Quick Answer
A handheld smoke flare typically lasts between 30 seconds to 1 minute, depending on the specific type and manufacturer. These flares produce a dense, white smoke that can be seen from a distance, making them effective for signaling. However, they burn out relatively quickly, requiring multiple flares to maintain visibility for an extended period.
Types of Signal Flares
There are two main types of signal flares: pyrotechnic and smoke-producing. Pyrotechnic flares emit a bright light, while smoke-producing flares emit a dense, white smoke. Handheld smoke flares are a type of pyrotechnic flare that produce a smoke output instead of light. They are commonly used for signaling and can be seen from a distance during the day or night.
Choosing the Right Handheld Smoke Flare
When selecting a handheld smoke flare, consider the duration of use and the environment in which it will be deployed. Handheld smoke flares usually last between 30 seconds to 1 minute and come in different sizes, ranging from 25mm to 50mm in diameter. The size of the flare affects its burn time and smoke output, with larger flares typically lasting longer. When choosing a handheld smoke flare, consider the following factors: burn time, smoke output, size, and wind resistance.
Safety Precautions
When handling handheld smoke flares, exercise caution and follow safety guidelines. Always read the manufacturer’s instructions and follow local regulations. Wear protective gear, including gloves and safety glasses, when handling flares. Store flares in a cool, dry place, away from children and pets. Never touch the flare’s surface, as the chemicals can cause skin irritation and burns.
