what is the definition of biological control
an unprocessed biological form that is the same as the test monitor, it serves as a control by verifying the viability of the unexposed organism to the one that was exposed. ( The Controlled Subject)
what is a biological monitor
a bacterial endospore test that determines if sterilization actually occurred.
What is the definition of Blood Born Pathogen
Pathogenic microorganisms that are present in the blood
what is the bowie dick test

what is the definition of a noncritical items
instruments, equipment, or materials that do not normally penetrate or contact mucous membranes but which are exposed to splatter, sprays or splashing of blood, or are touched by contaminated hands.
what is the definition of engineering controls
equipment or methods that isolate or remove blood-borne pathogens from the workplace.
what is the definition of an exposure incident
a percutaneous exposure to blood or other potentially infectious materials, to the eye mouth or other mucous membranes, or non-intact skin.
what is the definition of exposure time?
the total continuous elapsed time during which the sterilizer is operating at the preselected sterilizing parameters, such as the temperature and pressure.
what is the definition of infectious micro-organism
organisms capable of producing diseases in a host
what is the definition of infectious waste
a liquid or semi liquid blood or other potentially infectious materials, or contaminated items that would release blood or caked with blood and are capable of releasing those materials if handling.
what is the definition of an invasive procedure
a surgical entry into the tissues, cavities, organs, or repair of major traumatic injuries. this includes the manipulation, cutting or removal or any oral or perioral tissue.
what is the definition of a nosocomial infection
an infection originating in the environment or a hospital or freestanding dental treatment facility.
what is the definition of personal protective attire.
specialized barrier attire worn by an employee to protect against a hazard.
what is the definition of occupational exposure
reasonably anticipated skin, eye, mucous membrane or parental exposure to blood or other potentially infectious materials that may result from the performance of your duties.
what is the definition of saturated steam sterilization
a process that uses steam under pressure for sufficient length of time to kill all forms of microorganisms.
what is the definition of sanitary sewer system
a sewer system connected to a sewage treatment plant
what does the term spray-wipe-spray mean
