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?
