Quick Answer
When transporting a heatstroke victim, use emergency signaling methods such as sounding a horn or alarm, flashing headlights, and displaying a brightly colored cloth or flag to alert others to the emergency. This can be done while in a vehicle or on foot, and should continue until medical help is reached. Signal frequently to ensure safety.
Visual Signals
When transporting a heatstroke victim, visual signals are crucial to alert others to the emergency. Display a brightly colored cloth or flag, such as a red or orange bandana, from the vehicle or a fixed point, like the top of a flagpole. The American Red Cross recommends using a minimum of 12 square inches of brightly colored fabric. Consider using a reflective triangle or road flares to increase visibility, especially at night.
Auditory Signals
Sounding a horn or alarm is another effective way to signal for help. Use a loud, steady horn or an air horn to alert others to the emergency. The National Highway Traffic Safety Administration recommends using a horn with a frequency of 1,600 to 1,700 Hertz for maximum visibility. When in a vehicle, also use the hazard lights to alert others to the emergency.
Additional Tips
When signaling, be sure to signal frequently and consistently to ensure safety. This may involve repeating the signal every 10-15 seconds or using a pattern of signals to convey the emergency. Consider using a signaling device, such as a Personal Locator Beacon (PLB), if you are in a remote area with no cell service.
