Which dispatch code corresponds to a hazmat incident involving a mercury spill?

• A. Mass Decon Response - UK Commonwealth Stadium
• B. Hazmat - Mercury Spill
• C. Missing Person
• D. Lock In / Lock Out

Answer: (B)

Selecting the right dispatch code hinges on recognizing hazmat involvement and naming the material when known. Mercury is a toxic heavy metal that requires specialized hazmat response, containment, and decontamination procedures. The code that directly states Hazmat - Mercury Spill signals responders to bring hazmat PPE, air monitoring, spill containment kits, and decon setup, and to implement isolation of the area, which is exactly what a mercury spill demands. Other codes do not fit: a mass decon response is aimed at large-scale decontamination operations, not a single material spill; missing person is unrelated to hazardous materials; lock in / lock out concerns securing access or equipment and does not involve hazardous materials.
