Mandatory Signs (Blue Circle Signs): PPE and Action Requirements

Overview

Understanding mandatory signs that require specific actions or personal protective equipment in your workplace. This comprehensive guide covers everything you need to know about selecting, installing, and maintaining these critical safety signs.

Regulatory Framework

These signs are required under:

• Health and Safety (Safety Signs and Signals) Regulations 1996
• BS EN ISO 7010:2020 (current standard)

When These Signs Are Required

According to UK regulations, safety signs must be provided where:

1. Risks remain after other control measures
2. Quick recognition is essential for safety
3. Emergency information must be conveyed
4. Mandatory actions are required
5. Prohibited behaviours must be prevented

Sign Design and Standards

Colour Coding

Each safety sign category uses specific colours with defined meanings:

• Red - Prohibition and fire equipment
• Yellow/Amber - Warning of hazards
• Blue - Mandatory actions required
• Green - Safe conditions and emergency information

Shape Requirements

BS EN ISO 7010:2020 specifies:

• Circles - Prohibition and mandatory signs
• Triangles - Warning signs
• Rectangles/Squares - Information signs

Pictograms

Standardised symbols ensure universal understanding across:

• Language barriers
• Literacy levels
• Cultural differences
• International workforces

Material Selection Guide

Choose sign materials based on your environment:

Indoor Applications

• Gloss white finish
• 5-7 year lifespan indoors

Self-Adhesive Vinyl

• Quick installation
• Ideal for smooth surfaces
• No drilling required
• 3-5 year lifespan indoors

Outdoor Applications

Aluminium Composite

• Excellent weather resistance
• UV stable colours
• 10+ year lifespan
• Premium appearance

Rigid Plastic (Heavy Duty)

• Impact resistant
• Weather resistant
• Cost-effective
• 7-10 year lifespan outdoors

Special Requirements

Photoluminescent

• Emergency applications
• Glows in darkness
• Meets PSPA Class C
• Essential for fire exits

Polycarbonate

• Vandal resistant
• High impact strength
• Transparent available
• High-risk areas

Installation Requirements

Height and Positioning

• Standard mounting height: 1.5m to 2.0m (eye level)
• Fire exit signs: Above door frames or 300mm above floor level
• Warning signs: At point of hazard or entry to hazard zone
• Mandatory signs: At entry to areas where PPE required

Visibility Requirements

Signs must be:

• Adequately lit or photoluminescent
• Unobstructed from normal viewing positions
• Appropriate size for viewing distance
• Clean and legible at all times

Size Calculations

Minimum size based on viewing distance:

| Viewing Distance | Minimum Sign Size | |-----------------|-------------------| | Up to 10m | 150mm x 150mm | | 10m - 20m | 200mm x 200mm | | 20m - 30m | 300mm x 300mm | | 30m - 50m | 400mm x 400mm |

Fixing Methods

Screw Fixing

Best for: Permanent installations on wood, plaster, metal

• Mark fixing holes
• Drill appropriate pilot holes
• Use wall plugs if required
• Secure with appropriate screws

Self-Adhesive

Best for: Smooth, clean, dry surfaces

• Clean surface thoroughly
• Remove backing paper
• Apply from one edge, avoiding bubbles
• Press firmly, especially edges
• Allow 24 hours before exposure to weather

Cable Ties

Best for: Wire mesh fencing, chain link, barriers

• Use UV-resistant ties outdoors
• Multiple fixing points for large signs
• Check tightness regularly
• Replace degraded ties

Magnetic Fixings

Best for: Temporary signs on steel surfaces

• Clean metal surface
• Strong magnets for outdoor use
• Regular checking required
• Limited to ferrous surfaces

Maintenance Requirements

Regular Inspection Schedule

• Weekly: Visual check for damage in high-traffic areas
• Monthly: Clean signs, check fixings
• Quarterly: Detailed inspection, replace damaged signs
• Annually: Full audit against risk assessment

Cleaning Guidelines

1. Use mild detergent and water
2. Soft cloth or sponge only
3. Avoid abrasive cleaners
4. Rinse with clean water
5. Dry thoroughly

Replacement Indicators

Replace signs when:

• Colours faded (difficult to identify type)
• Physical damage (cracks, chips, bent)
• Text illegible from distance
• Fixings failing
• Signs outdated (pre-ISO 7010)

Real-World Case Study

Manufacturing Facility Compliance Project

Challenge: 15,000 sq ft facility with outdated signage, mixed standards, poor visibility in some areas.

Solution:

1. Comprehensive site audit
2. Risk assessment review
3. BS EN ISO 7010:2020 compliant sign package
4. Zone-based approach to PPE requirements
5. Photoluminescent emergency route marking

Results:

• 100% regulatory compliance achieved
• Passed HSE inspection without recommendations
• 40% reduction in near-miss incidents
• Improved employee safety awareness
• Insurance premium reduction

Common Mistakes to Avoid

1. Wrong Sign Type for Hazard

Using warning signs where prohibition signs are required creates confusion and legal non-compliance.

2. Inadequate Size

Signs too small for viewing distance fail to communicate effectively and don't meet regulations.

3. Poor Positioning

Signs obscured by doors, equipment, or at wrong heights reduce effectiveness significantly.

4. Mixed Standards

Combining old and new symbol systems creates confusion—update all signs together where possible.

5. Neglecting Maintenance

Faded or damaged signs give impression of poor safety culture and may not protect legally.

Training Requirements

Ensure all employees understand:

• What signs mean - Each symbol and colour
• Required actions - What they must do
• Why signs matter - Legal and safety reasons
• Reporting damage - Who to inform immediately

Cost-Benefit Analysis

Investment in proper signage:

• £2,000 - £5,000 typical small business
• £10,000 - £25,000 medium facility
• £50,000+ large industrial site

Potential costs of non-compliance:

• £15,000 - £50,000 average HSE fine
• £50,000 - £500,000 serious injury litigation
• Unlimited fines for fatal incidents
• Insurance premium increases
• Reputational damage
• Business interruption
