Why Bloodborne Pathogens Matter at Work

A school nurse cleans a cut knee on the playground. A first aider in a warehouse helps a worker whose hand was cut by a box blade. A cleaner empties a bin in a clinic restroom and finds a used needle. A security officer separates two people in a fight, and one of them is bleeding. None of these people is a doctor. All of them may touch human blood as part of their job.

Blood can carry germs that cause serious disease. These germs are called bloodborne pathogens. The three that matter most at work are the hepatitis B virus (HBV), the hepatitis C virus (HCV) and the human immunodeficiency virus (HIV). They can pass from one person to another when infected blood, or certain other body fluids, enters the body through a needlestick, a cut, broken skin, or the eyes, nose or mouth.

In the United States, the Occupational Safety and Health Administration (OSHA) sets the rules that protect workers from this hazard. The rule is the Bloodborne Pathogens Standard, 29 CFR 1910.1030. CFR means the Code of Federal Regulations, the official book of federal rules.

Why the risk is real but manageable

Most exposures at work are preventable. The standard is built on a simple idea: treat all human blood as if it could be infected, use equipment and safe habits to keep it off your skin and out of your body, and act fast if an exposure happens. Hepatitis B can also be prevented with a vaccine, which your employer must offer to workers with occupational exposure at no cost to them.

By the end of this course you will be able to name the three main bloodborne pathogens, recognise the materials that carry them, follow the controls in an exposure control plan, use personal protective equipment (PPE) correctly, handle waste and spills safely, and know exactly what to do after a needlestick or splash.
