10. Exposure Control Written Exposure Plan  Preventive measures  Documents exposure  Indicates appropriate action  Steps to correct an exposure situation Occupational Exposure  Anticipated exposure on the job to: Blood Saliva OPIM  Other potentially infectious materials

11. Risk of exposure Exposure Determination Chances of having an exposure  Category I Always / usually involves exposure to blood / saliva  Dentists  Hygienists  Assistants  Category II Occasional / possible contact with blood / saliva  Receptionist  Lab case driver  Category III Rare / no contact w/ blood/saliva  Bookkeeper  Office manager

13. Sterilization Process of killing all forms of life.  Autoclave  Cold sterile Glutaraldehyde  Performed on: Instruments Handpieces  Between every patient Ultrasonic cleaner  Vibrates debris off of instruments. Cavitation process No handpieces 3 – 10 min. Biological monitor  “spore test”  Ensures sterilization has occurred. Autoclave is working.  1 X per week.

14. Process Indicator Different than the “spore” test.  What is in the bag has been ‘heated’.  Gone through the process  Color change dot/arrow on bag  Process Indicating Tape. Both change color when exposed to heat
