I'm sorry! but u have to look out for your employees saftey!

Winning may depend on how your work stations are set up. Is this a wide open shop? Here we have as many as 16 welders in the same bay(39 in all). Some may be welding while others are doing other duties, but they are all in the same bay together. We provide portable welding curtains that the welders can place between them and the work station next to them if the welding bothering someone. All of our tables are equipted with two employees, a welder and a fitter. The fitter will also weld, so there are times that both guys are in close proximity of each other and the curtain would then be place between them. If your shop is set up similar and you have curtains sitting around the shop that are available for use, I would say you have no problem, unless the employees were not using them. It is your duty to enforce rules making them use the curtains when necessary. Vistors have signs posted at all entrances to the shop stating not to look at the light from the arc. So, it's up to them to use their hand if necessary to breifly shield their eyes as they pass a welder in action. I've been through several audits and only challenged one time and I had a guy that was cutting with the O/A torch and only had his clear safety glasses on rather than the #3 shade glasses he was provided(and normally uses). I had to post a Memo to show that I had informed all employees that is was a requirement and not an option. They then reduced it after they saw we corrected the situation.
(ie. http://img.photobucket.com/albums/v345/jwright650/welding%20pictures/Dsc00006.jpg) Note that the welders are welding on the same end of the column right next to each other(can't see one of the guys nearest to the camera) and there is a curtain standing between them.

EDIT: (the template board you see in the picture was added, usually the red curtain is enough protection to satisfy the auditors)

We got away with issuing #2 shaded safty glasses in our shop.after osha wanted us to install safty curtains
