How to determine what chemicals to use - ANSWER -The chemicals must
effectively remove the soil or stain from the surface without damaging the finish.
The manufacturer's recommendations for cleaning should be reviewed.
What is cleaning and disinfection? - ANSWER -Cleaning is a physical removal of
foreign and organic material from a surface. Disinfection is the inactivation of
disease-producing microorganisms. Thorough cleaning is a precursor to an
effective disinfection.
What are the 4 basic elements of cleaning? - ANSWER -Chemicals: time,
temperature, concentration and mechanical action. Generally, the longer the
chemical is allowed to work, the better job it does.
What are the 3 levels of disinfection and describe each? - ANSWER -Per (CDC),
there are three levels of disinfection: high, intermediate, and low. High level
disinfection is required for reusable equipment or devices that contact mucous
membranes, such as surgical instruments, and is generally done with autoclaves or
other ES departments will not be involved in high level disinfection. ES
departments should only use disinfectant products that are EPA registered as
hospital grade.
Describe low level disinfection - ANSWER -Low level disinfection will kill most
bacteria (except tuberculosis and bacterial spores), some viruses and some fungi,
and is generally required in areas where there is patient contact and the potential
for surface contamination exists.
Describe medium level disinfection - ANSWER -Intermediate level disinfection
will kill vegetative bacteria, including tuberculosis (except for spore forming
bacteria), most viruses and fungi, and is generally required in areas where
contamination with blood or body fluids is likely.
What is a phenotype? - ANSWER -the level of acidity or alkalinity in a solution.
Acids are in the 0-<7 range while alkalis are >7-14. Both acids and alkalis can be
physically damaging to surfaces, so they should only be used on surfaces or
finishes designed for cleaning with harsh chemicals. Cleaning chemicals identified
