Flares are bright, burning devices used to signal for help or to indicate a specific location. They produce a strong light and can be seen from a distance, making them useful in emergencies, such as maritime distress or during outdoor activities. Flares come in various types, including handheld and aerial, each designed for different situations. In addition to their signaling purpose, flares are also used in military operations to illuminate areas or mark targets. They are typically made of a combustible material that burns brightly for a short period. Safety precautions are essential when using flares to prevent accidental fires or injuries.
