How do gas detectors work?Mayara
Did you know that a gas leak could be occurring in your house, apartment, or office building right now, and you won’t even notice? The majority of gas leak accidents happen due to Carbon Monoxide, which is known as the “silent killer.” That is one of the main reasons you need gas detectors installed in your house and your office. However, if gas leaks are nearly impossible for us to identify, how do gas detectors work? Find out in the article below.
How do gas detectors work?
Gas detectors use a sensor to measure the concentration of specific gases in the atmosphere. While early instruments were able to detect only one type of gas, modern equipment can measure several types at once. Gas detectors are most commonly used to measure oxygen (O2), flammable gases or vapors (LEL), hydrogen sulfide (H2S) and carbon monoxide (CO) concentration.
The sensor inside the detector serves as a reference point and scale. Therefore, when a chemical reaction caused by a specific gas occurs, the sensor produces a measurable electric current. By monitoring these currents, the equipment will alert its user when the presence of gas is near any hazardous amount.
Technicians recommend the use of most gas detectors for up to three years since their sensor has an expiration date. From time to time, it is also imperative to check the equipment, making sure it’s functioning properly.
Why do I need a gas detector?
For residential buildings, the most common use of a gas detector is to avoid accidents involving high Carbon Monoxide concentration. Carbon Monoxide is a colorless, odorless, and tasteless gas formed by the incomplete combustion of carbon compounds, like gasoline, wood, and natural gas.
There are many places inside a house where Carbon Monoxide might accumulate. A few examples of where you can find high concentrations of CO might be in garages, furnaces, dryers, water heaters, space heaters, cooking appliances, and wood-burning fireplaces.
The risk of Carbon Monoxide poisoning is higher during cold months and can even lead to death. Carbon Monoxide is the second most common cause of non-medicinal poisoning deaths in the United States. According to the CDC, at least 430 people die in the U.S. from accidental CO poisoning every year. On top of that, approximately 50,000 people visit the emergency department each year due to accidental CO poisoning.
Such statistics have led several states to create laws that mandate the use of gas detectors in residential buildings, offices, and industries. The rules vary from state to state, but the majority have implemented strict regulations on CO detectors.
Where should gas detectors be installed?
In addition to smoke detectors, many local jurisdictions in the United States require the installation of carbon monoxide detectors in houses and apartments. Besides residential buildings, technicians can also recommend the installation of these sensors in industrial plants, refineries, factories, and office buildings.
You might find gas detectors inside parking lots, mechanical rooms, office towers, commercial buildings, shopping centers, schools, and laboratories.
