Quick Answer
A flag signal conveying urgency should include a clear and concise message, such as the number of people in distress and the direction of their location, using internationally recognized colors and shapes.
Essential Flag Content
When signaling for rescue, include crucial details such as the number of people in distress, their location, and any hazards or obstacles. Use a combination of colors and shapes to convey this information. For example, a yellow flag with a black square and a number of black dots can indicate the number of people in distress, while a red flag with an arrow pointing to the left can show the direction of their location.
International Flag Conventions
Adhere to internationally recognized flag conventions to ensure that your signal is understood by rescuers. The International Standards Organization (ISO) and the International Maritime Organization (IMO) have established guidelines for flag signals, including those for emergency situations. Familiarize yourself with these guidelines and use flags that conform to international standards.
Signal Flag Placement and Size
Position your flag signal in a visible location, such as the top of a mast or a raised pole, to ensure it is seen by rescuers. Use flags that are at least 12 inches (30 cm) square and made of durable material to withstand wind and weather conditions. Consider using a flashlight or other light source to illuminate your flag signal at night or in low-visibility conditions.
