2026 Blue Bird Vision Propane

Propane is a very safe alternative fuel – both for the environment and the children that ride in our propane-powered school buses.

Propane is 270 times more compact as a liquid than as a gas, making it safe and economical to store and transport. Wearing gloves and goggles is recommended when refueling (which is also recommended for CNG, diesel and gasoline fueling).

Because it is released from a pressured container as a vapor, propane autogas can’t be ingested like gasoline or alcohol fuels. To put it simply, igniting propane gas in the air calls for very specific things to occur: 1)The mixture of propane/air must contain 2.2 percent to 9.6 percent propane vapor. Any more, or any less than that, and the propane will not ignite, 2) The source of ignition must reach 940 degrees Fahrenheit. In contrast, gasoline will ignite at only 430 to 500 degrees Fahrenheit.

Propane autogas fuel tanks are 20 times more puncture-resistant than typical diesel or gasoline tanks. They are made from carbon steel, include vapor-tight enclosures around all lines and fittings, and are manufactured with an Overfilling Prevention Device (OPD) that ensures the fuel volume will be able to adjust with temperature variations. There is also a pressure release device in every tank should the pressure rise beyond safe levels.

Even in 20g frontal impact, or 8g side or rear impact (which is twice the requirement specified in NFPA58), the propane tank will remain securely in place. It is also mounted between Blue Bird’s durable frame rails, which creates additional safety.
