Dr. Smith, pictured in the print, subjected himself to this voluntarily, we find out in a text book on ventilation printed in 1891. His little home was made of lead and the window was there so he could break out if no one would let him out. A more trustworthy assistant would have been nice.
The door was weather stripped with an India rubber tube. Funny how over 100 years later we still could use doors on our homes that work as well as his did!
Well Dr. Smith discovered that fairly quickly the room got unpleasant and moist. He lasted for 100 minutes and then “three persons then went in and at once, pronounced the air to be very bad.” Not sure this counts as science, but it works for me. If it smells bad it is bad. Good enough.
Ironically even today there are ongoing arguments about how much ventilation is needed but we need it. I’ve written about controlling the airways and it’s a good idea to have your ventilation strategies worked out too. Expert advice is only a call away. Don’t worry at GreenHomes America, we don’t use lead rooms and emergency glass.
