Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
This question asks for the immediate public health advice for residents following an industrial accident involving the release of airborne toxic chemicals (a toxic plume).
Step 2: Detailed Explanation:
The Concept of Sheltering-in-Place: During an outdoor chemical release, it is often more dangerous to try to evacuate through the toxic cloud than to stay put. The primary life-saving strategy is "Shelter-in-Place".
Essential Protective Actions:
Closing Openings: All windows and doors must be immediately shut to create a barrier between the residents and the toxic air.
Sealing the Environment: Residents should use duct tape, plastic, or even wet towels to seal the cracks under doors and around window frames to prevent the infiltration of gas.
Turning off Ventilation: All air conditioners, heaters, and ventilation systems must be turned off because they actively pull outside air into the building.
Evaluating other options:
Opening windows (C): This is the most dangerous action, as it invites the poison into the home.
Using a mask (D): While useful, standard masks do not filter out many toxic vapors. A sealed building is much more effective.
Step 3: Final Answer:
Sealing all cracks and closing windows to create an airtight shelter is the standard protocol for chemical gas emergencies.
