Good FEMA publication. I would like to add to the resources for school safety. Please see the Safe to Learn site http://www.safetolearn.com which stresses Leadership within individual schools if we are ever going to have safe schools. As a former EM, I tried for years to get disaster training life skills in my county schools. (Why not train younger generations how to take care of themselves? Their parents and schools don’t have the skills.) I could work any school I wanted to – every day if I had the time – BUT the school leaders, staff and teachers did not and would not take it upon themselves because it added to their workload. Very disappointing. Until the mindset changes and parents and school leaders choose safety as a priority, the emphasis will remain top down and not bottom up.
