1. Blood borne Pathogens

2. What Are Bloodborne Pathogens?
Bloodborne pathogens are microorganisms such as viruses or bacteria that are carried in blood and can cause disease in people. 2

3. Training
The employer shall train each employee with occupational exposure in accordance with the requirements:
At the time of initial assignment to tasks where occupational exposure may take place
At least annually thereafter
Provide additional training when changes such as modifications of tasks or procedures or institution of new tasks or procedures affect the employee’s occupational exposure (additional training may be limited to addressing the new exposures created)
Company Overview

4. Types of Bloodborne Pathogens
Bloodborne pathogens include:
Malaria
Syphilis
Brucellosis - contact with animals (i.e. dairy)
Hepatitis B (HBV) and Hepatitis C (HCV)
Human Immunodeficiency Virus (HIV) 3

5. Human Immunodeficiency Virus (HIV)
Workplace Concerns
Hepatitis B (HBV)
Hepatitis C (HCV)
Human Immunodeficiency Virus (HIV)

6. is transmitted primarily through "blood to blood" contact
Hepatitis B (HBV)…
is a virus that causes infection and inflammation of the liver
is transmitted primarily through "blood to blood" contact
can lead to serious conditions such as cirrhosis & liver cancer
can survive in dried blood for up to seven days 4

7. Hepatitis B (HBV)… There is no "cure" or specific treatment for HBV
Many people develop antibodies to fight the disease which may prevent future infection 5

8. Hepatitis B (HBV)…
Vaccines are available to those who’s job requires them to be exposed to bloodborne pathogens
Typically the vaccines are a series of 3 shots and then blood work to determine if the vaccine took (you developed antibodies)
However, the licensed health care provider (LHCP) will determine the course of action that needs to be taken for each employee.
Company Overview

9. Hepatitis B (HBV)… Vaccines are provided by the company
Employees who decline to take the vaccine must sign a declination form
These employee can come back at any time and request the vaccine
Company Overview

10. Hepatitis B (HBV)…
Incubation period is 30 – 180 days. Initial symptoms can include:
Mild flu-like symptoms
Fatigue
Possible stomach pain
Loss of appetite
Nausea
Symptoms can last 3-10 days. This is followed by jaundice or dark urine. 6

11. What is Hepatitis C? (HCV)
Hepatitis C is a disease of the liver caused by the hepatitis C virus. HCV is spread by contact with the blood of a hepatitis C if you:
were notified that you received blood from a donor who later tested positive for hepatitis C
have ever injected illegal drugs, even if you experimented a few times many n infected person. You may be at risk for years ago
received a blood transfusion or solid organ transplant before July, 1992

12. HCV cont’d…
received a blood product for clotting problems produced before 1987
have ever been on long-term kidney dialysis
have evidence of liver disease (e.g., persistently abnormal ALT levels)
There is no vaccine for Hepatitis C Virus.

13. Human Immunodeficiency Virus (HIV)
AIDS, or acquired immune deficiency syndrome, is a disease caused by a virus called the human immunodeficiency virus, or HIV.
It may be many years before AIDS actually develops.
HIV attacks the body's immune system, weakening it so that it cannot fight other deadly diseases. AIDS is a fatal disease, and while treatment for it is improving, there is no known cure. 9

14. HIV and Direct Contact
The HIV virus is very fragile and will not survive very long outside of the human body. It is primarily of concern to employees providing first aid or medical care in situations involving fresh blood or other potentially infectious materials. 10

15. HIV Symptoms Symptoms of HIV infection can vary, but often include:
Weakness
Fever
Sore throat
Nausea
Headaches
Diarrhea
White coating on the tongue
Weight loss
Swollen lymph glands 11

16. Some Workers Who are at Risk
Physicians, nurses and emergency room personnel
Orderlies, housekeeping personnel, and laundry workers
Dentists and other dental workers
Laboratory and blood bank technologists and technicians
Medical examiners and morticians
Law enforcement personnel and firefighters
Paramedics and emergency medical technicians
Anyone providing first-response medical care
Medical waste treatment employees
Home healthcare workers
The scope of the Bloodborne Pathogens standard is not limited to employees in these jobs. The hazard of exposure to infectious materials affects employees in many types of industries and is not restricted to the health care industry.
Discuss the jobs/tasks at your site where there could be a exposure to a bloodborne pathogen.

