Material Safety Data Sheets

Material Safety Data Sheets (MSDS) provide important information on chemicals, chemical compounds and chemical mixtures. MSDS's also provide information on physical data, toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment and spill handling procedures. This is valuable information to both workers and emergency personnel. Below are links to the most common chemicals that are used within the Colusa Unified School District. If you need assistance with locating a specific MSDS for a product please contact our MOT department at 530-458-7791 ext. 14550 or e-mail us at
