Lab Safety and Measurement

Staying Safe in the Chemistry Lab

Safety is a top priority! Always wear goggles, gloves, and a lab coat. Know where safety equipment like eyewash stations and fire extinguishers are.

Measurement Basics

  • Use the correct glassware for measuring liquids (graduated cylinders for accuracy).
  • Always read the meniscus at eye level.
  • Record all measurements with correct significant figures.

Why It Matters

Accurate measurements and good safety habits lead to reliable, repeatable results—key for scientific discovery!

Real-Life Chemistry

  • Pharmacists measure chemicals for medicine precisely.
  • Water quality testing relies on accurate measurement.

Examples

  • Wearing goggles protects your eyes from chemical splashes.

  • Using a graduated cylinder ensures you measure the right volume.
