- Bacteria, blood, and animal tissue will have biohazard collection containers available in the hood, which must be requested by the faculty member when submitting supply requests. Leave the biohazard container in the hood at the end of lab.
- Leave lids loose on living cultures, unless transporting them to Pocatello (tighten lids for the journey and then loosen them again when you arrive). Only transport organisms if you have specifically been requested to do so. If organisms are to remain in Idaho Falls, leave a note stating whether they should be kept or disposed of.
- Treat all living and dead animals with respect. Callously hacking into organisms, arranging them into “humorous” poses, or making jokes about living or dead organisms is unacceptable behavior.
- A container for a collection of preserved animal tissue should be requested by the faculty member in charge of the lab. This container will be located in the hood.
- After all of the week’s labs are complete (or when full, or when it starts to smell), tie the bag tightly shut, label it, and put it in the freezer.
- Leave a note for the lab materials supervisor when the freezer is full or no more animal waste will be generated during the semester, so that pickup may be arranged.
- A “dirty slide” container is provided in the back of the lab for disposal of student-created non-hazardous wet mount slides. Plastic coverslips can be disposed of in the trash.
- Request a biohazards container for slides that require it.
- Please ensure that commercially prepared slides do not go in these containers.
- Lab instructors do not need to empty or move dirty slide containers.
||Accidents: All accidents should be reported using the accident form and filed with the Laboratory Materials Supervisor on your campus and the lab coordinator.
Cleanup Expected of Students:
- Remove all markings from empty glassware (wipe off wax pencil marks with a dry paper towel; remove all tape). Clean/rinse glassware so it is ready for the next lab.
- Dispose of only appropriate items in the trash (no chemicals, biohazards, sharps, glass): gloves, paper towels, Kim wipes, lens paper, plastic coverslips, scraps of parafilm, and other paper/plastic trash are ok. Our labs do not contain anything so hazardous that small amounts of chemical contamination on gloves or paper towels are hazardous. If a paper towel is completely saturated with a chemical, you may leave it with the chemical waste in the hood.
- Return any prepared slides to the proper boxes.
- Return microscopes in the proper condition to correct cabinet (# on microscope must match # on cabinet).
- Cord is wrapped neatly and tucked in
- Lowest power lens is in place
- Empty stage (no slides)
- Aligned arm & eyepieces (head not rotated)
- Racked down & centered stage
- Then make sure students add the dust cover and return them to the proper cabinet number.
- Log off the computer and shut the lid. These computers are on the ISU system and if a student fails to log off, they will be blocked from logging on to any other computer on campus.
- Other materials
- If there are more lab sections during the week: students should leave all materials where they found them when they arrived in the lab. If it was on their bench, they should leave it there. If it was on the back bench, it should be returned there.
- For the last lab section of the week: Return all materials to the large island in the back of the lab. Only the following items should be left on the student benches next to the sink: DI bottle, alco Nox wash bottle, handsoap, and Kim wipes
- Wipe down lab table using alco Nox and paper towels.
- Push in lab stools.
Cleanup Expected of Lab Instructors:
- Ensure that students are putting their waste in the appropriately labeled containers in the hood. Absolutely no chemicals should be left in general lab glassware at the end of a lab. Only stock chemical bottles and labeled waste containers should contain chemicals after a lab.
- Ensure that students have removed all markings from glassware and cleaned/rinsed them so they are suitable for the next lab section.
- Check prepared slide boxes to make sure that all prepared slides are accounted for. If a prepared slide has been broken during a lab, leave a note (and then put it in the broken glass). Small chips can be sanded down to make them safe and the slides can still be used. Leave a note if a slide has a chip and needs to be sanded for safety.
- Check that the microscopes have been put away properly (in the proper condition and in the proper cabinet) and lock the cabinets.
- If there are more lab sections after yours, make sure that all glassware, chemicals, and equipment have been returned to the proper place in the proper condition (clean!) for the next lab. Notify the lab materials supervisor if chemicals or supplies are running low.
- If you have the last lab of the day (even if it is not the last lab of the week), return all perishable items to the refrigerator and turn off all electrical equipment (water baths, electrophoresis equipment, spectrophotometers).
- If you have the last lab of the week, put all glassware, chemicals, and equipment back on the supply cart. All items should be clean, but glassware does not need to be spotless, as it will go through the dishwasher prior to reuse. The cart can be left in place in the lab. It does not need to be moved elsewhere. Large items (spectrophotometers, balances, electrophoresis equipment, laptops) may be left on the large back island. The only things that should be left on student benches at the end of the week’s labs are these items that are always next to the sinks: DI water bottle, alco Nox wash bottle, handsoap, and Kim wipes.
- Turn off the projector, log off the instructor computer, and close the computer.
- Turn off the lights and lock the doors to CHE 107 and/or 108 when your labs are finished. Note that the push-button lock on the inside of the door only locks the door when it is already closed (this allows students to lock the door from the inside if there is an active shooter event). If you push the button lock while the door is open, it unlocks when the door closes. Thus, if you are on the outside of the door, you must use a key to lock the door (NOT the push button lock).
End of Semester:
- Clean out drawers in front bench.
- Ask lab materials supervisor if any other cleanup needs to be done.
