  1. Safety in the Laboratory

  2. Ben and his “Lab” Tricks… Video: Ben the Talking Dog • What is he doing wrong??

  3. Do You Have Some Suggestions?

  4. Clothing Protection: • Wear a lab apron to protect clothing from stains and spills. • Always confine loose clothing and hair ex. Roll up long sleeves, tie back long hair • No dangling jewellery • Wear close-toed shoes- no sandals! • Wear gloves • Put away your cell phone

  5. Eye Safety: • Always wear safety goggles. • If anything gets in your eyes, flush them with plenty of water for 15 minutes and let the teacher know immediately. • Be sure you know how to use the emergency eye wash station.

  6. This Looks Much Safer…

  7. Fire Safety: • Never get closer to an open flame than is necessary. Never reach across an open flame. • Confine loose clothing and tie back loose hair.

  8. Fire Safety: • Know the location of fire extinguisher and fire blanket. • If a student catches fire- use a fire blanket • If an object catches fire- use the fire extinguisher

  9. Fire Safety: • Turn off gas valves when not in use. • Use proper procedures when lighting a bunsenburner.

  10. Heating Safety: • Handle hot objects with tongs or insulated gloves. • Put hot objects on bench protectors, never directly on the table top.

  11. Sharp Objects: • Handle sharp objects carefully. • Cut in the direction away from your body.

  12. Electrical Safety: • Never use an electrical appliance near water or on a wet surface.

  13. Electrical Safety: • Do not use wires if the wire covering seems worn. • Do not pull on the cord to unplug an appliance – pull directly on the plug itself.

  14. Glassware Safety: • Never use broken or chipped glassware. • Never pick up broken glass with your bare hands. • Dispose of broken glass in the “broken glass” container.

  15. Poison: • Never touch, taste or smell any unknown substance. Wait for your teacher’s instruction.

  16. Caustic Substances: • Some chemicals can irritate and burn the skin. • If a chemical spills on your skin, flush it with plenty of water. Notify your teacher without delay.

  17. Toxic Vapours: • Some vapours can injure the skin, eyes and lungs. • Never inhale vapours directly. • Use your hand to “waft” a small amount of vapour towards your nose.

  18. Clean Up: • Wash your hands thoroughly after any laboratory activity. • Dispose of chemicals as directed by your teacher. • Put away all equipment as instructed.

  20. Labels on Hazardous Products HHPS and WHMIS Symbols

  21. Are Any of These in Your Home?

  22. Household Hazardous Product Symbols (HHPS) • Many products used in our homes may be dangerous if used incorrectly. • For this reason, household products are marked with symbols that allow us to recognize and interpret potential hazards

  23. Each symbol has two components: • Its shape tells you how hazardous a product is:

  24. Within each shape are symbols that tell you what kind of hazard the product is:

  25. Identify the meaning of the following symbols: Danger Corrosive Warning Toxic Caution Flammable Caution Explosive

  26. WHMIS SYMBOLS • The Workplace Hazardous Materials Information System (WHMIS) has produced symbols for hazardous products found in the workplace. • WHMIS symbols are similar to HHPS symbols, but are always in a circle • WHMIS symbols identify a wider range of hazards than HHPS symbols

  27. WHMIS LABELS • WHMIS labels are affixed or attached to the containers of controlled products, and provide information that: • Alerts the user to the hazards of the product • States what precautions to take when handling the product. • Refers the user to a material safety data sheet (MSDS) for more detailed information about the product.
