WHAT MAKES A GOOD SHELTER?

摘要

Whichever space you choose should have a minimal number of windows (preferably none) and doors. Make sure it offers the opportunity to shut off outdoor air exchange, at least for a short period of time, explains Scott Tezak, practice lead for security and emergency preparedness at TRC Companies Inc., a national engineering, consulting, and construction management firm. If necessary, choose several rooms to avoid overcrowding, such as large storage closets, utility rooms, pantries, copy areas, and conference rooms without exterior windows. Do not shelter in rooms with mechanical equipment - you may not be able to seal these areas from the outdoors very well. Chemical or radiological releases may necessitate a backup plan, warns the Centers for Disease Control & Prevention (CDC). Rooms above ground level are best for chemical spills because some chemicals are heavier than air and could sink. However, a release of radioactive particles would make a centrally located room or basement the better option. "Access to bathrooms is a plus," the CDC notes.
