Types of Industrial Signs in the UK

Industrial signs tell you what you must do, what to avoid, what hazards exist, and where safety equipment and routes are located. You will find standard colours, shapes and symbols used across sites to ensure quick recognition and legal compliance.

Mandatory Signs

Mandatory industrial signs require specific actions you must take to remain compliant and safe. They are circular with a blue background and white pictogram or text. Common examples include "Wear Eye Protection", "Wear Safety Helmets" and "Hearing Protection Must Be Worn".

Display these industrial signs where a particular action is compulsory, such as at the entrance to machining areas, chemical stores or confined spaces. Check that pictograms follow BS EN ISO 7010 and that signs are positioned at eye level, unobstructed, and weatherproof for outdoor use.

Maintain legibility by replacing signs when faded or damaged. Use supplementary text only if the pictogram alone cannot convey the instruction; keep wording short and direct, for example: "Wear protective gloves beyond this point."

Warning Signs

Warning industrial signs alert you to potential hazards that could cause injury or damage if you do not take care. They are triangular with a black pictogram on a yellow background and a black border. Examples include warnings for "Flammable Material", "Crushing Hazard" and "High Voltage".

Place warning industrial signs where specific risks are present: near machinery with moving parts, at changes in floor level, and beside storage of hazardous substances. Ensure the symbol matches the actual risk and that signs are visible from typical approach paths to give you time to react.

Supplementary plates can clarify the hazard or state safe distances. Regular risk assessments should verify that each warning sign remains relevant; remove or replace signs when conditions change.

Prohibition Signs

Prohibition industrial signs tell you what actions are forbidden to prevent accidents or breaches of safety policy. They are circular with a red ring and diagonal bar over a black pictogram on a white background. Typical examples are "No Smoking", "No Entry for Unauthorised Persons", and "Do Not Use Mobile Phones".

Use these industrial signs at points where the forbidden act would create a specific danger: gas storage areas (no smoking), plant rooms (no unauthorised access), and areas with explosive atmospheres (no ignition sources). Position signs at entrances and repeat them at intervals in larger spaces.

Ensure enforcement measures and local rules back up the sign. Where necessary, add short explanatory text beneath the symbol, such as "No unauthorised access — PPE required beyond this point."

Safe Condition Signs

Safe condition industrial signs indicate routes, exits and locations of safety equipment you can use in an emergency. They are rectangular or square, green with white pictograms or text. Common examples are "Emergency Exit", "First Aid Station", and "Eye Wash".

Install these industrial signs so you can clearly see escape routes and safety equipment from normal viewpoints. Emergency exit signs should be illuminated or photoluminescent where power may fail. First aid and fire equipment signs must be sited adjacent to the equipment they denote.

Check that symbols comply with BS EN ISO 7010 for immediate recognition. Carry out routine inspections to confirm signs remain visible, unobstructed and correctly oriented toward the exit or equipment they identify.

UK Legal Requirements for Industrial Signage

You must ensure industrial signs meet statutory duties, follow recognised standards, and reflect documented risk assessments. This prevents regulatory breaches, reduces workplace incidents, and supports compliance records.

Health and Safety Regulations

You must comply with the Health and Safety at Work etc. Act 1974 and the Management of Health and Safety at Work Regulations 1999. These place a duty on employers to provide information, instruction and training; signage forms part of that information where hazards cannot be controlled by other means.

Use industrial signs to warn of residual risks, indicate mandatory actions (e.g. PPE zones) and show emergency routes and equipment. The Regulatory Reform (Fire Safety) Order 2005 requires clear fire exit and evacuation signage. Make sure signs are visible in all lighting conditions and maintained so that reflectivity and legibility remain effective.

Record signage locations and maintenance in your safety management system. Inspect industrial signs regularly and log replacements or repairs. Non-compliance can result in enforcement notices, fines or prosecution, so keep documentary evidence of your decisions and actions.

British Standards Compliance

You should follow relevant British Standards, primarily BS 5499 (safety signs) and BS EN ISO 7010 (graphical symbols). These standards standardise colours, shapes and pictograms so industrial signs are immediately recognisable and reduce ambiguity across sites.

For fire safety signs, use BS 5499 conventions and ISO 7010 symbols for consistency. For hazardous substances and COSHH-related signage, align with the Classification, Labelling and Packaging (CLP) Regulation and Refer to Health and Safety Executive (HSE) guidance for substance-specific requirements.

Ensure your supplier, such as The sign company, can provide certificates of conformity and that materials meet durability expectations for your environment (chemical resistance, UV stability, temperature tolerance). Keep copies of standards referenced in your risk assessments and safety documentation.

Risk Assessment Considerations

You must base industrial sign selection and placement on documented risk assessments under the Management of Health and Safety at Work Regulations. Identify hazards, the people at risk, and whether signage alone is sufficient or a supplementary control.

Assess visibility factors: viewing distance, mounting height, lighting, obstructions and worker PPE that may impede recognition. Consider multilingual requirements, literacy levels and the need for pictograms for diverse workforces.

