Bloodborne Pathogens Defined

Bloodborne pathogens can cause serious and sometimes deadly diseases. To reduce risk, OSHA’s bloodborne pathogens standard applies to anyone with occupational exposure to blood or other potentially infectious materials, requirements that are easy to meet with online bloodborne pathogens training.  

This blog will delve into the definition of bloodborne pathogens, common examples, how they’re transmitted, and more.  

What Are Bloodborne Pathogens and How Are They Transmitted?  

A bloodborne pathogen (BBP) is any disease-causing organism that passes from one entity to another through blood or other potentially infectious materials (OPIM). The symptoms of bloodborne diseases vary by the type of infection, but these diseases sometimes present initially with flu-like symptoms, if they’re symptomatic at all. 

Bloodborne pathogens examples in the workplace include Hepatitis B, Hepatitis C, and HIV are the most common bloodborne diseases. Other less common examples include Ebola, Dengue, and other viral hemorrhagic fevers (VHFs). 

How Are Bloodborne Pathogens Transmitted? 

Bloodborne pathogens are transmissible through direct contact with blood or OPIMs, which can include: 

• Blood 

• Blood serum 

• Vaginal secretions 

• Semen 

• Cerebrospinal fluid 

• Joint capsule or organ fluids, including pleural and peritoneal fluids 

• Amniotic fluid 

Infections can be passed when any of these fluids make contact with either broken/damaged skin (including sunburn, acne, or chapped skin) or a mucous membrane (like the eyes, nose, mouth, and genitals). That can include the inhalation of aerosolized infectious material. 

Contact with unbroken, healthy skin is low-risk but should be avoided since not all skin damage is readily apparent. 

Other bodily fluids, including saliva, urine, feces, and sweat, are considered “low risk” for the transmission of common bloodborne pathogens. However, precautions should still be taken, especially considering the discovery that these fluids can transmit certain hemorrhagic fevers. 

From a practical standpoint, this means that bloodborne diseases are often passed through unprotected sexual contact, needles, or other sharps. However, bloodborne infections can also be passed from mothers to babies during pregnancy or birth. 

OSHA’s Bloodborne Pathogen Standard 

OSHA published the first bloodborne pathogen standard in 1991. The current standard can be found under 29 CFR 1910.1030. It outlines the requirements for at-risk professionals, including healthcare workers, for preventing bloodborne pathogen exposure in the workplace. 

OSHA requires workplaces with potential BBP exposure to take certain measures, including: 

• Develop an exposure control plan and meet OSHA exposure control plan requirements  

• Create a list of all job classifications with occupational exposure to BBP 

• Use engineering controls and work practices to eliminate or minimize exposure 

• Require universal precautions to prevent contact with blood/OPIM 

• Provide, maintain, and require the use of appropriate personal protective equipment 

• Set schedules and protocols for decontamination of the work area 

• Provide proper containers for sharps and other regulated waste 

• Train employees with occupational exposure annually 

PPE Requirements for Bloodborne Pathogen Exposure 

According to OSHA’s Bloodborne Pathogen standard, the exact PPE you choose for any given task should be appropriate to the level and type of expected exposure. This means the PPE requirements for bloodborne pathogen exposure will depend on the circumstances.  

Gloves are always a basic requirement since it’s reasonable to expect that a worker performing a risky task will have hand contact with blood, OPIM, or contaminated surfaces. 

Goggles and face masks (and/or face shields) are necessary whenever a task poses a risk of splashes, sprays, spatters, or droplets of blood or OPIM to the eyes, nose, and mouth. 

Gowns, aprons, lab coats, and other protective clothing should be used when exposure to the body is a risk, including surgery, autopsy, and BBP research facilities. When “gross contamination” is expected, workers need surgical caps, hoods, and shoe covers/booties. 

PPE should be removed after the task is complete and disposed of or decontaminated. Never wear used BBP PPE outside the work area.  Always be sure to maintain good housekeeping practices to keep worksites clean and sanitary, including prompt cleanup of spills, routine disinfection of work surfaces, and proper storage of clean PPE. Employers should also keep written procedures for cleaning and decontaminating work surfaces that specify approved disinfectants, contact times, cleaning frequency, and who is responsible for each step. 

How to Prevent Exposure to Bloodborne Pathogens: Universal vs. Standard Precautions  

You’ve probably heard both terms used when discussing infection control. Each plays a role in preventing exposure to infectious materials. While they sound similar, universal and standard precautions have different origins and applications in workplace safety. Let’s take a closer look at both.  

Universal Precautions (UP) 

Universal Precautions is an older CDC concept referenced in OSHA’s Bloodborne Pathogens Standard. It means treating all blood and other potentially infectious materials (OPIM) as if they are infectious and applying barrier protections accordingly. 

