Lab clean out

A lab clean out is the removal of a large quantity of chemicals or biological materials from the work area. Whether the clean out is to remove materials from previous projects or because the work area is closing or relocating, it is the initial responsibility of the supervisor/PI and work area personnel. The department then becomes responsible if the supervisor and personnel are no longer available. 

How to Get Started

Complete the Work Area Clean Out Request Form to notify the EHS Environmental Protection team of the clean out. You will schedule an initial waste evaluation to meet with Environmental Protection and identify all requirements pertaining to the clean out including proper packing and labeling.

Contact ehs.environmental.safety@ttu.edu with questions.

  1. Complete the Work Area Clean Out Request Form. You will be contacted after submission to schedule the initial Waste Evaluation.
  2. Meet with Environmental Protection for a Waste Evaluation to identify all waste requirements pertaining to the clean out. 
  3. Work area personnel must remove all EHS barcodes from chemical containers, place them on a Barcode Return Form and mail to EHS at Mail Stop 1090.
  4. Label and/or identify all containers to be collected. 
    1. All "waste containers" must be labeled with an EHS waste label and have all chemicals listed on the label. The container must be in good condition and have a lid. 
    2. Product chemical containers (i.e., manufacturer container) must be grouped with the appropriate hazard class and be clearly visible for collection. 
    3. Research samples must be grouped together with their appropriate hazard class and placed in a secondary container. The secondary container must have a completed EHS waste label affixed. If the samples are unknown, these containers must be placed in separate containment and have an EHS waste label affixed stating "unknown".
  5. Work area personnel must submit a Waste Request with an approximate total container quantity.
  6. Environmental Protection personnel will pick up your waste based on the queue of requests. During your meeting, EHS staff will provide you an approximate date of pick up. Keep in mind there can be hundreds of containers to pick up and a clean out is a lengthy process.


Equipment to be removed from the work area for relocation to another area or for disposal require appropriate decontamination by the supervisor (or department) and clearance from EHS before removal by TTU Surplus.
