| Upon completion of the chemical surveys at the science laboratory classroom, preparation areas, and chemical storeroom, MSES prepares a Removal Chemical Inventory list for disposal cost evaluation purposes. |
|
| Our field personnel enters the list of the identified chemical reagents with expired shelf life codes into our proprietary Chemical Classification System (CCS) to classify and segregate the identified chemicals in accordance with USEPA and USDOT regulations. |
|
| Chemicals identified as having an expired shelf life code and having reached a retrograde condition are listed for removal. The chemical removal list is generated from the chemical survey conducted in the science laboratory's storeroom and preparation areas. |
|
| We classify, segregate, containerize, label, and prepare waste profiles for the selected disposal facilities, and complete the Uniform Hazardous Waste Manifest and the Land Ban Certification Forms. The packed drums are transported to hazardous waste disposal facilities that have provided MSES with the most cost-effective and environmentally sound disposal technology. Our personnel remove those chemicals with an expired shelf life/retrograde and retain chemical reagents that do not require removal. |
|
| The chemicals retained are listed in the Reconciled Chemical Inventory. The chemicals are then organized into organic and inorganic families based on the Flinn's Compatible Chemical Family Codes recommendations for the proper storage of hazardous materials. |
