Carbon monoxide detector is a life-saving device that alerts you when CO levels reach dangerously high levels. It is a good idea to install one in every sleeping area of the home and near any major gas fueled appliance. These units can be basic battery or plug-in models, or fancier versions that talk, connect to a wireless network or work in combination with a smoke alarm. All meet the performance standards set and enforced by Underwriters Laboratories and are easy to mount on a wall or ceiling.

CO is an odorless, tasteless, colorless and poisonous gas that results from burning fuels without proper ventilation. It can seep into improperly vented spaces around furnaces, fireplaces, water heaters, stoves, grills, generators and vehicles. Exposure can cause a variety of symptoms, ranging from headaches to unconsciousness and death. CO is produced by the incomplete combustion of fossil fuels and also naturally by volcanoes, deforestation and animal and plant respiration.

The best way to prevent CO poisoning is to keep appliances working properly and have them regularly inspected by a professional technician. In addition, have a carbon monoxide detector on each floor and outside all sleeping areas of the home. If an alarm goes off, immediately get everyone out of the house for fresh air and have emergency responders evaluate the situation.

Generally, carbon monoxide detectors sense the presence of the poisonous gas by monitoring its concentration over time and sounding an alarm when dangerous levels are detected. Most have thresholds that vary and are designed to detect low concentrations of CO, giving people sufficient warning to ventilate the area or evacuate. Some system-connected detectors automatically call a central monitoring service if the threshold is reached.

There are many factors that can trigger a carbon dioxide detector to activate, but preventable causes can be minimized through proper placement and education of users. By minimizing preventable calls, those that are truly serious can be taken more seriously and prompt action can be taken to minimize damage and save lives.

When a carbon monoxide detector alarms, the first thing that should be done is to shut off all sources of CO, including heating systems, fireplaces, furnaces, generators, cars and kitchen appliances. Then, remove the unit from its mounting and replace it with a new one, following its instructions. Old detectors should be disposed of at an electronics recycler or hazardous waste facility.

When choosing a carbon monoxide detector, it is important to select a model that can clearly display the measured value. This allows for easy testing and verification that the sensor is working. It is also important to choose a model that is simple to install. This is especially important when multiple detectors need to be installed or when they need to be integrated with a monitoring system. Ideally, a detector should have simple and clear installation and maintenance instructions. These can be found in the owner’s manual or online. Some manufacturers offer detailed video tutorials to make this process even easier for the homeowner.
