Quick Answer
Yes, there are special considerations for using flares in snow, as they may not be as effective in dense whiteout conditions and can be difficult to see due to the reflective surface.
Snow Conditions and Visibility
When using flares in snowy environments, visibility is crucial. In dense snowstorms, the whiteout conditions can obscure the bright colors and light of flares, making them less effective for signaling. Additionally, snowflakes and ice can reflect light, potentially confusing the direction of the signal. To mitigate this issue, use multiple flares and vary their positions to create a more visible signal.
Choosing the Right Flare
When selecting a flare for use in snowy conditions, consider the color and duration of the signal. Orange or yellow flares are generally more visible in snow due to their color temperature. For longer-distance signaling, choose flares that burn for at least 2-3 minutes. Some flares, like the S-100, have a 2-minute burn time and are a good option for snowy conditions. Others, like the M-47, burn for 5 minutes but may be less effective in dense snow.
Additional Safety Precautions
When using flares in snow, be aware of the potential for fire hazards and follow proper safety protocols. Store flares in a cool, dry place, away from flammable materials. When igniting a flare, do so in a well-ventilated area, and never touch the flare to your skin or clothing. If you are signaling in a vehicle, ensure the vehicle is in park and the parking brake is engaged to prevent accidental movement.
