Hazardous Duty Pay Related to Exposure to COVID-19
Questions and answers
No. OPM’s regulations define exposure to “virulent biologicals” as “work with or in
close proximity to . . . [m]aterials of micro-organic nature which when introduced into
the body are likely to cause serious disease or fatality and for which protective devices do
not afford complete protection.” (See Appendix A to subpart I of part 550 of title 5,
Code of Federal Regulations.) Agencies may pay a hazard pay differential to a General
Schedule employee for exposure to “virulent biologicals” only when the risk of exposure
is directly associated with the performance of assigned duties. An employee may not
receive a hazard pay differential under the “virulent biologicals” category if exposure to a
qualifying virus was not triggered by the performance of assigned duties. The hazard pay
differential cannot be paid to an employee who may come in contact with the virus or
another similar virus through incidental exposure to the public or other employees who
are ill rather than being exposed to the virus during the performance of assigned duties
(e.g., as in the case of a poultry handler or health care worker). Also, the virus must be
determined to be likely to cause serious disease or fatality for which protective devices do
not afford complete protection.
Federal Wage System (FWS) employees may not receive an environmental differential for incidental exposure to the pandemic COVID-19. The environmental differential for FWS employees is additional pay for job-related exposure to hazards, physical hardships, or working conditions of an unusually severe nature which cannot be eliminated or significantly reduced by preventive measures. The environmental differential is not intended to compensate employees for exposure to a safety risk unrelated to their assigned duties.
