Enamel hazard signs were a type of sign commonly used in Eastern Bloc countries during the Cold War to indicate the presence of potential hazards such as radiation or chemical contamination. These signs were made of porcelain enamel on steel or cast iron, and were designed to be durable and long-lasting, even in harsh outdoor environments.

Bold, simple graphics and a limited bright color palette
These signs typically featured bold, simple graphics and a limited color palette, usually including red, yellow, black and white, as they needed to be easily recognizable and easy to understand by people who may not be fluent in the local language. The pictograms used on these signs were standardized, and often depict a person in danger or the source of the hazard such as radioactive or chemical symbols.

Collecting enamel signs?
After the fall of communism, many of these signs were taken down or replaced with new, more modern signs. However, some of these signs can still be found in Eastern European countries, particularly in older industrial areas, abandoned buildings or in rural areas. Because of the rarity and historical value, some of these signs have become collectors items – and, of course, we've got some for you!
