Final answer:
EMTs should routinely wear a mask when treating patients with contagious respiratory illnesses or airborne diseases. This includes situations like a COVID-19 pandemic or poor air quality. Wearing masks helps protect both the EMTs and the patients.
Step-by-step explanation:
EMTs should routinely wear a mask when treating patients with contagious respiratory illnesses or airborne diseases. Masks serve as a protective barrier, preventing EMTs from inhaling harmful pathogens and reducing the risk of transmission to themselves and others.
For example, during a COVID-19 pandemic, EMTs are required to wear masks when treating patients suspected or confirmed to have the virus. This helps to minimize the spread of the virus and protect both the EMTs and the patients.
Additionally, EMTs may wear masks when responding to situations where there is poor air quality or potential exposure to hazardous chemicals or pollutants.
