Your wondering if I have ever been to a range based on my stating basic safety protocols makes me wonder if you have ever been to a range, and if you have, please list them because they should be avoided.
We are talking about simple safety precautions, and one of those is wearing a mask. Another safety precaution is to wash your damn hands. So, again, don't touch your face after touching a public handrail. The other factor here is he didn't just disregard at least one of those guidelines, he professed disregarding them. So, zero sympathy.
I mean, you don't promote trigger discipline and keeping the gun pointed down the range because it magically makes people bulletproof. The practice is promoted because it greatly reduces the chances of someone getting shot.
