Appendix C. Physical Examination Requirements

Medical surveillance protocols will be used at all Centers (i.e., Centers, Component Facilities, Technical and Service Support Centers, other NASA installations, JPL and Headquarters). This appendix provides examination procedure basics for most routine and specialty examinations performed at Centers. These physical examination requirements are split into six categories, see Table C-1, Examination Categories. Each category addresses specific requirements for physical examinations based on employee responsibilities, workplace environment, exposures, and health maintenance. Hyperlinks are included throughout this appendix for ease of use.

Table C-1. Examination Categories

Examination Category Definition
C.1 Surveillance Examinations for Employees with Specific Potentially Hazardous Exposures Periodic examination for any identified employee designed to detect and monitor potential health effects from a specific hazardous exposure in the workplace to enable early treatment or protective actions.
C.2 Surveillance Examinations for Employees who Work in Hazardous Environments and Workplaces Examinations Periodic examination for any identified employee designed to detect and monitor potential health effects from hazardous exposures or specific occupational conditions to enable early treatment or protective actions.
C.3 Surveillance Examinations for Employees who Require a Certification Periodic examination for any identified employee designed to determine medical qualification for a specified position or duty and the issue of a medical qualification certification.
C.4 Surveillance Examinations for Employees who Participate in Flight Activities Periodic examination for any identified employee designed to determine medical qualification for specified flight duty to ensure safety of flight and mission and the issue of a medical qualification certification.
C.5 Surveillance Examinations for Employees who Require Special Administrative Examinations Periodic examination for any identified employee designed to determine medical qualification for a specified position or duty.
C.6 Surveillance Examinations for Employees who Participate in Voluntary Health Maintenance Periodic examination for any employee who voluntarily opts to participate in health maintenance or preventive health evaluation.
