~ <br />Lque:fied petroleum gases (LPGs) include propane, butane, and <br />other LPG mixtures that are popular fuel sources for heating, <br />cooking, illumination, and industrial processes. LPG has an ignition <br />temperature in air of 900 °F to 1,020 °F (482 °C to 549 °C) and <br />a maximum flame temperature in air from 3, 5 9 5 °F to 3, 61 S °F <br />( 1, 9 7 9 °C to 1, 9 91 °C). These hazards require that storage facilities <br />be arranged to minimize catastrophic events. <br />National Fire.
