When arresting a suspect known to have tuberculosis, what precaution should the officer take?

Wearing a mask is crucial when arresting a suspect known to have tuberculosis because tuberculosis (TB) is primarily transmitted through airborne particles when an infected person coughs, sneezes, speaks, or breathes. By wearing a mask, the officer can significantly reduce the risk of inhaling the infectious droplet nuclei that might be present in the air.

Furthermore, using a mask is a standard precautionary measure, particularly in close-contact situations where exposure to pathogens can occur. This step is essential for the protection of the officer, ensuring their health and safety while handling a potentially contagious individual.

While other options, such as wearing safety gloves, eye protection, or isolating the suspect, may assist in specific contexts, they do not address the primary transmission method for TB, which is through the air.
