Quizplus · Accepted Answer

When holding up one's thumb in front of the eye, the thumb should be at arm's length in order to blur the background. This is known as the "thumb technique" and is often used to determine a safe distance from a hazardous scene. If the Paramedic cannot see the scene with his thumb held up at arm's length, he is likely far enough away from the scene to be safe.
