Public areas

The normal procedure for custodial care of the Chemistry Building involves scheduled cleaning of offices, classrooms, restrooms, laboratories and other public areas. Public areas are cleaned daily. Restrooms, classrooms, hallways, entrances, lobbies, elevators and most stairways are considered public areas.

Private offices

Private offices can be cleaned upon request. Please submit your request to Evelyn Knight

If your trash needs emptied, tie the liner up and place in the hallway after 5 p.m. Request additional liners from Evelyn Knight.

It is your responsibility to get recycling items to the blue containers in hallways. Chemistry Stores loans out equipment for moving instruments.

Sharps and glass

Sharps must be placed in sharps containers (obtained from Chemistry Stores), sealed, taped, labeled and left in hallway. Proper handling of brown glass bottles: remove caps, rinse bottles, and place in hallway.


Major project work is often scheduled between semesters and might include the following types of work:

  • Major light bulb changes
  • Buffing floors
  • Stripping/waxing floors
  • Cleaning carpets

Custodians will schedule project work in advance and post notices throughout the affected areas of the building. If light bulbs burn out in a work area, please report this to the front office and the bulb should be replaced during the regular workday. Problems with lights in fume hoods should also be reported to the front office. Custodians will change burned out bulbs in other areas of the building as they are discovered.
