Garage brewing and carbon monoxide

I think there are quite a few people brewing with a propane burner in a garage. Was wondering what others do for ventilation to avoid carbon monoxide poisoning? Open the garage door wide open? Just leave the side door open?

I brewed yesterday within a double car garage and I opened a side window plus had the side door open. During heat up to mash my carbon monoxide detector went off so I guess that isn't enough....

Mike and I when brewing at his place leave the door open about 1.5 feet when the burner is running. So far so good and we are both still alive and have had both burners going at once.

This reminds me, next time I brew a batch in the garage I'll put a CO detector out there just to double-check...

Just FYI,

Carbon monoxide rises with the heat as it's roughly the same density as air. I know that most folks just crack the garage door, and that works, but unlike CO2 which sinks, CO mixes equally at all levels in the space. Just make sure you have good air flow to avoid getting sick. Maybe that headache you have after brewing is not due to Keith's DIPAs!

I might not be doing enough, but during the winter I keep the burner next to the side door and keep it open a few feet, and I have a standing floor fan that I run next to it. I was mostly doing it to blow the steam out, and it works pretty well, but maybe I should have the window open to allow extra air flow.

In the summer, of course, I just keep the big door open.

I have a 16x8 foot garage door I keep wide open along with the back door and a side window. Perhaps overkill but I'm not taking any chances.

CO detectors are too cheap to do without.

I just dress really warm and open up the shed door.

My wife tells me about a guy in Berwick that BBQed win the garage with the door open and wound up blowing up his garage....so I'm banned from that winter activity. Ha ha
