What is a primary characteristic of gross decontamination?

A primary characteristic of gross decontamination is that it occurs immediately on-site. This is crucial in emergency situations involving hazardous materials, as it aims to quickly remove contaminants from individuals or equipment to prevent further exposure and reduce the risk of spreading hazardous substances. Gross decontamination typically involves the use of water or other methods to wash away the majority of contaminants as a first response, ensuring that those affected can be rapidly treated and kept safe.

This immediate action contrasts with other forms of decontamination, which may require specialized equipment or take place in controlled environments. Technical decontamination is a more thorough process that happens after gross decontamination and typically is conducted in a designated area with the proper facilities to handle hazardous substances safely.
