I found this online...I now feel comfortable enough to change out of my brown trousers!
Its amazing that they thought of everything...I'm even happier with my 3m helmet now (assuming I'm asleep at 3am of course!). Sort of makes sense I guess...if 2 welders are working together and one is grinding they'd need protection from the arc uv too.
