Contamination Control Area - Airlock - Toxic Free Area Process Analysis (BRIEFING CHARTS)
Abstract
Collective Protection (COLPRO) systems provide unencumbered, long term personnel protection and have capability for ingress/egress of personnel as they process out (doff) and into (donn) Individual Protection Equipment (IPE). To enter COLPRO systems, strict processes are enforced to allow safe entry as well as maintain the integrity of the Toxic Free Area (TFA). Normally, personnel would process through an outside Contamination Control Area (CCA) where decontamination crews identify any gross liquid contamination and direct decontamination appropriately. Personnel then carefully remove their outer protective garments, with the exception of the mask, hood, and gloves and enter the protected entrance or Airlock (A). While in the airlock, air purging removes airborne vapor and aerosol contamination, and personnel conduct the final decontamination steps to clean or contain mask, hood, and gloves. This process of moving personnel through a CCA, Airlock, and into a Toxic Free Area will be referred to as the CCA/A/TFA Process. The objective of this CCA/A/TFA Process Analysis is to analyze current procedures, develop a CCA/A/TFA Process model, and make recommendations to provide personnel an "acceptable level of protection" (contamination level below contamination control limits ) over a specified time interval while maintaining a "throughput" (personnel processed per time interval) sufficient to meet mission/force protection requirements.
