Cleaning and disinfection

Monitor cleaning instructions
It is important that monitors used for viewing mammographic images be kept clean and free of fingerprints,
dust, etc.
These instructions are applicable to LCD and CRT monitors.
Use a microfiber cloth to clean the monitor screen and housing. If necessary, moisten the cloth with either
clean water or ethyl alcohol (up to 96%). Do not allow any drops of cleaning liquid to remain on the surface;
extended contact may cause discoloration of the surface.
! Notice:
Do not use isopropyl ("rubbing") alcohol.
Do not use cleaning agents which attack the surface, such as petroleum (mineral) spirits.
The front panel is extremely sensitive to mechanical damage. Avoid all scratches, knocks, etc.
Do not apply the cleaning liquid directly to the monitor housing or screen.
Do not allow the cleaning liquid to enter the monitor housing; be sure to dampen the cloth sparingly.

General information about disinfection
CAUTION
Adequate cleaning and disinfection is necessary to prevent disease transmission. Be sure to
thoroughly clean and disinfect equipment surfaces that contact the patient and all equipment
surfaces likely to become soiled during use.
The level of disinfection required for a patient contact device depends on the type of contact that occurs:
•
A CRITICAL device is one which routinely penetrates the skin or mucous membranes during use and
therefore poses a high risk of infection if it is not sterile. Such devices (e.g., surgical instruments, nee-
dles, catheters or infusion sets) must be made
sterile
prior to use.
•
A SEMI-CRITICAL device is one which contacts mucous membranes but does not penetrate normally
sterile areas of the body. Such devices (e.g., endoscopes, speculum) should be made sterile whenever
practical, but
high level disinfection
is usually acceptable prior to use.
•
A NON-CRITICAL device is one which contacts intact skin during routine use. Such devices (e.g., patient
exam tables, blood pressure cuff, etc.) present a much lower risk of infection and, therefore, a
low level
disinfection
is usually acceptable. However, in cases when there is concern for cross contamination, an
intermediate level disinfection
should be done between patients.
