What is the explosive range of Hydrogen?

Hydrogen has an explosive range measured by the concentration of the gas in the air, which is critical for understanding its flammability and safety precautions in various environments. The correct explosive range of hydrogen is between 4.1% to 74% by volume. This range indicates that hydrogen can ignite and explode when it is present in these concentrations in the air, making it particularly hazardous in confined spaces or environments where hydrogen gas might accumulate.

Understanding this explosive range is essential for safety practices in industries where hydrogen is used or produced, as it informs procedures for handling, storage, and emergency management when dealing with this flammable gas. It is also important for designing systems that prevent any situation where the concentration of hydrogen could reach explosive levels.
