  3. RESPIRABLE DUST TRAINING PROGRAM Section 11 COAL MINE DUST SAMPLING PROCEDURES

  4. Monitoring Exposure And Health • Monitoring Includes: • Monitoring dust levels in the mine workings and in the miner’s breathing zone • Monitoring the health status of the miner population

  5. Reasons for Monitoring • To knowthe level of the contaminant in the mine environment • To know the level of the contaminant in the miner’s breathing zone • To determine the effectiveness of the dust control measures • To fulfill the requirements of the Mine Act for compliance • To know the effectiveness of disease prevention and intervention programs

  6. Elements of a Monitoring Program • The Program has several elements: • Operator’s Sampling Program • MSHA’s Sampling Program, and Part 90 Sampling Program • Ad Hoc and or Additional MSHA Sampling may be done under Section 103[g] of the Act

  7. Approved Sampling Equipment • Sampling must be done using approved equipment. The approved personal dust sampler consists of: • a sampling pump • a filter cassette • a sampling head assembly with a cyclone • tubing and clips • Testing and approval of coal mine dust personal sampler units are covered in 30 CFR 74.

  8. Operator Sampling Requirements • The Operator sampling program requirements are specified in 30 CFR, Part 70, Subpart C. • Operators are responsible for collecting the following types of dust samples: • Designated Occupational [DO] samples • Designated Area [DA] samples • Part 90 miner samples

  9. MSHA Sampling Program Details • The MSHA sampling program is described in the MSHA Policy Manual • The MSHA program also includes DO and DA samples • MSHA also designates certain work locations on the surface for sampling purposes as Designated Work Positions [DWP]

  10. Learn about the dust sampling procedures at your mine! • When? • Where? • Why? • Results?
