Common Mistakes to Avoid

1. Wrong Sign Type for Hazard

Using warning signs where prohibition signs are required creates confusion and legal non-compliance.

2. Inadequate Size

Signs too small for viewing distance fail to communicate effectively and don't meet regulations.

3. Poor Positioning

Signs obscured by doors, equipment, or at wrong heights reduce effectiveness significantly.

4. Mixed Standards

Combining old and new symbol systems creates confusion—update all signs together where possible.

5. Neglecting Maintenance

Faded or damaged signs give impression of poor safety culture and may not protect legally.

Training Requirements

Ensure all employees understand:

What signs mean - Each symbol and colour
Required actions - What they must do
Why signs matter - Legal and safety reasons
Reporting damage - Who to inform immediately

Cost-Benefit Analysis
