CM/Spotlight: Infection control — Science-based steps of the cleaning process
February 11, 2009
The February issue of CM/Cleaning & Maintenance Management® magazine is now available online, featuring the CM/Spotlight: Infection control — Science-based steps of the cleaning process article by Michael A. Berry, Ph.D.
Berry states that all matter transfers in and out of compartments, such as carpet, hard floors, fabrics and, to some degree, HVAC, is carried between compartments by physical displacement, gravitational settling, air current impact or filtration, electro-attraction or direct contact like tracking.
He notes that irregular or porous surfaces tend to collect and hold fast to foreign matter.
Berry adds that field demonstration research indicates that cost effective cleaning technologies easily maintain the source strength of carpet and other surfaces at levels not adversely affecting indoor air quality (IAQ).
