A Contamination Reduction Zone (CRZ) is a designated area in hazardous material response operations where personnel and equipment can be decontaminated to prevent the spread of contaminants. It serves as a buffer between contaminated sites and clean areas, often incorporating procedures for removing or minimizing exposure to harmful substances. Typically, the CRZ includes stations for washing, removing protective gear, and proper disposal of contaminated materials. Implementing a CRZ is crucial for maintaining safety and protecting public health during environmental cleanup efforts.

The area immediately surrounding a hazardous material incident is known as the "hot zone," which is the area where contamination is present and poses a risk. Surrounding the hot zone is the "warm zone," which serves as a transitional area where decontamination occurs and personnel can safely monitor for contamination. Beyond the warm zone is the "cold zone," where no contamination is expected, and emergency responders can operate safely to manage the incident without exposure to hazardous materials. These zones are crucial for ensuring the safety of responders and the public.
Decontamination is typically conducted in the warm zone, which is the area between the hot zone (where contamination is present) and the cold zone (where no contamination exists). This zone allows for safe management of contaminated individuals or materials while minimizing the risk of spreading contaminants. Proper protocols and equipment are essential to ensure effective decontamination processes in this area.

To me, the most difficult aspect is keeping the work zone free of DNA contamination. Even a tiny bit of contamination in the polymerization can screw up thousands of tests.
