At Central Laboratories Ltd , we prioritize workplace safety and respiratory protection. Our Mask Fit Testing service ensures that tight-fitting respirators provide the necessary protection for workers in high-risk environments.

What is Mask Fit Testing?

Mask Fit Testing is a mandatory procedure that verifies whether a specific make, model, and size of a respirator properly fits the wearer’s face. It ensures there are no leaks and that the mask forms a secure seal—critical for protection against airborne contaminants, infectious agents, and hazardous materials.

There are two types of fit testing:

• Qualitative Fit Testing (QLFT): A pass/fail test based on the wearer’s sense of taste or smell

• Quantitative Fit Testing (QNFT): Uses specialized equipment to measure actual leakage

Who Needs Mask Fit Testing?

• Healthcare workers

• Construction and industrial staff

• Laboratory personnel

• Anyone required to wear a tight-fitting respirator for work
