Bloodborne Pathogens

OSHA, Your Rights, and the Employer's Duty

The Occupational Safety and Health Act of 1970 created OSHA to assure safe and healthful working conditions. Under the General Duty Clause (§5(a)(1)), every employer must furnish a workplace free from recognized hazards likely to cause death or serious harm, and under §5(b) employees must comply with the safety and health standards that apply to their own conduct. The General Duty Clause fills the gaps where no specific standard exists — for example, an employer who knows that an unguarded floor opening is likely to cause a fall has a duty to address it even without a citation-by-number.

You have the right to: training in a language and vocabulary you understand, information about the hazards you work with (container labels and Safety Data Sheets), access to your own exposure monitoring and medical records, and the ability to file a complaint or request an OSHA inspection. Critically, you can exercise these rights without retaliation — an employer may not fire, demote, or otherwise punish you for raising a safety concern. If you believe you were retaliated against, you can file a whistleblower complaint with OSHA, generally within 30 days.

Employers must record serious work-related injuries and illnesses on the OSHA 300 log (29 CFR 1904) and post the annual summary where workers can see it. They must also report any work-related fatality to OSHA within 8 hours, and any inpatient hospitalization, amputation, or loss of an eye within 24 hours. This program documents your training and completion as part of that broader safety and recordkeeping system.

The Standard & the Exposure Control Plan

The Bloodborne Pathogens standard protects workers who have a reasonably anticipated risk of contact with blood or other potentially infectious materials (OPIM) while doing their jobs. It applies broadly — to nurses, phlebotomists, dental assistants, EMTs, firefighters, housekeeping and laundry staff handling soiled linens, and anyone whose duties may bring them into contact with blood. The first protection the standard requires is planning: your employer must develop and maintain a written Exposure Control Plan that identifies the at-risk job classifications and tasks and documents the controls used to reduce exposure.

The Exposure Control Plan is a living document, not a binder that sits on a shelf. It must be reviewed and updated at least annually and whenever new tasks, procedures, or safer devices change the exposures employees face — for example, when a clinic adopts a new self-sheathing IV catheter. The plan must also reflect input from non-managerial frontline staff on choosing safer medical devices, and it must be accessible to employees who ask to see it.

Training reinforces the plan. You must receive bloodborne pathogens training at the time of initial assignment to tasks with exposure and at least once every year thereafter. The training must be delivered by a person knowledgeable in the subject matter, and you must have the opportunity to ask questions and get answers directly — which is why Prime pairs this content with a trainer-of-record. Before you move on, make sure you know where your Exposure Control Plan is kept and who to ask about your site-specific procedures.

Bloodborne Diseases & Modes of Transmission

Bloodborne pathogens are infectious microorganisms carried in human blood that can cause disease. The three of greatest occupational concern are Hepatitis B (HBV), Hepatitis C (HCV), and HIV. HBV and HCV attack the liver and can lead to chronic infection; HIV attacks the immune system. HBV is notably hardy — it can survive in dried blood on a surface for days — which is why a small, unnoticed exposure can still pose a risk.

Workplace transmission happens when infected blood or OPIM enters your body. The main routes are a needlestick or other sharps injury, a splash of blood or fluid onto mucous membranes (the eyes, nose, or mouth), and contact with non-intact skin such as a cut, abrasion, or dermatitis. OPIM — other potentially infectious materials — includes fluids like semen, vaginal secretions, cerebrospinal, synovial, and amniotic fluid, any body fluid visibly contaminated with blood, unfixed human tissue, and HIV/HBV laboratory cultures. A paramedic suctioning an airway, a nurse drawing blood, and a housekeeper handling a soiled dressing are all examples of tasks where these routes come into play.

Because you cannot tell by looking whether blood or fluid is infectious, the standard requires Universal Precautions: treat all human blood and OPIM as if they are known to be infectious. The most effective prevention for HBV is vaccination, and your employer must offer the HBV vaccine series free of charge to workers with occupational exposure, within 10 working days of assignment. You may decline, but you can request and receive the vaccine later at any time while you remain covered.

