The History of Health and Safety Signs in the UK

…and How Morelock Signs Carries the Torch — With ISO 9001 Quality & Strong Social Values

Health and safety signs are everywhere in modern Britain — from warehouses and offices to schools, construction sites, and public venues. But how did they become so standardised, and where does Morelock Signs fit into that story?

⚙️ The Early Days: No Rules, No Standards

1800s – Early 1900s
During the Industrial Revolution, Britain’s factories, railways, and mines operated with minimal formal guidance.
Signage was homemade, text-only, and inconsistent, leaving non-English speakers and low-literacy workers at risk.
Safety notices were optional and unenforced — signage was an afterthought.

🏭 A Shift Towards Safety — The 1960s & 70s

Factories Act 1961: First UK law to mandate certain safety notices.
BS 5378 (1970s): Britain’s first standard introducing colour coding and unified pictograms.
🔴 Red = Prohibition 🟡 Yellow = Warning 🔵 Blue = Mandatory 🟢 Green = Safe Condition
Morelock Signs adopted these principles early, shaping much of the visual language we still use today.

📋 1974: The Game-Changer

The Health and Safety at Work etc. Act 1974 placed a legal duty on employers to protect workers — including providing proper signage.
The HSE (Health and Safety Executive) gained enforcement powers.
Demand for compliant, high-visibility signs surged, and Morelock Signs expanded to meet that need.

🌍 European Alignment — The 1990s

Safety Signs & Signals Regulations 1996 transposed EU Directive 92/58/EEC into UK law, setting:

• Standard pictograms recognised across Europe
• Minimum size, colour-contrast, and placement rules
  Morelock Signs aligned every design and production workflow to keep customers effortlessly compliant.

📐 Modern Day: ISO 9001-Certified Quality Management

Morelock Signs operates under ISO 9001, the world’s leading quality-management standard.
That means every stage — from artwork approval to dispatch — is audited, documented, and continuously improved.
You receive consistent, reliable products with full traceability.
