Pathogens
Bloodborne Pathogens
• Microorganisms present in blood that cause
disease
– Hepatitis B virus (HBV)
– Human immunodeficiency virus (HIV)
• Contact pathogens in human blood or fluids or
contaminated materials through:
– eyes, mouth, mucus membranes, non-intact skin
Hazard Identification
• Identification of job classifications or tasks
where exposure exists
• Teaching or research labs using human fluids
• Administration of first aid
Hazard Identification
• Human blood and body fluids and their containers
• Hypodermic needles or blood drawing devices
• Towels, alcohol wipes and bandages containing
contaminated fluids
• Contaminated gloves
• Broken glass
8b
Exposure Control Plan
• Required whenever workers are exposed to
blood/potentially infectious materials on the
job
3a
Exposure Control Plan
• Schedules and methods of communication to
employees
• Engineering and work practice controls
• Personal protective equipment
• Housekeeping
• Procedures for evaluating an exposure incident
• Hepatitis B vaccination
• Post-exposure evaluation and follow-up
• Record keeping
3c
Communication to Employees
• Written plan
• Employee training
Engineering Controls
•
•
•
•
Use Universal Precautions
Eliminate hazards at the source
Reduce likelihood of exposure
Regularly check and maintain procedures to
remain effective
5a
Engineering Controls
Hand washing facilities
• Locations in building
• When to wash:
• Wash hands after removing gloves
• Wash hands after contact with blood or
potentially infectious fluids
• Use antiseptic cleansers in the field, then wash
as soon as possible
6a
Engineering Controls
Prohibited Activities
•
•
•
•
•
Eating
Drinking
Applying cosmetics or lip balm
Handling contact lenses
Touching mucus membranes
Personal protective equipment
• Best defense against unexpected hazards
• Use when potential exists for employee
exposure to infectious matter
• Proper selection of PPE is based on hazard
assessment
• Eye protection
• Bandages (for broken skin)
9a
Personal protective equipment
• Gloves (latex and non-latex, powder-less)
• Single-use gloves must be replaced if
contaminated, torn, punctured
• Never reuse single-use gloves
• Gloves must be discarded into biohazard
bags
Housekeeping
Handling Contaminated Items
• Biohazard Bag if soft and disposable
• Sharps Container if sharp or easily broken
to produce a sharp
• Autoclave if reusable and autoclavable
• 70% Alcohol if reusable and not
autoclavable
Housekeeping
Signs and Labels
• Used to warn of biohazards
• Biohazard symbol must:
• be printed in fluorescent orange or orange-red
• have lettering of a contrasting color
• Red bags or containers may be used as a
substitute for labels
Exposure incident response
• Exposure incidents involving:
•
•
•
•
eyes
mouth
other mucous membranes
broken skin
11b
Exposure incident response
• Apply first aid/emergency response
• Report and document the incident
• Arrange for immediate, confidential medical
evaluation, which:
• documents how the exposure occurred
• identifies and tests the source individual, if possible
• tests the exposed employee’s blood, if consent is
obtained
• provides counseling
• evaluates any reported illness
11a
Exposure incident response
• College must provide the medical
professional with relevant data to complete
the employee’s evaluation
• College must provide medical and postexposure evaluation procedures
Hepatitis B vaccine
• Hepatitis B can be transmitted by body fluid
• Preventative vaccine is available
• Post-exposure evaluation and follow-up will
be provided to anyone involved in an
exposure incident.
