To protect against unintended cuts, make sure to tuck in your shirt and avoid clothes with dangling sleeves. Another alternative to fully cover your body is to wear a Tyvek suit.

Repeat this step after every cut, even if the edge looks straight.

If you need to cut your fiberglass down the middle, place it across two tables with the center hanging in the air.

If your saw kicks or jitters, turn it off and hold it in place. Give it a moment to rest before continuing.
