      <subfield code="a">Many different types of surface mining equipment use enclosed cabs to protect equipment health and safety hazards. The overburden removal and mining process can be extremely dusty and can cause excessive dust exposure. To study this issue, a cooperative research effort was established between the National Institute for Occupational Safety and Health, U. S. Silica Co., Clean Air Filter Co., and Red Dot Corp. in an affort to lower respirable dust levels in a enclosed cab on an older surface drill at a silica sand operation</subfield>
