This image is a familiar one, and it is very effective. It uses several elements to warn the viewer of the danger of poison. First, it is triangular, which is often synonymous with "caution." Second, it is red, a color known in nature to warn of danger. Third, it has the ominous skull and crossbones, which is an indicator of death. Finally, it actually spells out the word poison, to further reiterate the danger.
