What's scary about this question is the lack of regard to safety in most US manufacturing facilities that employ lasers. Union shops tend to be up to par with safety standards, but if you go to the smaller shops, laser cutting and engraving is often performed by an unsecured machine with broken or missing cabinet parts or optical fencing. I travel to a lot of these shops to perform repairs on a variety of equipment my employer distributes and I can't remember the last time my log didn't include notes to have sales recommend the needed safety measures for the device. This neglect to safety seems to be just accepted by the workers and met with reluctant compliant by management, with everyone pointing to how inconvenient and "unnecessary" some safety measures are.

If anyone things OSHA has a handle on this issue, they are delusional. Without a major accident happening, most of these small shops can play by their own rules simply because the body enforcing them is stretched ridiculously thin.

So, thank you for asking this. It's insane to me how many do not bother to ask.
