Mandatory (DO) Signs (MV)
Mandatory Signs are SABS Approved safety signs that indicates that a specific course of action is to be taken.
These symbolic safety signs display a white pictogram on a blue circular shaped sign, depicting the wear personal protective equipment..
The height, width or diameter of the pictogram on these signs occupy between 75 % and 90 % of the corresponding dimensions of the backing sheet, either Chromadek Steel or ABS Plastic.
SABS approved sizes for safety signs are 150x150mm, 190x190mm, 290x290mm, 440x440mm and 880x880mm. It is however uneconomical to print 150x150mm so the industry by large has adopted printing 190x190mm and up.
