Safety in Science

1. Safety in Science We don’t want any trouble !

2. What we worry about • What to wear • General rules • First aid • Hot stuff • Chemicals • Clean up

3. What to wear • Goggles, when listed • On the eyes • All the time • Tie long hair back • No baggy clothes

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

10. Clean up • Follow directions • Different chemicals different clean-up • Sometimes in the trash • Sometimes down the sink • Sometimes in a special container • Includes equipment, table, and floor • Clean up as you go, don’t wait until later

11. A little pop quiz • What should you do if you get a small amount of chemical splashed on your arm? • Rinse in cold water for at least 2 minutes and tell the teacher • If you are pretty sure what will happen, can you mix together two powders that you have left over from your experiment? • No, no, no! • True or false: you always clean up by putting things in the trash • Not always, only when the directions say to do that

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. Should you: • Run and get the fire blanket • Ask your lab partner to squirt you with the fire extinguisher • Stop, drop, and roll • Stop, drop, and roll • What is the safety shower used for? • Large spills of toxic chemicals on a person

13. Follow Directions The most important thing:
