Which term refers to performing tasks under sterile conditions to prevent contamination?

• A. Aseptic Technique
• B. PASS
• C. Fire Triangle
• D. Agar

Answer: (A)

Aseptic technique is the practice of performing tasks under sterile conditions to prevent contamination. This means maintaining a sterile field, sterilizing tools and surfaces, using sterile gloves and protective gear, and minimizing any introduction of microbes during procedures such as handling cultures or preparing sterile products. The goal is to keep the work environment free from contaminants that could alter results or cause infections.

The other terms describe different ideas: one is a safety procedure for using a fire extinguisher, another outlines the elements needed for combustion, and the last is a gel medium used to grow microbes. None of these focus on maintaining sterility during tasks, so they don’t fit the concept described.
