BLOODBORNE PATHOGENS

1. BLOODBORNE PATHOGENS THE OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION STANDARD

2. INTRODUCTION • What is the bloodborne pathogens standard? • Who needs bloodborne pathogens (BBP) training? • What content needs to be covered?

3. Duties of Employers provide a plan identify job types and classifications provide appropriate training provide appropriate equipment Compliance Duties of Employees to follow the employer’s plan to use equipment provided by the employer Compliance OSHA’S EXPECTATIONS

4. OSHA REQUIRED INFORMATION • Documents • General explanation of bloodborne pathogens • Hepatitis B immunization • Explanation of tasks that may involve exposure

5. BLOODBORNE PATHOGENS DEFINED • Disease-causing microorganisms that may be present in human blood or OPIM (other potentially infectious material) • Viruses • Bacteria • Parasites

6. MODES OF TRANSMISSION • Puncture wounds or cuts • Contact (Touch, Splash, or Spray) with blood or OPIM on: • mucous membrane • non-tact skin • cuts, abrasions burns • acne, rashes • papercuts, hangnails • contaminated sharps

7. RISK OF EXPOSURE • The objective of the BBP standard is to minimize or eliminate the hazard posed by work that may expose you to blood or OPIM

8. RISK OF EXPOSURE • If a risk of exposure exists, you must know: • if there is a way to prevent infection • the symptoms and course of infection • that counseling is available • that post-exposure treatment & follow-up are available

9. OCCUPATIONAL EXPOSURE INCIDENTS • Occupational contact with blood or OPIM is considered an exposure incident • If an exposure occurs: • wash with soap & water • report the incident • document the incident • seek “immediate” medical evaluation • follow employer’s exposure control plan

10. IMMEDIATE MEDICAL EVALUATION • Immediate means prompt medical evaluation and prophylaxis • An exact time cannot be stated • Time limits on the effectiveness of prophylactic measures vary depending on the infection of concern

11. Date and time of the incident Job classification Location in the worksite where the incident occurred Work practice being followed Engineering controls in use Procedure being performed PPE in use REPORTING AN INCIDENT Minimal information to report

12. Medical Evaluation After an Exposure Incident • Entitled to confidential medical evaluation • Personal decision about blood testing • Blood may be tested only with consent • Blood may be stored for 90 days, while considering testing • Interpretation of any test results occurs with the health care provider

13. BLOOD TESTING • Blood may be tested for antibodies to: • Human Immunodeficiency Virus (HIV) • Hepatitis C Virus (HCV) • Hepatitis B Virus (HBV) • Other disease-causing organisms • Source blood may also be tested with consent • The results of the tests of source blood will be made known to you

14. SPECIFIC BLOODBORNE PATHOGENS • Definition • Signs and Symptoms • Course of infection • Prevention and control • Post-exposure prophylaxis and follow-up care

15. HIV DEFINED • HIV is the Human Immunodeficiency Virus • HIV causes acquired immune deficiency syndrome (AIDS) • Risk of HIV infection from a puncture injury exposure to HIV infected blood is very low -- 0.3%

16. SIGNS & SYMPTOMS OF HIV • Signs and symptoms include: • Weight loss • Night Sweats or fever • Gland Swelling or pain • Muscle and/or joint pain • Cannot rely on signs and symptoms to know if you are infected

17. COURSE OF INFECTION OF HIV • Incubation period from HIV infection to AIDS may be 8 to 10 years • Varies greatly among individuals

18. HIV PREVENTION • There is no vaccine to prevent HIV infection • Follow Universal Precautions

19. There is no cure for HIV infection Testing for HIV antibodies at time of exposure at 3 months at 6 months HIV antibodies usually become detectable within 3 months of infection Treatment of HIV requires visits with your health care provider OSHA requires recommended treatment meet the most recent CDC guidelines Treatment can include antiviral medications and a protease inhibitor HIV Post-exposure Prophylaxis & Follow-up

20. HCV Defined • HCV is Hepatitis C Virus • It affects the liver • It is the most common chronic bloodborne infection in the United States • Needlestick injury is the only occupational risk factor that has been associated with HCV • Risk of HCV infection after exposure to HCV infected blood is 1.8% • 70 to 75% of those with acute HCV infection have no symptoms

21. SIGNS & SYMPTOMS OF HCV • Jaundice - a yellow color to the skin • Fatique • Headache • Abdominal Pain • Loss of appetite • Nausea & Vomiting

22. COURSE OF HCV INFECTION • Incubation period averages 7 weeks • Chronic liver disease may occur in 70% of those infected with HCV

23. HCV PREVENTION • There is no vaccine to prevent HCV infection • Follow Universal Precautions

24. There is no cure for HCV infection No recommendation for post-exposure prophylaxis Tests for HCV antibodies & liver function tests should be done at time of exposure Tests should be repeated 4 to 6 months after exposure Treatment of HCV requires visits with your health care provider OSHA requires recommended treatment meet the most recent CDC guidelines HCV infection may require liver transplantation for treatment HCV Post-exposure Prophylaxis & Follow-up

25. HBV DEFINED • HBV is the Hepatitis B Virus • It affects the liver • The prevalence of HBV infection among healthcare workers is 10 times greater than HCV infection

26. SIGNS & SYMPTOMS OF HBV • Jaundice - a yellow color to the skin • Fatique • Headache • Abdominal Pain • Loss of appetite • Nausea & Vomiting

27. COURSE OF HBV INFECTION • Incubation period averages 12 weeks • Most cases of HBV resolve without further complication • Chronic liver disease may occur in 6 to 7% of those infected with HBV

28. HBV PREVENTION • There is a vaccine to prevent HBV infection • It is required to be offered to anyone covered by the BBP standard • Follow Universal Precautions

29. There is no cure for HBV infection Post-exposure prophylaxis should begin within 24 hours and no later than 7 days after exposure If not previously vaccinated, the person should receive the HBV vaccine Treatment of HBV infection requires visits with your health care provider OSHA requires recommended treatment meet the CDC’s most recent guidelines Chronic HBV infection may require liver transplantation for treatment HBV Post-exposure Prophylaxis & Follow-up

30. HBV IMMUNIZATION • All people with routine occupational exposure to blood or OPIM have the right to receive the HBV vaccine at no personal expense • Refusal requires signing the Hepatitis B Vaccination declination form • Vaccine is Recombivax HB or Energix - B • Vaccine is prepared from recombinant yeast cultures • Must be made available within 10 working days of initial assignment to job

31. HBV VACCINATION SCHEDULE • Vaccine is given in 3 doses over 6 months • 1st on initial assignment • 2nd one month later • 3rd five months after 2nd dose • CDC recommends Hepatitis B antibody testing 1 to 2 months following the 3rd dose • Employer cannot require you use your health insurance to cover the cost • Pre-screening is not required • HBV is declining because of vaccine use!

32. PREVENTION • Engineering Controls • Work Practice Controls • Personal Protective Equipment • Universal Precautions

33. ENGINEERING CONTROLS • Design safety into the tools and work space organization • Engineering controls can: • Remove the risk of exposure to the hazard • Eliminate the hazard • Isolate the hazard
