Which of the following is true regarding Benzene's LEL?

The correct answer highlights the importance of understanding the Lower Explosive Limit (LEL) of benzene in safety protocols. The LEL represents the lowest concentration of benzene in air that can ignite if an ignition source is present. This makes it a critical factor in ensuring workplace safety, particularly in environments where benzene or similar substances are handled or stored.

Recognizing the LEL allows workers and safety supervisors to assess the flammable risks associated with benzene. By monitoring levels of benzene in the environment, proactive measures can be taken to mitigate fire and explosion risks, ensuring that concentrations remain below the LEL during operations. This focus on safety is integral to developing effective safety protocols and training systems, highlighting how benzene's LEL plays a vital role in industrial safety practices.

In contrast, the other options downplay the safety aspects of benzene. For example, stating that benzene has a low flammability risk overlooks its potential hazards, while suggesting it indicates a safe working condition fails to account for the conditions when its concentration nears the LEL. Lastly, deeming it irrelevant for indoor storage ignores the fact that confined spaces can significantly amplify the risks associated with flammable vapors. Understanding LEL is crucial for any handling
