What should be done to reduce risk to passengers during a dangerous goods incident?

• A. move pax away and distribute wet towels or cloths
• B. increase cabin lighting
• C. resume cabin service
• D. evacuate immediately

Answer: (A)

The main idea is to minimize passengers’ exposure to hazardous fumes or contact with spilled substances by creating distance from the source and adding a simple protective barrier. Moving passengers away from the area of hazard reduces the concentration of any fumes they might inhale, and giving them damp towels or cloths provides a physical barrier over the nose and mouth. The damp cloths help filter or slow the entry of vapors and offer some cooling and comfort while the crew assesses the situation and determines the safest course of action.

Increasing cabin lighting doesn’t address the danger and can be distracting. Resuming cabin service would bring more movement and exposure without reducing the hazard. Evacuation is a separate, higher-risk step that is only appropriate if there is an immediate, unavoidable danger; until then, moving people away from the source and using damp barriers is the prudent initial action to lower risk.
