HFI Safer Disinfection Brief - How 7 Minutes Once a Day, Protects Health, Saves Lives

 

The Healthy Facilities Institute (HFI) recommends using dry steam vapor (DSV) units as one of several safer disinfection methods.

 

While common "dwell" or wet-soak time needed for disinfecting is 5-10 minutes1, solid research shows dry steam vapor units with a proprietary TANCS® water-treatment module require just 2-7 seconds (not minutes) to kill most pathogens without chemical disinfectants, enabling safer disinfection. (Note: The manufacturer of TANCS-equipped units is perhaps unique in having peer-reviewed research backing several claims below.)

“During a time of year when many facilities are buttoned-up to save energy, limiting ventilation, and creating health hazards from touching or inhaling chemicals, DSV provides an effective chemical-free intervention for safer disinfection,” said Allen Rathey, principal of HFI.

 

Steps:

  1. The user adds tap water to a boiler.
  2. It warms up for 7 minutes.
  3. Dry steam vapor is applied using an insulated tool.

Applying DSV enables killing pathogens in seconds without chemical intervention as noted below.

“It takes just 7 minutes to add tap water and ready the dry steam which effectively disinfects in seconds,” said Rathey.  “This method can help to protect health and save lives.”

 

Future briefs will detail the utility of hypochlorous (HOCL) solution produced by ElectroChemical Activation (ECA) of Water, as well as tools for rapid and complete soil removal to render surfaces hygienic.
