Contamination Reduction Corridor (CRC)
Decontamination procedures take place in a designated area within the CRZ called the Contamination Reduction Corridor (CRC).
The corridor begins at the Contamination Control Line, spans the width of the CRZ, and ends the Hotline. At least two lines of decontamination stations should be set up within the CRC: one for personnel and one for heavy equipment. A large operation may require more than two lines.
Access Control Points
Access into and out of the CRZ from the Exclusion Zone is through Access Control Points: one each for personnel and equipment entrance, one each for personnel and equipment exit, if feasible.
Access Control Points should be established at the periphery of the Exclusion Zone to regulate the flow of personnel and equipment into and out of the zone and to help verify that proper procedures for entering and exiting are followed.
Contamination Control Line
The boundary between the Support Zone and the CRZ, called the Contamination Control Line, separates the possibly low contamination area from the clean Support Zone.
- Access to the CRZ from the Support Zone is through two Access Control Points if feasible: one each for personnel and equipment.
- Personnel entering the CRZ should be required to wear the personal protective clothing and equipment prescribed for working in the CRZ.
- To reenter the Support Zone, workers should remove any protective clothing and equipment worn in the CRZ, and leave through the personnel exit Access Control Point.
