BLOODBORNE PATHOGENS
THE OCCUPATIONAL SAFETY AND HEALTH
ADMINISTRATION (OSHA) STANDARD
OSHA’S EXPECTATIONS
• Employer’s Duties– identify job risks
and classify – provide appropriate
training– provide a plan– provide appropriate
equipment
• Compliance
• Employee’s Duties– follow employer’s
plan– know job
classification– complete training– use equipment
provided by employer
• Compliance
OSHA REQUIRED INFORMATION
• Documents• General explanation of
bloodborne pathogens• Hepatitis B
immunization• Explanation of tasks
that may involve exposure
BLOODBORNE PATHOGENS DEFINED
• Disease-causing microorganisms that may be present in human blood or OPIM (other potentially infectious material)– Viruses– Bacteria– Parasites
MODES OF TRANSMISSION
• Puncture wounds or cuts
• Contact (touch, splash, or spray) with blood or OPIM on:– mucous membrane– non-intact skin
•cuts, abrasions, burns•acne, rashes•papercuts, hangnails
– contaminated sharps
RISK OF EXPOSURE
•Objective of BBP standard is to minimize or eliminate the hazard posed by work that may expose one to blood or OPIM
RISK OF EXPOSURE
• If a risk of exposure exists one should know:– if there is a way to
prevent infection– symptoms and course of
infection– availability of counseling – availability of post-
exposure treatment & follow-up
OCCUPATIONAL EXPOSURE INCIDENTS
• Occupational contact with blood or OPIM is considered an exposure incident
• If an exposure occurs:– wash with soap & water– report incident– document incident– seek “immediate” medical
evaluation– follow employer’s exposure
control plan
IMMEDIATE MEDICAL EVALUATION
• “Immediate” means prompt medical evaluation and prophylaxis
• An exact timeline cannot be stated• Time limits on effectiveness of
prophylactic measures vary depending on the infection of concern
REPORTING AN INCIDENT• Date and time of
incident• Job classification• Location in the
worksite where incident occurred
• Work practice being followed
• Procedure being performed
• PPE in use
Minimal Information to Report
MEDICAL EVALUATION POST EXPOSURE
• 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 health care provider
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
SPECIFIC BLOODBORNE PATHOGENS
• Definition• Signs and symptoms• Course of infection• Prevention and
control• Post-exposure prophy-
laxis and follow-up care
HIV DEFINED
• HIV is Human Immunodeficiency Virus
• HIV can cause acquired immune deficiency syndrome (AIDS)
• Risk of HIV infection from a puncture injury exposure to HIV infected blood is very low -- 0.3%
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 confirm if one is infected
COURSE OF INFECTION WITH HIV
• Incubation period from HIV infection to AIDS can be 8 to 10 years
• Varies greatly among individuals
HIV PREVENTION
• There is no vaccine to prevent HIV infection
• Follow Universal Precautions
HIV POST-EXPOSURE PROPHYLAXIS & FOLLOW-UP
• No cure for HIV infection
• Testing schedule for HIV antibodies– at time of exposure– at 3 months – at 6 months
• HIV antibodies usually become detectable within 3 months of infection
• Treatment requires health care provider
• OSHA requires treatment that meets most recent CDC guidelines
HCV DEFINED
• HCV is Hepatitis C Virus• It affects the liver• It is the most common chronic
bloodborne infection in US• 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
SIGNS & SYMPTOMS OF HCV
• Jaundice - yellow color to skin and whites of eyes
• Fatigue• Headache• Abdominal Pain• Loss of appetite• Nausea and vomiting
COURSE OF HCV INFECTION
• Incubation period averages 7 weeks
• Chronic liver disease may occur in 70% of those infected with HCV
HCV PREVENTION
• No vaccine exists to prevent HCV infection
• Follow Universal Precautions
HCV POST-EXPOSURE PROPHYLAXIS & FOLLOW-UP
• No cure for HCV • No post-exposure pro-
phylaxis recommended• Tests for HCV anti-
bodies & liver function recommended at time of exposure
