Sheltering-in place is a method of safeguarding people in a hazardous area by keeping them in a safe atmosphere, usually inside structures.

• A. False
• B. It involves evacuation
• C. True
• D. It means sealing all doors but not windows

Answer: (C)

Sheltering-in-place focuses on keeping people inside a building to maintain clean air and reduce exposure during a hazmat incident. The statement is true because the goal is to protect occupants by staying in a safer atmosphere indoors rather than going outside into contaminated air. It’s not about evacuating, which would mean leaving the area. While you may be advised to close doors and windows and minimize outside air entry, sheltering-in-place isn’t simply “seal all doors but not windows”—you follow the guidance given for the situation, which often includes securing openings and, if instructed, adjusting or shutting off ventilation to keep the indoor air as safe as possible.
