Note Exercise caution during this entire lab!

• Wear gloves.
• 2. Handle only your own blood.
• 3. Dispose of used lancets immediately by placing
  them in the sharps container. DO NOT LAY USED
  LANCETS ON THE LAB BENCHES!
• 4. Contaminated reusable items (microscope
  slides, glass stir rods, etc) go into the 10
  bleach solution. Disposable items (cotton balls,
  toothpicks, etc) go into the red biohazard bag.
• 5. Clean up after yourselves using the bleach
  solution in the squeeze bottles.
• Your safety and the safety of your fellow
  students depends upon good lab practices. These
  are the types of precautions that you will be
  expected to practice in your future careers. Now
  is a good time to get started.
