4. Goals of Medical Surveillance  Goals of Medical Surveillance include:  Early identification of evidence of disease  Definition of the magnitude and distribution of disease among the miners  Tracking trends in the magnitude of the problem  Targeting mines and sections of mines that require increase attention to exposure control  Public dissemination of information

5.  Results of Medical Surveillance leads to:  New opportunities for prevention  Assess effectiveness of preventive actions  Appropriate policy decisions Results of Medical Surveillance

6. Miner participation is essential for the success of the Medical Surveillance Program!

7. Coal Workers’ X-Ray Surveillance Program  An initial X-Ray within six months of beginning employment  Another chest X-Ray three years after the initial examination  A third chest X-Ray two years following the second one if a miner is still engaged in coal mining and if the second X-Ray shows evidence of category I or higher CWP according to ILO classification

8.  Mine operators are required to offer periodic, voluntary chest X-Ray to miners approximately every five years.  The Mine Act requires that chest X-Rays are to be supplemented by “such other tests as Secretary of HHS deems necessary.”  30 CFR Part 90 - Any miner who shows evidence of the development of pneumoconiosis based on chest X-Ray or other medical examinations has the option to work in a low dust environment in the mine [ambient dust concentration < 1 mg/m 3 Coal Workers’ X-Ray Surveillance Program [Continued]
