Final answer:
The CDC requires medical technicians to wear an N95 respirator when working with patients who have active tuberculosis to prevent the transmission of infection.
Step-by-step explanation:
The technician is required by the CDC to wear an N95 respirator when working with patients who have active tuberculosis. An N95 respirator is a type of personal protective equipment (PPE) that is specifically designed to provide respiratory protection against inhalation of dangerous particulates like the Mycobacterium tuberculosis bacteria.
In the context of infectious diseases, particularly airborne transmitted diseases such as tuberculosis, PPE is crucial for the health and safety of medical personnel. The CDC guidelines stress the importance of wearing appropriate protective gear, such as the N95 respirator, to prevent the spread of infection. This type of respirator fits tightly to the face and filters out 95% of airborne particles, significantly reducing the risk of infection transmission. Additionally, other PPE such as protective suits with their own air supply and positive pressure may be used in high-contamination environments such as BSL-4 laboratories. The use of PPE, along with other safety protocols like the proper disposal of gloves, hygiene, and the wearing of safety goggles can help protect healthcare workers from exposure to infectious agents.
