What should the RT do after an arterial blood sample is spilled on the lab counter?

When an arterial blood sample is spilled on a lab counter, the most appropriate action is to disinfect the area with a bleach solution. This procedure is crucial because arterial blood can contain potentially infectious pathogens, and it's essential to decontaminate surfaces to prevent exposure and ensure a safe working environment.

Using a bleach solution effectively kills viruses and bacteria that may be present in blood. Clorox bleach, when diluted appropriately, can be an effective disinfectant on surfaces. This step not only safeguards the health of the staff working in the laboratory but also adheres to standard safety protocols for handling biohazardous materials.

Other methods, such as simply washing with soap and water, may not eliminate all pathogens present in the blood. Covering the spill with a paper towel does not adequately address the contamination risk, as it may allow pathogens to remain on the surface. Leaving the clean-up to janitorial staff without prior disinfection could also expose them to biohazardous material, which is not advisable. Therefore, disinfecting with a bleach solution is the best course of action after a blood sample spill.
