  1. Switching to a Safer Cleaner:How you can do it, How we can help Dr. Jason Marshall TURI Laboratory Director Jason_Marshall@uml.edu http://turicleanbreak.blogspot.com www.cleanersolutions.org www.turi.org/laboratory (978)934-3133

  2. What Have We Done • Providing technical assistance since 1993 • TURI Lab has helped hundreds of companies find safer alternatives to hazardous cleaning solvents • Process specific testing • The implementation rate for clients of the lab is three times higher than the national average for technical assistant providers • Prior to 2007, 33% of the companies fully adopt the lab’s recommendations • During past 2 years, near 80%

  3. Questions to Ask • What is the purpose of cleaning? • What are the problems with present cleaning system? • What are you trying to remove (soils)? • What is being cleaned (substrates)? • How are you cleaning it (equipment)? • How do you determine how clean is clean?

  4. Keys to Success • I. Product Selection Process • Helps to ‘scope’ project more efficiently • Determine substrate surface/ chemical cleaner reactivity issues • Review lab Safety Screening Scores • Using TURI’s CleanerSolutions Database for cleaning alternatives (www.cleanersolutions.org) • database selection process based on past performance and safety considerations • II. Temperature and Concentration Trials • Chemical field may be narrowed/changed from Phase I • Follow chemical manufacturer’s recommendations for both parameters • Equalize time • Minimize same-source agitation* • *chemical comparison tool; minimal use of mechanical energy; first round of scientific trials; gravimetric analysis • IV. Actual Product Cleaning Trials • Geometries and sizes of parts important to cleaning efficiency • Duplicate optimal PhaseIIIcleaning conditions • Duplicate optimal PhaseIIIcleanliness testing • III. Mechanical Energy Trials • Number of chemical cleaner candidates further decreases from Phase II • Application-specific • Economically-sensitive • Space-limiting • Conduct comprehensive EHS profiles of top performing products • scientific study; may employ a variety of analytical tools for cleanliness evaluation • V. Pilot Plant / Scale-up Feasibility Trials • Obtain input from employees that will be working on new process • Identify areas concerns • Arrange for lab loaning of equipment for further on-site testing • Follow up lab work based on client feedback

  5. CleanerSolutions • TURI Lab Database of Testing • Used to identify safer and effective products • Safety Screening Scores • VOC, ODP, GWP, HMIS/NFPA, pH • Matching Performance • Contaminant, substrate, equipment, current solvent www.cleanersolutions.org

  6. CleanerSolutions • How it works - www.cleanersolutions.org

  7. CleanerSolutions • Check it out on-line to start your search for a new cleaning method • www.cleanersolutions.org • Remember, It All Depends • Test on your specific soils • Using your parts • Following your cleaning process • TURI’s Lab can help you

  8. Questions? • Contact: • Dr. Jason Marshall • TURI Laboratory Director • Jason_Marshall@uml.edu • (978)934-3133
