Better safe than sorry.
I live close to the University of Arizona in the heart of the Tucson. I'm getting ready to install a steel fence around the front of my property and have been looking into the safety issues. I've come to the conclusion that I need to use a couple of welding curtains to block the ability of anyone seeing the arc from the street. In this day and age you do not know when someone will sue for supposed damage to their eyes. I just do not want to deal with the expense of defending myself from a lawsuit from an individual that does not want to work for a living.
