Dust masks for Indian quarry workers: A comparative analysis of the filtering efficiency of fabrics
The filtration properties of Indian fabrics were measured using modified respiratory protective device (RPD) tests, to match conditions in Indian quarries. Results were compared to those of dust masks meeting Australian and International standards. Four layers of loose weave fabrics were found to perform best, but would still be insufficient for use at sites with highly hazardous dusts.
