wear a full face mask if you can with them, when i was doing my rear axle with them, it was next to the shed with the shed door open, when i was done there was a bit of wire from the wheel sticking ina roll of plastic sheet i had which was a good 5-6 foot away from where i was

on another note a bit has come off and stuck in my leg before too only bout a mil but i felt it
