12 5. If chemical splashes into your eyes, what should you do? 6. Describe three steps to take that will sharply reduce the number of laboratory accidents. 7. List safety violations made by Sarah in the following situation. Sarah walked into the laboratory and began reading the day's experiment for the first time. She found her safety goggles too hot and cumbersome, so she removed them when she was not handling reagents. Sarah noticed a red solid in a reagent bottle on the side shelf. "I wonder what would happen if I heated some of this solid in a test tube," she thought. She put on her goggles and poured some of the red solid into a test tube, ignited the gas from her burner, threw the burning match into the sink, and began to heat the solid. As the solid was heating, a brownish-red vapor formed, which produced an unpleasant sensation when Sarah smelled it, startling her. At that point, her loose- sleeved blouse brushed the burner flame and caught fire. Sarah screamed, threw the test tube with the red solid on the floor, and ran from the laboratory
