Indoor air quality training benefits facility managers, maintenance staff, supervisors and safety teams in offices, schools, warehouses and other indoor workplaces. Employees benefit too, because they are often the first to notice odors, moisture or symptoms. Everyone who can recognize a problem early helps the response team act faster.

Indoor air pollution at work generally falls into three categories. Biological pollutants include bacteria, mold and dust mites from moisture or poor housekeeping. Chemical pollutants include gases from cleaners, pesticides, adhesives and paints. Particles such as dirt and dust often enter from outside. Sources usually trace back to building location, design or materials.

Poor indoor air quality can cause short-term symptoms such as headaches, dizziness, nausea and fatigue. Long-term exposure to some indoor pollutants is linked to asthma, heart disease and cancer. Symptoms that ease after leaving the building are a common sign that the workplace air is the problem.

No, OSHA has no standard specific to indoor air quality. Employers still have duties under the General Duty Clause and under standards for particular hazards, such as air contaminant limits and ventilation rules. OSHA publishes guidance on IAQ, and some states set their own requirements, so check state rules as well.

If you suspect an indoor air quality problem, report it to your supervisor or building manager right away. The IAQ team should investigate, isolate the source and apply controls such as removing the source, adjusting ventilation or changing work practices. Anyone with ongoing symptoms like headaches or dizziness should seek medical attention.
