During shelter-in-place, citizens should be instructed to do all of the following EXCEPT?

• A. shut all windows and doors
• B. shut off air handling systems
• C. stay tuned to a TV or radio
• D. shut off all electrical appliances

Answer: (D)

During a shelter-in-place situation, the primary goal is to create a barrier between citizens and any hazardous materials outside. Shutting all windows and doors helps prevent contaminated air from entering a building. Turning off air handling systems is crucial as these can bring in outside air, which may be polluted or hazardous, thus compromising the safety of individuals inside. Staying tuned to a TV or radio is essential for receiving updates from emergency services regarding the situation and any instructions that may change as the scenario unfolds.

However, shutting off all electrical appliances is not a necessary measure during shelter-in-place. Most electrical appliances do not present a risk that would justify their disconnection, and in fact, some appliances may be important for communication or other safety needs during an emergency. Therefore, while it may be prudent to avoid unnecessary energy consumption, it is not a standard recommendation during a shelter-in-place procedure, making it the exception among the recommended actions.
