Regulatory Compliance and Medical Surveillance

Occupational Safety and Health

Whether you need to ensure your workforce is compliant with U.S. Department of Labor Occupational Safety and Health Administration (OSHA) regulations in one state or all 50, we have the ability to handle your needs in the area of workforce medical services.

Comprehensive Health Services conducts medical surveillance exams consistent with OSHA regulations and guidelines and medical best practices. The hazards addressed are identified by the employer (or with our support), and our medical determinations provide you with documentation of regulatory medical surveillance compliance.

The physicians, nurses, and nurse practitioners on our staff ensure that all medical determinations made through our network of health care professionals are consistent and accurate.

Examples include:

  • HAZMAT Exams – These exams involve regular monitoring for anyone who may have been exposed to any hazardous material, above an applicable permissible exposure limit for that material for more than 30 days a year. This also includes members of HAZMAT teams or any individuals who respond to actual or possible leaks or spills of hazardous substances.

  • Hearing Conservation Program Management – These programs are intended to prevent initial occupational hearing loss, preserve and protect remaining hearing, and equip your employees with the knowledge and hearing protection devices necessary to safeguard themselves.

  • Respirator Clearance – Respirators protect workers against insufficient oxygen environments, harmful dust particles, fog, smoke, mist, gases, vapors, and sprays.  We work directly with you to make sure qualified employees obtain respirator clearance, as needed, to maintain safety in their job.

  • Crane Operator – We conduct the physical exams required as part of the crane operator certification process, which include comprehensive physical exams and physical fitness tests, vision exams, hearing exams, and drug testing, among other tests.

  • Asbestos, Lead, Blood Borne Pathogens, and Other Regulated Exams – These exams may involve blood tests or other physical evaluations as required by OSHA.

  • Additional exams that are needed to ensure compliance.

DOT and Other Federal Agency Certification Exams

We conduct a variety of Department of Transportation (DOT) certification exams for our clients. Whether your employee is a commercial driver, railroad worker, public transportation worker or a merchant mariner, safety is of the utmost importance. All of these employees must complete a physical exam to ensure they are healthy enough to safely perform their jobs. Your employee is responsible not only for his/her safety but for the safety of others on the road, rail or water.

The following DOT agencies require certification exams:

  • Federal Motor Carrier Safety Administration
  • Federal Railroad Administration
  • Maritime Administration
  • Federal Transit Administration
  • Federal Aviation Administration

We also facilitate certification exams for the U.S. Coast Guard and Military Sealift Command and agencies such as the Nuclear Regulatory Commission.

Case Study

Seafarers International Union (SIU)


Locations Served: All 50 states in the U.S. and Guam, Saipan, Puerto Rico, Virgin Islands, and the Philippines.

The Client: The Seafarers International Union (SIU) is the largest North American union representing merchant mariners. 

The Need: Among the benefits offered to members of SIU is participation in the Seafarers Health and Benefits Plan (SHBP). When SIU was looking at improving its clinic system as part of that plan, the union needed a company with an extensive network of providers and the ability to handle a rapid surge in volume of exam services in an efficient manner. In particular, SIU wanted to expand the clinic network offered to its members in order to better serve them closer to home.
