  1. Laboratory Safety

  2. Field and lab investigations • Science is a process • We begin with a question, and seek an answer by investigating the natural world • We use a variety of methods to investigate • Conduct experiments • Work of other scientists • We use tools (lab equipment) to help us find the answers we seek

  3. Safety in the Lab

  4. Basic Safety Rules • Never eat or drink in the lab. • Remain alert at all times. • Keep your area free of clutter. • Follow both written and verbal directions. • Unauthorized experiments can be dangerous. • Report any accident, incident, or hazard to me immediately, even if you think it’s “no big deal.” • Students may not work alone. • Remain at your workstation. The world needs more Lerts!

  5. Always wear goggles and other safety items. • If you get any chemical in your eyes, immediately flush your eyes (including under your eyelids) with water at the eyewash station for at least 15 minutes. Notify your teacher. • Secure all loose items. • Hair should be pulled back. • Contacts are not allowed. • Know where to find the safety equipment

  6. Blood and Body Fluids Safety • Wear gloves when someone is bleeding or vomiting • Clean everything touched by blood or vomit with a disinfectant • Remove your latex gloves by pulling them off inside out • All materials used to clean up blood or other possible infectious materials should be disposed of in the proper biohazardous waste bag • Standard Biohazardous waste bags are red with the biohazardous waste symbol on them. If one is not available, use a regular plastic garbage bag and attach biohazardous waste sticker to the bag • Wash your hands thoroughly with a disinfectant when you are finished

  7. Especially for IPC • Never pipette by mouth. • Throw away broken or chipped glassware • Hot glass looks like cool glass. • Hot glass does not go in water. • Point test tubes away from people when heating them. • Always pour acid into water. • Touch electrical devices only with dry hands. • Smell a chemical by waving your hand over it and letting the smell drift to your nose. • Don’t pour chemicals down the sink. • Never return unused chemicals to the original container.

  8. Safety Warning Symbols

  9. Read the Lab directions before beginning the lab! Oops, I was supposed to read the lab directions first!!!! Cool!

  10. Safety Terms: Caustic or corrosive- Will corrode or eat away metal, skin, or other substances. Volatile- Evaporates quickly, may form dangerous vapors. Flammable (may ignite)- will catch on fire or explode easily. Ventilation- removing contaminated air and brining in fresh air.

  12. Safety Equipment

  13. All chemicals must be labeled, and the label must include the NFPA hazard diamond Flammability Hazard Health Hazard Stability Hazard NFPA Hazard Sign Risk Level 0 Minimal 1 Slight 2 Moderate 3 Severe 4 Extreme Special Information

  14. How dangerous is this one? Extremely flammable Moderately unstable Not a health risk Keep away from water 4 0 2 W

  15. Fire Extinguishers • Extinguishers must be located and marked so they are easily seen in a laboratory • The extinguisher must be inspected annually and be tagged with the inspection history • PASS
