Mudder Carbon Monoxide Alarm Detector
Amazon's catalog no longer lists this product (checked 2026-11-02). The name comes from the link HN users posted.
Yeah, that's a very good point. It was suggested by an acquaintance that I just throw a lit sparkler down the hole before entering, which _almost_ made sense -though if I ever do manage to find a pocket of CO then it's going to make one heck of a mess.... Davy Lamp time it is then -big flame == big trouble and time to leave.
I might have to start taking a household CO detector with me (the cheap ones now even have a PPM reading [1]) though I'm still wary of it giving a false sense of security and me then missing something else just as hazardous. Once again, Davy Lamp might be the solution to this -apparently the flame goes out when there's 17% oxygen or less, which is still life supporting.
