decontamination of critical post

摘要

Mail which may be contaminated with a biotoxin, such as Anthrax, is received in a preliminary sorting area ( 16 ) including a dirty side sorting room ( 40 ) that is sealed to the ambient environment. The mail is loaded into a pass-through decontamination system ( 22 ) in which the mail is sterilized or otherwise decontaminated. The mail is removed from the pass-through system in a second or clean room ( 18 ) which is isolated from the first. The mail is then sorted and processed in the lean room ( 18 ). In the event that the sorting room ( 40 ) becomes contaminated or is suspected of being contaminated by pathogenic biological or chemical agents, a spray system ( 86 ) supplies a decontamination gas into the preliminary sorting area ( 16 ) to decontaminate the dirty side sorting room ( 40 ), any equipment ( 42, 44 ) in the room, and any mail located in the room.
