When using an extinguisher on a small propane fire, from which direction should you approach?

Approaching a small propane fire from an upward direction is based on the behavior of flames and the nature of propane gas. Propane, being a gas, tends to rise when ignited, especially in the presence of heat. By approaching from below, you are positioning yourself where the flames are the hottest and where the gas is escaping. This position allows you to effectively direct the extinguishing agent towards the base of the fire, where fuel meets flame, which is critical for extinguishing the flames effectively.

Utilizing an extinguishing agent from below helps to smother the flames and cut off the oxygen supply without putting the firefighter directly into the flames or gas that may be escaping. It reduces the risk of injury and increases the effectiveness of the extinguishing process.

Other approaches, such as from below or the side, may not provide adequate access to the base of the fire, making it difficult to extinguish it effectively. Approaching directly above could expose a person to the immediate danger of flames and hot gases, which can be harmful and unsafe. Therefore, an upward approach is most effective and safe for handling small propane fires.
