Which decontamination type is the planned and systematic process of reducing contamination to a level that is as low as reasonably achievable?

• A. Emergency Decontamination
• B. Gross Decontamination
• C. Technical Decontamination
• D. Mass Decontamination

Answer: (C)

Technical decontamination is the planned and systematic process of reducing contamination to a level that is as low as reasonably achievable. This approach uses a defined sequence, controlled environment, and proper waste management to thoroughly remove contaminants rather than just doing a quick cleanup. It often involves setting up a decontamination corridor, performing a staged process (prewash to remove the bulk, thorough washing and rinsing, and a final verification), and using monitoring to confirm that acceptable contaminant levels have been reached. The goal is to minimize exposure for responders and patients and prevent cross-contamination, even if it takes more time and resources than other methods. In contrast, emergency decontamination is rapid and life-saving, gross decontamination is a quick surface cleanup, and mass decontamination focuses on processing large numbers quickly with less per-person thoroughness.
