This is a great resource for deciding when to evacuate and when to shelter in place, and it can easily be customized for use at your library. Post it to inform patrons and staff, and also use it as a tool for carrying out drills with your public services staff. (Check with your safety officials first to ensure that it complies with their procedures.) Kudos to the staff at the University of Virginia Office of Emergency Preparedness for putting it together.
