Job Roles



Vocabulary Term Definition
absenteeism The absence of an employee or employees. Absenteeism caused by illness during a pandemic should be planned for by employers to ensure continued operation.
acetaminophen An over-the-counter drug used to relieve pain and fever. Acetaminophen can help manage symptoms of COVID-19 when the instructions on the label are followed.
acute respiratory distress A syndrome that develops when the air sacs in the lungs fill up with fluid and restrict the ability of the lungs to take in air. Acute respiratory distress stops the lungs from delivering the oxygen organs in the human body require to function.
allergic reactions A hypersensitive immune response to a substance. Allergic reactions include rashes, swelling, and anaphylaxis and range from mild to severe.
Americans with Disabilities Act ADA. A civil rights law that prohibits discrimination against those with disabilities. The Americans with Disabilities Act prevents discrimination in situations involving employment.
antibody test A test that checks the blood for the presence of proteins that help fight off a viral infection. Antibody tests are used to confirm that someone previously had Coronavirus Disease 2019 (COVID-19) and their immune system successfully suppressed the virus.
asymptomatic Showing no symptoms of disease. Asymptomatic people often do not know they have an illness, since they have no indication that they are ill.
barriers A movable or permanent structure that keeps employees separated. Safety barriers keep employees from spreading respiratory droplets when they cannot practice social distancing.
blood clots A clump of blood cells that have congealed from a liquid to a gel or semi-solid. Blood clots that form in veins or arteries can be life-threatening and require medical treatment.
CDC Centers for Disease Control and Prevention. An agency that develops and applies disease prevention and control, environmental health, and health promotion and education policies. The CDC is part of the Department of Health and Human Services.

cleaning The removal of dirt and impurities, such as germs, from surfaces. Cleaning does not kill germs but does decrease the number of germs on a surface.
cloth face coverings An item of protective clothing that is made from multiple layers of cotton or other tightly woven material and fits snugly over the nose and mouth. Cloth face coverings protect others from diseases the wearer may have.
concentrations The amount of a substance contained within a given amount of space. High concentrations of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can build up in an infected person's upper respiratory tract very quickly.
contaminated Polluted with a noxious substance. Surfaces contaminated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can spread the virus to a person who touches them.
Coronavirus Disease 2019 COVID-19. A respiratory illness caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Coronavirus Disease 2019 was discovered in Wuhan, China in late 2019 and caused the World Health Organization (WHO) to declare a global pandemic in March 2020.
coronaviruses A virus that causes respiratory illness in humans. While mild cases of coronavirus can cause the common cold, more lethal forms of the virus can cause severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and Coronavirus Disease 2019 (COVID-19).
COVID-19 Coronavirus Disease 2019. A respiratory illness caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 was discovered in Wuhan, China in late 2019 and caused the World Health Organization (WHO) to declare a global pandemic in March 2020.
cross-training The practice of training employees on more than one job role or skill. Cross-training allows employees to fill in for absent coworkers, so the work still gets done.
disinfecting The use of chemicals to kill germs on surfaces. Disinfecting does not clean a surface and should be used after cleaning to eliminate remaining germs.

The U.S. federal government agency that carries out federal research, monitoring, standard- setting, and enforcement activities to ensure a clean, healthy environment. The Environmental Protection Agency maintains standards for any fluids that contain potentially harmful ingredients.
face mask Medical grade personal protective equipment that protects healthcare employees from contracting illnesses from patients and vice versa. Face masks have different ratings that indicate the situations in which they should be used.

Food and Drug Administration FDA. A U.S. federal agency that protects public health by ensuring drugs and medical treatments are safe, effective, and truthfully labeled. The Food and Drug Administration has approved three vaccines to protect against COVID-19.
fully vaccinated Having received all necessary doses of a COVID-19 vaccine. Fully vaccinated individuals have immunity two weeks after the last dose of their vaccine.
gloves A type of personal protective equipment worn on the hands and/or arms to reduce the risk of injury. Gloves should always be worn when handling chemicals or sharp objects.
hazard assessment A written, formal appraisal of the safety risks that exist within a workplace. A hazard assessment is often performed by the safety team during a walk-through and is often used to determine appropriate types of personal protective equipment.
