      and after all laboratory activities.  
    • Read an assigned investigation carefully before beginning it, noting
      all cautions listed. 
    • Work deliberately and with a definite purpose, but do not
      hurry. 
    • Keep the workspace at your station and your apparatus clean and in good
      order. 
    • Read the label carefully before taking anything from a bottle or
      container. Using the wrong material could result in serious injury. 
    • Know what you are doing. Be aware of what neighboring students are
      doing.

    • All chemicals should be regarded as hazardous unless your instructor
      informs you otherwise. 
    • Never mix or heat chemicals unless you are directed to do so. 
    • When mixing concentrated acids and water, always pour acids into water slowly and stir constantly.

    • Never taste a chemical or a solution or touch chemicals with your hands unless directed to do so by your instructor. 
    • When heating a test tube, do not heat just one spot on the test tube. Never have the open end of the test tube pointed at anyone. Never look directly down into a test tube. 
    • Always allow ample time for cooling after materials have been heated. 
    • Dispose of all materials as instructor designates.
