If they are they'll be ringing 100% of the time.

Let's try Carbon Monoxide detectors for $1000 Alex...

And the question is: What new fangled device is being installed above and around remotely controlled ignition sources such as furnaces or sleeping quarters?

The Florida code requires them if you have a fossil fuel appliance, attached garage or fireplace. You should buy one at the same time you buy a portable generator too but it is not really a law.

I do not know what Canada works off of. 2009 IRC (International Residential Code) R315 requires them just outside of sleeping area when fuel-fired appliances are installed or the dweelling has an attached garage.

You would need to look at BC Building Code for reference to Carbon Monoxide detector requirements, or if working in Vancouver then the Vancouver Building Bylaw.

Generally if you have a suite with a fuel burning appliance(range, furnace, fireplace etc.) or attached storage garage you would need a detector. City of Vancouver has a bulletin on this.

This would fall under the Canadian Building Codes. When I built me house I installed the combination Smoke/Co2 detectors. I have no issues with them going off all the time. I run the gas fireplace quite abit and it is 20 feet away from it. Same with the basement and furnace. When I wire houses I always install the combination smaoke/Co2 detectors.

Just don't install one in a garage for obvious reasons!!

You DO KNOW that there's a difference between CO and CO2?

One kills you, the other spritzes your soda.

So stop calling them CO2 detectors.

BTW, if CO2 levels collapsed -- all plant life would be crushed and the harvest would fail.

CO2 is plant fertilizer -- NASA proved that decades ago: they wanted to grow food in space. Today that research has been cranked up with DNA manipulations. Bio-diesel from algae may actually work! It does take super elevated C02 levels, though.

While we were all told that plants take in CO2 and emit O2 ( oxygen ) it's not true that the oxygen comes from the CO2. Decades ago scientists were shocked to find that ALL of the oxygen comes from water molecules -- NEVER the carbon dioxide.

So plants and animals ( and us ) operate on a hydrogen cycle. Food energy exists as the hydrogen bond in carbohydrates -- the oxygen just floats along for the ride.

[ The method was to dope the oxygen with oxygen 18 ( vs oxygen 16 -- the common stuff we breathe ) and follow where it went. It only went one way. ]

Actually both are worth monitoring in different installations.

Carbon Monoxide is a gas that binds with the hemoglobin in red blood cells and doesn't allow them to transport as much Oxygen as they would need in order to support life. Too much CO...you're dead.

Carbon Dioxide is a gas that effectively reduces the partial pressure of Oxygen and can reduce the amount of Oxygen that you can get from the air to a level too low to support life. Too much CO2...you're dead. That was one of the major issues faced by the NASA astronauts on the Apollo 13 mission.

BTW, have you all noticed that hospitals have strict rules on how many plants a patient can have? That's because plants consume Oxygen and give off Carbon Dioxide constantly, but they produce a net increase in Oxygen only when photosynthesis is taking place. Since plants in patient rooms rarely get enough light (of the right wavelength) to give off Oxygen, they end up competing with the patient for the available Oxygen in the room.

Appendix G refers to the National Building Code. Does someone have access to the 2005 building code?
