Active Cleanroom Construction
Level 3 is for finishing details and is the most restrictive. It includes all the precautions of Level 2, plus several additional steps. Workers must use a designated smock room and have limited access at this stage. Before entering the cleanroom, workers must be fully smocked, including wearing lab coats or coveralls, hair/beard nets, booties and gloves and mask. The recirculation air system should also be employed to continuously clean the air.
