General Guidelines 1. The teacher/laboratory technician has the sole authority inside the laboratory. Before using laboratory equipment, ask permission and assistance. Listen carefully to the instructions before performing an experiment. 2. The laboratory is a place where you will gain knowledge. It is not a place for horseplay and other unnecessary activities. 3. Do not eat or drink inside the laboratory. 4. To maintain orderliness, place bags and other materials not to be used in the experiment in a separate location. 5. Wear safety gears such as laboratory gowns and aprons, goggles, masks, and gloves while working in the laboratory.
