Chapter 6: Equipment for Infection Control

Cleaning, Sanitizing, and Disinfecting Claims and EPA Registration Due to the contact or dwell time requirements that the surface must remain wet to achieve sanitization or disinfection (2–10 minutes), Tennant has not pursued registration of ec-H2O because it is in contact with the flooring surface for only 2 to 3 seconds Includes claims to effectively kill a broad range of microorganisms within 3 to 5 seconds, reducing surface- mediated infection risks. Classified as a disinfection device with a 3- to 5-second dwell time and is effective against a broad spectrum of microbes.

Independent Research and Third-Party Certification Aspen Research Corporation in St. Paul, Minnesota, performed third-party testing. The technology has also been tested by NSF International for use in food, beverage, and drug processing locations. ec-H2O is certified by Underwriter's Laboratories (UL). Nelson Laboratories, Inc. of Utah certified that a 7-second exposure to TANCS steam vapor produced a 5- to 7-log reduction in microbes, which was consistently achieved on all microbes tested. Test steps: 1. Microbes were grown in liquid culture or harvested from stock

Technology

Tennant Auto Scrubbers

Uses activated-water technology, called ec-H2O ™ , in a line of their auto scrubbers. This is the same technology that is used in the Activeion products.

Tennant Company developed Activeion’s activated-water technology (ec-H2O) and then licensed Activeion Cleaning Solutions to develop the hand sprayers. Benefits include reduced chemical and water usage, and the elimination of chemical residue on floors. Does not use chemicals, only tap water. It can penetrate deeply and quickly into nooks, crevices, and microscopic pores in surfaces. Although it has a dry (6%) moisture content, the manufacturer recommends that to reduce risk for mold after use, all surfaces must be dried and rooms must be ventilated and not closed

Thermal Accelerated Nano Crystal Sanitation (TANCS ® ) Steam Vapor System Developed by Advanced Vapor Technologies, LLC Bauer Energy Design, Inc. holds the patent on this technology.

The TANCS Steam Vapor System technology (see Figure 2) works by facilitating the redistribution of charges between the water molecules and dissolved mineral components naturally found in tap water, which results, in part, in the development of nano crystals. This enhanced water is then transformed into super-heated, low-moisture steam. Creation of the nano crystals results in a micromechanical component in addition to a
