Yeah, the N95’s are a good step, but probably not enough. Some people weren’t wearing masks at all.

Also, It didn’t look like any of the saws had good safety stops, the angle-grinders were taped down, and the guy cutting the balls seemed to be really close to getting a (gloved) hand sucked into the saw.

Definitely not the worst safety, but people are definitely getting hurt at this job site. And this is what they considered good enough to show on Youtube, so probably worse than we think…

Very cool balls though.
