Lab Safety Rules

 

 

1. You are not to perform unauthorized experiments in lab.

 

2. The chemical reagents used are in bottles with labels showing the chemical and the concentration.  Read the label carefully before removing the material because serious accidents can occur if the wrong chemical is used.  Do not take the reagent bottle to your lab table.  Never return unused material to the reagent bottle.

 

3. When heating or carrying out a reaction in a test tube, never point the tube at your neighbor or yourself.

 

4. Never taste a chemical unless directed to do so, as many reagents are poisonous when taken internally.  DUE TO THE TOXIC NATURE OF THE CHEMICALS USED IN LAB, THERE WILL BE ABSOLUTELY NO EATING OR DRINKING IN THE LAB OR CLASSROOM AREA.  When directed to smell vapors, do so by gently fanning the vapors toward your face.

 

5. If you receive a chemical burn, immediately flush the burned area with a large amount of water.  Tell the teacher at once.  REPORT ALL ACCIDENTS, NO MATTER HOW SLIGHT, TO YOUR INSTRUCTOR IMMEDIATELY.

 

6. Safety goggles must be worn at all times during the lab period.  Glasses are not an acceptable substitute.

 

7. Anyone engaging in deliberate unsafe acts will be taken out of the lab and will receive a zero.

 

8. All students in chem labs must wear a lab apron.
