Here's my take. Long story short, occupational hazard.
1) I have been going there since 2016 on various days (excluding Mon/Tues). When ever I go, I always see the same RSO's. So add in that they're there all day since I'll bet prior to 2016 and more like 15+ years, this was bound to happen over time. It's not like it happened in 1 month or 6 months.
2) I have seen RSO's eating food at the firing line, behind people while they are shooting. I have seen them grab donuts and other bare handed snacks before washing their hands. So I'm sure this contributes to it. If someone did this once a month, you're probably be OK. Even a few times a month. But on a daily basis over years is a diff story.
3) KKSC is already outdoors and not much more 1 can do besides not doing #2 and rotating the RSO's. Have them work at other parks for X amount of time then go back. Or even put a cap, after X years, you are moved permanently to another park.
4) I've heard people saying they should be wearing mask, again they would have to be fit tested and OSHA followed. Which by #2 above, they're not doing. As we have seen from COVID, even with N95 type respirators, majority of people are not wearing them correctly anyways.
5) Indoor ranges have special air systems. These filters cost about $15K each and need to be replaced like once a month. 808GC was not doing this correctly so had a few guys with higher lead levels, even regulars who hang there often had elevated levels. They have since corrected this once the current owner took ownership. So this was the previous owner who had this issue. And if anyone can see their roof, you can see all the soot on it. Which makes you wonder what isn't being filtered out.
I hope the best for all the RSO's affected and hope this event combined with others doesn't shut down the range. In the mean time, the 2 indoors will see a huge jump in revenue. I'm not a fan of either, but of the 2, I will be going to 808GC specifically to zero my RDS on my Shield. I'm even debating just leaving it zero'd to my ironss cause it's guud enuff until I go to Vegas in a few months and can hit up the indoors up there.
If anyone wants to know why, then I'll post it if requested. We all have our own reasons.
