When fighting a horizontal flammable-gas cylinder fire, you should operate from:

When fighting a horizontal flammable-gas cylinder fire, operating from the side is the most effective and safest strategy. This approach minimizes the risk of exposure to direct flames and allows responders to be positioned at a safe distance from the potential hazards while still maintaining an effective line of sight and access to the fire.

Fighting a fire directly from the end of the cylinder can expose responders to high-intensity heat and potentially increase the risk of an explosion if the cylinder were to rupture or project flame forward. Approaching from a 45-degree angle can provide some safety, but it does not allow for the same level of control or safety margin as positioning directly alongside the cylinder while still maintaining a safe distance. Operating from the most accessible location may seem practical, but it’s crucial to consider safety first; access points can vary significantly in terms of hazards and effectiveness in controlling the fire.

Utilizing the side position allows responders to effectively use extinguishing agents on the flames or on associated combustible materials while being shielded from the fire’s most intense heat. It also ensures that the gas outlet and pressure relief devices are not directly exposed to flames, reducing the risk of catastrophic failure.
