Underground garages: what could be in the air besides what you can see?

Pollutants in underground garages are not always visible or detectable. As vehicles enter, leave, and circulate, their emissions affect air conditions in a predominantly enclosed environment.

That is why simply observing vehicle movement does not tell the whole story. It is also important to understand what may remain in the air.

What are the main pollutants in underground garages?

One of the pollutants associated with vehicle emissions is carbon monoxide (CO). This gas has no color or odor, making it impossible to identify through the senses alone.

In addition to CO, vehicle emissions can contribute to the presence of other pollutants, such as nitrogen oxides (NOx) and particulate matter, particularly depending on the type of vehicle, fuel used, and operating conditions.

Therefore, a garage that appears clean does not necessarily mean that the air is free of pollutants.

Does an empty garage mean the air is clean?

Not necessarily! Vehicles may have left, but the pollutants released while they were circulating do not disappear immediately.

In an enclosed environment, an appropriate ventilation strategy helps prevent the accumulation of these pollutants and promotes their dilution and removal. Therefore, even an apparently empty garage requires attention.

How can pollutant concentrations be reduced in underground garages?

Ventilation helps move the air and contributes to the dilution and removal of pollutants present in the environment. To achieve this, it is important to consider the dimensions, layout, vehicle flow, and specific characteristics of each project.

Air movement solutions, such as Powerjet and VRG induction fans, can be part of a garage ventilation strategy. Monitoring also complements this process: Sicflux CO Sensors monitor environmental conditions and provide information for system control.

After all, when we talk about pollutants in underground garages, what we cannot see also matters.
