Why must tanks with flammable liquids be stored outdoors?

Storing tanks with flammable liquids outdoors is crucial primarily to reduce the risk of fire and explosion. Flammable liquids can easily ignite when exposed to certain conditions, such as high temperatures or sources of ignition. By keeping these tanks outdoors, the potential hazards associated with a confined space, where flammable vapors could accumulate and create an explosive environment, can be significantly minimized.

Outdoor storage allows for better dispersion of vapors, reducing the likelihood of a dangerous buildup that could lead to combustion. Additionally, in the event of a leak or spill, the outdoor environment provides an immediate avenue for the liquid to evaporate and dissipate, rather than posing a risk of pooling or creating hazardous conditions in an enclosed area. This practice aligns with safety regulations designed to protect individuals and property from the inherent dangers of flammable materials.

The other options, while they touch on relevant safety measures, do not capture the primary reason for outdoor storage as effectively as the chosen answer. Proper ventilation is certainly an important factor, but it is more about addressing existing hazards rather than the major justification for outdoor storage. Preventing exposure to sunlight is less relevant in this context because while UV rays can impact certain materials, the focus should be on avoiding combustibility. Simplifying transportation is a