Key steps under Universal Precautions include: 

• Treat all blood and OPIM as potentially infectious, regardless of the source. 

• Wear appropriate PPE—such as gloves, masks, eye protection, and gowns—whenever there’s a risk of exposure to blood or OPIM. 

• Use safe work practices, such as proper sharps handling and disposal in puncture-resistant containers. 

• Avoid eating, drinking, or touching your face in areas where exposure could occur. 

• Clean and decontaminate surfaces and equipment immediately after contact with blood or OPIM, following your written exposure control procedures. 

Universal Precautions focus specifically on blood and OPIM, not all body fluids. 

Standard Precautions (SP) 

Standard Precautions represent the modern, broader approach developed by the CDC. They combine Universal Precautions and Body Substance Isolation (BSI) to cover all body fluids, secretions, and excretions (except sweat), as well as nonintact skin and mucous membranes. 

Core elements of Standard Precautions include: 

• Hand hygiene before and after every patient contact or task. 

• Use of PPE based on the type of exposure risk (gloves, masks, eye protection, gowns). 

• Respiratory hygiene and cough etiquette to prevent droplet spread. 

• Safe injection practices and proper sharps handling/disposal. 

• Environmental cleaning and disinfection of work surfaces and shared equipment. 

• Proper handling of laundry and regulated waste. 

• Implementation of written procedures for cleaning and decontaminating surfaces to maintain a sanitary work environment. 

In practice, OSHA’s Bloodborne Pathogens Standard still references “Universal Precautions,” but today’s healthcare and allied health settings apply “Standard Precautions” as the baseline for infection control. 

“Universal Precautions” is an older CDC/OSHA term. It means treating all blood and certain body fluids as potentially infectious and applying barrier protections accordingly.   

“Universal precautions” is the idea that certain protective practices, like wearing gloves, must be implemented whenever an activity carries the risk of BBP transmission. You must assume that all bodily fluids and all sites, like open wounds and mucous membranes, contain pathogenic microorganisms. 

However, “Standard Precautions” is the modern, broader approach. It builds on universal precautions but extends protection to all patients and all body fluids or tissues (not just blood), incorporating hand hygiene, respiratory etiquette, safe injection practices, environmental cleaning, and more.  

In practice, OSHA’s Bloodborne Pathogens Standard still references universal precautions, but today’s health settings apply standard precautions as the baseline for infection control.  

For clinical and allied health roles, the takeaway is: use standard precautions consistently, regardless of perceived risk, and layer on additional precautions as needed (e.g., transmission-based precautions).  

Post-Exposure Protocol  

Despite your best efforts to follow safety procedures, exposure incidents can still occur. Knowing what to do in those first few moments can make all the difference. Here’s what to do immediately after a possible exposure: 

1. Stop the procedure and contain the area.  

2. Cleanse the site. Use soap & water for cuts; flush mucous membranes with water or saline.  

3. Report the incident. Tell your supervisor or safety officer and complete the exposure report.  

4. Determine source status. Find out if the source is known and whether they’ve been tested for HIV, HBV, and HCV.  

5. Seek medical evaluation. Get baseline labs and determine whether post-exposure prophylaxis (PEP) is needed.  

6. Follow up. Return for follow-up testing (e.g., at 6 weeks, 3 months, 6 months) and counseling.  

7. Review prevention. Analyze how the exposure occurred and adjust policies, equipment, or training to prevent future incidents. 

Bloodborne Pathogen Training Requirements 

As part of the bloodborne pathogen standard, OSHA requires employers to provide yearly training to employees with occupational exposure. 

BBP training must include: 

• An explanation of the BBP standard 

• The epidemiology and symptoms of bloodborne diseases 

• The modes of transmission 

• The employer's exposure control plan  

• How to recognize tasks that may involve exposure to blood/OPIM 

• The use and limitations of engineering controls, work practices, and PPE 

• How to select, find, use, remove, handle, decontaminate, and dispose of PPE 

• What to do and who to contact in an emergency involving blood/OPIM 

• Post-exposure protocol and mandatory follow-up 

Who Needs Bloodborne Pathogen Training? 

The bloodborne pathogen standard and its training requirement apply to anyone at risk of occupational exposure to blood and OPIM. 

This list is longer than you’d think! Professions that need BBP training include: 

• Healthcare workers 

• Janitorial, laundry, and housekeeping staff 

• Law enforcement 

• Blood/tissue bank staff and volunteers 

• Medical equipment technicians 

• Teachers, school nurses, and other school employees 

• Morticians and other funeral home employees
