Safety Signage in Portugal: A Guide for Commercial, Workplace, and Public Spaces

Safety signage is essential in commercial premises, workplaces, and public spaces in Portugal. It serves to inform, warn, and guide people about risks, safety standards, and emergency procedures, ensuring protection for employees, customers, and visitors.

Why is safety signage important?

Safety signage helps to:

• Prevent accidents: warning about slippery floors, risk areas, dangerous chemicals, or machinery.

• Guide evacuations: indicating emergency exits, escape routes, and assembly points in case of an incident.

• Comply with Portuguese legislation: according to the Labour Code, Decree-Law no. 220/2008 and international standards such as NP EN ISO 7010, all spaces with specific risks must have appropriate signage.

• Reduce legal liability: clear signage reduces the risk of accidents and protects companies or institutions from legal issues.

Types of safety signage

Safety signage in Portugal follows international standards and can be classified into five main types:

1. Warning signs (danger)

   • Indicate specific risks.

   • Predominant colour: yellow or red.

   • Examples: "Danger: High Voltage", "Caution: Slippery Floor".

2. Prohibition signs

   • Indicate prohibited actions.

   • Predominant colour: red.

   • Examples: "No Smoking", "Restricted Entry".

3. Mandatory signs

   • Show mandatory behaviours.

   • Predominant colour: blue.

   • Examples: "Mandatory PPE use", "Wear a hard hat".

4. Emergency signs

   • Indicate escape routes, emergency exits, fire extinguishers, and first aid points.

   • Predominant colour: green.

5. Informative signs

   • Provide general information or guidance.

   • Examples: location of restrooms, service counters, or information points.

Application of signage in different environments

• Commercial premises: indicating exits, stairs, wet areas, payment counters, and circulation zones.

• Workplaces: PPE signage, machinery, risk areas, chemical products, and evacuation routes.

• Public spaces: guiding people flow, evacuation routes, meeting points, and accident prevention in high-traffic areas.

How to choose the correct safety signage

To ensure efficiency, signage must be:

• Visible and legible, even from a distance.

• Standardised, following Portuguese and ISO standards.

• Updated, reflecting changes in risks or the layout of the space.

• Durable and resistant, suitable for environmental conditions (indoor or outdoor).

Conclusion

Safety signage in Portugal is an investment in safety, organisation, and legal compliance. Commercial, work, or public environments that adopt clear and standardised signage reduce risks, protect people, and increase the confidence of customers and employees.
