NZS/AS 1319:1994 advocates simplicity and clarity in safety signage. To be effective, they should be easy to read and interpret at a glance.

The Standard is about the use of legible text and appropriate, simple symbols.

By simplifying the message, it reduces the risk of misinterpretation, which increases the chances of the sign’s warning or instruction being followed.

Enhancing the signs visibility through placement and colour

Placement and visibility will play a crucial role in the efficiency of safety signs.

The standard states that signs must be positioned near the hazard they are warning about, which ensures that the safety message is relevant. Also it advocates the use of contrasting colours for the background and lettering. This attention to the colour scheme will increase visibility and readability from a reasonable distance, which ensures the message is accessible.