17. Bloodborne Pathogen Transmission
Bloodborne pathogens are transmitted through contact with infected human blood and other body fluids such as:
Semen
Vaginal secretions
Cerebrospinal fluid (brain & spine)
Synovial fluid (joints)
Pleural fluid (lungs)
Peritoneal fluid (heart)
Amniotic fluid (baby)
Saliva with visible blood (in Dental setting) 12

18. Bloodborne Pathogen Transmission
In the occupational setting, transmission is by percutaneous injuries (needlesticks/sharp puncture or cut), mucous membrane and non-intact skin exposure to contaminated blood or other potentially infectious materials (OPIM). HCV is transmitted by percutaneous exposure to contaminated blood and plasma derivatives.
Company Overview

19. Skin Provides a Barrier
Unbroken skin forms an impervious barrier against bloodborne pathogens. However, infected blood can enter your system through:
Open sores
Cuts
Abrasions
Acne
Any sort of damaged or broken skin such as sunburn or blisters 13

20. Mucous Membranes Eyes Nose Mouth
Bloodborne pathogens may also be transmitted through the mucous membranes of the:
Eyes
Nose
Mouth 14

21. Risk of Infection After Occupational Exposure
Not all the bloodborne pathogens carry the same risk of infection from an occupational exposure. Frequency in patient population, the ability of the virus to survive on environmental surfaces and the amount of virus present in the body fluid, all impact the risk of acquiring infection, if exposed. The following table demonstrates infection risk from a percutaneous exposure to HBV, HCV, and HIV.
Risk of Infection From Percutaneous Exposure
Virus
Viral particles/mL of serum/plasma
Infection Risk
HBV
30%
HCV 3%
HIV
0.3%
Company Overview

22. Signs & Labels
Warning labels must be placed on containers of regulated waste, refrigerators and freezers containing blood or other potentially infectious material; and other containers used to store, transport, or ship blood or other potentially infectious materials. 15

23. What is Regulated Waste?
Any liquid or semi-liquid blood or other potentially infectious materials
Contaminated items that would release blood or other potentially infectious materials in a liquid or semi-liquid state if compressed
Items that are caked with dried blood or other potentially infectious materials 16

24. Hierarchy Engineering Controls Administrative Controls
These controls reduce employee exposure by either removing the hazard or isolating the hazard.
Administrative Controls
These controls reduce the likelihood of exposure by altering how a task is performed. Examples include:
Wash hands after removing gloves and as soon as possible after exposure
Do not bend or break sharps
No food or smoking in work areas
Company Overview

25. Hierarchy
PPE
Specialized clothing or equipment worn by employees for protection against infectious materials:
Must be properly cleaned, laundered, repaired, and disposed of at no cost to employees
Must be removed when leaving area or upon contamination
Company Overview

26. How Should Any Type of Exposure Be Handled?
Universal Precautions- an approach to infectious control in which all human blood and most bodily fluids are treated as infectious materials
Types of PPE
Face shield
Barrier masks
Gloves 16 26

27. Emergencies
In an emergency situation, call for professional medical help and notify your immediate supervisor
Only provide emergency treatment to the level of your training (after medics have been summoned) and ONLY IF proper PROTECTIVE EQUIPMENT (i.e. barrier mask, gloves, etc) is available.
Remember to treat all injured victims using Universal Precautions. Allow medical staff to clean up and dispose of any contaminated waste materials. 17

28. Post Exposure Follow-Up
Knowing the right steps to take after an exposure incident is critical in reducing the likelihood of acquiring a bloodborne pathogen.
Immediately after any exposure incident:
Wash the exposed are with soap and water; if the exposure involves the eyes, you should flush with tap water
Report the incident to your supervisor and complete an incident report
Report the incident to your site’s Safety Specialist
Follow any instructions given for treatment