• Tests should be repeated 4-6 months post exposure
• Treatment of HCV requires a health care provider
• OSHA requires treat-ment that meets most recent CDC guidelines
HBV DEFINED
• HBV is Hepatitis B Virus
• It affects the liver
• Prevalence of HBV infection among healthcare workers is 10 times greater than HCV infection
SIGNS & SYMPTOMS OF HBV
• Jaundice - yellow color to the skin and whites of eyes
•Fatigue•Headache•Abdominal Pain•Loss of appetite•Nausea and vomiting
COURSE OF HBV INFECTION
• Incubation period averages 12 weeks
•Most cases of HBV resolve without complications
•Chronic liver disease may occur in 6 to 7% of those infected with HBV
HBV PREVENTION
• A vaccine does exist to prevent HBV infection
• Employers are required to offer HBV vaccination HBV vaccination to employees covered under BBP standard. Debra Currier at Shiprock Administration Office 368-4984
Ext: 10103• Follow Universal Precautions
HBV POST-EXPOSURE PROPHYLAXIS & FOLLOW-
UP• No cure for HBV
infection• Post-exposure
prophylaxis should begin within 24 hours; no later than 7 days after exposure
• Exposed person should receive HBV vaccine
• Treatment requires health care provider
• OSHA requires treatment meet CDC’s most recent guidelines
HBV IMMUNIZATION
• Employees with routine occupational exposure to blood/OPIM have right to HBV vaccination at no personal expense
• Employee refusal established by signing HBV vaccination declination form
HBV VACCINATION SCHEDULE
• Vaccine given in 3 doses over 6 months– 1st on initial assignment– 2nd one month later– 3rd five months after 2nd dose
• Employer cannot require employee to use health insurance to cover test cost
• Pre-screening is not required• HBV is declining because of vaccine
use!
PREVENTION
• Work Practice Controls
• Personal Protective Equipment
• Universal Precautions
SHARPS CONTAINERS MUST BE:
• closable and puncture resistant
• leak proof• labeled or color-coded• functional• sufficient in number• easily accessible and main- tained in upright position• replaced per agency policy• DO NOT overfilled
HANDWASHING
• Readily available facilities
• Washing after removing PPE
• Using antiseptic hand cleanser when a sink isn’t readily available
HANDWASHING
•First roll out paper towel or have towel readily available so as not to touch other surfaces to reach it
HANDWASHING
•Turn on tap water and adjust temperature
•Use plenty of soap
HANDWASHING
•Wash hands using friction on all surfaces for at least 30 seconds
HANDWASHING
•Dry hands thoroughly
•DO NOT turn off the water yet
HANDWASHING
•Turn off tap with a dry part of the towel
•DO NOT touch surfaces with clean hands
CLEANING
• Clean work surfaces according to employer’s exposure control plan
• Use PPE and EPA-approved solution
• DO NOT take contaminated materials home to launder!
PERSONAL PROTECTIVE EQUIPMENT (PPE)
• Specialized clothing/equipment used for protection when risk of exposure exists
• Must prevent blood or OPIM from contaminating clothing or skin
• Must be available at no cost to employee
• Must be in appropriate sizes• Must be in good working condition• Must be properly maintained• Employee must be trained in proper use
TYPES OF PERSONAL PROTECTIVE EQUIPMENT
• Gloves• Masks• Eye shields• Gowns/aprons
LATEX GLOVES
• Medical products containing latex must be labeled
• Allergies to latex are increasing
• Substitutes for latex-containing materials must be made available
UNIVERSAL PRECAUTIONS
• Infection control approach that treats all human blood and certain body fluids as if they are known to contain bloodborne pathogens

custodians, certain special ed program personnel, playground duty personnel, health services personnel, and security personnel.
• Moderate Risk – Regular instructional program personnel, other special ed program personnel, school level office personnel, maintenance personnel, food services personnel, and special assignment personnel (e.g., counselors, librarians).
