To maintain your school lab, you need to evaluate chemicals on hand, inventory them using safety procedures, and dispose of unwanted chemicals.
Before making decisions on management of science lab chemicals, it is important for school personnel to understand what they have in stock. Conducting an inventory to determine types and quantities of lab chemicals is a good first step. Please remember, old chemicals may be unstable and some chemicals may form explosive compounds as they age. Caution must be used at all times in handling bottles and containers.
After completing an inventory, decisions can then be made on what chemicals are needed and what chemicals should be discarded. All unwanted chemicals must be disposed of properly and in accordance with Montana solid and hazardous waste regulations. For regulatory assistance, please see the Resources tab .
Once lab chemical storage areas have been inventoried and cleaned out, the areas should be properly maintained to avoid future accumulations of hazardous and unwanted chemicals. Guidelines should be developed for chemical storage, purchases, and disposal. Limiting chemical quantities and hazard levels will minimize waste, as well as providing a safe and healthy environment for students and school personnel.
Below are links to information on safely inventorying lab chemicals, a suggested inventory list of lab chemicals, and a link for detailed information about the various chemicals. For your convenience, we’ve provided the chemical list in two formats, Word document or Excel spreadsheet.
