CHAIR is actively working on healthcare plumbing system development to reduce infectious disease transmission.
A critical aspect of reducing healthcare acquired infections is to find the ideal layout of toileting facilities, and the accompanying plumbing and ventilation systems that will minimize infectious disease transmission at its source (e.g. fecal matter).
As infection control specialists know, toilet flushing produces an aerosol plume, and studies “…demonstrate that potentially infectious aerosols may be produced in substantial quantities during flushing. Aerosolization can continue through multiple flushes to expose subsequent toilet users. Some of the aerosols desiccate to become droplet nuclei and remain adrift in the air currents.”
* Research suggests that toilet plume could play a contributory role in the transmission of infectious diseases.
