What is the maximum explosion limit for propane gas?

8.5%
9.5%
15%
20%

The correct answer is: 8.5%

The maximum explosion limit for propane gas is 9.5%. This figure represents the upper flammability limit, indicating the maximum concentration of propane in air that can still ignite and sustain a combustion reaction. Beyond this concentration, there is too much propane to support combustion. Understanding this limit is crucial for safety when working with propane. If the concentration exceeds this percentage, it can lead to incomplete combustion, which poses a serious risk for fires and explosions. Proper ventilation and monitoring of gas concentration are essential in environments where propane is used or stored. Recognizing the correct explosion limit helps gas fitters and technicians establish safe operating practices and ensures compliance with safety regulations, minimizing the risk of hazardous incidents.
