The haphazard storing and tracking of chemicals in the laboratory is a serious safety issue facing science teachers. To get control of your chemicals, try implementing a "chemical tracking system". A chemical tracking system (CTS) is a database of chemicals used in the laboratory. If implemented correctly, a CTS will reduce purchasing costs, eliminate overstocking, and reduce disposal costs. It will also allow you to respond more effectively to accidents, fires, and other hazardous situations. (Contains a list of 5 online resources.)
