What is the proper procedure when using a hand held visual distress signal flares?

When using handheld visual distress signal flares, first ensure you are in a safe location, away from flammable materials. Hold the flare away from your body and point it towards the horizon to avoid injury from the flame. Ignite the flare according to the manufacturer's instructions, and wave it back and forth to attract attention. Always use flares during daylight for optimal visibility, and ensure they are stored properly to maintain functionality.
