1. The student is not wearing safety goggles and is handling chemicals without gloves. This is dangerous because chemicals can splash into the eyes or be absorbed through the skin.
2. The student is eating in the lab. Food and drink should never be consumed in a lab to avoid accidental ingestion of hazardous substances.
3. The student is not wearing a lab coat and has long hair down. A lab coat protects clothing and skin, and long hair should be tied back to prevent it from catching fire or dipping into chemicals.
4. The student is pouring a chemical directly from the bottle into a test tube without using a funnel or measuring device. This can lead to spills, inaccurate measurements, and potential exposure.
5. The student is heating a test tube with a Bunsen burner but is holding it with bare hands and pointing the opening toward themselves. Test tubes should be held with tongs or a test tube holder, and the opening should point away from the user to avoid injury from splashes or explosions.
6. The student is mixing chemicals without knowing their properties or having proper ventilation. Mixing unknown chemicals can cause dangerous reactions; always check Material Safety Data Sheets (MSDS) and work in a fume hood if needed.
7. The student is leaving equipment unattended while heating. Never leave heating equipment unattended as it can overheat, catch fire, or cause explosions.
8. The student is not cleaning up spilled chemicals immediately. Spills should be cleaned up promptly using appropriate materials to prevent slips, contamination, or reactions.
9. The student is not labeling containers properly. All containers must be clearly labeled to avoid confusion and ensure safe handling of chemicals.
10. The student is not disposing of waste correctly. Chemical waste must be disposed of according to local regulations and lab protocols to prevent environmental harm or accidents.
