Which decontamination approach uses specialized equipment and longer procedures for thorough cleaning?

• A. Gross decontamination
• B. Minimal decontamination
• C. Technical decontamination
• D. Immediate decontamination

Answer: (C)

Technical decontamination uses specialized equipment and longer procedures to achieve a thorough cleaning. This approach is carried out in controlled, step-by-step ways with trained personnel and tools designed for complete contaminant removal and to prevent cross-contamination. It often involves containment measures, decon chambers or tents, calibrated monitoring devices, and extended procedures to ensure every trace of hazardous material is addressed. This is necessary when substances are persistent, highly hazardous, or require meticulous cleansing beyond quick on-site methods.

Other approaches vary in speed and scope. Gross decontamination aims for rapid, large-area cleaning but isn’t as thorough or controlled. Minimal decontamination provides basic cleaning with limited resources and time. Immediate decontamination happens right away on the scene to reduce exposure, prioritizing speed over comprehensive cleansing.
