The mission of the Office of Occupational Medicine (OOM) is to provide medical, toxicological, and epidemiologic expertise to enable OSHA to ensure that every working man and woman in the U.S. has a safe and healthful workplace. To this end, OOM provides assistance to OSHA compliance and enforcement activities, policy and standards development, and agency outreach programs. In addition, OOM provides occupational health information to employers, workers, unions, health professionals, and members of the general public.


OOM is staffed by a variety of healthcare professionals including five physicians. All current OOM physicians are board-certified in Occupational and Environmental Medicine and all have residency training or board certification in additional specialties, including Family Practice, and Clinical Pharmacology. They serve in leadership positions in professional organizations and represent OSHA in a variety of interagency settings. OOM personnel provide medical expertise to the Agency and administer several of the Agency's internal programs (OSHA's Medical Examination Program and Access to Employee Medical Records Program).


Enforcement Support: The most important function of the Office of Occupational Medicine is to assist in OSHA workplace investigations. OOM physicians provide case evaluation, medical record review, conduct employee interviews and medical screening activities in support of work site inspection activities. OOM physicians provide expert opinions regarding whether injuries illnesses and fatalities are related to work. They also determine whether employers are in compliance with medical surveillance and recordkeeping requirements of OSHA standards and regulations. OOM may assist OSHA area offices and the Department of Labor Solicitors (attorneys) in decisions regarding settlement agreements and other legal proceedings. Additionally, OOM staff members contribute to the creation of OSHA national emphasis programs that focus inspection activities to target hazardous industries and exposures.

OSHA Standard Setting: OOM physicians contribute to the development of Agency standards by providing expertise on health effects of occupational exposures and recommendations for appropriate medical surveillance. Standards currently on the regulatory agenda include silica, beryllium, infectious diseases, and illness and injury prevention programs.

Disaster Response/Federal Disaster Response: OOM physicians provide expertise in occupational and environmental medicine to support OSHA as it fulfills its role in the National Response Framework. As part of the Agency’s federal disaster response, OOM coordinated the development and distribution of Psychological First Aid and Resilience Resources targeted to support federal and federalized disaster response workers in hurricane-affected areas.

Influenza Pandemic Preparedness and Response: OOM physicians provide medical expertise to OSHA, the Department of Labor, and the federal interagency community regarding pandemic influenza issues. OOM developed guidance on workplace safety and health strategies and equipment that protect healthcare workers in the event of an influenza pandemic: Pandemic Influenza Preparedness and Response Guidance for Healthcare Workers and Healthcare Employers.

Compliance Assistance and Guidance: OOM participates in the development of OSHA compliance assistance information that helps employers comply with OSHA legal requirements. OM also creates guidance materials that provide information on best practices in workplace safety and health. These informational materials include safety and health information bulletins, fact sheets, quick cards, web-based information and web-pages on OSHA's website. Specific documents developed by OOM include the following:

OOM also participates in alliances and educational activities with organizations such as the American Red Cross, the American Heart Association, the American College of Occupational and Environmental Medicine, the Association of Occupational and Environmental Clinics, the American Public Health Association, the Joint Commission, the Council of State and Territorial Epidemiologists, and others.

Vulnerable Working Populations: OOM assists OSHA in its mission to reach vulnerable working populations by facilitating outreach through public health and community health center venues, collaborating with frontline worker organizations, and representing the Agency in outreach activities addressing the needs of the aging workforce, agricultural workers, service workers, and others to reduce occupational health disparities.

OSHA Occupational Medicine Elective

The Office of Occupational Medicine (OOM) in OSHA serves as an instructional site for resident physicians who are receiving training in occupational and environmental medicine, general preventive medicine, toxicology, and aerospace medicine. At any time throughout the year, the Office of Occupational Medicine may host up to four resident physicians for two-month training rotations. Future occupational and preventive medicine leaders have the opportunity to fully participate in OOM activities and also receive an organized series of lectures on toxicology, homeland security, and clinical occupational medicine. OOM staff members have participated on Residency Advisory Committees for the Uniformed Services University of the Health Sciences and the John Hopkins Bloomberg School of Public Health. For more information on the OOM Medical Residency Training Program, please go to OSHA Occupational Medicine Elective or contact Kathleen Fagan.

Training and Education: OOM physicians are dedicated to excellence in medicine and in teaching and are actively involved in the education of resident physicians and health and safety professionals. The Office participates in the following training efforts:

Educational Conferences

Dr. Kay Dellinger with Dr. Heather Lampel, University of Pittsburgh, Dr. Illy Dominitz, Johns Hopkins, & Dr. Bill Otto, USUHS.

OOM physicians participate in international, national, state, and local conferences such as the American Occupational Health Conference (AOHC), the American Industrial Hygiene Conference and Expo (AIHce), many Joint Commission Resources conferences, including annual meetings on Emergency Preparedness, Patient Safety and Infection Control, and the National Safety Council.

OOM physicians helped to develop the 2010 Secretary's National Summit for Latino Worker Safety and Health and have provided outreach information on occupational aspect of environmental and social justice at meetings of American Public Health Association, the Association of Clinicians for the Underserved, and with federal and state agencies.

OOM provides training to OSHA field staff and others through the OSHA Training Institute. Training topics include workplace medical surveillance, laboratory hazards, biohazards, bloodborne pathogens and emergency response.

OOM frequently coordinates efforts regarding occupational safety and health issues with agencies such as the Department of Homeland Security, the Department of Health and Human Services, including Centers for Disease Control and Prevention and the Food and Drug Administration. The Office has a particularly close relationship with the National Institute for Occupational Safety and Health/CDC, the sister agency created by the Occupational Safety and Health Act. OOM works with NIOSH to facilitate interagency communication through monthly seminars and telephone conferences, and provides members to NIOSH National Occupational Research Agenda (NORA) Sector Councils, the NIOSH Hazardous Drugs Working Group, emergency preparedness activities and various planning activities related to high-risk, low-wage underserved occupational populations. OOM helps to coordinate joint publications between OSHA and NIOSH, including:
