Mains power voltage drop to reduce usage?

IME its a splitting headache and drowsiness.

One can be asleep and stay that way. CO detectors do save lives.

The detectors themselves aren't very reliable, in they they tend to false-alarm before their rated lifetime. Mine seem to last about 5 years. I think the operation is based on irrevsible chemical reactions that can be poisoned by other things.

I think that you are correct. Modern CO and smoke detectors are required to brick themselves when a specified time in service is exceeded, to force replacement.

The ones with a primary lithium battery and 10 year rated lifetimes are great, but they don't seem to last for 10 years.

What defrost system? I just turned it off using the knob inside, which is also supposed to control the temperature (but doesn't). Takes 4-5 hours for all the ice in the freezer part to melt.

It doesn't have a label saying what make or model it is. Maybe at the back, but I don't want to pull it out. Might stop working.

I'm told that for the logs you need a grenade. No, not a Mills bomb but

My typo. Oh well, you knew what I meant!

What about hand washing and manual washing up? Do you have instant heaters for the sink/basin(s)?

In almost all cases, you'll find a label with the model number in the refrigerator section, generally on the hinge side of the interior wall just inside the door.

It’s not really sharpness that you need to spilt logs. The “obtuseness” of the axe is probably more important.

If you look at proper log splitting axes they are much “blunter” in profile that a chopping/cutting axe. This help to split the log open. A slim profile sharp axe will just tend to embed itself as it doesn’t generate enough force to separate the fibres of the wood and “burst” the log apart.

A combination of a proper log splitting axe, a smaller hatchet to use a a easily placed wedge and a grenade will split most things.

Absolutely wrong. I wouldn't be alive to write this if what you say were true. The major health risk to a diver using a rebreather is a failure of the CO2 scrubber, resulting in excessive CO2 in the rebreathed air, toxicity, and a fatality if the diver can't surface. Almost all rebreathers use "nitrox", a mixture of pure oxygen and pure nitrogen. I know. I've used these devices.

Actually, the symptoms of CO poisoning is highly dependent on the concentration of CO in the inhaled air. Relatively low but dangerous concentrations will usually produce a headache and/or nausea as one of the first symptoms. But extremely high levels can produce loss of consciousness as the first symptom.

I should have added that in some diving scenarios, rebreathers actually are charged with 100% oxygen.

Um, no. Nobody puts any CO2 in diving cylinders. Pure O2 is actually toxic over long periods. The higher the pressure you’re breathing it at, the more toxic it is. The presence or absence of CO2 doesn’t come into it.

Not entirely true. We have a “hypoxic drive” to respiration but the CO2 is a much stronger stimulus. We all rebreathe a certain amount of air because of the “dead space” in our lungs so CO2 levels in our lungs and never falls to zero.

So far, I have not had this happen. I write the service date on the bottom of the unit before installation, so I'd know.

Actually, I don't know exactly how the time in service is expired is determined - maybe it counts from manufacture. Although I do recall needing to pull a plastic tab to start or something. Been too long, don't recall.

Normally.

Maybe that someone refills the circuit, not knowing where the slow leak is. Happened to me.

Different kinds.

Current burners switch off automatically way before that.
