Medical Screening and Surveillance Requirements Guide
The Occupational Safety and Health Act requires that employers comply with safety and health standards promulgated by OSHA or by a state with an OSHA approved state plan. This guide is a quick reference to help you locate and implement the screening and surveillance requirements of the Federal OSHA standards published in Title 29 of the Code of Federal Regulations (29 CFR). This guide provides a general overview of OSHA requirements. It is not a standard or regulation, and it creates no new legal obligations. For full details of specific compliance requirements, please consult the appropriate OSHA standard in the CFR. You can access the medical surveillance provisions of the OSHA standards on the Internet at www.osha.gov. Additional assistance is available by telephone at 1-800-321-OSHA (6742).
Select a standard to review medical screening and surveillance requirements.

1 Preplacement and periodic examinations are dependent upon specific factors cited in the standard such as airborne concentrations of the substance and/or years of exposure, biological indices, age of employee, amount of time exposed per year. In addition, some standards require periodic exams to be conducted at varying time intervals. Refer to standard for complete details.
2 Standard requires medical and work history focused on special body systems, symptoms, personal habits, and/or specific family, environmental or occupational history. Refer to standard for complete details.
3 No examination required if previous examination done within specified time frame (e.g., 6 months or 12 months) and provisions of standard met. Refer to standard for details.
4 Additional physician review: Some standards have provisions for referring employees with abnormalities to a specialist as deemed necessary by examiner. Other standards have provisions for multiple physician review. See specific standard for details.
