鲁宾说社区需要准备如果居民住所。一些社区的计划“垂直疏散。”In other words, they shelter people in buildings that have been designated safe, like schools or in Irma's case, the Miami-Dade County Fair Expo Center. Public safety officers and other first responders also hunker down in these buildings. "It makes sense to create or designate safe structures," Rubin says. Still, there are emergencies when Rubin says sheltering in place should always be avoided, such as during a野火或危险化学品泄漏,否则除非当局说。
