Which practice helps minimize risk when storing chemicals?

• A. To minimize chemical reactions and fires by segregating incompatible substances
• B. To make storage easier
• C. To comply with air quality
• D. To reduce labeling requirements

Answer: (A)

The main idea here is preventing dangerous reactions by keeping incompatible chemicals apart. When certain substances meet, they can react unexpectedly, causing fires, explosions, or the release of toxic gases. By separating chemicals that shouldn’t touch each other—such as acids from bases, oxidizers from fuels, and water‑reactive substances from moisture—you dramatically lower the chance of a hazardous interaction during storage. Additional safeguards like using dedicated shelves or cabinets, labeling clearly, and using secondary containment help ensure that spills or leaks don’t bring incompatible items into contact, further reducing risk.

Choosing to store chemicals for ease of access or to meet air quality considerations doesn’t directly address the risk of dangerous reactions in storage. And reducing labeling requirements removes critical hazard information, which can lead to improper handling and higher risk.
