Separate refrigerators should be used for the storage of which items because fumes of some chemicals may be harmful to the organisms?

• A. Chemical Solutions, Food, People
• B. Microbiological Samples, Reagents, The Organisms
• C. Food, Chemical Solutions, People
• D. Microbiological Samples, Acid Solutions, The Organisms

Answer: (B)

Chemical fumes can harm living cultures, so laboratories separate refrigerators to store items that could affect one another. Microbiological samples, reagents, and the organisms themselves need to be kept apart because volatile chemicals or vapors from reagents can diffuse into storage and alter viability, growth, or integrity of the samples. This separation minimizes cross-contamination and protects the samples and organisms, keeping experiments reliable and safe. Foods, people, or only acids with organisms don’t fit because they introduce contamination risks or expose living cultures to corrosive fumes, which is not appropriate for preserving biological material.
