Walk any busy site and you see the same pattern. Blue circles tell people what they must do. Hard hats, eye protection, wash stations. These signs are not decoration, they are legal tools that reduce risk.
If you manage UK sites, review your mandatory signs with a marketer’s eye. You do not need a redesign. You need small, careful tweaks that keep compliance first and help your brand speak clearly in the same space.
Keep compliance first
Compliance is non-negotiable. In the UK, mandatory signs use a blue circle with a white symbol to state an action that people must take, like Wear eye protection. The layout and colors are not a style choice.
They follow recognized standards so anyone can understand them at a glance. The blue field and white pictogram must stay intact. That is the line you never cross.
Check your signs against official guidance before any brand update. Confirm symbol shape, color, wording, size, and placement. If a sign is faded or the blue looks washed out, replace it.
A crisp sign is safer, and it also reflects well on your brand. The best brand move with safety signs is to keep them easy to read, clean, and where people expect to find them.
Add brand around the sign
Think of the mandatory sign as the core message. Your brand can live in the space around it. Use a neutral backer panel in your brand white or light gray, then mount the sign on it. Keep enough clear space so the blue circle still pops.
If the area needs a headline, place it above the sign on the backer panel, not inside the blue circle. Keep the headline short, like Safety first in this area. Use your brand typeface if it is legible and simple, or use a clean sans serif if legibility is in doubt.
You can add a small brand mark on the backer panel or in the bottom corner of a multi-sign board. Keep the mark modest. The safety message must be the most visible part. A helpful test is to take two steps back. If your logo competes with the symbol, reduce it.
Use color in safe ways
Mandatory symbols are blue and white. Do not recolor them. If you want brand color on site, use it in frames, rails, stanchions, or backing boards. A slim frame in a brand accent can guide the eye toward the sign while keeping the symbol pure.
On printed sign clusters, use brand color as a light divider line between different sign types. Keep contrast high and avoid bright tints that reduce readability in glare.
For teams that use wayfinding stripes on walls or floors, pick a distinct pattern for safety zones. A brand colored stripe can lead to a wash station or PPE point, ending at a board with the correct blue circular signs. The color helps people find the area.
Support with clear text
Pictograms are powerful, but short words help in noisy or low light settings. Add a clear line of text under the symbol, such as Wear hard hat.
Use plain English, sentence case, and a readable typeface. Do not turn the message into marketing copy. People should grasp it in one second.
If your sites host many first time visitors or speakers of other languages, support the main line with a translation line on the backer panel or on a nearby info strip.
Keep text large and avoid jargon. Test print a sample and tape it in place for a week. Ask workers if it reads fast. Adjust before ordering in bulk.
Add QR codes for more info
A sign tells you what to do. A code can tell you why and how. Place a small QR code near the sign, on the backer panel or on a nearby info strip. Link to a short mobile page with an explainer video, a site induction clip, or a checklist.
The code should be far enough from the sign that no one confuses it with the mandatory symbol. Keep the landing page light, fast, and readable with gloves on and in bright sun.
Use tracking to see which signs get scans. If eye protection signs get many scans during a project phase, plan a short toolbox talk. If a code never gets used, move it to a more visible spot or trim the content.
Group signs on boards
People process clusters better than scattered signs. Build task boards that group the right mandatory signs for a zone. Above the cluster, add a board title in your brand typeface, like PPE for this area.
Put a small brand mark on the board edge, not near the symbols. Keep the board simple and consistent across sites so visitors learn the pattern. When the layout is predictable, the brain works less to find the rule and more to follow it.
If you run many temporary sites, print a modular board with rails and slide-in holders. This lets teams swap signs as tasks change, while the board title and brand frame stay the same. The result is tidy, fast to update, and friendly to audits.
Pick durable materials
Material says a lot about care. A rigid aluminum sign stays flat and clean. A good laminate resists sun and solvents. Rounded corners reduce snags. Anti-graffiti coatings make cleaning faster.
Match sign durability to the risk and the environment. A muddy yard needs tough, wipeable surfaces. A clean food area needs smooth edges and strong contrast.
If your brand values sustainability, choose recycled substrates where they meet durability needs. Keep print quality high so the blue field stays even. A sign that fades or curls sends the wrong message about care and control.
Place signs where people look
A perfect design fails if no one sees it. Use sightline rules. Mount at eye level near the point of decision. Place eye protection signs before a cutting bay, not inside it. Keep signs clear of clutter, glass reflections, and moving equipment.
Repeat key signs along long routes where people join from different directions. Check visibility in rain, fog, and at dusk. Night shift teams need the same clarity as day shift teams.
Run a simple walk test with a site lead, a new starter, and a visitor. Ask each one to find the right PPE board and explain what they must do. Time the task. If it takes more than a few seconds, adjust placement or add a repeated sign on the approach.
Track and improve
Treat your sign plan like any other marketing asset. Set a baseline, then track. Note near misses tied to missed instructions and see if clearer signs and boards reduce them. Track QR scans, training attendance, and audit notes. Ask supervisors which boards get the most questions.
Small changes, like larger text or a better backer color, can cut confusion in one day.
Document your final layouts and specs. Keep a simple playbook that lists approved symbols, text styles, mounting heights, materials, and the allowed places for brand marks.
Share it with procurement so orders stay consistent. Update the playbook once or twice a year after safety reviews.

Practical takeaway
Start by auditing your current signs. Fix compliance issues first. Then add brand touches around, not inside, the blue symbols. Use frames, backer panels, short headlines, and tidy boards.
Add QR codes for depth where they help, not everywhere. Place signs where eyes land, and measure results. Done well, your brand looks careful and professional, and people on site get the clear guidance they need.
