Which of the following is a requirement for a flammable and combustible liquids storage area?

The requirement for a flammable and combustible liquids storage area to have visible warning signs is crucial for safety and hazard communication. These signs serve to alert individuals about the potential dangers associated with the storage of these types of liquids, helping to prevent accidents and ensuring that people are aware of the risks. Visible warning signs provide critical information that can guide behavior—such as not smoking in the vicinity or understanding that certain protective equipment may be required when working near the storage area.

This requirement reflects established safety practices and regulatory standards that focus on minimizing risks associated with hazardous materials. Effective signage can help prevent both accidental ignition of flammable vapors and unauthorized access to hazardous areas, thus enhancing overall safety for workers and the surrounding environment.
