What are some common safety sign symbols?

Safety symbols available from Osha.gov include the skull and crossbones symbol, flame symbol, health hazard symbol and corrosion symbol, according to the Occupational Safety & Health Administration. The symbols contain black and white representations of various dangers. For example, the flame symbol pictures a simple outline of a fire.

The corrosion symbol pictures two test tubes, one emptying over a hand with lines emerging from the hand to indicate damage and the other test tube emptying over a black line that has the same lines showing damage emerging from it, according to OSHA. The skull and crossbones symbol is also a black and white pictogram and shows a skull with two bones crossed underneath it in a shape that resembles an "X."
