And did you know that the senior technical advisor for the National Propane Gas Association, had no idea that people made beer in propane turkey fryers until he was interviewed on Basic Brewing?
And pretty much spoke the party line of propane usage, which most of us pretty much ignore anyway.
Propane Safety and Tips on Basic Brewing Podcast.
And iirc neither did the makers of said Turkey Fryers know how we've coopted their product for our hobby. And said something similar.
Did you ever read the warning labels on a bottle of starsan? And did you also know that the required labelling about contact time is longer than it actually is, that it kills much faster than that but 5-star is required to have that info, but if you listen to the podcast here, he goes into the more effective way to use it. And talks about the FDA rules.
It's called "cover your a$$." And it's usually done by lawyers. Warning labels, usage "policies" are often written with oversight by lawyers to cover their a$$e$, or is it a$$et$?

People are essentially stupid...and Lawyers are smart enough to cover their clients ass with warnings.....like warning on cruise controls in campers, not to engage them, and get up and go to the bathroom...or other fun things like these...

Also Has anyone EVER called a customer service number, and EVER got anything that was more than a canned answer? You don't get much out of the box thinking when calling a 1-800 number, especially if you're going to be connected to someone in India. They are going to read whatever they've been told to read, say whatever they've been told to say.
Bottom line, we've been using them for quite awhile now. And some folks choose not to and mash in kettles....So it's ultimately up to you.
