In Portugal, regulated signage is essential to ensure safety, organization, and guidance in any public or private space. According to national and European legislation, safety signage follows standardized norms, with specific colors and shapes that allow for quick identification and understanding by any user.

The main categories of signage are:

• Prohibition Signs – indicate prohibited behaviors, such as “No smoking” or “No access” .
  
• Mandatory Signage – marks mandatory actions, such as "Mandatory use of helmets" or other personal protective equipment.
  
• Hazard/Warning Signage – alerts to hazardous situations, such as “Electrical Hazard” or “Flammable Materials” .
  
• Emergency and Rescue Signage – identifies emergency exits, evacuation routes, and first aid locations.
  
• Firefighting Signage – indicates the location of fire extinguishers, hoses, and other firefighting equipment.
  

Emergency signage and fire safety signage are especially important in businesses, industries, schools, and public spaces, as they ensure rapid responses in case of an accident.

In Portugal, all occupational health and safety signage is regulated by Decree-Law No. 141/95, which transposes European Directive 92/58/EEC, and supplemented by Portuguese Standards (NP).
