Hazard Warning Signs

Hazard signs designed to warn of hazardous or dangerous materials, locations or objects, including electric currents, poisons, and radioactivity. Hazard symbols may appear with different colours, backgrounds, borders and supplemental information in order to specify the type of hazard and the level of threat (for example, toxicity classes). Warning symbols are used in many places in lieu of, or in addition to written warnings as they are instantly recognisable and more commonly understood.
