    What is so safe about welding on stainless??

          Sure, some people smoke two packs a day and live to well into their 80's, but these people are outnumbered by those who suffer from serious medical complications.

          Some of the advice given out in this thread is downright irresponsible. Zinc fumes can make you very sick, and possibly kill you. The cadmium coatings on grade 8 bolts is even more deadly in smaller doses. Don't take a chance with this stuff, at the bear minimum wear a resperirator. I personally use the 3M resperirators with 2097 cartidges, as they work and fit under the welding helmets okay. (Miller elite, a Jackson flip front and a Techmen autoshade)

          Once again, and I can't stress this enough, don't risk your health over something silly like this, take the proper precautions. Just because it doesn't effect you immediately, or the weak after, doesn't mean it isn't harming you. You only get one shot on this planet, why make it any shorter or sh*tier by choice.

            Well, you pulled the trigger...what is irresponsible? Spit it out. We have tons more experience welding dangerous stuff than you do. Some of us actually do know what we are talking about. So, what is irresponsible?

                Telling people that it is fine to just keep your head out of the plume, hold your breath, drinking milk and so on. There is no substitute for proper safety, which in this case would be a respirator at the bare minimum. The more ventilation, obviously, the better.

                    My nuts and bolts are nickle or chromium plated that I have to weld on to. The only galvanized nuts and bolts I ever saw were used on chain link fencing materials. As a rule, any welding smoke is generally not good for ones lungs. Smoke from galvanized is even worse. If I have to weld on galvanized, I grind off were I am welding, if I can, make sure I'm up wind not down wind and also that there is plenty of fresh air around.

                      Well, I made a career out of welding galvanized. The instructions I gave him are exactly what I did. I have had numerous blood tests, physicals and so on and I have zero issues with the zinc. Using common sense will prevent any issues. If that is beyond your comprehension, I can't help that. To call me irresponsible for it is asinine. I do not put myself at risk nor do I put my employees at risk. I have to continue on and move to the next job. Deliberately making me or my guys sick does not get the work done. Read the AWS pages linked above. They say the exact same thing I said. They say to use a respirator when adequate ventilation cannot be gauranteed.

                      In this case, the man is welding small bolts and nuts. From his post, it doesn't sound like it will be 8 hrs a day, but rather a few now and again. Now here is when the common sense comes in. Respirators are only required when the PEL is reached or can be approached. Welding small amounts, even a dozen bolts will not even approach that level. If he is only welding a couple of bolts, he does not need to do anything more than what I said. Respirators are almost never needed outside. Stay outside and do it right, and he will be fine with zero exposure. This stuff isn't rocket science and is pretty easy to figure out as long as you don't flip out and start scaring the women with all the tall tails and overly protective crap.

                      You also need to get your facts right. You prescribe a 3M 2097, correct? Here is what 3M says about that cartridge." P/n 3MR 2097 - P100 filter with Nuisance level Organic vapor relief. Nuisance levels refer to concentrations below OSHA PEL. Relief refers to the irritating effects of the gas or vapor identified and is not intended for respiratory protection." Those filters also have a 40 hr maximum use span and or 30 day time frame for replacement, whichever comes first. Those limits come directly from NIOSH. So, if you think that respirator will protect you from all fume exposure, you are sadly mistaken. They are for limited exposure only. They are not a protect all or cure all. If you had a little more time doing this stuff, you would know that. You say he needs a respirator at bare minumum, the AWS disagrees with that as well.

                      So, who is being irresponsible again?

                        Cadmium and grade 8 hardware was also mentioned. The vast majority of the grade 8 hardware available today is actually zinc dichromate. They quit using gold cadmium for the most part due to toxicity of the cadmium. If you buy new gold hardware, it is most likely a zinc dichromate.

                        G-8 hardware doesn't always appear as the gold stuff you see at the hardware stores. It can also be straight zinc chromate, which is the common silver coating, zinc phosphate, which is a black to gray even coating, and phosphate and oil, which looks like the zinc phosphate with a slightly to heavily crystalized appearance.

                          Oh nuts...

                          Well, I guess the key is to avoid it whenever possible. I have been threading my own rod and taping pieces of plate to make my own nuts to avoid most of it.

                          It does beg the whole issue about setting up some decent ventilator for my welding area though, even for just the everyday fumes.

                          Thanks so much to all who chimed in...

                            As long as you are not doing a huge volume inside, a simple box fan behind you would help a great deal. Don't remember if you mention which process you were using, but with a fan, care should be taken with MIG and TIG. The fan will blow the shielding gas away and then you have more problems. You can also cobble up a simple exhaust system over a work table very easily. Small blowers and ducting or even bath type fans will do a very good job on smoke or fume removal.

                            FWIW, I weld on bolts all the time. It isn't a big deal at all. Just do it and be smart about it and it will be fine.

                              Many of the older guys I work with have the same attitude. I've been doing this for x amount of years and nothing has gone wrong, so clearly it's not harmful. That's all wonderful until something does go wrong. I know several people who use to ride without helmets, saying that they rode well enough they didn't need them. One in particular had a bad crash one day, smashing his head very hard. Luckily he surrvived, and now that he has a second chance he wears and advocates the use of helmets.

                              I never said that breathing in fumes would kill you instantly, and small doses on the odd occasion may not cause any noticable side effects. However, many of the chemicals, fumes and vapours dealt with in welding have LONG TERM side effects that do not manifest right away. Once again, much like smoking, it doesn't kill you right away but how many people have died of lung cancer later in life?There are enough things in our lifes that threaten to shorten it, if you can do something to help yourself out why wouldn't you?

                              As for the respirators, I am well aware that the particular model I am using would not be sufficient for a 10 hour day in a holding tank welding galvanised parts, however it certainly does help to block fumes and dust. I also change my cartridges out periodically as a preventive measure.

                              Since this is a board that has a wide variety of users, some of who take others situations and apply their own interpretations to there own situations, which are often different, I find it prudent that safety should always be stressed and encouraged.
