Understand that safety is the top priority when working with chemicals in a laboratory setting.
Recognize that ignoring safety data sheets (SDS) is dangerous because SDS provide important information about the hazards and proper handling of chemicals.
Avoid mixing chemicals over an open flame unless specifically instructed, as this can cause fires or explosions.
Never taste chemicals to identify them, as this poses serious health risks.
Always wear appropriate personal protective equipment (PPE) such as goggles, gloves, and lab coats to protect yourself from chemical splashes, spills, and exposure.
