Which ratio is used to determine the source of fuel for an explosion?

The Trickett's ratio is employed in the analysis of an explosion's fuel source because it compares the proportions of different gases present in the explosive mixture. Specifically, this ratio examines the levels of methane and carbon dioxide in the atmosphere where the explosion occurred, helping investigators identify whether an explosion was likely caused by methane gas or other fuel sources.

In investigations of gas-related incidents, understanding the composition of the gases involved can reveal critical information about the conditions leading up to the explosion. The Trickett's ratio is particularly significant because it provides insights into how combustible gases interacted prior to the event, assisting in reconstructing the scenario that led to the explosion. This focused approach is essential for safety assessments and formulating procedures to prevent such incidents in the future.
