- Photoluminescent where re
| Sign Type | Typical Colour Scheme | Main Function |
|---|---|---|
| Warning | Yellow and black | Alert to hazards such as wet floors |
| Prohibition | Red and white | Restrict entry or actions |
| Mandatory Action | Blue and white | Indicate required safety measures |
| Emergency Information | Green and white | Direct to exits and first aid |
Pro tip: Conduct regular visual inspections of safety signage to ensure signs remain clean, unobstructed, and positioned at optimal viewing heights for maximum visibility and comprehension.
The following table compares standard and bespoke safety sign solutions for retail:
| Solution Type | Customisation Level | Typical Benefit | Potential Drawback |
|---|---|---|---|

Pro tip: Consider implementing a hybrid approach that combines standardised safety iconography with custom design elements to maximise comprehension and site-specific relevance.
Design Principles for Effective Safety Signs
Visibility and Legibility
Distance Calculations: Sign size must relate to viewing distance:
Formula: Sign height (mm) = Viewing distance (m) × 25
Examples:
- 5m viewing distance = 125mm minimum sign height
- 10m viewing distance = 250mm minimum
- 20m viewing distance = 500mm minimum
Contrast Requirements:
- High luminance contrast (minimum 70%)
- Color contrast (complementary combinations)
- Non-glare surfaces
- Appropriate lighting (natural or artificial)
Pictogram Clarity
Symbol Selection:
- Use standardized ISO 7010 pictograms
- Avoid custom or ambiguous symbols
- Simple, recognizable imagery
- No text-only signs (language barriers)
- Supplementary text permitted (clarity enhancement)
Photoluminescent Properties
Glow-in-the-Dark Signs: Essential for emergency/exit signage:
Requirements:
