• Description:
  Report on the current status of respirator usage and effectiveness in coal mining operations. Topics include field survey of possession and use of respirators, duration of use, job classification, training and maintenance, training programs, respirator maintenance, acceptability of respirators, models used, problems associated with respirator use, breathing difficulties, physical discomforts, suggestions for improvements; determination of respirator effectiveness under field conditions for coal and silica dust; field evaluation of single use respirators; and recommendations. Of three models evaluated, the Welsh model 7165 is considered acceptable by the miners wearing test units. Wearing discomfort and breathing resistance are cited by miners as the major disadvantages of half-mask respirators in general use in bituminous underground coal mining.
