Which signs indicate a potential fuel spill near storm drains?

• A. Fuel odor only.
• B. No signs at all.
• C. Sheen or color in water only.
• D. Fuel odor, sheen or color in water, and visible fuel on surface or ground near drainage.

Answer: (D)

Recognizing multiple indicators of a fuel spill near storm drains is essential. When there’s a spill, you may notice several signs, not just one. A fuel odor signals volatile hydrocarbons present in the area. A sheen on the water surface indicates a petroleum layer spreading on the liquid, which can happen even if the odor isn’t strong. A color change in the water can point to contamination, sometimes from dyed fuels or other hydrocarbons. And seeing actual fuel on the surface or on the ground near a drainage inlet is a clear, direct sign that a spill is occurring or has occurred. Because spills can present in any combination of these cues, the most comprehensive and reliable indication is to observe all of them together—odor, sheen or color in water, and visible fuel near drainage. The other scenarios miss one or more signs and could delay identifying a spill or triggering the proper response. If you observe any of these signs, treat it as a potential spill and follow your facility’s spill-reporting and containment procedures immediately.
