The Australian Safety Standard AS 1319 governs how safety signs are designed, manufactured, and used in occupational environments. Did you know that non-compliant signage can invalidate safety procedures and lead to significant WHS fines?
Whether you are setting up a new warehouse or auditing an existing construction site, purchasing signs that don't meet the correct colour, size, or symbol requirements is a major safety risk. This comprehensive guide ensures your signage strategy is 100% compliant and effective.
1. The Five Main Classifications of AS 1319
AS 1319 classifies signs into five distinct categories, each identifiable by its unique colour and shape. Understanding these differences is the foundation of compliant signage.
Mandatory Signs (Blue Circle)
- Purpose: Identifies actions that MUST be carried out.
- Design: Blue background, white graphical symbol/icon.
- Examples: 'Eye Protection Must Be Worn', 'Safety Harness Required Beyond This Point'.

Prohibition Signs (Red Circle)
- Purpose: Identifies actions that MUST NOT be carried out.
- Design: White background, red circle and diagonal slash over a black symbol.
- Examples: 'No Smoking', 'Do Not Enter', 'No Pedestrian Access'.

Warning Signs (Yellow Triangle)
- Purpose: Alerts staff to hazards or hazardous conditions that are NOT life-threatening.
- Design: Yellow background, black border, and black symbol/text.
- Examples: 'Caution Wet Floor', 'Hazardous Voltage', 'Forklift Traffic'.

Emergency Information Signs (Green Square/Rectangle)

- Design: Green background, white symbol/text.
- Examples: 'First Aid Post', 'Emergency Exit', 'Eye Wash Station'.

2. Critical Compliance Requirements Beyond Colour
Simply having the right colour isn't enough. AS 1319 also dictates key physical and visibility standards:
A. Size, Viewing Distance, and Visibility
The size of the sign must correspond to the maximum distance from which it needs to be read. As a rule, signs viewed from a greater distance (e.g., across a large factory floor) must use larger text and symbols.
B. Durability and Materials
Signs used outdoors or in high-impact environments (like manufacturing or mining) must be constructed from materials that resist UV light, chemicals, and abrasion. We strongly recommend using high-quality polypropylene or metal for maximum longevity and compliance.
C. The Use of Symbols and Text
While symbols are critical, AS 1319 mandates that text is used to clarify the symbol’s meaning, especially for Warning and Prohibition signs, to avoid any ambiguity in the safety message.
3. Location, Illumination, and Placement
A compliant sign must be placed in a conspicuous position. This means:
- It must be at an appropriate height (usually eye-level).
- It cannot be obscured by equipment, doors, or other objects.
- It must be illuminated, especially in low-light areas like underground tunnels or darkened warehouses.
For exit routes or areas where power may fail, **Photoluminescent Signs** (which absorb light and glow in the dark) must be used to guide staff to safety.
