Lab Safety and Equipment Guide: Ensuring a 100% Safe Science Environment

This comprehensive guide covers lab safety protocols and essential equipment in scientific settings. Learn about acceptable safety goals, lab equipment such as beakers, graduated cylinders, test tubes, agar plates, triple beam balances, rulers, and thermometers. Safety precautions for each item are provided to ensure injury prevention. Achieve a 100% safe environment with proper handling and usage of lab equipment. Watch a science safety video for a visual demonstration of safety practices.

  7. What is an acceptable safety goal for a science lab? • Is 90% acceptable? • Number of classes per day = 6 • Number of students per class = 28 • Number of years in a career = 30 • So the total number of students taught in a career would be 6x28x30 = 5040 • If just 1 student got seriously hurt, my safety percentage would be 5039/5040 = 99.98%

  8. 99.98% is pretty good unless you are the 1 student that gets seriously hurt! • So my goal is 100%

  9. Lab Equipment- Biology

  10. # 1: Beaker #2 : Graduated cylinder • Uses: • Measure, store and heat liquids • Large amounts • Uses: • Measure and store liquids • Small amounts • More accurate Safety Precautions: Glass is breakable Hot glass looks like cold glass

  11. #3: Test tube #4: Agar Plate • Uses: • For growing bacteria; the red jelly is the agar. It is full of “food” for bacteria • Uses: • To store small amounts of liquid (usually) Safety Precautions: Test tube is glass = breakable Agar is NOT food for people (no eating)

  12. #5: Triple beam #6: Ruler Balance • Uses: • Get the mass of objects and materials • Units are grams • Uses: • Get the length and/or width of geometric shapes • meters or cm Safety Precautions: TBB are heavy Rulers are NOT small swords or bats– don’t use them that way!

  13. #7: Thermometer • Uses: • Get the temperature of liquids being heated • Units are oC and/or oF Safety Precautions: usually glass so handle with care
