Explanation:

1. False. Open - toed shoes like slides, sandals, and crocs are not allowed in the lab as they don't protect feet from spills or breakage.
2. True. Long hair and loose sleeves can catch fire or get caught in equipment when working with flame.
3. True. Inspecting glassware for cracks or chips prevents accidents during experiments.
4. True. Backpacks should be stored in designated areas to avoid tripping hazards and keep the lab organized.
5. True. Cleaning up spills immediately with proper materials helps maintain a safe and clean lab environment.
6. False. First - aid equipment should be in a fixed, known location and not moved around. Band - aids are part of first - aid supplies.
7. True. Running, throwing things, or horseplay in the lab is dangerous and can cause accidents.
8. False. Unused chemicals should not be returned to their original containers to prevent contamination.
9. True. Boiling water can splash and cause injury, so safety goggles are required.
10. False. Tossing objects across the lab table is dangerous and can cause injury or damage.
11. False. You should not pick up and examine equipment and chemicals without instructor permission.
12. True. Laboratory glassware may be contaminated and is not for drinking.
13. False. If unsure how to proceed during an experiment, you should ask the instructor, not try anything on your own.
14. False. Safety goggles or glasses should be worn at all times in the lab, not just when working with chemicals or an open flame.
15. Working alone in the lab is unsafe because there is no one to call for help in case of an accident, and there is no one to assist with procedures or emergencies.
16. Eating, drinking, applying makeup, or chapstick during a lab experiment is not allowed because these actions can introduce contaminants into the experiment and there is a risk of ingesting or spreading harmful substances.
