lol... there's no safety rating.
So what classifies as airborne debris? particulate that probably weighs less than a BB, smaller than a bb and has less inertia so would be stopped by thin plastic.
A directed projectile with 1.5J-3J of energy would probably go right through it.
I futz with V2s, V3s and V6s. I could be wrong... but probably, most likely not, as far as I know.
