Pam,
I wonder if you have spoken with the custodial operations people at your institution about the expected frequency of trash removal? Typically, custodial services at academic
institutions try to follow and maintain a certain “APPA level” of cleanliness.
APPA levels refer to a five-level cleaning and maintenance scoring system developed by the organization
APPA: Leadership in Educational Facilities. These levels range from Level 1: Orderly Spotlessness to Level 5: Unkempt Neglect, with each level corresponding to a specific standard of cleanliness and a set of defined criteria
for tasks like floor care, surface cleaning, and waste removal.
Due to budget and staffing constraints (which translates to limitations on time spent that can be spent on tasks), custodial services can only provide a certain APPA level.
However, they should be able to work with you to identify certain tasks or services that need to be improved (more frequent trash removal in labs in your case), often in exchange for other tasks/services getting less attention.
I hope this helps.
Regards,

Subject: [DCHAS-L] General trash removal from labs
I hope that it is acceptable for me to post my question here. I would like to know if there are any regulations related to the removal of general trash from chemistry
laboratories in regard to frequency. We seem to be having challenges institutionally and I would like to approach this issue from a safety standpoint. Also, does it matter whether we are speaking of a teaching lab or a chemical research lab.
