after the Columbine shootings, I was on our school's committee to re-write our emergency management plan...at the time we addressed the problem by purchasing roll and bandage Kerlix, petroleum gauze, gauze pads, abdominal pads, tampons, chem lights, EMT scissors,self adherent and stretch tape in enough amount to outfit 4 Sterilite containers that were pre-positioned around the facility... at the time our RN on staff was against the idea of tourniquets

I had a couple of Israeli dressings and a couple of chem lights in a drawer in my desk, but not nearly enough for a mass event...
