What type of hazard is associated with areas where flammable liquids are stored?

The classification of flammable liquid storage as a heavy hazard is based on the significant risks they pose in the event of a fire. Heavy hazards are characterized by the presence of materials that can ignite easily and lead to a substantial fire or explosion. Flammable liquids, such as gasoline, solvents, and other volatile chemicals, can easily catch fire, especially when in proximity to heat sources or sparks.

When flammable liquids ignite, they can produce intense heat and flames, potentially spreading rapidly and affecting surrounding areas. This type of environment requires stringent safety measures and fire protection systems to mitigate the risks associated with the storage and handling of such materials. Therefore, identifying it as a heavy hazard is crucial for proper safety planning and prevention strategies in industrial or commercial settings.
