort it! He said it was the only thing that would clear his sinus' .He died about a year after I met him Ifigured he was close to 70-75, turns out he was only 48! Did him a lot of good didn't it.
 
Well, 4 days later now and it has cleared up mostly. I still have a bulge of fluid like a bag under the eye but that's probably from me rubbing it more than the flash. The white is not red anymore or itchy. So good result and the potatoes slices worked very well to relieve the sand paper feeling. Good lubricant!
