Quick Answer
Signal mirrors help during an evacuation scenario by reflecting sunlight towards potential rescuers, increasing their chances of seeing you and directing them to your location.
Using a Signal Mirror Effectively
When using a signal mirror, it’s essential to know the optimal time of day for reflection. Since the sun is usually highest in the sky between 11 am and 3 pm, this is the best time to use a signal mirror. Hold the mirror at an angle of about 35-40 degrees, which allows the sun’s rays to bounce directly off the mirror and create a bright flash.
Identifying the Target Audience
Identify your target audience by looking for any potential rescuers, such as aircraft, ships, or people on foot. Use a landmark or a recognizable feature as a reference point to help them locate you. Reflect the signal towards the target audience, taking into account the wind direction and any obstacles that might interfere with the reflection.
Practical Tips for Signal Mirror Use
Aim to generate a flash that’s visible for at least 1-2 seconds, as this is the minimum amount of time for rescuers to see and react to your signal. Practice using a signal mirror in different lighting conditions to get a feel for how it works. Remember to keep the mirror clean and dry to ensure optimal performance.
