What is the setup for Gross Decontamination?

The correct setup for Gross Decontamination involves using two ladder trucks with fully extended ladders that are positioned at a 2-degree elevation. This specific configuration allows for an effective decontamination process by creating an overhead water mist or spray that can wash off contaminants from personnel and equipment. The 2-degree elevation ensures that water can flow and cover a broad area, maximizing the efficiency of rinsing off hazardous materials while providing sufficient coverage.

Using two trucks in this manner also enhances safety and accessibility by allowing for a coordinated response. This setup is designed to effectively manage large-scale incidents where multiple individuals may need decontamination simultaneously. The elevated ladders also provide a vantage point for operators, allowing them to observe and manage the decontamination process effectively.

In contrast, other options do not meet the requirements for effective gross decontamination due to either insufficient elevation or the number of trucks involved, which could limit the process's efficiency and effectiveness.
