I found that cutting metal with a miter saw was touchy, although perhaps a different blade would have done a better job. I used a lot of safety equipment and still felt like I was under protected. You'll be dealing with sparks and metal shards. It's not an indoor job. Cutting with tin snips felt much safer, but you need to make sure not to cut yourself; The tin snips are sharp. The raw edges of the tiles are sharp. I recommend using gloves. You may also want to wear eye protection.
