In the COLDS acronym used for smoke or fire in the cabin, what does the letter O stand for?

• A. Odor
• B. Color
• C. Location
• D. Density

Answer: (A)

O stands for Odor. This cue is tested to show how sensory information helps crews assess smoke or fire in the cabin. Odor is valuable because the smell of burning materials can reveal that a fire is present and often hints at what’s burning, which guides quick, appropriate actions. While color and density describe how the smoke looks and behaves, and location helps pinpoint the source, odor provides a qualitative clue that can confirm a fire even when visibility is limited.
