A bag indicator is coupled to at least one of the containment housing or door and is visible, when in a first position, from an exterior of the containment housing when the door substantially covers the bagging ring. In yet another embodiment, a bag for use with a containment housing is provided. The bag has an open end configured to engage with a bagging ring.