Personal Protective Equipment (PPE) Fundamentals

Under 29 CFR 1910.132, employers must assess the workplace to determine what PPE is needed, provide it (in most cases at no cost to the worker), and train each worker on what PPE is necessary, when and how to wear it, its limitations, and proper care, maintenance, useful life, and disposal. The hazard assessment must be documented through a written certification identifying the workplace evaluated and the person who performed it.

Categories track the body part or exposure they address: eye and face protection (1910.133), head protection (1910.135), hearing protection, respiratory protection (1910.134), hand protection with the glove material matched to the chemical or mechanical hazard (1910.138), foot protection (1910.136), and full-body protection. The wrong choice creates a false sense of safety — a nitrile glove may resist one chemical while dissolving in another, and a respirator that does not seal to the face offers little protection.

PPE only works when it fits and is worn correctly for the specific hazard. Inspect PPE before each use and remove damaged equipment from service rather than risking a failure mid-task. NOTE: hands-on fit and skills components (for example, respirator fit testing under 1910.134) are completed in person with your employer; this module covers the knowledge foundation, not the physical fit test.

Controls, PPE & Safe Work Practices

The standard requires controlling exposure in a specific order. Engineering controls come first because they remove or isolate the hazard at the source: sharps disposal containers, self-sheathing or retractable needles, blunt-tip sutures, and splash guards. These devices must be examined and maintained on a regular schedule. Where exposure remains, work-practice controls change how the task is performed — never recapping needles by hand, never bending or shearing them, washing hands immediately after glove removal, and prohibiting eating, drinking, applying cosmetics, or handling contact lenses in areas where exposure is possible.

Personal protective equipment is the final layer, used when engineering and work-practice controls do not eliminate exposure. PPE includes gloves, gowns, face shields or masks with eye protection, and resuscitation devices, and your employer must provide it, clean it, repair it, and replace it at no cost to you. Choose the level of protection the task demands — a phlebotomist may need only gloves, while a first responder managing an arterial bleed needs gloves, a fluid-resistant gown, and eye and face protection. Remove PPE before leaving the work area, and remove it carefully so contaminated surfaces do not touch your skin or clothing.

Contaminated sharps go immediately into containers that are closable, puncture-resistant, leak-proof on the sides and bottom, and labeled or color-coded; do not overfill them. Biohazard warning labels are fluorescent orange or orange-red and must appear on containers of regulated waste, contaminated laundry, and refrigerators or freezers holding blood or OPIM. After handling contaminated items and after removing gloves, wash your hands with soap and running water — or use an approved antiseptic hand cleaner until you can get to a sink.

If an Exposure Incident Occurs

An exposure incident is a specific contact with blood or OPIM that results from performing your duties — a needlestick or cut from a contaminated sharp, a splash to the eyes, nose, or mouth, or contact with non-intact skin. Knowing in advance what counts as an incident helps you act without hesitation when one happens.

Take immediate action in this order. First, provide first aid: wash a needlestick or wound with soap and running water, and flush a splashed eye, nose, or mouth with water or saline for several minutes. Next, report the incident to your supervisor right away, following your site's specific reporting procedure — for example, a nurse stuck while disposing of a syringe notifies the charge nurse and occupational health, while a firefighter exposed on a call reports to the incident commander and the department's designated officer. Do not delay to finish the task.

Once reported, your employer must make a confidential medical evaluation and follow-up available to you at no cost. This includes documenting the route and circumstances of exposure, identifying and testing the source individual where feasible and permitted by law, testing your blood with your consent, offering post-exposure prophylaxis when medically indicated, and providing counseling and evaluation of any reported illness. Timing is critical: prophylaxis for HIV and HBV is most effective when started quickly, often within hours, so rapid reporting directly affects how well you can be protected. You are entitled to a copy of the evaluating healthcare professional's written opinion.

Final Assessment

This assessment is a comprehensive check across the full course: the structure of the standard and the Exposure Control Plan, the primary bloodborne diseases and how they are transmitted, the hierarchy of engineering controls, work-practice controls, and PPE, and the correct response to an exposure incident.

Answer each item based on what the standard requires and the practices covered in the lessons. A passing score, identity verification, and the availability of a live trainer to answer questions are required for course completion and certification. If any topic feels unclear, return to the relevant lesson or raise it with your trainer-of-record before completing.
