Abstract |
Subjective assessments of comfort and efficiency of respiratory protective equipment (RPE) against dust have been carried out in healthy volunteers during standardised inward leakage tests. The results show a clear-cut difference between two RPE classes, facepieces and filters (Pcart) and filtering facepieces (Ppap). Subjectively, Pcart were felt to be more efficient and less comfortable than Ppap. The comparison between subjective and objective efficiency shows that for Pcart subjective estimates have a good correlation with actual efficiency. For Ppap, whatever their measured leakage, subjective efficiency is always estimated as poor. Under the experimental conditions of this study, breathing is only slightly hampered by any RPE. The discomfort of Ppap is related to their reduced field of vision. The strap system is the main discomfort source of Pcart. These results have to be considered for dust RPE selection and user's information in order to improve the protection of workers. |
