What Does an Air Quality Test Detect? – Ensuring Safe Workplaces Through Industrial Hygiene
You want to keep your employees safe and healthy at work. But how can you be sure the air quality in your facility isn’t putting them at risk? Even if you can’t see or smell anything unusual, hidden dangers may be lurking.
That’s where industrial hygiene comes in. By testing the air for a wide range of potential contaminants, you can identify and correct issues before they lead to serious health problems or regulatory violations. In this post, we’ll explore what a professional air quality assessment can detect and why it’s a key component of any effective workplace safety program.
Why Air Quality Testing Matters in the Workplace
We all want to believe our workplaces are safe. But the reality is, indoor air quality can often be worse than what’s outside.
Testing the air quality in your workplace on a regular basis helps:
- Protect worker health and well-being by catching issues early
- Identify potential hazards before they cause harm
- Ensure compliance with OSHA, NIOSH, and other regulations
- Boost productivity by providing a safe, comfortable work environment
In industries like manufacturing, construction, healthcare, and energy, air quality testing is especially critical. But really, any type of workplace can benefit from this proactive approach to industrial hygiene.
Common Air Contaminants Detected by Industrial Hygiene Testing
So what exactly are we looking for when we test the air in your workplace? The specific contaminants can vary widely depending on your industry, processes, building materials, and many other factors. But in general, an air quality test will measure levels of:
Chemical Pollutants
Volatile organic compounds (VOCs) are one of the most common types of indoor air pollution. These are chemicals that easily evaporate at room temperature, releasing potentially harmful vapors into the air. Some common sources of VOCs include:
- Solvents used in manufacturing
- Paints, stains, and adhesives
- Cleaning products
- Petroleum-based fuels and lubricants
- New furniture and carpets
Other chemical hazards that industrial hygiene testing can detect include:
- Carbon monoxide from fuel-burning equipment like forklifts or generators
- Formaldehyde from building materials, furniture, and fabrics
- Ozone from printers, copiers, and UV lighting
- Acids, bases, and other process chemicals

Particulate Matter
Solid particles suspended in the air, often too small to see with the naked eye, are another major category of indoor air pollution. These can range from coarse dust you can feel in your nose and throat down to ultra-fine particles that penetrate deep into the lungs. Examples include:
- Dust kicked up by manufacturing processes like sanding, grinding or cutting
- Asbestos fibers from older insulation, flooring, or roofing materials
- Silica dust from concrete, stone, or glasswork
- Fine mists from spraying operations
- Smoke and soot from fires or combustion
Nanoparticles from advanced manufacturing and 3D printing are an emerging concern in some high-tech workplaces as well.
Biological Contaminants
Don’t overlook living organisms as a potential source of poor indoor air quality. An industrial hygiene assessment can determine if your workplace has unsafe levels of:
- Mold spores from leaks, flooding, or high humidity
- Bacteria and viruses from poor cleaning or ventilation
- Dust mites, pollen, and other allergens
- Pest droppings and debris
These biological pollutants can cause allergic reactions, respiratory infections, and in some cases, more serious diseases.
Other Hazards
Some additional air quality hazards an industrial hygienist may look for include:
- Combustible dust from finely ground materials like wood, grain, metals, coal, and plastic. When suspended in the air in the right concentration, these can create an explosion hazard.
- Oxygen-deficient atmospheres can be deadly in confined spaces like tanks, tunnels, or storage bins.
- Extreme temperatures and humidity levels that can cause heat stress in the summer or respiratory issues from dry air in the winter.
The bottom line is that you can’t assume your workplace air is safe just because you don’t notice any obvious problems. Proper air quality testing is the only way to know for sure.

How Cardinal Compliance Consultants Conducts Air Quality Assessments
At Cardinal Compliance Consultants, we follow a proven process to test your air quality and develop customized solutions:
- Discuss your concerns and goals. First, we take the time to listen and understand your unique situation. What prompted your interest in industrial hygiene testing? Have employees been complaining about odors, symptoms, or discomfort? Are you preparing for an upcoming OSHA inspection? Looking to improve operational efficiency and productivity? We’ll discuss your specific needs and how our services can help.
- Thorough on-site inspection. Next, one of our certified industrial hygienists will visit your facility to assess the air quality in person. We’ll identify potential contaminant sources, spot any visible mold or moisture intrusion, evaluate your ventilation systems and PPE usage, etc. We’ll also review your injury records, chemical inventories, and equipment maintenance logs for clues about underlying issues.
- Strategic air sampling. Based on our visual inspection, we’ll develop a targeted air sampling plan to measure key contaminants in the areas of greatest concern.
- We use only the most advanced, calibrated equipment to ensure reliable, accurate results. Our state-of-the-art monitoring technology and testing instruments exceed industry standards, providing you with precise data that supports confident compliance decisions.
- State-of-the-art laboratory analysis. After collecting air samples from your facility, we send them to our network of accredited labs for in-depth analysis. There, skilled scientists will use sophisticated techniques like gas chromatography, mass spectrometry, and microscopy to precisely identify and quantify any contaminants present.
- Clear, actionable reporting. You won’t just get a bunch of numbers and scientific jargon back from us. Our team will carefully analyze the lab results and prepare a clear, easy-to-understand report summarizing the key findings. We’ll compare the measured air quality parameters to OSHA permissible exposure limits (PELs), NIOSH recommended exposure limits (RELs), and other applicable guidelines. If we find any areas of concern, we’ll explain the potential risks and outline some initial steps you should take to resolve them.
- Customized recommendations. Along with our air quality report, you’ll get a detailed list of recommendations tailored to your unique facility and workforce. This may include simple fixes like repairing a ventilation system leak, adding local exhaust to a problem area, or upgrading to more protective respirators. We may also suggest larger-scale solutions like transitioning to less hazardous process chemicals, redesigning work areas to improve airflow, or implementing an employee health surveillance program. We’ll help you understand the pros and cons of each option and develop a practical action plan.
- Ongoing support and follow-up testing. Our industrial hygiene services don’t stop after the initial round of testing. We’ll be there to support you every step of the way as you implement our recommendations. Whether you need help communicating the air sampling results to employees, selecting the right control measures, or conducting follow-up testing to verify the fixes are working, we’ve got your back.
