What are the two steps involved in technical decontamination?

The correct answer relates to the process of technical decontamination, which consists of two key steps: gross decontamination and secondary decontamination. Gross decontamination is the initial, rapid removal of contaminants from a person or equipment, typically using methods like water or a decontamination solution to wash away gross contamination. This step is essential for quickly reducing the potential for exposure and further contamination.

After gross decontamination, secondary decontamination takes place, which is more thorough and often involves more detailed and controlled procedures to ensure that any remaining contaminants are effectively removed. This second step typically includes more advanced techniques such as the use of specific decontaminants, scrubbing, or other methods tailored to the type of hazardous material involved.

This two-step approach is critical in emergency response situations involving hazardous materials, ensuring that personnel and equipment are adequately decontaminated to prevent harm and limit exposure. Thus, understanding the distinction between gross and secondary decontamination is vital for effective hazardous materials management.
