Everyone should have a carbon monoxide detector on every level of your home, positioned near the ceiling, near, but not directly in the path of the flow, to an air or heating vent. This is especially important if you have natural gas appliances or use a generator. 04:17 this morning: beep, beep, beep, beep,.... Woke up the whole house as it is intended to do, but it turned out it just needed a new battery. Last month it was the smoke detectors. Why the hell do the batteries in these things always decide they need changing in the middle of the damn night? I just replaced all of my smoke detectors because they were all older than 5 years. They continued to properly function mechanically, but a friend of mine with the fire department advised to replace them every 5 years because the sensors lose sensitivity over time, just like tritium night sights begin to lose their brightness over time. I hope you all have enough properly-positioned, newer, CO detectors and smoke detectors in your homes, and if not, now is a good time to get or replace them.

One of those saved my bacon once, when I used to fly I put a digital one in my plane and had a quite high reading. Turned out the heat exchanger with the exhaust which provided cabin heat was leaking. Made me mad as I had just had the muffler replaced and they hadn't noticed the hole in the exchanger at the time. For some time I had gotten used to an occasional whiff of exhaust on the ground from open doors and windows and that made me realize the true extent of the problem.
