  1. Competency 1.a. Lab Safety Rules andLab Symbols

  2. Why have safety rules in the lab? • To avoid accidents and injury. • The rules alert you potential hazards like dangerous chemicals or open flames. • To maintain experimental accuracy and reliability. • Keeping lab stations clean helps ensure that the experiment stays accurate and doesn’t get contaminated.

  3. Safety Rules: • Read ALL lab instructions thoroughly before beginning the lab. • Know the location of safety equipment (eye wash station, safety shower, etc.). • Tie back long hair. • No loose-fitting clothing and hanging jewelry. Wear closed-toed shoes and long pants. • Report any accidents to the teacher immediately!

  4. Safety Rules: • No food, drink, or gum in lab. • No applying makeup in lab. • Keep work station neat and clean. • Wear goggles as directed. • Contact lenses are prohibited. Bring your glasses instead. • Take care using sharp instruments. • Never cut objects while holding them in your hands.

  5. Safety Rules: • Never taste or smell any chemical. • Never mix chemicals without express instruction. • Keep your hands away from face/mouth during lab. • Always wash your hands prior to leaving the lab. • NO horseplay in the lab.

  6. Lab Contract: • A contract is an agreement. • By signing this contract, you agree obey all lab rules and procedures. • If you break any of the lab rules, you will be dismissed from the lab, given a zero for the assignment, and face potential disciplinary action depending on the offense. • Keep your signed lab contract in the first section of your notebook behind your syllabus.
