Why Indoor Air Quality and National Safety Month Must Go Hand in Hand
Every June, the National Safety Council leads National Safety Month, a vital campaign aimed at reducing preventable injuries and deaths, both in the workplace and at home. Since its inception in 1996, the campaign has equipped professionals and the public with the tools and resources needed to prevent accidents, promote safety, and protect lives.
But as we examine the most pressing threats to public safety, one risk remains consistently underestimated: the air we breathe indoors.
An Unseen Hazard: Indoor Air Pollution
The U.S. Environmental Protection Agency (EPA) ranks indoor air pollution among the top five environmental risks to public health. Despite this, the issue often receives limited attention in occupational safety and public health campaigns.
Indoor environments, where we spend approximately 90% of our time, can expose occupants to a complex mixture of pollutants. These include volatile organic compounds (VOCs) emitted from building materials and office equipment, allergens such as dust mite allergen and mold, and particulate matter from inadequate ventilation or filtration. Together, these factors contribute not only to discomfort but to serious and preventable health risks.
The Impact on Health and Productivity
According to the American College of Allergy, Asthma, and Immunology (ACAAI), approximately 50% of illnesses are either caused or exacerbated by poor indoor air quality. Children are especially vulnerable, with exposure linked to higher rates of asthma and other respiratory conditions.
The statistics are sobering:
- Over 50% of U.S. homes have at least one indoor allergen at elevated levels (NIH).
- 90% of household dust contains harmful chemicals, including flame retardants (Environmental Working Group).
- Air-tight buildings, designed for energy efficiency but lacking proper ventilation, may trap up to 400 chemicals indoors (ASHRAE).
- Sick Building Syndrome (SBS) continues to affect office workers globally due to emissions from electronics, furniture, and synthetic materials (EPA).
These realities translate not only into health burdens but also into economic ones. Poor indoor air quality can reduce worker productivity, increase absenteeism, and contribute to rising healthcare costs, all of which are relevant to any discussion on safety in the workplace.
The EPA’s Three-Pronged Strategy for Healthier Indoor Air
In response to growing evidence of IAQ-related risks, the EPA has outlined three core strategies for improvement:
- Source Control
Reduce emissions at the source by selecting low-emission products and materials, such as Asthma & Allergy Friendly® Certified paints, flooring, and insulation. - Improved Ventilation
Increase outdoor air exchange through mechanical or natural ventilation systems to help dilute and remove indoor pollutants. According to ASHRAE, effective ventilation can also reduce energy costs by up to 30%. - Air Cleaning and Filtration
Use appropriately rated air cleaners and HVAC filters to capture airborne allergens and particulates. Devices that incorporate HEPA filtration or meet stringent third-party standards provide added assurance of performance.
These strategies are not only applicable in homes but also in schools, healthcare settings, and office buildings – everywhere we live, learn, and work.
Building a Broader Definition of Safety
As we observe National Safety Month this June, it is time to expand the conversation beyond accidents and injuries. Indoor air quality is not a peripheral issue. It is a foundational aspect of health, productivity, and safety in the built environment.
At the iAIR Institute, our mission is to equip building professionals, health advocates, and decision-makers with the science and strategies needed to support healthier indoor environments. This includes advancing education on indoor environmental quality (IEQ), promoting third-party certification, and supporting research that links design and materials to long-term health outcomes.
A Call to Action
Yes, creating healthier indoor spaces requires sweeping policy shifts and large-scale investments but it begins with awareness, followed by informed choices in materials, ventilation, and maintenance practices.
As we reflect on the goals of National Safety Month, saving lives and preventing harm, it is essential that we include the air we breathe indoors in this mission. Because safety should not stop at the absence of accidents. It must also include the presence of health.
