Evaluation of Coal Mine Dust Personal Sampler Performance.

PB82230178

Publication Date	1973
Personal Author	Doemeny, L. J.; Sorenson, S.
Page Count	96
Abstract	The performance and accuracy of the coal mine dust personal sampler was evaluated. Mechanical properties of the sampler, such as battery life and pump flow meter accuracy, were kept constant. Penetration curves were obtained using monodisperse aerosols of several diameters for three sampling flow rates and three pulsation rates at each flow rate. The effects of particle charge, sampler orientation, air velocity, and mass loading were evaluated using polydisperse coal dust. Results were compared to the respirable mass dust criterion of the Los Alamos (LASL) Atomic Energy Commission, the British Medical council respirable (BMRC) coal dust criterion, and the American Conference of Governmental Industrial Hygienists (ACGIH) criterion.