Prioritise industrial signs where controls are residual or where rapid action is required—emergency stops, isolation points, and high-risk machinery. Review signage whenever processes, layout or personnel change, and update risk assessments accordingly.

Design and Material Options for Industrial Signs

This section focuses on material choices for longevity, visible options for low-light conditions, and the customisation features that affect compliance, durability and installation ease.

Durable Materials

Choose materials suited to the environment and expected lifespan. For outdoor yards and loading bays, aluminium composite panels (ACM) and solid aluminium resist corrosion and weigh less for easier mounting. Marine-grade stainless steel (316) works where chemical exposure or salt spray is present; it costs more but reduces replacement frequency.

For abrasive indoor environments and workshops, polycarbonate and high-density polyethylene (HDPE) stand up to impact and chips. Use UV-stable grades to avoid brittleness and colour fade. Specify thickness (3–6 mm for small signs; 6–10 mm or more for larger panels) and edge treatments to prevent delamination.

Consider substrate finish: powder-coated surfaces offer durable colour and scratch resistance, while anodised aluminium gives a thin, hard protective layer. Fastening points and recommended fixings (through-bolts, rivets, magnetic mounts) should match material strength to prevent sagging or tear-out.

Customisation Choices

Decide on size, layout and regulatory content early to avoid remakes. Standard sizes speed manufacture; bespoke dimensions suit odd mounting locations. Include a clear zone around text (minimum 10–15 mm) to preserve legibility from typical viewing distances.

Colour and typeface matter for compliance and readability. Use RAL or Pantone codes for exact colour matching and choose sans-serif fonts like Arial or DIN for high legibility. Add pictograms compliant with ISO 7010 when conveying hazards; provide vector files (SVG, EPS) to keep edges crisp at any scale.

Surface finishes and protective laminates affect lifespan. Anti-graffiti coatings, matt or gloss laminates, and tamper-resistant fixings reduce maintenance. Include QR codes or NFC tags embedded behind a clear layer for asset tracking without altering appearance.

Reflective and Illuminated Signs

Select reflective grades by viewing distance and vehicle speed. For traffic-facing industrial signs inside industrial estates, use Class 1 (engineer grade) for short-range visibility and Class 2 (high-intensity) or Class 3 (prismatic) for higher-speed approaches. Specify the retroreflective standard (EN 12899-1 or BS EN 12899) in the order.

For illuminated industrial signs, choose between edge-lit acrylic panels, backlit LED boxes, and internally illuminated aluminium tray signs. LEDs offer low power consumption and modular replacement. Ensure IP ratings (IP65 or above) for external fixtures and include surge protection and thermal management in the specification.

Consider fail-safe requirements: use redundant LED circuits, battery-backed emergency illumination for escape-route signs, and clearly mark power supplies. Include photometric data and installation instructions so installers can meet lux and uniformity requirements on site.

Choosing an Industrial Sign Supplier in the UK

Select a supplier that demonstrates proven performance, clear timelines, and reliable post-sale care. Focus on credentials, realistic lead times, and the scope of after-sales support to avoid delays and compliance issues.

Evaluating Supplier Credentials

Check company registration and industry memberships such as the British Sign & Graphics Association (BSGA). Request copies of public liability insurance, ISO 9001 certification, and British Standards compliance for materials and mounting systems.

Ask for case studies and client references from sites similar to yours — warehouses, chemical plants, or transport hubs. Verify past projects with on-site photos and contactable referees. Inspect portfolio details: substrate types, photoluminescent performance (if applicable), and durability testing results.

Confirm in-house capabilities versus subcontracting. If they outsource aluminium fabrication or digital printing, get names and quality assurances. Review sample panels for print resolution, edge finishing, and fixings. Demand a written Quality Assurance process and a warranty document that specifies duration and cover.

Lead Times and Delivery

Obtain a written production schedule that breaks down design approval, prototyping, production, and delivery stages. Require explicit turnarounds for bespoke aluminium panels, vinyl overlays, and photoluminescent castings rather than a single vague lead time.

Ask about peak-season variations and current factory capacity. Confirm whether The sign company holds common stock items (e.g., safety pictograms, standard wayfinding panels) to reduce wait time. For large or phased projects, request batch delivery options and staged sign roll-outs.

Clarify shipping methods, carrier names, and liability during transit. For site installations, confirm access requirements, crane or MEWP provision, and estimated installation windows. Include penalties or rebates in the contract for missed deadlines where delivery timing is critical.

After-Sales Support

When choosing industrial signs for your business, especially from The sign company, seek a clear warranty that lists covered faults such as fading, material failure, and adhesive breakdown, as well as exclusions like damage from misuse or site chemicals. It's important that the warranty period matches the expected service life of the industrial signs specified in your project documents.

Confirm with The sign company the repair and replacement procedures, including typical response times and whether they supply temporary industrial signs while resolving issues. Ask if they keep spare panels or templates for rapid remakes of industrial signs.

Check if The sign company offers ongoing maintenance contracts, including scheduled inspections, re-fastening, and cleaning protocols for different substrates. Ensure technical documentation and fixing details are provided, including fixings torque, sealant types, and recommended cleaning agents for your industrial signs.
