Which practice is recommended for safe chemical storage?

• A. Store according to their properties and classification
• B. Store chemicals alphabetically for easy access
• C. Keep all chemicals in direct sunlight to maintain stability
• D. Store flammable liquids with oxidizers in the same cabinet

Answer: (A)

Storing according to their properties and classification means grouping chemicals by hazard type, reactivity, and storage needs so that incompatible substances are kept apart and each item is kept under conditions appropriate for its stability. This approach reduces the risk of dangerous reactions, spills, and exposure, and helps ensure proper ventilation, temperature control, and containment. For example, acids are kept separate from bases, oxidizers away from organics and fuels, and flammable liquids are placed in dedicated flammable-storage cabinets, with light- or heat-sensitive items protected from sunlight or heat. Storing alphabetically ignores compatibility, while direct sunlight can degrade many chemicals and mixing flammable liquids with oxidizers poses a serious fire or explosion hazard.
