The importance of workplace air quality

Pollution in industrial workplaces

We spend a significant part of our lives at work, so breathing clean air in our factories and warehouses is important for our health − just like having fresh air outdoors. And now that global pandemics could become an increasing problem, it’s even more important to think about the quality of the air we breathe.

But did you know that air quality in industrial surroundings is typically no better than outside? In fact the alarming truth is that often it might be worse.

According to the US Environmental Protection Agency (EPA) air pollution at work can be two to five times greater than in the open air. In some extreme cases it can be up to 100 times worse. One reason for this is that wherever goods are produced, processed or stored, there is dust pollution in the air.

Good air quality at work is important for employee health and for your business.

Let's tackle indoor air pollution together!

Common indoor air pollutants


Particulate matter or dust


Nitrogen dioxide (NO2)


Volatile organic compounds (VOCS)

Indoor air quality regulations − the lowdown

There are legal limits to air pollution in the workplace, but they are nowhere near as strict as those for outdoor air. The more that scientists learn about the dangers of indoor air pollution, the more the regulations seem out of date − and could even result in unnecessary risks to workers’ health. In fact the ➥ World Health Organization (WHO) says we should have better laws controlling the air we breathe at work.
