What should be the first response if a healthcare worker is exposed to blood?

Washing the area thoroughly with soap and water is the most immediate and appropriate response when a healthcare worker is exposed to blood. This action serves to remove any potential pathogens from the skin's surface, thereby reducing the risk of infection. The mechanical action of washing helps to dislodge any contaminants and is vital in the first moments following an exposure.

While it is also important to report the incident to a supervisor or seek medical attention if necessary, these actions should be taken after the initial decontamination. Applying antiseptic solutions is generally not recommended as the first step because they may not effectively remove all contaminants compared to washing, and in some cases, they may irritate the skin if applied before washing. Immediate and thorough cleansing is critical in infection control protocols to ensure the health and safety of healthcare workers.
