Warning symbols are mainly graphic images which identify a dangerous object or place. Warning symbols are used in many places in lieu of or addition to written warnings as they are quickly recognized (faster than reading a written warning) and more universally understood (the same symbol can be recognized as having the same meaning to speakers of different languages).
