Module 1. Properties and Characteristics of Natural Gas

Comparison with propane

Unlike natural gas, which naturally tends to rise, propane tends to sink and may accumulate in trenches, drains and other low-lying areas. Keep this behavior in mind if you are called to an incident that involves a propane pipeline.

Be alert for propane in leak or fire incidents involving gas grills, as propane is the fuel most commonly used in these appliances.
