Installation of Fall Protection Systems and Lifelines
(UNI 11560:2022 – UNI 11900:2023)

The installation of permanent fall protection systems is a highly specialized technical activity that must ensure full consistency between the design, the device, and the supporting structure.
Installation must comply with the principles set out in UNI 11560:2022, which governs the criteria for installing anchorage systems on roofs, and UNI 11900:2023, which defines the competencies and responsibilities of the qualified installer.

The objective of installation is to ensure that the fall protection system, once installed, meets the design performance requirements in terms of strength, stiffness, functionality, and durability, and that it is safe for users.

Technical and regulatory requirements for installation

UNI 11560:2022 – Installation in accordance with the design

The standard requires that installation:

  • is carried out strictly in accordance with the executive design, without unauthorized modifications by the designer;

  • complies with the manufacturer’s specifications for the fall protection system;

  • ensures correct mechanical connection between the device and the supporting structure, based on the structural verifications performed (NTC and Eurocodes);

  • includes inspection of materials, fixings, and substrate conditions prior to installation;

  • provides for an installation inspection certifying compliance of the installed system with the design requirements.

UNI 11560:2022 emphasizes that installation is an integral part of the design process: a correctly designed system may become ineffective if installed improperly.

Installer Qualification (UNI 11900:2023)

Standard UNI 11900:2023 defines the competencies of anchorage system installers, identifying three professional levels:

  • Basic Installer – Performs installation activities and installation inspection.
  • Intermediate Installer – Also carries out periodic inspections required by the manufacturer.
  • Advanced Installer – Qualified to perform extraordinary inspections, corrective actions, and complete system replacements.

A fall protection system installed by unqualified personnel may compromise safety and render the entire system non-compliant.

Technical Installation Procedure

1. Preliminary Verification

  • Analysis of the supporting structure: materials, condition, thicknesses, possible degradation.
  • Validation of operational conditions defined during design.
  • Verification of geometric compatibility and access to the installation area.

2. Mechanical Installation of Devices

Installation must ensure:

  • correct horizontal and vertical positioning of devices;
  • controlled tightening in accordance with manufacturer-specified torque values;
  • use of certified fixings suitable for the supporting structure;
  • continuity and alignment of flexible or rigid elements (lifelines, rails, tracks);
  • absence of structural or service-system interferences.

3. Installation Inspection

The installer verifies:

  • integrity and quality of assembly;
  • absence of defects, mechanical play, torsion, or unintended stresses;
  • full compliance with design documentation.

4. Declaration of Correct Installation

Issuing the declaration:

  • certifies compliance of the installation with UNI 11560:2022;
  • integrates the technical file of the fall protection system;
  • constitutes mandatory documentation for commissioning and subsequent inspections.
