CO Alarm Sick Parties dispatch consists of which combination?

• A. 2 Engines and 2 Medics
• B. 1 Engine or Aerial and 1 Medic
• C. 1 Engine and 1 Medic
• D. 1 Aerial and 1 Medic

Answer: (B)

CO Alarm Sick Parties are handled with a lean, safety-conscious response that prioritizes quick medical assessment and scene safety. The best pairing is one fire unit (engine or ladder/aerial) plus one medic unit. The engine or aerial provides access, basic fire ground support, and tools for safety and ventilation if needed, while the medic unit delivers patient assessment and potential transport. This combination is flexible enough to fit different scenes—an engine may be perfect for a ground-level call, while an aerial might be needed for upper floors or rooftop access.

Choosing more units, like two engines and two medics, would over-allocate resources for what is typically a lower-risk call. Limiting the response to only an engine or only an aerial would remove the needed flexibility to adapt to the location and safety needs. The combination of a single apparatus (engine or aerial) with a single medic best matches the typical CO alarm sick party response.
