How Many Fires Should You Build for SOS?

April 5, 2026

Quick Answer

Build 3 fires in a triangular formation, spaced about 100 to 200 feet apart, to create a clear and visible signal.

Creating a Signal Smoke Fire

When building a signal smoke fire for SOS, your goal is to create a visible signal that can be seen from a distance. This is typically achieved by creating a large column of smoke, but the fire itself also plays a crucial role. The standard technique is to build 3 fires in a triangular formation, spaced about 100 to 200 feet apart. This allows you to create a clear and visible signal that can be seen from a distance.

Fire Size and Shape

Each fire should be about 3 to 5 feet in diameter, with a moderate to large size. You want the fire to be large enough to produce a good amount of smoke, but not so large that it’s difficult to control. The shape of the fire should be a simple, open circle or oval, with no branches or obstructions.

Timing and Repeating the Signal

To maximize the effectiveness of your signal, it’s essential to time your fires correctly. The standard signal pattern is 3 short flashes of smoke, followed by a brief pause, then 3 more short flashes. Repeat this pattern for a total of 3 sets, with a 30-second pause between each set. This will help you signal your location to potential rescuers and increase your chances of being seen.
