175. Why is it desirable to have screens on the vents of potable water tanks?
Screens on potable water tank vents prevent insect contamination of the drinking water. Tank vents allow air movement to prevent deformation, but are potential entry points for insects; screens allow airflow while blocking pests. Options regarding explosion prevention, air filtration, and backup prevention are incorrect.
