When we talk about workplace safety, the focus usually lands on the obvious hazards: chemicals, machinery noise, etc. However, one of the most common issues often slips under the radar: the air we breathe indoors every day.

Why It Matters
Most people spend the bulk of their workday inside, and if the air quality is poor, it shows. Headaches, fatigue, scratchy throats or just a general feeling of being “off” can sometimes be linked to the building itself. Over time, exposure to things like mold, dust or chemical vapors can cause larger health problems.

Common Culprits
Poor indoor air quality (IAQ) can come from a mix of sources, including:

• Ventilation problems – not enough fresh air coming in, or HVAC systems that aren’t maintained.
• Moisture and mold – leaks, condensation, or high humidity can fuel biological growth.
• Chemicals – paints, adhesives, cleaning products, and even office equipment can release volatile organic compounds (VOCs).
• Combustion gases – carbon monoxide or nitrogen dioxide from heating systems, forklifts or nearby traffic.
• Dust and particulates – generated by construction, manufacturing or even just poor housekeeping.

Where Industrial Hygienists Come In
When complaints come up, an industrial hygienist will usually start by walking the space, talking to workers and checking the basics such as ventilation rates, humidity levels and possible sources of contaminants. If needed, they’ll collect air samples to pinpoint issues. Solutions often focus on better ventilation, fixing leaks, keeping equipment maintained or reducing emissions from products and processes.

Why Businesses Should Care
Cleaner air isn’t just about compliance. Studies have shown that better ventilation and lower pollutant levels improve workers’ concentration and reduce mistakes. Employees also tend to feel healthier and more satisfied with their jobs when attention is paid to indoor air quality.
