Which solution should the paramedic use to clean and disinfect equipment exposed to bodily substances?

• A. Soap and water
• B. Antibacterial soap diluted in water
• C. Hydrogen peroxide diluted in water
• D. Bleach diluted 1:10 in water

Answer: (D)

When equipment has been exposed to bodily substances, you want a method that reliably reduces a wide range of pathogens after you’ve removed the obvious contamination. A diluted bleach solution at 1:10 is a proven, broad-spectrum disinfectant that inactivates many viruses, bacteria, and fungi when it remains on the surface for the recommended contact time. This level of disinfection is especially important for EMS gear and surfaces that can come into contact with patients. Using bleach at this dilution balances effectiveness with practicality: it’s inexpensive, readily available, and effective on most nonporous surfaces. Remember to follow the proper contact time and consider material compatibility, since bleach can be caustic and may corrode some metals or delicate equipment. After disinfection, rinse if necessary per equipment guidelines and allow to air-dry. Other choices either address cleaning rather than disinfection (soap and water), rely on products primarily meant for skin protection rather than surface disinfection (antibacterial soap diluted in water), or may require longer contact times or have limitations in stability and material compatibility (hydrogen peroxide diluted in water).
