Why is it important to know the LEL of a substance like Benzene?

Knowing the Lower Explosive Limit (LEL) of a substance like Benzene is crucial primarily for assessing its flammability risk. The LEL is the lowest concentration of a vapor in air that can ignite and cause an explosion if an ignition source is present. For safety and operational protocols, understanding the LEL allows workers and safety officials to implement necessary precautions in environments where Benzene is present. This helps in reducing the likelihood of fire hazards, ensuring safe handling and transportation of the substance, and maintaining compliance with safety regulations.

Understanding the LEL does not directly relate to determining the boiling point of Benzene, establishing its toxicity, or identifying its market value, as those considerations focus on different properties and implications of the chemical.
