Propane has an enviable safety record due to the stringent codes and regulations developed by the propane industry in conjunction with the National Fire Protection Association (NFPA). Every aspect of installation, storage, and tank filling has been considered to ensure worry-free operation. 

The strict safety codes mandated by the propane industry are further enhanced by propane's naturally safe features. For starters, propane has a narrow range of flammability, meaning the propane/air mix must contain from 2.2% to 9.6% propane vapor to ignite. Any less than that and the mixture is too lean to burn; any more than that and the mixture is too rich to burn.

Also, propane will not ignite when combined with air unless the source of ignition reaches at least 940F. In contrast, gasoline will ignite when the source of ignition reaches 430F to 500F.

In addition, because propane is released as a vapor from a pressured container, it cannot be ingested like gasoline or alcohol fuels. If liquid propane leaks, it vaporizes and dissipates into the air.
