What is a disinfectant?

• A. A chemical substance that kills harmful bacteria or viruses
• B. A process to clean surfaces
• C. A device that sterilizes tools
• D. A soap used for handwashing

Answer: (A)

A disinfectant is a chemical applied to inanimate surfaces to kill or inactivate harmful microorganisms such as bacteria and viruses. It’s not just cleaning, which removes dirt, and it isn’t a device or a soap for handwashing. Disinfectants reduce the number of pathogens on surfaces to safe levels, though not all disinfectants kill spores unless they are specifically labeled as sporicidal. For best results, follow the product’s label for how to use it, including the required contact time, dilution, and which surfaces it’s safe to use on. Examples include bleach solutions and hydrogen peroxide-based products used on countertops, benches, and equipment.
