Lab Cleanup Points

In the organic chemistry teaching labs you are expected to take care of the equipment and lab space that you use. Each lab period, each individual has five possible points for lab clean-up. Those points are awarded to the whole class as a group. If the lab is left in disarray after your lab, you and everyone else in your section just lost points for lab clean-up. The following is a list of things that are expected of you:

  1. Lab stools put back on the counter top, right side up.
  2. Balances and weighing benches are clean, and used weigh paper is put in solid waste bins.
  3. Rotovaps and rotovap pumps are clean and turned off, bump traps are empty, and solvent traps have been emptied into organic waste.
  4. Fume hoods are properly tidied up:
    1. Sashes lowered (this should be done whenever you are not actively using hood).
    2. Lights turned off.
    3. All solvent/reagent/waste bottles capped and stored properly in tubs.
    4. All reaction equipment (ring stands, labjacks, hotplates, and heating blocks) stored in cabinets below hoods.
    5. UV lamp and DigiMelt stored in/on plastic shelves in hood, with cords wrapped up by velcro tie.
    6. Hood work surface wiped clean.
  5. All waste handled properly:
    1. Liquid organic waste - organic waste bottle in each hood. If bottle is full, it must be swapped for a new one.
    2. Liquid aqueous waste - aqueous waste bottle in each hood. If bottle is full, it must be swapped for a new one.
    3. Used rinse acetone - acetone recycling bottle in each hood. Note: ABSOLUTELY NO OTHER ORGANIC SOLVENTS may go in this container. Only acetone, water, and small amounts of solids. If bottle is full, it must be swapped for a new one.
    4. Solid chemical waste, filter/weigh papers, microcaps, and heavily contaminated paper towels/gloves - solid waste bins in each hood (NOT IN THE TRASH). If solid waste bin is full, its bag must be taken to the central collection point and replaced with a new one. Overflowing solid waste bins will get points docked for your lab.
    5. Broken glass - Tall blue and white "Broken Glass" disposal box near TA desk (ABSOLUTELY NOT IN THE TRASH).
    6. All other paper towels, gloves, and empty boxes - trashcan.
    7. Any experiment-specific wastes - recovery jar, as directed by lab manual.

If you follow these simple guidelines the labs will be in clean and organized for the benefit of everyone. Each significant violation of these rules will result in one point being docked from the cleanup points for your lab section, or two to three points for a serious violation.

Check-Out Cleanup Points

In addition to the normal cleanup duties, there are additional points for cleanup during checkout which vary depending on what time your lab meets during the week. If your lab meets twice per week, you should do the tasks for both times. For most of the "wipe down" tasks you should only need a wet paper towel followed by a dry one to dislodge any dirt. The used paper towels can go into the regular trash, unless heavily contamined with chemicals. For cleanup items inside fume hoods: Rather than checking every hood, the Lab Director will choose three hoods at random from each room and check how well each item in them has been cleaned.
