Final answer:
Report broken or cracked glassware to the teacher and use the correct disposal methods; follow lab safety protocols; and handle chemical waste appropriately.
Step-by-step explanation:
Broken or cracked glassware should always be reported to the teacher and then placed in the proper waste container. When working in a chemistry lab, it's important to follow safety protocols to prevent injuries and ensure proper disposal of materials. For example, use gloves, goggles, or safety aprons when instructed to do so. Broken glass should only be cleaned up with a dust pan and broom, taking care not to touch broken glass with your bare hands. In the event of accidents or chemical spills, you must call your teacher immediately. Additionally, always check with your teacher on how to dispose of waste, as chemicals should not be indiscriminately disposed of down the sink. When disposing of chemical waste, it must be unused and in the form of a commercial chemical product.
