Workers are to be stationed in each room/area of the Decontamination Facility to
transfer the containers and equipment to or from adjacent sections. These workers
shall not cross the airlocks into the adjacent areas/rooms until the waste or
equipment transfer is finished for that period and the workers have gone through
decontamination as required by these Specifications. The workers in the Clean
Room or holding area shall enter from uncontaminated areas with appropriate
personal protective equipment; or prior to the start of waste transfer, these
workers shall exit the Work Area, fully decontaminated, and subsequently don
clean personal protective equipment.
External surfaces of contaminated containers and equipment shall be cleaned by
wet cleaning or HEPA vacuuming or both in the Work Area before moving such
items into the Decontamination Facility airlock. Workers shall not enter the
airlock during this procedure.
The containers of waste and the equipment shall be removed from the airlock by
workers stationed in the washroom during waste removal operations.
Once in the Shower Room or wash room, external surfaces of contaminated
containers and equipment shall be cleaned a second time by wet cleaning.
The cleaned containers of waste and equipment shall be placed in uncontaminated
Disposal Bags (or 6-mil sheeting if physical characteristics necessitate and
permit). Air volumes shall be minimized, and the bags or sheeting shall be sealed.
The clean recontainerized items shall be moved into the airlock for subsequent
transfer to the holding area. The Shower Room or wash room workers shall not
enter this airlock or the Work Area until waste removal is finished for the period.
Recontainerized items and cleaned equipment shall be removed from the airlock
to the holding area by workers who have entered from uncontaminated areas with
appropriate personal protective equipment.
The recontainerized items of waste and cleaned, bagged equipment shall be
placed in closed top, watertight plastic carts or drums. These carts or drums shall
be held in the holding area pending removal. The carts or drums shall be HEPA-
vacuumed or wet-cleaned following the removal of the containers of waste from
them.
The exit from the Decontamination Facility shall be monitored and secured at all
times to prevent unauthorized entry.
