FAQs:

How many carbon monoxide detectors are needed in a house?

It is normally recommended that each floor should have carbon monoxide detectors. Besides, they should necessarily be installed outside every sleeping area.

What is the best place to install carbon monoxide detector in home?

To maximize protection against the hazardous effects of carbon monoxide, detectors should be placed ideally in the following locations:
a. Each floor should have a carbon monoxide detector
b. Attached garages – if your garage is attached to your home, there should be one placed near the area. Running vehicles produce carbon monoxide which can easily spread to the rest of the house. With carbon monoxide detector installed in the attached garage, you’d be warned of the problems resulting from high level of carbon monoxide concentration.
c. All sleeping rooms – high level of carbon monoxide might occur at night time when everyone is sleeping.
When CO detectors are placed outside or near all sleeping rooms, it will easily alert everyone in the event of CO concentration climbing up to a dangerous level.
It is important to mention here that carbon monoxide alarms can best detect the concentration level of CO when installed five feet above the ground. Besides, depending on the CO detector’s specifications, it is important to know the guidelines from the manufacturer to help decide on the number of units to be installed.

Should carbon monoxide detectors be installed on the ceiling?

Typically, carbon monoxide detectors are installed 3 to 5 feet or 1 to 2 meters from the floor when the ceiling is around 7-10 feet high.
You can also install them on the ceiling as well to make sure that they are above any obstructions to allow the free flow of air. However, the first option is the ideal case because CO often tends to mix with air and that must be avoided for detecting it accurately.

Where should a smoke detector be placed in a bedroom?

Every bedroom should have a smoke detector installed inside and it should be mounted at least 4” from the junction of ceiling and wall.

What to do if carbon monoxide detector beeps?

Whether you have a typical CO detector or a more sophisticated one with 4 gas meter alarm levels, it is important to know the things you should do once you hear your carbon monoxide detector beeping. Instead of panicking, do the following few things:
a. Open all windows and doors to get air ventilation.
b. Switch off all appliances.
c. Reset the detector after there is air ventilation.
d. Call a technician to check the detector if it doesn’t sound again.
e. Call the local fire department when the detector alarms the second time.

What appliances create carbon monoxide gas?

In the event fuel is burnt due to combustion, there is the presence of carbon monoxide which can’t be seen or smelled. Typical home appliances that produce carbon monoxide are gas clothes dryer, fireplaces, gas water heaters, wood-burning stoves, gas refrigerators, oil or gas furnaces, charcoal grills, and space heaters, among various others.

The Bottom Line:

Carbon monoxide is popularly called as the silent killer because of its invisible and odorless properties. Slight exposure to this gas can be harmful and, if heavily exposed, it can be lethal and dangerous.

This gas can sneak in and spread around the house without your knowledge and anytime can result in dramatic hazards if not quickly taken care of. Since most of the time this gas comes from home appliances, it is very important to take extra precautions before it creates a huge problem.

Carbon monoxide facts show that a significant number of deaths have been reported to result from carbon monoxide poisoning. So, this issue should be taken seriously.

Probably, carbon monoxide detectors and alarms offer the best solution to keep things under control and have efficient carbon monoxide detection.

The number of carbon monoxide detectors and alarms available in the market today is continuously on the rise and you have the option of choosing from amongst a variety of options with differing features, price ranges, and capabilities.
