FEDERAL: “Occupational Exposure to
Bloodborne Pathogens Standard”, Part
1910.1030, Title 29 Code of Federal
Regulations (effective date: 3/6/92)
WASHINGTON STATE: “Bloodborne
Pathogens Standard”, WAC 296-62-08001
(effective date: 5/26/92)
BLOODBORNE PATHOGENS
Infectious germs (bacteria and
viruses) that are present in human
blood/body fluids and can cause
disease in humans. These pathogens
include, but are not limited to,
Hepatitis B (HBV), Hepatitis C
(HCV), and human
immunodeficiency virus (HIV).
3
OCCUPATIONAL EXPOSURE
 Anticipated
contact with blood/body
fluids or other potentially infectious
materials on your skin or in your eye,
nose, or mouth during your job duty.
This includes a needle poke.
4
INFECTIOUS MATERIALS
 Blood
 All
body fluids (such as diarrhea and vomit)
since all can be potentially contaminated with
blood or infectious germs
 Viruses and bacteria that spread communicable
diseases through contact with bodily fluids.
 Semen/vaginal secretions

5
NSCC EXPOSURE CONTROL
PLAN
 Exposure
 Control
Determination
Measures
 Hepatitis
B Immunizations
 Exposure
evaluation/follow-up
 Training
and Education
 Record-keeping
6
Exposure Determination
 Risk
assessment associated with different
jobs - identification of tasks and potential
exposures -update as tasks change
 Classification I - tasks routinely involve a
potential for contact with BBP
 Classification II - tasks normally do not
involve exposure to BBP, but may require
performing unplanned Classification I tasks
 Tasks that involve no exposure to BBP
Control Measures
 Using
Universal Precautions
 Establishing appropriate Engineering
Controls
 Implementing appropriate Work Practice
Controls
 Personal Protective Equipment

THE HEPATITIS VIRUSES
 Six
known kinds of viral hepatitis: A-E, G
 They differ in how they are transmitted and
how they affect you.
 Hepatitis A and E: mild, spread through
contaminated foods or water. Not life
threatening.
 Hepatitis B, C, and D: spread through contact
with human blood or by sexual activity (B).
28
HEPATITIS A
 Transmission
29
through contaminated food or
water (fecal contamination).
 Symptoms: fatigue, abdominal pain, loss of
appetite, nausea, diarrhea.
 Does not destroy the liver.
 Not as common and is treatable by medicine.
 Vaccine available
 Prevention: proper hygiene, wash hands, use
gloves
HEPATITIS B
 Transmitted
through direct physical contact with
infected bodily fluids. Saliva is rare.
 Symptoms: Flu-like, loss of appetite, weak,
nausea, developing jaundice - dark urine
 Attacks the liver - cirrhosis, can have virus for
many years without knowing.
 Blood tests to determine if infected.
 A person’s antibodies will fight the virus and can
eliminate it from their system.
30
HEPATITIS B (cont.)
 Acute:
short term infection (less than 6 months)
 Chronic: long term infection (more than 6
months), your body fails to fight the virus.
 Around 80,000 new cases each year in U.S.
 6-10% of new cases become chronic carriers.
 1-1.25 million chronically infected Americans.
 Virus can live up to 7 days outside the body
 50-100 times more infectious than
HIV
31
HEPATITIS B (cont.)
 Vaccine:
safe and a 80-90% success rate.
Series of three injections - then titer is
checked
 Risk Groups: Drug users, homosexual males,
multiple sexual partners, infants born to
infected mothers, health care or child
care workers exposed to blood.
 Prevention: Avoid direct contact with bodily
fluids. Wear gloves when administering
first aid and during diaper changes.
32
Hepatitis B Vaccination Program
 Offered
to all covered employees at no cost
 Made available within 10 days of initial
assignment and is not mandatory
 Employees may decline vaccination and
accept at a later date - waiver form (App E)
 All employees exposed to blood or OPIM
on the job will be offered vaccination and
post exposure evaluation and treatment
HEPATITIS C
 Transmitted
through direct physical contact
with infected bodily fluids (also through
sexual contact - but not as common)
 Symptoms: Flu-like, loss of appetite, weak,
nausea, etc.
 Attacks the liver, can have virus for many
years without knowing.
 36,000 new cases per year in the U.S.
35
HEPATITIS C (cont.)
 <85%
of new cases become chronic carriers.
 3.9 million chronically infected Americans.
 No vaccine available yet.
 Hepatitis C is the “new” epidemic. Doctors are
just beginning to realize its impact.
 Virus is reaching epidemic proportions because
of the lack of testing available several years
ago when people were likely infected.
36
HEPATITIS C (cont.)
 Risk
Groups: Drug users, homosexual males,
infants born to infected mothers, health care or
child care workers exposed to blood.
 Prevention: Avoid direct contact with bodily
fluids. Wear gloves when administering first aid
and during diaper changes.
37
WHAT IS AIDS?
(Acquired Immune Deficiency Syndrome)
An
acquired illness of the immune system
which reduces the body’s ability to fight
specific types of infections and cancers
Caused by the Human Immunodeficiency
Virus (HIV)
The result of a long process that begins
with HIV infection (last stage of HIV)
18
At Higher Risk of Contacting HIV:
homosexual
males or people with
multiple sexual partners
IV drug users
children born to infected mothers
HIV TRANSMISSION
 Transmitted
through direct physical contact with
infected bodily fluids (most common transmission
is through sexual contact).
 Targets the immune system.
 Risk from one-time exposure: 0.2% (LOW
number of viruses present in blood), the virus can
only live outside of the human body- up to 24hours
High
risk groups: homosexual males or
people with multiple sex partners, drug users,
infants born to infected mothers.
19
HIV IS NOT TRANSMITTED BY:
 casual
contact
 hugging or kissing
 mosquitoes or insects
 donating or giving blood
 sharing food
 sharing telephones
 hot tubs or swimming
 being a friend
20
Some Statistics on AIDS
Cumulative # of cases/year
 United
States, 1981 - 372 cases
 United States, 1998 - 688,400 cases
 United States, 2000 - 753,907 cases total
 Washington State, 1982 - 20 cases
 Washington State, 1998 - 8,733 cases
 Washington State, 2000 - 9,387 cases total
21
You can’t tell by looking....!
(or initially, even by feeling!)
 It
is possible to be infected with HIV for
years even though you are
-looking fine
-feeling fine
-have no knowledge of the infection
AIDS
 Diagnosis
of AIDS is reserved for those
persons with life-threatening infections.
 AIDS definition includes:
-T-cell count of 200 or less
-Presence of specific illnesses or
conditions which meet criteria specified
in the AIDS case definition
 AIDS is the last stage of HIV infection
22
Prevention for all types of viruses:
 PRACTICE
UNIVERSAL PRECAUTIONS:
Protect from direct contact (e.g., wear
disposable gloves; use condoms; don’t share
needles) with ANY blood or other potentially
infectious materials. ALWAYS assume that
such material is infectious.
 PRACTICE GOOD PERSONAL HYGIENE
Wash, wash, wash, wash your hands.
 FOLLOW GOOD HOUSEKEEPING
23
ADMINISTERING FIRST AID
 Follow
Universal Precautions.
 Treat all body fluids as if infectious.
 Wear GLOVES (and other personal
protective equipment, mask with one way
valve if administering CPR).
 Wash hands after removing gloves!
28
In Summary: Avoid BBP Exposures!
 Practice
Universal Precautions
 Monitor Personal Hygiene
 Practice Good Housekeeping
 Dispose of Wastes Properly
