Texas state code requires machine rooms for ammonia systems to get 30 air exchanges per hour, same state building code requires houses to be under 1/3 air excha

Texas state code requires machine rooms for ammonia systems to get 30 air exchanges per hour, same state building code requires houses to be under 1/3 air exchanges per hour. I'm a little fuzzy about the later, pretty sure about the former, and most people don't have the privilege of living in Texas (not sure if I'm kidding or not?), but it demonstrates the safety issue that ammonia cooling needs about a hundred times as much ventilation as a normal kitchen. And insert the usual quotes about building codes being written in blood so they aren't demanding a hundred times the ventilation just for fun.
