When most people think about air quality in industrial environments, their minds go straight to respirable dust—the tiny particles that can make their way deep into the lungs. But there’s another side to the story that often goes unnoticed: Total Particulate Matter (TPM). Understanding and managing TPM is essential to maintaining a safe, compliant, and efficient workplace, especially in Alberta’s diverse industrial sectors, from manufacturing to energy production.
What is Total Particulate Matter?
Total Particulate Matter refers to all solid and liquid airborne particles suspended in the air, regardless of size. While respirable dust focuses on the smallest particles that can penetrate the lungs, TPM includes everything—from larger dust particles you can see floating through light beams to microscopic aerosols invisible to the naked eye.
These particles can come from a variety of sources: metal grinding, cutting, welding fumes, combustion by-products, and even everyday maintenance activities. While larger particles may not be inhaled deeply, they can still cause irritation, contaminate equipment, and contribute to long-term buildup on surfaces and ventilation systems.
In other words, TPM gives a complete picture of air quality, not just what workers are breathing in, but what’s circulating throughout the facility.
Why TPM Monitoring Matters for Industrial Facilities
Monitoring Total Particulate Matter isn’t just about checking another box on a safety checklist—it’s about protecting both people and operations. High levels of airborne particulates can lead to a range of problems. From a health perspective, workers exposed to TPM may experience respiratory irritation, coughing, or allergic reactions. Over time, chronic exposure can worsen respiratory conditions or lead to decreased lung function, even when respirable dust levels appear to be within acceptable limits.
From an operational standpoint, TPM can also impact machinery and infrastructure. Accumulated dust and particulates can clog filters, reduce airflow in HVAC systems, and interfere with sensitive instruments or electronics. This leads to more maintenance, downtime, and unexpected repair costs.
In Alberta, regulatory bodies such as Occupational Health and Safety (OHS) set standards and exposure limits for airborne contaminants. Understanding your facility’s TPM levels helps ensure compliance with these regulations while demonstrating your commitment to employee health and environmental responsibility.

The Link Between TPM, Respirable Dust, and Worker Safety
Think of TPM as the big picture and respirable dust as just one part of it. Respirable dust consists of particles small enough to enter the lungs, typically less than 10 microns in diameter. TPM, on the other hand, includes those fine particles along with larger dust that settles more quickly but still affects workplace cleanliness and air circulation.
Even if respirable dust levels are controlled, high TPM levels may still signal poor ventilation or localized contamination. For example, in manufacturing or fabrication shops, cutting and grinding operations can generate both visible dust and fine particulate matter. Without proper containment or extraction, these airborne materials spread throughout the workspace, increasing exposure risk and lowering overall air quality.
This is why comprehensive air quality testing that includes TPM measurement provides a more accurate and actionable assessment of your facility’s environmental conditions.
Testing and Managing Airborne Particulates in Alberta Workplaces
Professional air quality testing services—like those offered by Ask Environmental—use specialized equipment to measure TPM and identify sources of particulate emissions. By understanding where particles originate and how they move through the workspace, facility managers can make targeted improvements such as upgrading filtration systems, adjusting ventilation, or modifying processes that create excessive dust.
Testing for TPM also supports proactive maintenance and long-term cost savings. Clean air doesn’t just protect workers—it helps machinery run more efficiently, prevents buildup in ductwork, and reduces the frequency of unplanned maintenance.
In Alberta’s industrial landscape, where environmental performance and worker safety go hand in hand, TPM testing is becoming an essential part of responsible operations. Whether you operate in oil and gas, agriculture, or manufacturing, identifying and controlling airborne particulates can help prevent costly issues and keep your business aligned with evolving safety standards.
Take a Proactive Approach to Air Quality
Total Particulate Matter may not get as much attention as respirable dust, but it plays a crucial role in maintaining a healthy and compliant industrial environment. By understanding and monitoring TPM, companies can improve worker safety, protect valuable equipment, and stay ahead of regulatory requirements.
