Using proper ventilation while handling flammable liquids is crucial primarily to prevent hazardous vapor accumulation. Flammable liquids can emit vapors that are not only harmful to health but can also create explosive atmospheres when they accumulate in confined spaces. Ensuring adequate ventilation allows these vapors to disperse effectively into the atmosphere, reducing the risk of fire and explosion.

While improving air quality can be a benefit of proper ventilation, the primary concern when working with flammable liquids is the safety associated with the management of vapors. Preventing heat generation is relevant in specific contexts, such as when discussing the storage of flammable materials, but it is not the main goal of ventilation itself. Aesthetic appeal is not a safety concern in this context and does not support the fundamental safety requirements when working with hazardous materials.
