When responding to a flammable liquid spill, where should the fire apparatus be positioned relative to the spill?

• A. Uphill and downwind
• B. Downhill and downwind
• C. Uphill and upwind
• D. Downhill and upwind

Answer: (A)

Positioning the fire apparatus to take advantage of both terrain and wind helps keep you and your equipment safer during a flammable liquid spill. Being uphill uses gravity to make runoff and spilled liquid flow away from the vehicle, hoses, and engine compartments, reducing the chance that the liquid will reach or contaminate the apparatus. At the same time, being downwind means the prevailing air flow can carry any flammable vapors away from the vehicle and crew, helping to prevent vapor buildup near you and the equipment. This setup uses natural slope and wind direction to minimize exposure to both liquid and vapors. If wind or conditions change, adjust your position accordingly to maintain the same protective effect.
