Safety barriers are only effective if they are in good condition. A corroded bollard, a loose Armco post, or a cracked plastic barrier provides much less protection than originally specified — and may expose the site owner to liability if a failure contributes to an accident.
The Legal Framework
- Occupier's Liability Act 1957: Occupiers owe a "common duty of care" to lawful visitors — ensuring premises are reasonably safe. A barrier that fails due to lack of maintenance is a clear breach.
- Occupier's Liability Act 1984: Extends liability to trespassers where the occupier is aware of danger and believes trespassers may be present.
- Health and Safety at Work Act 1974: Plant and systems of work must be maintained in a safe condition — explicitly includes safety barriers.
- Workplace (Health, Safety and Welfare) Regulations 1992: Regulation 5 requires all equipment to be maintained in efficient state, good working order, and good repair.
Recommended Inspection Frequency
| Barrier Type | Minimum Inspection Frequency | Additional Trigger |
|---|---|---|
| Steel bollards (fixed) | Annual | After any vehicle strike |
| Removable/telescopic bollards | 6-monthly | After vehicle strike; if mechanism becomes stiff |
| Automatic rising bollards | Quarterly (mechanical) + annual (structural) | After any impact or system fault |
| Armco highway barriers | Annual | After any reported vehicle impact |
| Warehouse barriers | Monthly (visual) + 6-monthly (structural) | After any forklift impact |
| Plastic/HDPE bollards | Annual | After severe weather; after vehicle strike |
| PAS 68/HVM barriers | 6-monthly + after any impact | After any significant impact event |
| Crowd control barriers | Before each event + annual storage inspection | After high-density crowd events |
Inspection Checklist by Barrier Type
Steel Bollards
- Corrosion at base/ground level — >20% section loss = replace
- Impact damage: deformation, bowing, displaced bollard
- Fixing: check anchor bolts or root concrete for movement
- Coating: check powder coat condition — re-apply if >50% coating lost from any face
- Cap: check domed/flat cap is secure
- Reflective banding: replace if dull or damaged
Removable Bollard Sockets
- Drainage: check socket is draining freely
- Locking mechanism: test removal/replacement — should operate freely
- Corrosion inside socket, particularly at the base
- Socket level: check top is flush with surrounding surface (trip hazard if raised)
Armco Barrier
- Post condition: bowing, cracking, or movement at ground level
- Rail condition: cracks, significant deformation, loose connections
- Bolts: check beam-to-post bolts are tight; replace corroded or missing bolts
- Galvanising: check condition; patch treat bare areas
- Terminals: check end terminals are correctly flared/capped and securely attached
Cleaning Methods by Material
| Material | Recommended Method | Avoid |
|---|---|---|
| Powder-coated steel | Warm soapy water and soft brush; rinse well. Pressure wash at ≤100 bar. Annual wax protection. | Abrasive cleaners; high-pressure (>150 bar); steel wool |
| Stainless steel | Warm water with stainless cleaner. Wipe in direction of grain. | Chlorine-based cleaners (pitting); steel wool; abrasives |
| Galvanised steel | Warm soapy water; rinse. Treat white rust with zinc-based paint if bare areas appear. | Acid cleaners; high-alkalinity cleaners (attack zinc) |
| HDPE/plastic | Warm soapy water; soft cloth or brush. Low-pressure wash. | Solvents; petroleum-based cleaners |
| Concrete | Pressure wash; specialist concrete cleaner for staining. | Acid-based cleaners |
When to Replace vs Repair
Replace when:
- Significant corrosion: >20% wall thickness section loss at any point
- Root/foundation compromised by impact or corrosion
- Bollard deformed by vehicle strike — structural integrity cannot be assumed
- Plastic bollard shows UV cracking or significant deformation
Repair/refurbish when:
- Coating has failed but substrate is intact — clean, prepare, repaint
- Cap is damaged — replacement caps available for most standard post diameters
- Reflective banding worn — adhesive retroreflective bands can be applied in the field
- Removable bollard socket mechanism stiff — clean and lubricate; replace locking pin if worn
PAS 68 / IWA 14 important note: Any structural damage must be assessed by the manufacturer before assuming the barrier remains rated — impact may have compromised the tested configuration.
Record Keeping
Maintain a barrier inspection log recording:
- Date of inspection
- Inspector name and competence
- Each barrier/bollard inspected (asset ID or location reference)
- Condition assessment: Good / Monitor / Action Required / Replace
- Actions taken (date of repair, replacement, or planned maintenance)
- Known impact events (date, nature of impact, damage assessment)
Retain records for a minimum of 6 years (limitation period for personal injury claims). Digital asset management systems make this straightforward for large sites.
Maintenance Contracts
For sites with large numbers of barriers, a planned preventative maintenance (PPM) contract typically covers:
- Annual structural inspection of all barriers and bollards
- Reactive callout for impact damage (typically 24–48 hour response)
- Replacement and repair works at agreed rates
- Inspection reports and electronic records
Cost: £15–£50 per barrier per year depending on site size and scope. Contact Barriers Co for maintenance contract pricing and nationwide coverage. Browse our barrier and bollard range.
