Screening and surveillance. OSHA's medical surveillance provisions

The OSH Act requires OSHA to include provisions for medical examinations of employees in its standards. However, the specific test and examinations criteria are not outlined in the OSH Act. Instead, each standard has specific medical surveillance requirements. These are specific to the adverse health effects triggered by exposure to the hazardous substance. The OSHA uses the term medical surveillance to refer to its employee examination and testing provisions. Most occupational health professionals call this activity employee screening and reserve the term surveillance for aggregate analysis of population data. It is important to remember this distinction when referring to OSHA standards. Many standards are challenged in court resulting in changes to medical surveillance provisions of the standards. Some court decisions support OSHA's language. In either case, the court often sets precedents for future standards.
