A good pair of industrial-grade safety glasses and/or a face shield are just about essential to any job with hazardous liquids or grinder sparks involved. Several years ago I tripped over an air hose in the shop, with both hands full, and did a face plant onto a vehicle lift pad 4 inches off the floor. No chance to try to cushion the fall at all. I fractured my left eve orbit in four places and needed over a dozen stitches to close up the cuts on my cheek, but my polycarbonate lens safety glasses saved my eye. The shape of the bruises and contusions exactly matched the shape of the glasses. The lens was badly scuffed up, but it didn't break.
When venting pressure from a spray can it's a good idea to wrap a couple of layers of shop towel around it, and [censored] a TINY vent hole in it with an ice pick
