Which of the following is NOT one of the three main decontamination types?

• A. Emergency Decon
• B. Mass Decon
• C. Routine Decon
• D. Technical Decon

Answer: (C)

Decontamination in hazmat response is organized into three main types defined by urgency, scale, and level of control: emergency decon, mass decon, and technical decon. Emergency decon is performed on scene as the fastest possible cleansing to stop further spread and to get personnel back into operations quickly. Mass decon uses streamlined, scalable setups to decontaminate a large number of people when many victims or responders are involved. Technical decon is the most thorough option, carried out under controlled conditions with specialized equipment and procedures to achieve deep, thorough decontamination for hazardous materials that require careful handling.

Routine decon does not fit this standard framework; it refers to routine cleaning practices that occur outside an incident response, not the structured decon types used to manage exposure during a HazMat event. Therefore, Routine Decon is not one of the three main decontamination types.
