WARNING: Fuel fire/explosion hazard
Gasoline is highly flammable and explosive. Burner fuels are
combustible at warm temperatures. Heat, sparks, and flames can
ignite fuel vapors, which can become widespread during fueling. A
flash fire and/or explosion could result and cause serious injury or
death. Always use extreme care when handling fuels. Carefully
follow all instructions to avoid the following conditions which could
result in fuel ignition:
 gas vapor collection inside enclosures

static electric sparks

sparks from electric wiring, batteries, or running engines

sources of heat (such as a hot engine, burner or exhaust)

open flames, including pilot lights
