Here's another case that could be the whole book in one scene.
A lead safety investigator on the West Coast, about a decade back, starts pulling on a cluster of elevated blood-lead cases at an indoor gun range. The shooters are high. The instructors are high. The cleaning staff are high. None of that is particularly surprising, if you fire a gun indoors, the primer vaporizes a little bit of lead into the air with every round, and that lead settles on every surface in the room. It's a known occupational exposure. People who work at ranges have been getting poisoned for a long time.
What catches him, what he posts his peers about, is the adjoining retail area.
The retail area was elevated too.
Not the shooters. The customers walking in the front door to buy a box of ammo.
The ventilation between the range and the little store attached to it wasn't sealed correctly. The lead aerosol was migrating. People who walked off the street to spend forty bucks on hollow-points were inhaling it while they stood at the counter chatting about their day. People bringing kids to look at the new optics. People buying t-shirts with the range's logo on them.
And nobody had ever thought to check.
Because there is no agency for this.
Not OSHA, customers aren't employees, so OSHA is out. Not EPA, indoor air isn't on their map. Not CPSC, ammunition isn't a consumer product hazard in their framework. Not FDA, not HUD. The state health department was technically involved, but only after enough blood tests had already come back wrong to make it a cluster. There is no CIA for lead. There is OSHA for your job, EPA for your air outside, CPSC for your toys, FDA for your food, HUD for your paint, and about thirty different state health departments doing the actual frontline work with no shared budget and no shared database. Each one sees its slice. None of them sees the aggregate.
Which is why the only person in the country with any reason to walk into that range's retail space and swab it was the investigator. And he only walked in because the BLLs were already coming back wrong.
He was an endpoint job. They all are.
Every person in this book catching lead somewhere it shouldn't be is catching it after the exposure is already happening. That's what secondary prevention is, you wait until someone is poisoned, then you find the source, then you tell the next investigator so the next poisoning gets caught a little faster. Primary prevention, actually stopping the exposure before it happens, is not what any of these people get paid to do. There is no primary-prevention agency. There never was.
So the investigator found the retail problem, measured it, wrote up draft Best Management Practices, posted them to the lead safety peoples group email list, and went back to the next BLL that came in. Drafts are what you write when there is no agency on the other end to approve a final.
That's what the rest of this book is going to be about.
You can catch it with a flashlight and spray bottle in your hands.
