About Respiratory Health Division

At a glance

The Respiratory Health Division (RHD) is part of the National Institute for Occupational Safety and Health (NIOSH). RHD conducts research and administers service programs to prevent work-related respiratory disease caused by hazardous occupational agents and to improve workers’ respiratory health.

What we do

Respiratory Research

RHD provides national and international leadership in work-related respiratory health issues by generating new knowledge and transferring that knowledge into practice to benefit workers. The division’s research includes:

  • Conducting multidisciplinary research to identify work-related respiratory hazards, assess workplace exposures, characterize health risks, and develop and disseminate effective interventions.
  • Collecting, analyzing, and disseminating national data to track the burden of work-related respiratory disease.
  • Responding to NIOSH Health Hazard Evaluation (HHE) requests for evaluations of potential respiratory risks and providing recommendations for solutions.
  • Providing health screening and surveillance services to U.S. coal miners under a program mandated by federal law called the Coal Workers’ Health Surveillance Program.

Examples include:

Various areas of studies include exposures to:

Field Studies

Under the NIOSH Health Hazard Evaluation Program, RHD responds to requests from employers, current employees, or their authorized representatives, to conduct on-site investigations of reported respiratory hazards in their workplaces. This work includes evaluation of the frequency and severity of specific respiratory diseases using:

  • Epidemiological methods
  • Environmental assessments
  • Industrial hygiene sampling
  • Medical testing
  • Laboratory research
  • Data analysis

Findings of investigations allow RHD to provide workplaces with appropriate recommendations for prevention. RHD health hazard evaluations have included investigations of:

RHD also performs experimental field studies for investigating relationships between work and respiratory diseases to characterize potentially hazardous exposures and evaluate effectiveness of preventive interventions.

Respiratory Surveillance

RHD studies trends of specific diseases and integrates mortality, morbidity, and hazard surveillance data pertaining to occupational respiratory health and provides scientific findings to diverse audiences. To achieve this, RHD uses data from national health surveys, industry-wide medical monitoring programs, electronic health records, and inspection/enforcement programs.

Coal Workers' Health Surveillance Program

The Coal Workers' Health Surveillance Program (CWHSP) was initially established in 1970 by the Federal Coal Mine Health and Safety Act of 1969. In accordance with the Mine Safety and Health Administration's rule on respirable coal mine dust exposure, the CWHSP provides the following services, below.

Health Screening for Coal Miners: CWHSP provides U.S. coal miners with the opportunity to undergo health screening for respiratory disease with respiratory symptom questionnaires, chest x-rays, and spirometry (a type of lung function test) at entry into coal mining and at intervals thereafter throughout their coal mining careers. Screenings are provided by medical facilities approved by NIOSH and a NIOSH mobile unit that travels to coal mining regions throughout the nation.

NIOSH B Reader Program: The B Reader Program aims to create and maintain a pool of physicians who are able to "classify" chest radiographs for the presence and severity of changes associated with pneumoconiosis (dust-induced lung disease) using the International Labour Organization's classification system. It accomplishes this aim by providing learning opportunities and examinations that document physicians' abilities to use the classification system.

NIOSH Spirometry Training Program

The Occupational Safety and Health Administration (OSHA) Cotton Dust Standard [29 CFR 1910.1043] assigned NIOSH the responsibility of approving spirometry courses developed to train technicians who perform spirometry under the Standard. The purpose of a NIOSH-Approved Course is to improve the quality of testing by assuring that technicians who perform spirometry have received sufficient theoretical and hands-on training. NIOSH-approved spirometry training courses are recognized for their quality and are attended by technicians performing spirometry in a variety of settings.

Technology and product highlights

Dampness and Mold Assessment Tool

Research has found that people who spend time in damp buildings are more likely to report respiratory health problems. This tool can help assess areas of dampness in buildings and schools and prioritize remediation for general buildings and schools.
