Spirometry Training Program

What is a NIOSH-approved spirometry training course?

The Cotton Dust Standard [29 CFR 1910.1043], promulgated by the Occupational Safety and Health Administration (OSHA), gives the National Institute for Occupational Safety and Health (NIOSH) the responsibility to approve spirometry training courses for individuals who administer spirometry tests to employees exposed to cotton dust.

In addition to the Cotton Dust Standard, two other regulations now require NIOSH-approved spirometry training: OSHA’s Respirable Crystalline Silica Standards for general industry and maritime and construction and NIOSH’s Specifications for Medical Examinations of Coal Miners.

Note: Facilities performing spirometry testing on coal miners or coal mine contractors (surface and underground) must apply for Spirometry Facility Approval.

    For example, if you successfully completed a course on April 7, 2016, your final expiration date is:

    5 years + 7 months + 1 year = November 2022

    NOTE: NO extensions beyond the usual 7-month grace period will be given for certificates expiring in 2022.
