What is an effective method to signal rescuers when trapped?

• A. Shout for help
• B. Wave hands vigorously
• C. Turn on a flashlight and point it at the ceiling
• D. Make loud noise continuously

Answer: (C)

Turning on a flashlight and pointing it at the ceiling is an effective method to signal rescuers when trapped because it utilizes visible light to attract attention in potentially low-visibility situations. Flashlights are particularly beneficial in dark environments where other sound-based signals may not carry as far or be as effective. The focused beam can easily be recognized by rescuers from a distance, making it a direct and clear signal that can convey the need for assistance. Additionally, using a flashlight can help conserve energy compared to shouting or making continuous noise, which may lead to exhaustion. This method is also strategic, as it can help direct the rescuers' attention to a specific area, increasing the likelihood of a quick response. The illumination serves as a beacon, illustrating both your presence and exact location, which is especially valuable in emergency situations where time is critical.
