How should incompatible substances be stored?

• A. Mixed together on the same shelf
• B. On different shelves or placed in non-flammable storage cabinets
• C. In same stack as long as labeled separate
• D. In any location as long as clearly marked

Answer: (B)

Incompatible substances must be stored separately to prevent chemical reactions, fires, or release of hazardous gases. Keeping them on different shelves or in non-flammable storage cabinets physically separates them, reducing the chance of contact, spills, or vapors propagating to other containers. Merely labeling containers or placing them in the same stack does not prevent accidental mixing, especially in busy work areas where items can be misplaced or mishandled. Therefore, the safest practice is to store incompatible substances on different shelves or in dedicated non-flammable storage cabinets.
