Abstract
Embodiments of the invention generally include a contamination housing assembly and bag for use therein. In one embodiment, a contamination housing assembly includes a housing having an inlet, outlet, and access port. A bagging ring is coupled to the housing and circumscribes the port. A door is provided for covering the port. 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. The bag includes at least one of a strap or a RF readable tag.
