Separate refrigerators should be used for the storage of _____ and ______ because the fumes of some chemicals may be harmful to ______.

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

Answer: (A)

Fumes from certain chemical reagents can harm living microbiological samples, so they must be kept apart to protect the viability of the organisms and the accuracy of test results. Microbiological samples are delicate biological materials, and exposure to vapors from solvents, acids, or other reagents can inhibit growth or kill the organisms, leading to unreliable data. Keeping these two stored separately also reduces cross-contamination and enhances safety for personnel handling both substances. The other options introduce items like food or people that aren’t the biological samples being protected by this practice, so they don’t address the same risk to the organisms.
