Types of Safety Signs

  • Mandatory Signs 

Mandatory signs show an action that people must take. They normally use a white symbol on a blue circular background. 

Examples include wear a hard hat, use eye protection, keep fire doors shut and wear high visibility clothing. 

  • Warning Signs 

Warning signs alert people to a hazard or source of danger. They normally have a yellow triangular background with a black border and symbol. 

They can be used to mark electrical risks, moving vehicles, slippery floors, hot surfaces, hazardous substances and other site specific dangers. 

  • Prohibition Signs 

Prohibition signs show that an action is not allowed. Their familiar red circle and diagonal bar make restrictions quick to recognise. 

Typical messages include no smoking, no entry, do not touch and no unauthorised access. 

  • Emergency Signs 

Emergency signs help people find safe routes, first aid facilities and emergency equipment. They normally use a white symbol or text on a green rectangular or square background. 

Examples include first aid points, emergency exits, escape routes and assembly points. 

  • Fire Safety Signs 

Fire signs identify fire exits, alarm call points, extinguishers, fire action instructions and assembly areas. 

We offer a dedicated range of Fire Safety Signs, including photoluminescent options for improved visibility in low light. 

  • Construction & Site Safety Signs 

Construction signs need to remain clear in busy, changing and exposed environments. 

We can produce entrance boards, personal protective equipment notices, hazard warnings, restricted access signs, directional signs and custom site rules boards.  

  • Custom Safety Signs 

Not every premises can be covered by a standard sign. A custom safety sign may be needed for a particular machine, restricted area, site rule, access route or operating procedure.

Safety Sign Materials

The right material depends on the location, expected lifespan and fixing surface. We supply safety signage in the following materials: 

  • Self adhesive vinyl for smooth surfaces, doors, windows and equipment  
  • Foamex for lightweight rigid signs used indoors or in suitable outdoor locations  
  • Correx for lightweight and temporary site boards  
  • Aluminium composite, also known as Dibond, for strong and durable indoor or outdoor signs  
  • Aluminium for durable signage where a robust finish is required  
  • Photoluminescent material for selected fire and emergency signs that need to remain visible in low light  

Tell us where the sign will be fixed and how long it needs to last. We will help you choose an appropriate option rather than using the same material for every application.

Where Safety Signs Are Used

Construction sites

Safety signs help communicate site rules, PPE requirements, hazards and restricted areas across busy construction environments. Clear signage also guides workers, visitors and contractors safely around entrances, work zones and access points.

Offices

Office safety signs highlight fire exits, first aid points, emergency procedures and areas where specific precautions are required. They help employees and visitors quickly understand important safety information throughout the workplace.

Warehouses

Warehouses use safety signs to warn about moving vehicles, machinery, restricted zones and other potential hazards. They can also mark safe routes, emergency exits and areas where protective equipment must be worn.

Schools

Safety signs in schools help pupils, staff and visitors identify emergency exits, fire safety equipment, restricted areas and potential hazards. Clear, easy-to-recognise signage supports a safer environment across classrooms, corridors and shared spaces.

Industrial premises

Industrial premises rely on safety signage to communicate machinery hazards, mandatory PPE, prohibited activities and safe working procedures. Durable signs can be positioned throughout production areas, workshops and access points to keep essential instructions visible.

Commercial buildings

Commercial buildings use safety signs to provide clear information about emergency routes, fire equipment, restricted access and general workplace hazards. Appropriate signage helps employees, customers, contractors and visitors navigate the premises safely.

Designing & Installing Safety Signs

Send us your finished artwork or explain what the sign needs to communicate. Our team will review the purpose, location, viewing distance and indoor or outdoor use before recommending a suitable format. 

If artwork is needed, our designers can create a clear layout based on your brief and provide a preview before production. 

Once approved, the signs are printed and checked before delivery. Most custom signage projects are produced within 3 to 7 working days, depending on the size and complexity of the order. Urgent work may be fast tracked on request. 

Professional installation is also available. This is useful for larger boards, groups of signs and locations where secure and accurate placement matters.
