Biology Laboratory Safety Rules
- Never work alone in the laboratory without permission and prior knowledge of the instructor.
- Do not engage in rowdy, playful, or unprofessional activities in the laboratory. This includes not being disrespectful of your instructor or classmates.
- Students should wash hands thoroughly after first entering the lab.
- Students are allowed to have a drink with a lid during lectures and computer labs. Otherwise, they should never ever eat or drink anything in the laboratory without explicit permission from the instructor.
- Wear appropriate clothing at all times in the laboratory. Wear closed-toe shoes that cover the top of the foot, unless permission otherwise is given by the instructor.
- Wear examination gloves and safety glasses when dissecting or handling cadavers, caustic chemicals, bacterial broth cultures, or as otherwise advised by your instructor.
- Wear gloves when handling any microorganisms. Wear lab aprons or lab coats as advised by your instructor.
- Keep hands away from your face, eyes, and mouth when working with cadavers, chemicals, preserved specimens, microorganisms, or body fluids. This includes not applying cosmetics, not adjusting contact lenses, and not biting your finger nails.
- If any chemicals or other agents splash into your eyes, immediately go to the nearest sink and flush your eyes with water.
- Report ANY and ALL accidents, spills, BREAKAGES, or injuries to the instructor, no matter how trivial they appear.
- Scalpels and other sharp objects can be used only if authorized by the instructor and only after given proper handling instructions. Use small trays to carry all sharp objects. When handling sharp objects, point their tips down and away from other people.
- While wearing examination gloves, students must not leave the laboratory and must not touch any equipment such as microscopes, any personal items such as cell phones, or any door knobs.
- Do not use any lab equipment without instruction and authorization from the instructor. Report any damaged or broken equipment to your instructor immediately.
- Lab benches should be kept free of extraneous items while conducting experiments. This includes unnecessary books, backpacks, cell phones, and other personal items.
- Any pregnant or immunocompromised student must notify the instructor of the course. Pregnant students will not be allowed to do dissections or work with any body fluids without having a doctor’s note for permission. A pregnant student is required to wear safety glasses and 2 sets of examination gloves when handling any bacterial broths or cultures.
Universal Precautions for Students Working With Urine or Saliva
- Before lab, wash hands thoroughly and line the work area with clean paper towels.
- Students must wear gloves and may only handle their own body fluids.
- Students must wear lab aprons, safety glasses, and surgical masks.
- Rinse and dispose of all supplies that may have come into contact with urine or saliva in the appropriate biohazard container.
- Dispose of urine in the bathroom toilet and saliva in the sink.
- After lab, wipe down work area with disinfectant and wash hands thoroughly.
Disposal Policies
- Dispose of broken glassware in the marked cardboard box container. Broken glass containers are ONLY to be used for broken glass. Always use a broom and dust-pan if asked to clean up broken glassware.
- Dispose of used slides in the glass, or plastic, container labeled “Used Slides”.
- Biohazardous wastes must be disposed in a biohazard waste container. Preserved materials (e.g. cat tissues) are not considered biohazardous waste and can be disposed in the regular trash. Your instructor will inform you which disposal containers are to be used with which type of biohazardous waste (metal sharps, glass, and non-sharps).
- Uncontaminated gloves can be disposed of in the regular trash. Contaminated gloves must be disposed of in a biohazard waste container. Examination gloves used in dissections are not considered to be biohazard waste and can be disposed of in the regular trash.
Expectations
- Each student will leave the laboratory clean and organized for the next lab section. Leave your work area as clean, or cleaner, than you found it and return lab items to the designated locations in the drawers or cabinets. Make sure waste and trash are placed in the appropriate receptacles. Be sure to collect all personal belongings before leaving for the day.
- Each student is required to affirm at the end of the on-line safety quiz the following statement: “I have reviewed and I understand the laboratory safety rules for this course. I understand that I can be dismissed from that day’s lab activity for not wearing proper shoes and clothing, or for not following proper safety procedures. I understand that repeated safety violations may result in dismissal from the rest of the laboratory exercises without the option to make up any missed laboratory grades”. Out of safety concerns, a student will not be allowed to participate in any laboratories if s/he cannot agree to this statement.
