Radiation Signs

Radiation signs communicate a warning to workers and the public that there is a hazard that is not considered life threatening. To comply with AS 1319, a Warning Sign must have a black triangle on a yellow background. A radiation symbol sits inside the triangle with additional text below.

When the radiation hazard is considered to be life-threatening, a Danger Sign must be used. A Danger Sign has the word ‘DANGER’ in white letters on a red oval inside a black background.
