Where is the best place to store flammable solvents?

1. Vented safety cabinet

2. Room equipped with running water

3. Fume hood

4. Sealed dark glass bottles

The correct answer is: Vented safety cabinet

Storing flammable solvents in a vented safety cabinet is optimal because these cabinets are designed specifically to reduce the risk of fire and chemical exposure. They are constructed to contain spills and vapors while providing proper ventilation, which minimizes the accumulation of flammable vapors that could lead to an explosive environment. The design often includes materials that are resistant to fire and are compliant with safety regulations, ensuring that the solvents are securely stored away from potential ignition sources. In contrast, while a fume hood can provide some protection and ventilation for hazardous substances, it is typically used for processes that require immediate removal of vapors or fumes during active handling, rather than for long-term storage. Storing flammable liquids in a room equipped with running water might be beneficial for certain emergencies, but it does not provide the specific containment and safety features necessary for flammable solvent storage. Although sealed dark glass bottles are useful for protecting contents from light and contamination, they do not inherently offer the fire safety and vapor containment needed for flammable solvents.
