  4. General rules • Appropriate behavior - ALWAYS • Read the experiment first, don’t just copy other groups • Follow directions, don’t make up your own lab • Clean up as you go • Wash your hands • No food

  5. First aid Tell the teacher, even for little things

  6. First aid (continued) • Chemical spills • Small amount, non-toxic chemicals – rinse in sink with clear, cold water, at least two minutes • BIG spills, toxic chemicals – safety shower • Splash in the eyes – eye wash • Burns • Put under cold water • Teacher will get ice • Cuts • Rinse with plain water • Apply pressure Always let the teacher know

  7. Hot stuff • A hot beaker looks like a cold beaker • At least one supervisor for flame or hot plate • Keep your face to the side of the container that is heating • Use clamps or hot pads

  8. Hot stuff (continued) • If YOU catch on fire: • Stop • Drop • Roll • If someone else catches on fire: use the fire blanket • Fire extinguisher – tell a teacher, we’ll use it

  9. Chemicals • Follow directions • Touch, smell, or taste only when instructed • Waft, don’t snort • Take only what you need • Dispose of the extra, not back in bottle • No “mad scientist” • Measure carefully • Follow directions on clean-up

  12. A little pop quiz • When should you wear goggles? • When the experiment procedure directs and then as long as you have the chemicals or flame at the table • You catch your sleeve on fire and it quickly spreads to the rest of your clothes.
