You also need to know where the exits to the room are found and follow evacuation procedures quickly and quietly if needed.
Listen to all instructions before beginning any experiments.
Be aware of your surroundings and walk at all times when in the lab.

Never throw anything in the lab. Never taste or smell any of the chemicals in the lab.
Tell your teacher if you notice that some of your equipment is damaged before the lab begins.
You should always know exactly what chemical you are working with and the hazards associated with it.
A teacher should always be around to supervise when you dilute acids or bases.
