Pre-Installation Planning
1. Site Survey and Risk Assessment
Before purchasing or installing any signs:
Identify Hazards:
- Conduct thorough walkthrough
- Review existing risk assessments
- Consult with supervisors and employees
- Note areas of previous incidents
- Consider future workplace changes
Map Locations:
- Plot sign positions on floor plan
- Note viewing distances
- Identify potential obstructions
- Consider lighting conditions
- Plan for emergency evacuation routes
2. Regulatory Compliance Check
Ensure installations meet:
- BS EN ISO 7010:2020 (current standard)
- Health and Safety (Safety Signs and Signals) Regulations 1996
- Regulatory Reform (Fire Safety Order 2005)
- Industry-specific requirements (e.g., CDM 2015 for construction
3. Material and Fixing Selection
Match materials to environment:
- Indoor smooth surfaces → Self-adhesive vinyl
- Indoor permanent → Rigid plastic with screws
- Outdoor → Aluminium or weatherproof plastic
- High vandalism → Polycarbonate
- emergency routes → photoluminescent
Height and Positioning Requirements
Standard Mounting Heights
General Safety Signs:
- Optimal height: 1.5m to 2.0m (eye level)
- Measured from floor to sign center
- Adjust for average workforce height
- Consider wheelchair user sightlines
Fire Exit Signs:
- Above door frames: 300mm minimum above door
- Low-level: 300mm above floor (smoke visibility)
- Both positions recommended for comprehensive safety
warning Signs at hazard Points:
- Immediately before hazard: 2-5m approach distance
- At point of hazard: Eye level where safe
- Entry to hazardous zones: Door frame level
mandatory PPE Signs:
- Zone entry points: Before entry to area
- 1.8m height: Clear visibility
- Multiple positions: For large areas
Visibility Requirements
Signs must be visible from:
- All normal approach angles
- Expected working positions
- Adequate distance for action/decision time
- Without obstruction when doors/equipment operate
Minimum Viewing Distances:
Sign Size (mm) | Max Viewing Distance
150 x 150 | 10 metres
200 x 200 | 20 metres
300 x 300 | 30 metres
400 x 400 | 50 metres
600 x 600 | 75 metres
Lighting Considerations
Adequate Illumination:
- Minimum 50 lux at sign face
- Consider natural light variations
- Supplement with artificial lighting if needed
- Or use photoluminescent signs
Photoluminescent Requirements:
- Mandatory for emergency routes
- Must receive adequate light charging
- Minimum 54 lux for 15 minutes
- Test regularly for glow performance
Installation Methods
Method 1: Screw Fixing (Rigid Signs)
Best for: Permanent installations, rigid plastic, aluminium, polycarbonate
Tools Required:
- Spirit level
- Tape measure
- Pencil
- Drill with appropriate bits
- Screwdriver or drill driver
- Wall plugs (for masonry)
- Appropriate screws
Step-by-Step Process:
-
Position Sign:
- Hold sign at desired location
- Use spirit level to ensure horizontal
- Mark center point with pencil
-
Mark Fixing Holes:
- Mark all fixing hole positions
- Typically 4 corners for stability
- Large signs may need additional center fixings
-
Drill Pilot Holes:
- Select appropriate drill bit
- For masonry: Use masonry bit, insert wall plugs
- For wood/plaster: Smaller pilot hole prevents splitting
- For metal: Use metal drill bit
-
Fix Sign:
- Align sign with pilot holes
- Insert screws through sign into holes
- Tighten evenly, don't over-tighten
- Check level again
- Ensure sign sits flat against surface
Screw Selection Guide:
- Indoor/Dry: Standard steel screws
- Outdoor/Damp: Stainless steel or coated screws
- chemical environments: chemical-resistant fasteners
- Size: Appropriate for sign weight and material
Method 2: Self-Adhesive Installation (Vinyl Signs)
Best for: Smooth surfaces, non-permanent installations, lightweight signs
Surface Requirements:
- Smooth (not textured or rough)
- Clean and dry
- Free from grease/dust/moisture
- Temperature above 10°C during application
Tools Required:
- Cleaning cloth
- Degreaser/alcohol wipes
- Squeegee or soft cloth
- Tape measure
- Spirit level
- Pencil (for positioning marks)
Step-by-Step Process:
-
Surface Preparation (Critical):
- Clean thoroughly with degreaser
- Remove all dust, grease, and contaminants
- Dry completely
- For painted surfaces, ensure paint fully cured (28 days)
-
Position Marking:
- Measure and mark desired position
- Use spirit level for alignment
- Light pencil marks at corners
-
Application:
- Peel back 2-3cm of backing paper
- Align sign with position marks
- Slowly press down from one edge
- Gradually peel backing while smoothing sign
- Use squeegee to prevent air bubbles
- Work from center outward
-
Final Steps:
- Press firmly along all edges
- Pay special attention to corners
- Remove any air bubbles by pushing toward edge
- Allow 24 hours cure time before exposure
Temperature Considerations:
- Ideal application: 15-25°C
- Below 10°C: Adhesive may not bond properly
- Above 30°C: Difficult to handle, may bubble
Common Failure Causes:
- Surface not clean/dry
- Application in cold conditions
- Insufficient pressure on edges
- Premature exposure to weather
Method 3: Cable Tie Fixing (Mesh/Fencing)
Best for: Wire mesh, chain link fencing, temporary barriers
Tools Required:
- UV-resistant cable ties
- Cable tie gun or pliers
- Wire cutters

Process:
- Position sign on mesh/fencing
- Thread cable tie through sign holes and mesh
- Pull tight with cable tie gun
- Cut excess tie length
- Use minimum 4 cable ties per sign
- Check regularly and replace degraded ties
Method 4: Magnetic Fixing (Temporary)
Best for: Temporary signs on steel surfaces (e.g., vehicles, containers)
Requirements:
- Ferrous metal surface
- Clean, smooth surface
- Strong neodymium magnets for outdoor use
Process:
- Clean metal surface
- Attach magnetic fixings to sign
- Position carefully (strong magnets attract suddenly)
- Check security regularly
- Remove during high winds if lightweight
Limitations:
- Only on ferrous metals
- Regular checking essential
- Not for permanent installations
- Can be removed by others

Common Installation Mistakes
Mistake 1: Incorrect Height
Problem: Signs too high or low for optimal visibility
Solution: Follow 1.5-2.0m guideline, adjust for specific situations
Mistake 2: Obstructions Ignored
Problem: Sign hidden when doors open, equipment moved, or seasonal changes
Solution: Test all operational scenarios before final fixing
Mistake 3: Poor Surface Preparation
Problem: Self-adhesive signs fall off within days
Solution: Thorough cleaning, degreasing, and drying before application
Mistake 4: Wrong Fixing Method
Problem: Rigid signs with adhesive backing on textured walls
Solution: Match fixing method to sign material and surface type
Mistake 5: Inadequate Size
Problem: Sign too small for viewing distance
Solution: Use viewing distance chart to select appropriate size
Mistake 6: No Photoluminescent on Fire Exits
Problem: Exit signs invisible during power failure
Solution: Always use photoluminescent or emergency lit signs
