Outdated, unknown, or unneeded amounts of dangerous or inappropriate chemicals are often found in K-12 schools across the nation, potentially putting students and staff at risk. Because of the nature of some of the chemicals, even small amounts may present a risk. Thus, dangerous chemicals represent one of the critical environmental health and safety issues schools must address. The Environmental Protection Agency's (EPA) Schools Chemical Cleanout Campaign (SC3) promotes chemical management programs that remove outdated, unknown, or unneeded amounts of dangerous or inappropriate chemicals from K-12 schools. SC3 also promotes the creation of policies and practices that prevent future accumulations of chemicals and encourages responsible management practices of chemicals used in schools. These programs aim to minimize exposure to students and staff, thus improving the learning environment and reducing school days lost. This Workbook provides advice and templates developed by successful SC3 programs in various states, localities, and tribes that can be used to help you design or improve upon your own SC3 program. The tips, techniques, and templates in this Workbook can be applied and adapted for SC3 programs being developed and operated at the school, school district, or state level. Individual chapters contain footnotes. (Contains 28 exhibits and 2 figures.)
