When cylinders are involved in fire, what is the recommended water application distance?

• A. From a safe distance.
• B. From close range.
• C. From above only.
• D. From a distance with direct attack at valve.

Answer: (A)

When a cylinder is exposed to fire, the priority is cooling the vessel to prevent heat buildup that could lead to rupture or explosion. Water applied from a safe distance lets you cool the cylinder’s surface effectively while keeping you out of the danger zone in case the cylinder vents or fails. Approaching closely or aiming directly at the valve increases risk, and attacking from above only may not adequately cool the entire cylinder. So the best approach is to keep a safe distance and use water to cool the cylinder from the outside until the heat is controlled.
