Which gas has an explosive range up to 74%?

Hydrogen is known to have a broad explosive range, which can extend up to 74% in air, making it highly flammable and potentially dangerous in certain environments, such as mines. This wide explosive range indicates that hydrogen can ignite in a wide variety of concentrations, which is an important consideration in the context of mine safety.

In mining operations, the presence of hydrogen might be a result of various activities or chemical reactions, and understanding its explosive limits is crucial for implementing safety measures. Monitoring for hydrogen levels and properly ventilating areas where it may accumulate can help prevent dangerous explosions. Overall, the significant explosive range of hydrogen emphasizes the need for thorough training and preparedness for mine rescue teams to respond to potential incidents effectively.
