This paper discusses the importance of a school's having procedures in place to deal with possible biological terrorist threats. It begins with a discussion of biological terrorism. It then provides the symptoms of anthrax, treatment options for anthrax, and precautions to take when suspicious of an attack with a hazardous material. The paper goes on to describe a case study in which a high school student placed packets of baking powder in the lockers of other students who had taunted and bullied him. The baking powder was suspected to be a hazardous material, which caused a crisis situation in the school. The paper concludes by stating the school culture must reflect a daily consciousness and preparedness for extreme circumstances. By preparing for the unexpected crisis and providing routine practice of potential crisis scenarios, students and staff will develop confidence in their ability to respond appropriately and effectively in a crisis situation. (Contains 19 references and a flow chart illustrating procedures to be followed when the presence of hazardous materials creates a crisis in a school.) (WFA)
