Researchers Warn About Germ ‘Splashback’ from Wash Basins

The New Study Led by Flinders University has Found That the Speed ​​at Wich Water Flows From a Tap Can Significant Impact The Possible Risk of Infections Spreading in Hospital and AGED-Care Settings.

The Article, “The Impact of Water Flow Rates on BioArterol Production from Handwashing Basins“Has been published in Building and Environment.

Production of Bioarosols –or Airborne Water Particles That May Contain Bacteria or Viruses – Post Significant Public Health Concern, Environmental Health Experts Warn.

“This Research HighLights an often-Overloked Factor in Infection Control, Raising the Potential for More Infection Control in Health Care Settings and Public Spaces,” Says Flinders Adjunct Academic Dr. Claire Hayward, Who is now a Postdoctoral Research Working on Antimicrobial Resistance in the Community.

“In Hospital and AGED-Care Facilities, BioArosols Generated from Handwashing Basins Have Been Linked to Health-Care-Associated Infection Outbreaks,” Says Dr. Hayward, Lead Author of a New Article in the Building and Environmentalment Journal.

“However, There has Been Limited Research on How Basin Design Parameters, Such as Flow Rate Restrictors, Impact Bioerosol Production and Transmission Routes.”

The Findings Show that All Three Flow Restricts Tested Produced Respirable-Sized Bioerosols. While there in the Significant Difference in the Number of Aerosols and Droplets Originating from the Source Water Across Different Flow Rates, Lower Flow Rates Led to an Increased Generation of Aerosols from the drain and greater retrograde contamination from the drain to the faucet.

This suggests that While Reducing Water Flow May Help With Water Conservation, It Could Inadvertently Increase the Spread of Potentially Harmful Microbes.

Senior Author of the Study, Flinders University Professor Harriet Whiley, Says, “These Results Highlight the Complex Relationship Beteen Plumbing Design and Infection Control.”

“By Optimizing Design Elements Like Aeraors and Flow Rates, We May Be Able to Reduce Infection Risks, But Further Research is Needed to Identified the Safest and Most Effective Setarations.”

“The Study Underscores The Importance of Collaboration Between Product Designers, Engineers, and Microbiologists to Develop Hand Basin Designs That Balance Functionality With Infection Prevention,” Says Professor Whiley, From the College of Science and Engineering at Flinders.

The BioArterol Transmission Continues to be a Concern in High-Risk Environments, These Insights Could Informa Future Plumbing Innovations and Health Care Policies, Researchers Conclude.
