Perform laboratory work only when your teacher is present. Unauthorized or unsupervised laboratory experimenting is not allowed.
Your concern for safety should begin even before the first activity. Always read and think about each laboratory assignment before starting the laboratory activity.
Know the location and use of all safety equipment in your laboratory. These should include the safety shower, eye wash, first-aid kit, fire extinguisher, blanket, exits, and evacuation routes.
Wear a laboratory apron and safety (impact & splash-proof) goggles for all laboratory work. Shorts (i.e., PT uniform) must not be worn.
Clear your bench of all unnecessary material before starting your work. Textbooks are not allowed into the lab.
Check chemical labels twice to make sure you have the correct substance and the correct concentration of a solution. Some chemical formulas and names may differ by only a letter or a number.
You may be asked to transfer some laboratory chemicals from a common bottle or jar to your own test tube or beaker. Do not return any excess material to its original container unless authorized by your teacher.
Avoid unnecessary movement and talk in the laboratory.
Horseplay is not allowed and will be dealt with extreme severely.
Never taste laboratory materials. Do not bring gum, food, or drinks into the laboratory. Do not put fingers, pens or pencils in your mouth while in the laboratory.
If you are instructed to smell something, do so by fanning some of the vapor toward your nose. Do not place your nose near the opening of the container. Your teacher will show the correct technique.
Never look directly down into a test tube; view the contents from the side. Never point the open end of a test tube toward yourself or your neighbor. Never heat a test tube directly in a Bunsen burner flame.
Any laboratory accident, however small, should be reported immediately to your teacher.
In case of a chemical spill on your skin or clothing, rinse the affected area with plenty of water. If the eyes are affected, water-washing must begin immediately and continue for at least 10 to 15 minutes. Professional assistance must be obtained.
Minor skin burns should be placed under cold, running water.
When discarding or disposing of used materials, carefully follow the instructions provided.
Return equipment, chemicals, aprons, and protective goggles to their designated locations.
Before leaving the laboratory, make sure that gas lines and water faucets are shut off.
Wash your hands before leaving the laboratory.
If in doubt, ask!
