Use of Security pictograms

Security pictograms are always shown within either a red, orange or green outline with a cross, exclamation mark or tick in a smaller circle attached to it. This denotes prohibited, caution/advisory or correct/safe status.

To correctly place the pictogram into the relevant outline, reduce the pictogram to 85% of the size (height) of the outline template, and position it exactly in the centre of the outline circle. The outline and small circle goes in front of the pictogram, so the top right section of the pictogram is partially obscured. Group the two elements together so that if resized the proportions stay correct.

There are no reversed versions of Security pictograms, as the red, orange or green outlines allow them to be used on either black or white backgrounds.

Only the 9 Forbidden Items are shown with the red strike-through, as supplied.
