What is the explosive range of LPG?

The explosive range of liquefied petroleum gas (LPG) typically falls between 1.8% and 9.5% by volume in air. Below 1.8%, the mixture is too lean to ignite, and above 9.5%, it is too rich for combustion. This range is crucial for safety measures in environments where LPG is used or stored. Proper ventilation and monitoring are essential to prevent dangerous accumulations.
