Code 80D describes a gas leak involving which fuel?

• A. Gas Leak - Diesel
• B. Gas Leak - Chlorine
• C. Gas Leak - Gasoline
• D. Gas Leak - Hazmat

Answer: (A)

Code 80D is used for a gas leak involving a diesel fuel. The idea behind these codes is to label leaks by the specific fuel involved, so responders know the properties they’re dealing with. Diesel is a liquid fuel, but it can release flammable vapors, which is why it’s addressed under a “gas leak” classification for hazmat response. The other options point to different substances with distinct hazard profiles: chlorine is a toxic gas that would be coded differently, gasoline is highly volatile and would fall under its own fuel-specific leak code, and Hazmat is too generic for the situation. The key takeaway is that the label links the leak to diesel fuel, guiding appropriate precautions and response actions.
