Lab safety rules

RULe # 1:

The laboratory is used for serious work. Horseplay can lead to chemical spills, accidental fires, broken containers, and damaged equipment. Talking among lab groups should be kept at a low volume. Frequently, you will be given directions during the lab that must be heard by everyone. Failure to hear your teacher’s directions can lead to injury or inaccurate lab results

Rule 2:

Never perform activities that are not authorized by your teacher. Read all directions for an experiment several times and discuss these with your lab group. Ask questions if you do not understand any part of the experiment. Follow the directions exactly as they are written.

Rule 10:

Never smell, touch, or taste any substance unless specifically told to do so by your teacher. When told to smell a chemical, use the wafting method by holding it 6 inches away from your nose and gently waving your hand over the opening of the container toward your nose. This will protect you from large doses of fumes that can be poisonous
