Permanent collective protection — the standard, not the exception
Why Protector GuardrailProtector Guardrail
Four dimensions on which Protector Guardrail defines the category of industrial safety. Structural engineering combined with regulatory excellence.
01 — Duration of protection
Permanent safety, no temporary risks
The market often wrongly compares permanent systems against EN 13374. This is a standard for temporary construction-site edge protection (max. 6 months) that must already be dismantled at wind force 6. A ‘temporary’ solution on a permanent building is technically irresponsible and brings risks and unnecessary costs.
Protector Guardrail is the only structural, permanent solution. Discover the difference:
Temporary systemProtector Guardrail
| Criterion | Temporary system | Protector Guardrail |
|---|---|---|
| Availability | Temporary system: Only during setup | Protector Guardrail: Always present |
| Wind load | Temporary system: Limited(storm-sensitive) | Protector Guardrail: Structurally calculated(EN 1991) |
| Risk profile | Temporary system: Risk at every assembly and dismantle | Protector Guardrail: Safe basis(one-time) |
| PPE & rescue | Temporary system: Annual inspection and rescue plan required | Protector Guardrail: Not needed |
| Documentation | Temporary system: Often incomplete | Protector Guardrail: Full lifecycle dossier |
| TCO (25 years) | Temporary system: High — recurring per deployment | Protector Guardrail: One-time investment |

02 — Legal hierarchy
Individual PPE: the last resort, not the solution
Under EU Directive 89/391/EEC, safety managers are legally required to give collective measures priority over individual protection.
- 01Primary measure
Collective protection
Required by law before any individual measure is considered.
- 02Derogation
Organisational measures
Permitted only when collective protection is technically infeasible.
- 03Last resort
Individual PPE
Documented justification required when tiers 01 and 02 cannot apply.
03 — Behaviour independence
A system that works regardless of what anyone does
No training dependency
Unlike lifeline systems, Protector Guardrail requires no certification, annual training, or specific user knowledge to prevent a fall.
No supervision required
Eliminate the liability of checking whether workers are correctly harnessed. The structure is the supervisor.
No gaps
Human error causes 85% of roof incidents. Protector Guardrail removes the human variable from the safety equation entirely.
04 — Visit frequency
How often does someone stand on your roof?
Select what is on the roof. We calculate the visit frequency and annual cost of temporary edge protection — and the year in which permanent edge protection becomes cheaper.
m
The perimeter to be protected, in linear metres.
Adjusted to the allowed range of 10 to 2,000 m.

Break-even — legible, project-specific
Not a single number, but a matrix. Pick the perimeter and visit frequency that match your roof — and read the break-even year straight off.
Break-even by perimeter × visit frequency

06 — Case in practice
De Sting Tilburg — €45,517 saved over 20 years
The per-metre and per-installation-type matrices above show how the payback builds up. Below is one concrete project: 500 m of roof edge, 20 years in service, compared with the cable-system alternative originally proposed.

Net saved · 20-year total
Break-even after 4 years.
The installation costs more at handover, but the cable system generates inspection and training costs every year that overtake the extra CAPEX within four years. After that, 16 years of net return.
