Washington, D.C. 20590 Research and Special Programs Administration JAN 10 2001 Mr. Joseph Tan Reference No. 00-0291 Warehouse Supervisor Sakura Finetek U.S.A. Inc. 1750 W. 214 Street Torrence, CA 90501 Dear Mr. Tan: This is in response to your October 12, 2000 letter inquiring whether your company's product, a refrigeration unit, identified as a Tissue-Tek Cryo 2000, would be considered a "Refrigerating machine, UN2857" and, as such, not be subject to the Hazardous Materials Regulations HMR; 49 CFR Parts 171-180). You state that the refrigeration unit consists of a cold chamber and a microtome, which provides the means for freezing and cutting tissues for pathological examination. The machine contains 8 - 15 ounces of refrigerant R404A (pentaflouroethane and tetraflouroethane), is pressurized at 70- 80 psi at 70 degrees Fahrenheit, and weighs 238 pounds. Based on the information contained in your letter, it is our opinion that the Tissue-Tek Cryo 2000 would be considered a refrigerating machine. Section 173.307(a)(4), as amended, provides that a refrigerating machine containing 25 pounds or less of a non-flammable, non-toxic, liquefied gas is not subject to the requirements of the HMR (Docket No. RSPA 99-6213 (HM-218), 65 FR 50450, August 18, 2000). I hope this satisfies your request. Please contact us if we can be of further assistance. Sincerely, Hothe 2. Mitchill Hattie L.
