Lesson 8.2 — Bloodborne Pathogens & OSHA

Lesson Overview

Healthcare workers, including Home Health Aides (HHAs) and Certified Nursing Assistants (CNAs), may come into contact with blood and body fluids during patient care activities. Exposure to bloodborne pathogens can place caregivers at risk for serious infectious diseases.

The Occupational Safety and Health Administration (OSHA) established the Bloodborne Pathogens Standard to protect healthcare workers from exposure to infectious materials in the workplace. Caregivers must understand how bloodborne pathogens spread, how to prevent exposure incidents, and how to respond properly if exposure occurs.

This lesson teaches caregivers about OSHA standards, exposure control plans, blood exposure prevention, needle stick procedures, and infection safety practices.

Learning Objectives

By the end of this lesson, learners will be able to:

  • Understand OSHA Bloodborne Pathogen standards
  • Identify common bloodborne pathogens
  • Prevent exposure incidents
  • Follow the agency exposure control plan
  • Respond appropriately to blood exposure incidents
  • Understand needle stick injury procedures
  • Maintain OSHA compliance during patient care

What Are Bloodborne Pathogens?

Bloodborne pathogens are infectious microorganisms found in human blood and certain body fluids that can cause disease in humans.

Common Bloodborne Pathogens Include:

Hepatitis B (HBV)

A virus that affects the liver and may cause serious illness.

Hepatitis C (HCV)

A liver infection spread through contaminated blood exposure.

Human Immunodeficiency Virus (HIV)

A virus that weakens the immune system.

Bloodborne pathogens may spread through:

  • Blood exposure
  • Needle sticks
  • Contact with contaminated sharps
  • Contact with open wounds or mucous membranes

OSHA Bloodborne Pathogen Standard

OSHA created the Bloodborne Pathogen Standard to help protect workers from occupational exposure to blood and body fluids.

The OSHA standard requires:
✅ Employee training
✅ Exposure control plans
✅ PPE use
✅ Safe sharps handling
✅ Hepatitis B vaccination availability
✅ Exposure reporting procedures

OSHA standards help reduce workplace injuries and infections.

Exposure Control Plan

The agency maintains a written Exposure Control Plan that outlines procedures for:

  • Preventing exposure incidents
  • Using PPE properly
  • Reporting exposures
  • Handling contaminated materials
  • Cleaning spills safely
  • Managing sharps safely

Caregivers must understand and follow the agency Exposure Control Plan at all times.

Universal / Standard Precautions

Caregivers should treat:

  • Blood
  • Body fluids
  • Open wounds
  • Contaminated materials

as potentially infectious.

Standard precautions should ALWAYS be followed regardless of patient diagnosis.

Preventing Exposure Incidents

Caregivers can reduce exposure risks by:
✅ Performing hand hygiene
✅ Wearing gloves and PPE appropriately
✅ Following safe sharps procedures
✅ Cleaning contaminated surfaces properly
✅ Avoiding direct contact with blood or body fluids
✅ Disposing of contaminated materials safely

Personal Protective Equipment (PPE)

PPE helps protect caregivers from exposure.

PPE May Include:

  • Gloves
  • Masks
  • Eye protection
  • Face shields
  • Gowns

Caregivers should use PPE whenever exposure to blood or body fluids is possible.

Glove Use

Gloves should be worn when:
✅ Assisting with wound care
✅ Handling blood or body fluids
✅ Providing personal care
✅ Cleaning contaminated items

Caregivers should:
✅ Change gloves between tasks
✅ Remove gloves safely
✅ Wash hands immediately after glove removal

Sharps Safety

Sharps include:

  • Needles
  • Lancets
  • Razors
  • Broken glass
  • Other sharp medical instruments

Improper sharps handling may cause serious injuries and infections.

Needle Stick Prevention

Caregivers should NEVER:
❌ Recap needles
❌ Bend needles
❌ Break needles
❌ Dispose of sharps in regular trash
❌ Handle sharps carelessly

Sharps should be disposed of immediately in approved sharps containers.

Needle Stick Procedures

If a needle stick injury occurs:

Step 1 — Wash Area Immediately

Use soap and water.

Step 2 — Notify Supervisor Immediately

Report the exposure according to agency policy.

Step 3 — Seek Medical Evaluation

Follow agency exposure procedures promptly.

Step 4 — Complete Incident Documentation

Document the exposure accurately.

Immediate reporting is essential for proper treatment and follow-up.

Blood & Body Fluid Exposure Procedures

If blood or body fluids contact:

  • Skin
  • Eyes
  • Mouth
  • Open wounds

Caregivers should:
✅ Wash affected area immediately
✅ Flush eyes or mucous membranes with water
✅ Notify supervisor immediately
✅ Follow exposure control procedures
✅ Seek medical evaluation if directed

Cleaning Blood & Body Fluid Spills

Caregivers should:
✅ Wear gloves
✅ Use approved disinfectants
✅ Follow agency cleaning procedures
✅ Dispose of contaminated materials properly

Never clean blood spills without appropriate protection.

Hepatitis B Vaccination

OSHA requires employers to offer the Hepatitis B vaccine to employees at risk for occupational exposure.

The vaccine helps protect caregivers from Hepatitis B infection.

Caregivers should:
✅ Understand vaccine availability
✅ Follow agency vaccination procedures

OSHA Compliance Responsibilities

Caregivers are responsible for:
✅ Following OSHA safety standards
✅ Using PPE correctly
✅ Reporting exposures immediately
✅ Participating in required training
✅ Following safe work practices

Failure to follow OSHA procedures may place caregivers and patients at risk.

Exposure Incident Reporting

Exposure incidents must be reported immediately.

Examples include:

  • Needle sticks
  • Blood splashes
  • Contact with body fluids
  • Sharps injuries

Prompt reporting helps:
✅ Reduce infection risk
✅ Ensure medical treatment
✅ Maintain workplace safety
✅ Support OSHA compliance

Real-Life Scenarios

Scenario 1 — Blood Exposure

A caregiver accidentally touches blood while assisting with wound care.

Correct Response:

✅ Remove gloves safely
✅ Wash hands immediately
✅ Follow agency exposure procedures if skin contact occurred

Scenario 2 — Needle Stick Injury

A caregiver is accidentally stuck by a used lancet.

Correct Response:

✅ Wash area immediately
✅ Notify supervisor immediately
✅ Seek medical evaluation
✅ Complete incident report

Scenario 3 — Contaminated Surface

A blood spill occurs in the patient bathroom.

Correct Response:

✅ Wear gloves and PPE
✅ Use approved disinfectant
✅ Dispose of contaminated materials safely
