What is the setup for Gross Decontamination?

The setup for Gross Decontamination involves using two ladder trucks with fully extended ladders positioned at a 2-degree elevation. This configuration is crucial for effectively managing decontamination operations at hazardous materials incidents or other situations where individuals may need to be thoroughly cleaned of contaminants. The slightly elevated ladders allow for water to flow properly, ensuring that contaminants are washed away effectively without pooling or causing secondary contamination.

This arrangement provides a safe and efficient way for personnel to move through the decontamination process, allowing for simultaneous cleaning and minimizing exposure risks. The use of two ladder trucks instead of one increases the operational capacity, enabling more individuals to be decontaminated at the same time and facilitating a quicker response.

The other options either utilize the incorrect number of ladder trucks, do not structure the ladders appropriately, or do not provide the necessary elevation to ensure that water runoff is managed properly. This makes the choice of two fully extended ladders at a 2-degree elevation an optimal setup for effective gross decontamination.
