Which dispatch code is used for a natural gas release from geothermal sources or a water well?

• A. Investigation
• B. Mailbox Fire
• C. Hazmat - Natural Gas From Geothermal/Water Well
• D. Large Animal Rescue

Answer: (C)

The key idea is recognizing when a gas release qualifies as a hazardous materials incident that calls for hazmat resources. A natural gas release from geothermal sources or a water well is a hazardous material situation, so using a hazmat code specifically labeled for Natural Gas From Geothermal/Water Well signals responders to expect a gas hazard and to deploy hazmat protocols and specialized equipment. This distinguishes it from more general or unrelated codes. The other options don’t fit because an investigation is for information gathering with no identified immediate hazard, a mailbox fire is a targeted structure fire at a mailbox, and large animal rescue is about rescuing animals—none of which address a gas release hazard.
