1.  Safety signs should not be located in a place containing a number of other signs or objects of similar size and colour.
2.  Safety signs should not be located in areas where colour contrast is poor.
3.  Add supplementary text to safety signs to increase their length and further improve comprehensibility and legibility.
4.  Train all staff, occupiers and visitors to understand the distinctive color and geometric shape of safety signs as well as the    detail of any graphical symbol signs used.  Continue to reinforce this training and awareness.
5.  For fire exit safety signs, it is preferable to use additional reinforcing directional signs rather than rely on one larger sign at a longer viewing distance.
