Where are biohazardous infectious materials most commonly found?

Biohazardous infectious materials are primarily associated with medical and health care facilities due to the nature of the work performed in these environments. In such facilities, there are numerous procedures that involve working with human blood, bodily fluids, tissues, and other potentially infectious materials. This could include hospitals, clinics, and laboratories where patient care and diagnostic testing occur. The protocols for handling, storing, and disposing of these materials are strictly regulated to prevent contamination and protect the health of workers and the public.

While research laboratories also deal with biohazardous materials, the question focuses on the most common settings, making medical and health care facilities the more prominent location. Manufacturing plants and construction sites, on the other hand, do not generally involve biohazardous materials, as they are more focused on industrial processes or building activities, respectively.
