Runoff Management is a documentation item that applies particularly to which type of training structure?

• A. Purpose-built prop
• B. Acquired structure
• C. Outdoor rest area
• D. Vehicle fire range

Answer: (B)

Runoff management focuses on capturing and controlling the water and combustion byproducts that flow off the burn area so environmental contamination and exposure are prevented. This is especially important for acquired structures because they come with unknown contents and residues—old paints, solvents, household chemicals, furnishings, or even hazardous materials—that can make runoff unpredictable and potentially hazardous. Documenting how runoff will be contained, treated, and disposed of, and who is responsible for ensuring it’s done, is essential when the structure isn’t purpose-built and may introduce unknown contaminants into the drainage. Purpose-built props are designed with known materials and built-in containment, so the need for separate runoff-management documentation is less about the prop type and more about the unknown hazards present in acquired structures.
