How should this healthy entryway be changed to meet the requirements of the standards?

A new retail pharmacy is designing a healthy entryway to achieve Pollution Infiltration Management. The entryway, which is 10 ft. (3 m) long and the width of the entrance, consists of a grating system and rollout mats to effectively reduce the transmission of pollutants. The entryway is vacuumed once a week by the facilities team.

How should this healthy entryway be changed to meet the requirements of the standards?
A . Remove the rollout mats
B . Remove the grating system
C . Increase vacuuming to once a day
D . Increase the length to at least 15 ft. (4.5 m)

Answer: D

Explanation:

To meet the standards for Pollution Infiltration Management, the healthy entryway design in a retail pharmacy should be modified to increase vacuuming frequency to once a day. This adjustment ensures more effective removal of pollutants and particulate matter brought in on shoes and clothing, thus enhancing the entryway’s capability to reduce the transmission of pollutants into the indoor environment.
