| Resumen: | This CWA specifies procedures, validation methods, and quantifiable thresholds for the decontamination of persons exposed to CBRN-E agents during a crisis incident. It is intended for use by first responders, first receivers, emergency planners, and public safety organizations to enhance operational effectiveness and international cooperation. The procedures are applicable to both single-person and mass-decontamination scenarios; in mass contamination events, the process can be adapted to the number of persons requiring decontamination and to the resources available.
A CEN Workshop Agreement cannot deal with safety aspects, including aspects of occupational health and safety. Quantifiable thresholds in this document apply exclusively to victims. This document therefore does not specify the PPE to be worn by decontamination personnel; this is to be determined by the responsible organization in accordance with applicable occupational safety and health regulations and a situation-specific hazard assessment [3]. Detailed wastewater management is outside the scope of this document and is addressed under applicable environmental, hazardous-waste, and incident-specific requirements [4].
The document covers:
- Principles of human-centric decontamination;
- Protocols for setting up and managing decontamination zones;
- Specific procedures for chemical, biological, and radiological contaminants;
- A framework for establishing and verifying quantifiable safety thresholds;
- The integration of innovative technologies for real-time field detection;
- Advanced, scenario-based training methodologies for decontamination teams;
- Guidelines for digital documentation, auditing, and continuous improvement. |
