Baldwin began to work on ideas for the new symbol. It often appears on hazardous equipment or in instruction manuals to draw attention to a precaution, when a more-specific warning symbol is not available. Biogefährliche Substanzen sind nach Gefahrgutrecht für den Transport nach UN-Nummern klassifiziert: In Unicode findet sich das entsprechende Symbol an der Stelle U+2623 (☣). It is called the Biohazard symbol, a name that says it all! Hazard symbols may appear with different colors, backgrounds, borders, and supplemental information in order to specify the type of hazard and the level of threat (for example, toxicity classes). There are several systems of labels, depending on the purpose, such as on the container for end-use, or on a vehicle during transportation.
