Test of air tightness of 9 FFP2 masks on 50 healthcare workers
If the respiratory mask does not adhere well to an individual's face, its effectiveness against aerosols is compromised, even if its performance has been tested and complies with standard EN 149: 2001.
The fit-test is a mode of operation allowing to check the tightness of a respiratory protection mask on an individual:
-Qualitatively: test based on the perception of a sweet or sour taste through the respiratory mask while performing some exercises. Any leakage on the face is revealed by the perception of taste.
-Quantitatively: test measuring the concentration of particles inside and outside the respiratory mask while performing some exercises. Any leakage on the face is revealed by an increase in the concentration of particles inside the respiratory mask.
Measurement of the rate of effectiveness of the air tightness of masks according to the morphology of the face
The NHS professional bodies, experts and unions have warned that the lives of health care workers are in danger as personal protective equipment is designed for men.
A critical care nurse found that half of the women in her unit failed the fit test
