How scary. I'm glad that no one was seriously hurt.

I thought that a law passed that all homes need to have both a smoke detector as well as a CO2 detector. I know that my parents bought a CO2 detector but I don't think that they ever installed there's yet. I only have a smoke detector and two fire alarm detectors in my condo which would set off the whole building if I touched them. I don't have my own furnance or water heater so this shouldn't ever be an issue for me. All of my windows do face the parking lot so if someone left their car running for a long period of time and I had my windows open, I guess this could affect me.
