 Most military flamethrowers use liquid fuel, typically either gasoline or diesel, but commercial flamethrowers are generally gas torches using fuels such as propane; gases are safer in peacetime applications, because their flames dissipate faster and often are easier to extinguish when necessary.Apart from the military applications, flamethrowers have peacetime applications where there is a need for controlled burning, such as in sugarcane harvesting and other land-management tasks.Various forms are designed for an operator to carry, while others are mounted on vehicles.
