Mask Fitting
A properly fitted face mask provides protection from airborne chemicals, vapours, gases and solid particles (dust, fibers, fine bitumen, metal shavings, etc). At Canada Research Laboratories we determine a proper mask fitting seal with our electronic respiratory testing systems.
Precision Mask Fitting
Mask fitting is a critical health and safety protocol designed to ensure that a respirator forms an airtight seal against the wearer's face. In high-risk environments, a proper fit is essential to guarantee that airborne hazards such as dust, vapors, or pathogens are correctly filtered, preventing them from entering the breathing zone and compromising workplace safety.
Canada Research Laboratories performs advanced quantitative fit testing to provide measurable, objective data on respirator performance. This precision-driven approach ensures maximum accuracy and regulatory compliance, verifying that every seal provides the highest standard of protection for workers across diverse industrial sectors.
Qualitative Fit Testing
Subjective Assessment: Relies on the wearer's ability to detect a safe test agent by taste or smell.
Common Usage: Most suitable for half-mask respirators and disposable N95 masks where a numerical fit factor is not required.
Methodology: Uses specialized aerosols like Bitrex™ or Saccharin within a hood while performing standard movements.
Qualitative vs Quantitative Mask Fitting
Selecting the appropriate fit testing method ensures that your respirators provide the necessary protection level while meeting all safety and regulatory compliance standards.
Quantitative Fit Testing
Objective Analysis: Provides a precise, numerical 'Fit Factor' by measuring actual leakage with electronic sensors.
Common Usage: Mandatory for all full-face respirators and high-hazard environments where absolute precision is critical.
Methodology: Uses Condensation Nuclei Counters to calculate particle concentrations inside and outside the respirator seal.
