The Laboratory

            A lab is a special room equipped with instruments and chemicals for carrying out experiments.

Laboratory rules

Why must we follow rules in the laboratory?

            The laboratory can be a very dangerous place if rules are not followed because:

1. Many substance (chemicals) in the lab can harm us if we swallow them or handle them carelessly
2. Some of these chemicals can eat up our dresses or body parts if they come in contact
3. Some of these chemicals can easily explode.

 Due to the above reasons, scientists decided to bring up rules that we must follow when we enter the lab. The rules we must obey when we enter the lab are as follows;

1. Do not eat, drink or taste anything in the lab
2. Do not run carelessly in the lab
3. Do not touch any equipments unless your teacher tells you to do so
4. Do not touch your eyes, face, or mouth when using chemicals
5. We must wear protective glasses in the lab
6. Always put on lab jacket while entering the lab
7. Report all accidents to the supervisor
8. Do not forget to tie you hair if it is long
9. Tidy your station or bench while leaving the lab
