What does the skull and crossbones symbal stand for when it is on a chemical?
Direct from Wiki: “Toxic sign Main article: Skull and crossbones The skull-and-crossbones symbol, consisting of a human skull and two bones crossed together under the skull, is today generally used as a warning of danger, particularly in regard to poisonous substances. The symbol, or some variation thereof, was also featured on the Jolly Roger, the traditional flag of European and American pirates. It is also used by Skull and Bones, a secret society at Yale University, and is part of the WHMIS home symbols placed on containers to confirm that the substance inside is dangerous in a way. In the USA, due to concerns that the skull and bones symbol’s association with pirates encourages children to play with toxic materials, the Mr. Yuk symbol is also used to denote poison.
