The phrase indicates a search for local resources that evaluate the seal between an N95 respirator and an individual’s face. This evaluation confirms the respirator’s effectiveness in filtering airborne particles. For instance, someone requiring respiratory protection in a healthcare setting or during wildfire events might use this phrase to locate nearby testing facilities.
Proper respirator fit is crucial for optimal protection. A well-fitted N95 respirator minimizes leakage, reducing the wearer’s exposure to hazardous airborne substances. Historically, ensuring adequate respiratory protection has been a cornerstone of occupational safety, with fit testing becoming increasingly important in various industries and public health contexts.
