Are There Different Patterns for Different SOS Situations?

Different Patterns for Nighttime Emergencies

For nighttime emergencies, a smoke signal pattern is most effective. This involves creating smoke during a 3-minute interval, followed by a 4-minute interval without smoke, and then repeating this pattern for 30 minutes. The smoke should be visible from a distance, ideally at an altitude of 10-15 feet, using dry, green leaves, or other flammable materials.

Daytime Emergency Patterns

During the day, a smoke signal may not be as effective due to the sun’s glare. In such cases, a fire signal is used, where three large fires are lit in a row, spaced 30 seconds apart, and repeated for 30 minutes. The fires should be large enough to be visible from a distance of 10 miles, and ideally should be lit on a hilltop or a high spot.

Fire-Based Signals for Specific Situations

In situations where a fire is already present, such as in a wildfire scenario, a fire signal can be used. For example, in a wildfire, three fires can be lit in a row, spaced 30 seconds apart, to signal for help. However, in a survival situation where a fire is not present, a smoke signal or a fire signal using dry wood or other flammable materials should be used.
