Is galvanneal safe to weld on?

I work for a large company that builds military vehicles. in our process we have to weld on galvanneal parts. It was brought up during a safety audit that galvanneal causes unsafe fumes during the welding process. since part of the welding is done during assembly and in the open while other people are working on the truck within a couple feet of the welding. I am asking, should we be concerned?

Hi, Carl. The fumes are considered to not be toxic in that it is not currently believed that they cause permanent damage -- but they certainly can cause "metal fume fever". I think those fumes need to be captured and exhausted with effective smoke suckers rather than letting assembly workers breathe them. Then again, personal opinion is that this should apply to all welding fumes, regardless of whether zinc and galvanizing are involved.
