Gas Detectors for Industry

The detection of hazardous gases in workplaces has now become an integral part of ensuring occupational and operational safety. Gas detection serves as an early warning against the formation of a dangerous mixture of toxic or explosive gas with air, thus protecting human lives and property. 

Gas detectors are manufactured in two variants: portable or fixed (stationary detectors). The choice of type depends on several factors, particularly how accessible the area is, whether the danger is permanent or temporary, and how often the concentration needs to be measured. 

The Most Commonly Used Detectors and Their Installation:

Carbon Monoxide Detector (CO): Carbon monoxide has a very similar density to air, so it tends to disperse evenly throughout the room. Therefore, detectors should be placed at the height of a person's face. The breathing zone is usually determined at a height of 1.5 m above the floor.

Typical applications for carbon monoxide detectors include underground parking garages, boiler rooms, factories, and incinerators. 

Carbon Dioxide Detector (CO2): Carbon dioxide is a primary indicator of indoor air quality. By measuring CO2 along with relative humidity and temperature, the level of air quality in spaces can be determined. Air quality is mainly assessed in public buildings such as schools, offices, hospitals, theatres, and hotels. At high concentrations, CO2 can cause disorientation, headaches, then loss of consciousness, and in extreme cases, death. Installing a detector prevents oxygen depletion in enclosed spaces. CO2 is heavier than air and sinks to the ground. However, when measuring air quality, we are interested in the concentration of CO2 in the breathing zone – that is, at a height of 1.5 m above the floor. 

Methane Detector (CH4): It is installed in enclosed spaces where there is a risk of gas accumulation and subsequent explosion. Methane is lighter than air and therefore rises, so the detector should be placed approximately 10 cm below the ceiling and near the source of the leak. The most common uses for methane detectors are in boiler rooms, kitchens with gas stoves, or incinerators.

For better control, detectors can also be purchased with a built-in LCD display, which shows the current measured value. In case of danger, the display will flash.
