There may be instances where staying put, known as “sheltering-in-place”, may be safer than evacuation. In such cases, a shelter-in-place order may direct individuals to remain indoors or seek refuge in a secure location until the danger has passed.
Emergency situations where sheltering-in-place may be required include hazardous material spills, acts of violence, and other emergencies where it is safer to remain indoors until the threat passes. The frequency of shelter-in-place events can vary depending on the location and type of emergency. In some areas, such as regions prone to natural disasters, shelter-in-place may occur several times a year. In other areas, such as low-risk communities, it may only occur occasionally.
