Good advice, miss K.
I second the kitty lady. CO monitors can go wrong.
I've a good one, for the lab, the one that's installed near the boiler is utter shite. To the point it's dangerous IMO and needs to be taken apart, examined for any useful bits, then chucked, minus any useful bits.
Keeps going off, even when there is absolutely zero chance of their being carbon monoxide produced, because the boiler, is OFF, no flame, no heating on. Ergo-absolute certainty it is the alarm.
So it can only really be either ignored, or panicked over every time it goes off. So it'll have to be dissected and checked for useful bits (like say, the radioactive alpha source in a smoke alarm, usually americium 241, in a very small quantity, but apparently, ones which contain neptunium have been made also. And I really want one, for the element collection. Especially as a really aged one, could serve as a plutonium sample, as Np decays, in the case of many isotopes, to plutonium. I'd rather not have the actinide section have two pieces, and a whole load of empty cases with something dire like the chemical symbol and atomic weight engraved on glass. Having uranium, and americium. I'll always want MORE, until the collection is filled with everything it can BE filled with, including for elements with a nano-scopic gnat-fart of a half life, like astatine and francium, samples of radioisotopes which produce them in the decay chain, a bit of a cop-out, but at least, there'll be some atoms present at all times, due to continuing radioactive decay, maintaining a sample of those elements too unstable, in each isotope they have, nuclear isomers included, to BE stored. If it evaporates in minutes or hours, then it's the only way. And better the second-best than a mere written formula acid-etched into glass.
I might ask my old man for some technetium for xmas actually, as I've seen a place I could be sold a glass ampoule containing a thin backbone of gold, electroplated with a continuous layer of actual technetium metal, as the isotope 99Tc. It's not cheap, though, I don't know if he could afford it. But oh my, I want one, I want one so fucking much you wouldn't believe. Even for a spazz and their spazz 'thing'/s, that, that Tc metal plated onto the gold strip, in an ampoule to prevent it corroding or suffering in any way...my god, I would get on my hands and knees and BEG for one of those.
And there are less reasons I'd ever do that, than there are fingers on the hand of someone born with syndactyly.
