Explosive Gas Alarm
So late last night, just as Alan and I were about to crawl into bed, the explosive gas alarm that we have in the kitchen began beeping and flashing the word “gas.” We got up to investigate, but couldn’t find a source. So we called the fire department, shoved the cat in the carrier, put on our shoes, and evacuated our house (in our pajamas).

About a minute before the fire department arrived, the alarm stopped beeping, which is a good sign on the one hand, but unfortunate because we still don’t know what caused it to go off.

The firemen (four of them) swept through our entire house with their own detectors and couldn’t detect any significant amount of gas (only about 1-2 ppm total). They were able to scroll through the history of my explosive gas alarm and saw that at one point it read as high as 33ppm, which is a lot.

We were cleaning a bit earlier. Alan was running the vacuum, and I had sprayed some disinfectant in the garbage can. So, we’re assuming one of those two things set it off. My money is on the disinfectant spray.

I’ve had my explosive gas alarm for about five years now and it’s never gone off before. At least now, I know it works (maybe a little too well).
