Final answer:
In addition to wearing appropriate personal protective equipment, a student should point the test tube away from anyone, handle hot glassware carefully, work in a well-ventilated area, secure loose items when using an open flame, follow specific lab instructions, and avoid eating or drinking in the lab.
Step-by-step explanation:
When heating a test tube with an indicator solution and glucose, it is essential to follow additional safety procedures beyond wearing safety goggles and a lab apron. One important safety procedure is to point the test tube away from oneself and others while heating to prevent burns or spills if the solution reacts or boils over. Also, it is crucial to handle all glassware with care, particularly when it is hot, to avoid burns or breaks. When using an open flame, such as that from a Bunsen burner, one must ensure that all loose clothing and hair are secured and that the flames are never left unattended. Another key safety measure is to work in a well-ventilated area to avoid inhaling any potentially hazardous fumes and to use the fanning motion to waft vapors if necessary, rather than directly smelling any substances.
In addition, adherence to any specific lab instructions or teacher directions regarding the safe use of chemicals and heating equipment is imperative. This includes never eating, drinking, or tasting any substances in the laboratory. After completing the experiment, it's important to turn off all heat sources and safely store all chemicals. Lastly, one should thoroughly clean all equipment used, as residual substances may interfere with future experiments or pose safety risks.
