  • Specification

A Caution Site Entrance Sign is used to warn people that they are approaching or entering an active work area where hazards may be present. It helps alert visitors, workers and the public to proceed carefully before accessing the site.

At Foamex Printing Company, we supply Caution Site Entrance signs printed on rigid Foamex board, providing a clear and practical way to communicate caution at site access points.

These signs are suitable for construction sites, warehouses, factories, production plants and other working environments where a clear warning is required at an entrance.

Types of Site Entrance and Caution Signs

Different types of signage can be used at entry points depending on the information that needs to be communicated.

  • Site Entrance Sign: It provides a general notice identifying an access point. Where required, a site entrance sign can be used alongside more specific caution or safety messaging.
  • Caution Site Entrance Sign: It warns individuals that they are approaching or entering an active or potentially hazardous work area.
  • Construction Site Safety Sign: Additional safety signage can be positioned around construction areas to communicate important site instructions and warnings.

Caution signs can be positioned at entry gates, pedestrian access routes and other site access points where visitors, workers or members of the public need to be made aware of potential hazards before entering.

Materials, Printing, and Finish Options for Caution Signs

Our Caution Site Entrance signs are produced using a 3mm foamex board, a rigid and lightweight material commonly used for printed signage. The board provides a clean, stable surface for displaying the warning message clearly.

The signs are available in a range of standard sizes to suit different site entrances and display areas, with bespoke sizes and shapes also available where required.

Available options include:

  • 3mm Foamex board
  • Multiple standard sizes
  • Bespoke sizes and shapes
  • High-contrast printed graphics
  • Matt, gloss or dry-wipe finishes
  • Anti-graffiti finish

The choice of size and finish can be selected according to the intended display area and how the sign will be used. Clear positioning is also important to ensure the warning can be seen easily by people approaching the entrance.

For further guidance on signage placement, see our article on common mistakes to avoid with safety signs.

UK Requirements for Caution Site Entrance Signs

The design and use of workplace safety signs in the UK can be subject to relevant health and safety requirements, depending on the workplace, hazards and circumstances in which the signage is used.

A Caution Site Entrance Sign can be used to communicate a warning at an access point, but the sign itself does not determine whether a site meets its wider health and safety obligations. Appropriate signage should be selected and positioned according to the risks and requirements of the particular site.

22 Reviews for Caution Site Entrance Sign - CS12

Alethea Askew October 6, 2026

Had some questions about the correct wording for the site entrance sign to meet CDM requirements. The team were helpful in pointing me to the right information. The sign itself was produced correctly and delivered without delay.

Agape Anwyl September 21, 2026

First time using this company. The product arrived as described and the quality was better than the stock signage I'd been buying from a trade supplier. Will be making this the standard source for site entrance signage going forward.

Alexei Barnard July 31, 2026

For a project in an urban area with high public footfall past the site, visible and compliant entrance signage was a priority. The caution sign met the requirement and has had no issues through a busy period of works.

Ainnir Asgill July 27, 2026

Simple to install using the pre-drilled holes. Went up on the hoarding frame in minutes and reads clearly from both the footpath and the road. Does exactly what it needs to.

Anton Aitchison June 3, 2026

The sign survived a fairly brutal Scottish winter on an exposed site entrance without fading or losing its shape. That's the main test for outdoor safety signage and this one passed it.

Ailne Altrincham May 22, 2026

We run multiple sites and order caution entrance signs for each one. Foamex Printing Company has been reliable across every order — right product, right size, delivered on time. That consistency is worth something on a programme where delays have a cost.
