  1. Science Safety:Managing Chemicalsin the Elementary Classroom

  2. Key Question How should I identify and manage chemicals for use in the elementary classroom?

  3. Caution • The use of chemicals in the elementary science classroom should be very limited • If any items are used, only household items should be used • All chemicals, including household chemicals, must have MSDS sheets present

  4. Purchasing Chemicals • Before purchase, consult the MSDS and your administration for each chemical • www.msdsonline.com • MSDS sheets must be kept on file and easily accessible

  5. Generic Chemicals Whenever possible, use generic chemicals. Some examples include: • Vinegar (acetic acid) • Aluminum Foil (aluminum metal) • Vitamin C Tablets (ascorbic acid) • Ammonia (ammonium hydroxide, base) • Chalk (calcium carbonate) • Lime (calcium oxide, basic) • Plaster of Paris (calcium sulfate) • Rubbing Alcohol (isopropyl alcohol) • Talc (magnesium silicate) • Baking Soda (sodium bicarbonate) • Table Salt (sodium chloride) • Table Sugar (generally sucrose) • Epsom Salts (Magnesium sulfate) • Starch (corn starch)

  6. Inventory • Limit the quantity of chemicals purchased to what can be used in a short period of time • Store chemicals (even generic chemicals) in an area that is not accessible to students

  7. Labeling Chemicals • Indicate the name of the chemical manufacturer or supplier (with address and phone number) • Include the chemical name/trade name on the label • Record the date the chemical was received • Include the appropriate hazard symbol of the NFPA rating • Indicate the strength • Give and highlight emergency/first aid directions

  8. Storing Chemicals • Separate, locked storage (preferably away from the classroom) • Use appropriate NFPA warning symbols • Maintain a complete inventory • Keep copies of the inventory and MSDS sheets in the storage area with copies to administration and science safety contact • Dispose of chemicals properly (contact Dusty Rhodes or district safety officer)

  9. Sign School Safety Roster • Be sure to understand each of the previous items • Sign the Roster attesting your understanding

  10. Reflection Questions • How do the topics in this presentation impact your classroom? • What is one best practice that relates to this topic that you would share with colleagues or our staff?
