In the Laboratory
The two most important principles that must be fulfilled whenever you work in a chemical laboratory are:
1) BE ACCURATE and
2) STRICTLY OBEY SAFETY RULES.
For this reason always bear these principles in mind:
1. Keep your working place in a good order and don’t change it without the permission from the instructor.
2. Before starting the experiment, read the manual and listen to the instructor, be quite sure that all the theoretical and experimental aspects are clear to you.
3. Check that all the equipment and chemicals required are on your bench. If no, approach the instructor or the technician. Never take any item from other benches.
4. Make sure that all the equipment you are going to work with is clean and if necessary, clean it.
5. All the experimental observations and quantitative data should be recorded immediately.
6. Strictly follow the procedure.
7. After finishing the experiment, clean all the equipment you used and your working place.
