I am a machine welder and just found out that I am pregnant

People at my work have told me before I found out I was pregnant that the smoke is not good for you to breath in. The mechanics told me that I could pass out from the fumes because there are no hoods on any of the machines and if I start to feel nauseous to go get a milk. I guess milk will make it better. I recently found out I am pregnant and do not want to take any chances in the smoke harming my baby. Is it safe to be working with while pregnant?

First of all, let me say that I'm not an industrial hygienist or doctor. You should consult one. But, following the advice below will do you no harm.

First, if you're welding pieces that are galvanized, the zinc burns up and makes a fume that can make you sick as a dog. I speak from experience. You should be wearing at the very least, an air purifying respirator when you are doing this work.

Second, if you weld stainless that has chromium in it, the fume from that can have hexavalent chromium in it. Again, at the very least, an air purifying respirator.

Third, there's a class of solvents called "cellosolves." They're not too toxic, generally, but they're known to do harm to pregnant women. You may not use these solvents at all in your plant, but if you're around solvents, ask what solvent it is, and if it contains one of these chemicals.

I am pretty sure that there are protective measures that will allow you to do your job safely. But, again, check with a real expert.

Good luck, and the best to you and your family.
