How to Sign "Danger"
To sign danger, start by forming both hands into 'A' shapes, which are fists with the thumbs resting against the side. Hold your non-dominant hand in front of your chest with the palm facing down. Take your dominant hand, point the thumb upward, and slide the back of the thumb upward along the back of your non-dominant hand. Repeat this upward brushing motion twice. Remember to use a serious facial expression to convey the urgency of the warning.
