Identify the materials that should be isolated from flammable liquids during storage.

• A. Water, air, and moisture.
• B. Food products.
• C. Electrical equipment.
• D. Oxidizers, acids, and heat sources.

Answer: (D)

Flammable liquids must be kept away from materials that can react with them or provide an ignition path. The materials that should be isolated are oxidizers, acids, and heat sources. Oxidizers can supply oxygen, making even small spills burn intensely. Acids can react with many organic solvents, releasing heat or gases and potentially causing violent reactions. Heat sources—such as open flames, hot surfaces, or sparking equipment—can ignite flammable vapors at any point. The other options don’t represent the primary incompatibilities for storage. Water, air, and moisture aren’t the typical classes that require separation from flammable liquids; water can help extinguish fires, and moisture effects depend on specific substances. Food products aren’t related to chemical incompatibility in storage, and while electrical equipment can pose a spark risk, it’s not a material class that must be isolated from flammable liquids in the sense of chemical incompatibility.
