Safety is the top priority for everyone in the science classroom. The teacher is responsible for providing safe lessons, equipment, and instructions, while students must follow all verbal and written safety procedures without exception. Some general hazards include chemicals, sharp objects, fire, electricity, poisons, and corrosives. Students must wear safety goggles whenever required and sign a safety contract with their parent or guardian to participate in labs, agreeing to follow all safety protocols and instructions. Breaking the safety contract could result in removal from labs or other disciplinary actions.
