Prohibition signs play a crucial role in maintaining safety and order in various environments. They are designed to prevent hazards and regulate behaviour by clearly indicating actions that must not be taken. This guide will provide an in-depth overview of prohibition signs, their legal basis, applications, and guidance on selecting and positioning them effectively. 

What Is a Prohibition Sign? 

Prohibition signs are visual indicators that communicate actions that are not allowed. Common examples include "No Smoking", "No Access", and "No Mobile Phones". These signs are essential for preventing accidents and ensuring compliance with safety regulations. 

The Role of Prohibition Signs 

Prohibition signs help in preventing hazards and regulating behaviour by providing clear instructions on what actions are prohibited. They are a fundamental aspect of safety management systems in workplaces and public areas. 

Legal and Standard Context 

Prohibition signs are governed by specific standards, such as the BS EN ISO 7010 symbol P-series, which ensures consistency and recognisability across different regions. Employers and occupiers have a legal responsibility under health and safety laws to implement effective signage to mitigate risks and demonstrate compliance. 

Importance of Correct Signage 

Using the correct prohibition signs is crucial for liability and compliance. Proper signage helps in avoiding legal issues and ensures that safety measures are visibly enforced. 

Common Types and Applications 

Prohibition signs are used in various settings, each with specific applications: 

  • No Smoking / No Open Flames: Commonly used in areas with flammable materials. 

  • No Vehicles: Applied in pedestrian zones or areas where vehicle operation is restricted. 

  • No Mobile Phones / No Photography: Site-specific signs used in areas where electronic devices are prohibited. 

These signs are prevalent in construction sites, manufacturing plants, chemical stores, offices, and public spaces. 

How to Select, Design, and Place Prohibition Signs Effectively 

When selecting prohibition signs, it's essential to adhere to standard designs: a red circle with a slash, a black pictogram on a white background. Compliance with BS/ISO standards is crucial. 

Key Considerations 

  • Size, Durability, and Material: Choose appropriate materials for indoor and outdoor use to ensure longevity. 

  • Placement: Signs should be placed at the point of decision, at eye level, unobstructed, and repeated as necessary. 

  • Customisation: Custom signs may be required where standard messages are insufficient. Consider multi-language options and emphasised pictograms. 

  • Maintenance: Regular checks are necessary to prevent fading, peeling, or obstruction. 

Common Mistakes That Reduce Sign Effectiveness 

To maximise effectiveness, avoid common pitfalls such as:

  • Using text-only signs without pictograms, which reduces clarity. 

  • Placing signs too far from the location of the prohibited action. 

  • Over-signing, which can desensitise staff and visitors. 

  • Using outdated symbols or non-UK/European formats.
