Study Notes
Laboratory Safety Guidelines
- Closed-toed shoes are best for laboratory safety to protect against spills and heavy objects.
- Approved eye protection, such as goggles, should be worn whenever chemicals, heat, or glassware are present.
- Flammable materials, like alcohol, must never be used near an open flame to avoid fire hazards.
- In case of injury, wash hands thoroughly; skin treatments are not recommended right after an accident.
- Always wash hands after handling chemicals or biological specimens to ensure any traces are removed.
- Personal eyeglasses do not offer adequate protection in a laboratory setting; use proper safety goggles instead.
- Dispose of chemical waste as per instructor's directions to ensure safety and environmental compliance.
- Before starting an experiment, read directions carefully, check glassware for cracks, and clean dirty equipment.
- Rinse skin with plenty of water immediately if an acid is splashed for emergency acid management.
- If an experiment is unfinished, consult with the instructor instead of attempting to complete it independently.
- Report any malfunctioning equipment to the science instructor immediately and do not continue using it.
- Notify the instructor without delay in the event of a laboratory fire to ensure a proper response.
- Loose clothing, dangling jewelry, and sandals are prohibited in the lab to minimize hazards.
- Always point the open end of a heated test tube away from yourself and others to prevent accidents.
