Coal Workers’ Health Surveillance Program

Black Lung Screenings

The Coal Workers’ Health Surveillance Program (CWHSP) is staffed by trained NIOSH personnel who provide screening services to coal miners across the U.S. through state-of-the-art mobile testing units.  Screenings include:

  • Work history questionnaire
  • Chest radiograph
  • Respiratory assessment questionnaire
  • Lung function testing (spirometry)
  • Blood pressure screening

NIOSH directly provides each miner with their screening results. By law, each person’s results are confidential. No individual information is publicly disclosed.

Participation in this program gives coal miners:

  • An easy way of checking their health status
  • A confidential report about their lung function
  • A confidential report on whether or not they have radiographic evidence of black lung

Announcements for times and locations of black lung screenings are posted through NIOSH press releases, the CWHSP Program Facebook page, @NIOSHBreathe Twitter, and the Coal Workers’ Health Surveillance Program webpage. Announcements are also made through local newspapers and radio stations. Further information can be found in our program fact sheet or by calling us at 1-888-480-4042.
