This method assesses the seal of the respirator based on the wearer's ability to detect a test agent, which can either have a sweet taste or a bitter taste.
Unlike quantitative fit testing, the qualitative approach is subjective and based on the user's perception, making it suitable for masks that do not require a tight seal.
Through a series of simple tests, we help identify the right mask and ensure it fits correctly, providing essential protection against particulate matter and harmful substances in the workplace.
This method measures the actual amount of leakage air flow into the facepiece respirators. Irwin's uses PortaCount Fit testing technology that counts particles inside and outside the respirator, calculating a fit factor that indicates how well the respirator fits.
PortaCount provides objective, numerical results, ensuring a more accurate assessment of the respirator’s fit. We will conduct a variety of fit test exercises using this machine such as Normal Breathing, Deep Breathing, Talking Exercise, and others to ensure that no airborne contaminants can enter the respirator filter.
Healthcare Workers (frequent exposure to airborne pathogens, viruses, and hazardous substances)
Emergency Responders and Firefighters (often encounter smoke, toxic fumes, and chemical hazards)
Construction and Demolition Workers (exposed to dust, asbestos, silica, and other harmful particles)
Manufacturing and Industrial Workers (working with chemicals, paints, and solvents, need fit testing to protect against the inhalation of toxic vapors and fumes)
Agricultural Workers (involved in pesticide application, handling fertilizers, and working in environments with high levels of dust and mold)
