How does hog farming relate to industrial hygiene?

In this week's Chemical and Engineering News, Jyllian Kemsley talks to C.J. Backlund, who is an environment, safety, and health (ES&H) coordinator at Sandia National Laboratories, and was promoted in October 2020 to a Distinguished staff member. This comment from her background working in swine-confinement facilities was interesting: 

Thinking about your experience with those swine operations from your graduate school days, is there anything you learned then that you apply now working in a national laboratory?

I hadn’t thought about that before. But, yes, the big lesson was that it’s imperative that we understand the operation that is going on. I’ll be blunt: farmers were dying in those confinement buildings from inhaling the gases and vapors coming from the waste. I definitely learned how important it is to be able to think critically and talk with the people you’re dealing with to understand what the hazards are. That’s the starting point.

Read the whole thing - quite fascinating.
