OSHA Bloodborne Pathogens & Sharps Injury Prevention
Background & Significance
Annual Injury Statistics
Approximately U.S. health-care workers sustain needle-stick or other sharps injuries each year.
Such injuries expose workers to bloodborne pathogens (BBPs) that can cause serious illness or death.
Regulatory & Advisory Bodies
OSHA (Occupational Safety & Health Administration) – enforces the Bloodborne Pathogens Standard (29 CFR ).
NIOSH (National Institute for Occupational Safety & Health) – issues evidence-based recommendations.
CDC (Centers for Disease Control & Prevention) – publishes hand-hygiene and infection-control guidelines.
OSHA Bloodborne Pathogens Standard—Key Elements
Education / Training of staff regarding:
Nature of BBPs, modes of transmission, preventive strategies.
Procedures for post-exposure evaluation and follow-up.
Written Exposure Control Plan (ECP)
Must identify tasks & job classifications with occupational exposure.
Requires annual review and documentation of safer device evaluations.
Engineering Controls
Eliminate or isolate hazards at the source (e.g., needle-less systems).
Work Practice Controls
Alter the manner in which a task is performed to reduce exposure risk.
Personal Protective Equipment (PPE)
Gloves, masks, eye protection, gowns, etc.
Labels & Signs
Biohazard symbol and color coding on regulated waste and contaminated items.
Hepatitis B Vaccination & Post-Exposure Follow-Up
Free vaccine series offered to all at-risk employees.
Confidential medical evaluation, testing, counseling after exposures.
Defining Bloodborne Pathogens (BBPs)
BBPs = viruses, bacteria, or other microorganisms present in human blood that can cause disease.
Fluids considered potentially infectious:
Blood (whole blood, components, products).
Semen & vaginal secretions.
Amniotic, cerebrospinal, synovial (joint), pleural, pericardial, peritoneal fluids.
Saliva in dental procedures when blood is present.
Any unfixed human tissue or organ.
Major BBPs in health care:
HIV (Human Immunodeficiency Virus) → causes AIDS.
HBV (Hepatitis B Virus).
HCV (Hepatitis C Virus).
Less common yet serious agents:
HDV (Hepatitis D), Plasmodium spp. (malaria), Treponema pallidum (syphilis).
Modes of Transmission & Assumption of Universal Risk
Direct contact of infectious fluid with:
Non-intact skin (abrasions, cuts, rashes, burns).
Mucous membranes (eyes, nose, mouth).
Percutaneous injuries: needle sticks, puncture wounds, cuts from sharps.
Universal (Standard) Precaution Principle:
Assume every patient and all blood/body fluids are potentially infectious because carriers may be asymptomatic or unaware.
High-Risk Sharps & Common Injury Scenarios
Devices most frequently involved:
Hypodermic needles (injections).
Blood-collection needles.
Suture needles.
IV delivery system needles.
Injury-prone activities:
Giving injections, drawing blood, transferring fluids, recapping, disposing.
Engineering Controls & Safer Medical Devices
Purpose: remove the hazard before it reaches the worker.
Examples of safer needle designs:
Sliding sheath needles.
Hinged-cap needle guards.
Retractable or recessed needle systems.
Needle-less / blunt technologies:
Needle-less IV access ports for medication/fluid administration.
Blunted suture needles, surgical clips/staples for wound closure.
Other protective devices:
Plastic capillary/blood-collection tubes (prevent glass breakage).
Retractable or disposable scalpels & quick-release scalpel handles.
Catheter securement devices, advanced tapes/adhesives to avoid resticks.
Sharps Disposal Containers
Rigid, puncture-resistant, leak-proof, labeled with biohazard symbol.
Must be located at point of use and replaced when three-quarters full.
Work Practice Controls (Behavioral / Procedural Measures)
Hand Hygiene
Most effective infection-control measure.
Use alcohol-based hand rub or wash with soap & water per CDC guidelines.
Needle & Sharp Handling Rules
Do NOT bend, break, or remove needles by hand.
NEVER recap after use; if unavoidable, use one-handed scoop or mechanical device (tongs/forceps).
Activate safety features immediately after use and dispose promptly.
Waste & Linen Handling
Dispose sharps immediately; report overfilled containers.
Handle soiled linen minimally; wear gloves; place in labeled bags; double-bag if wet.
Environmental Controls
Separate specimen refrigerators from those for food, drinks, or meds.
Prohibit eating, drinking, applying cosmetics, or handling contact lenses in exposure areas.
Strict ban on mouth pipetting.
Spill & Breakage Response
Use tongs/brush & dustpan for broken glass; never bare or gloved hands.
Employ spill kits for blood/body fluid cleanup.
Disinfect with EPA-registered tuberculocidal solution.
Equipment Decontamination
Clean & disinfect instruments before reuse or service.
Label non-decontaminated parts so others can take precautions.
Disinfect work surfaces after contamination events and at shift end.
Personal Protective Equipment (PPE)
General Principles
Select PPE based on task & anticipated exposure level.
Remove before leaving the work area; dispose or send for reprocessing.
Gloves
Wear for any potential contact with blood or infectious materials.
Bandage pre-existing cuts before donning gloves.
Change between patients and between different procedures on same patient.
Use non-latex alternatives for latex-sensitive staff.
Masks & Eye / Face Protection
Surgical mask + goggles or face shield during activities with splash/spray risk.
Gowns / Aprons
Fluid-resistant gowns to protect skin and clothing.
Hand Hygiene Post PPE Removal
Mandatory to prevent secondary contamination.
Hazard Communication: Labels & Color Coding
Biohazard Symbol
Fluorescent orange-red background with contrasting lettering.
Items Requiring Labels/Color Coding
Containers of regulated waste, sharps, refrigerators/freezers holding specimens, specimen/transport containers, contaminated equipment.
Waste Disposal
Follow federal, state, and local regulations; use leak-proof, properly sealed bags/containers.
Hepatitis B Vaccination Program
Facility must offer vaccine series free of charge to all at-risk personnel.
Declination Form
If refused, employee must sign but retains right to accept later.
Efficacy & Significance
HBV vaccine yields long-term immunity and dramatically decreases occupational infection rates.
Post-Exposure Protocol (PEP)
Immediate First Aid
Wash skin with soap & running water; flush mucous membranes (eyes, mouth) with water.
Reporting
Notify supervisor without delay; early reporting enables timely prophylaxis.
Confidential Medical Evaluation & Follow-Up
Baseline & follow-up blood tests for HIV, HBV, HCV.
Counseling on transmission risk & prophylactic therapies (e.g., antiretrovirals within hours for HIV).
OSHA Sharps Injury Log
Required documentation: device type/brand, incident location, and event description.
Functions as surveillance tool to identify high-risk areas and justify engineering control upgrades.
Ethical, Professional, & Practical Implications
Ethical duty to protect oneself and prevent transmission to patients, coworkers, and family.
Compliance reduces organizational liability and fosters a culture of safety.
Integration with broader infection-control strategies (e.g., Standard & Transmission-Based Precautions).
Key Takeaways & Action Items
Adhere strictly to the Exposure Control Plan and update it annually.
Prioritize engineering controls—use the safest available devices.
Consistently practice hand hygiene and implement work-practice controls.
Choose and correctly use PPE for every procedure.
Participate in hepatitis B vaccination and understand post-exposure steps.
Maintain situational awareness: treat all blood/body fluids as infectious.
"Getting back to basics"—fundamental precautions remain the most powerful defense against occupational BBP exposure.
