Current causation knowledge indicates the premise to be invalid.
Examples include electrocution hazards or areas within which there is a risk of exposure to toxic chemicals. In some regions, the specific color combination indicates the type of threat. For example, yellow-black tape may be used to signal the presence of a physical hazard (e.g., a hole), while magenta-yellow can denote a radiation hazard.
