How should flammable liquids be stored in commercial settings?

The correct choice emphasizes the importance of safety protocols when storing flammable liquids in commercial environments. Flammable liquids must be stored in safety cabinets that are specifically designed to contain spills and minimize the risk of fire. These cabinets are typically constructed from materials that can withstand high temperatures and are equipped to vent vapors safely.

Proper labeling is also crucial, as it ensures that anyone who may come into contact with these chemicals understands the hazards associated with them. This practice contributes to creating a safer work environment and complies with regulatory standards set forth by organizations like OSHA and NFPA.

Storing flammable liquids in open containers or unmarked barrels increases the risk of accidental ignition, while keeping them underneath sinks poses a significant safety hazard due to the potential for spills and chemical reactions. Thus, using safety cabinets represents best practice for minimizing risks associated with flammable liquids in commercial settings.
