— What surface do you have?
Lifelines by Surface and Use
The system is not chosen from a catalog; it is chosen by what is beneath the anchor. The same line, on two different substrates, requires two different fastenings.
Industrial roofs and rooftops
Trapezoidal metal sheet, sandwich panel, deck roof, tile, slate, or fiber cement: each substrate requires its own fastening and load distribution beneath the finish.
Buildings and historic heritage
Housing associations, offices, hotels, and distinctive buildings where the installation must coexist with the facade, the property, and, in many cases, low visual impact requirements.
Towers, industry, and confined spaces
Wind turbine towers, telecommunications, photovoltaic plants, logistics buildings, and confined spaces: long climbs where the design must also allow for rescue.

What People Ask Us Most
About Lifelines
What Is a Lifeline and What Is It Used For?
It is a continuous anchor system (steel cable, rigid rail, or rope) installed on a surface or along a climb, to which the worker connects by means of a harness and lanyard. It serves to arrest a fall and limit the force transmitted to the body and the structure. It does not prevent slips or trips: what it does is stop the fall before it becomes a free fall. It is installed for work at height where perimeter collective protection is not feasible, or as a complement to it.
What Is a Certified Lifeline?
It is one whose components have been designed and tested in accordance with the applicable standard (UNE-EN 795 for anchor devices, UNE-EN 353 for vertical guided type fall arresters) and that comes with a declaration of conformity and an installation and user manual. It is worth distinguishing between declaring conformity and proving it: the latter requires a test report from an independent laboratory. The system is certified as a whole, not piece by piece, which is why components from different manufacturers cannot be mixed without invalidating the test backing.
What Is a Roof Lifeline?
It is the system installed on an industrial or building roof to allow the worker to move across the work plane with a permanent connection. It is normally horizontal, with cable tensioned between posts and intermediate continuous-pass anchors. Its design depends on the substrate (trapezoidal metal sheet, sandwich panel, deck, concrete, fiber cement) because each surface requires a different fastening and load distribution. The critical issue on a roof is the clearance height available below the plane: it determines whether the cable can work or whether a rigid rail is needed.
When is a lifeline mandatory?
The regulations do not require you to install a specific lifeline: they require protection against the risk of falls from height and establish an order of priority. Collective protection (guardrails, netting…) is considered first, and only when it is not technically feasible or proves insufficient is personal protection used, which is where the lifeline comes in. In practice, the requirement arises when there is a work or access area with a risk of falling to a lower level and the perimeter cannot be protected. That assessment belongs to the project and the activity’s risk assessment, not to the manufacturer’s catalog.
What Is a Lifeline on a Pitched Roof?
It is the system installed on a sloped roof (tile, slate, metal sheet) to allow safe access and movement during maintenance. What makes it special is the anchoring: it must reach the load-bearing structure beneath the finish (purlin, rafter, or slab) without compromising the roof’s watertightness. The slope adds a variable to the calculation, because it changes the fall trajectory and the load reaching the anchor. It is never anchored to the finishing material.
How Much Does a Lifeline Cost?
The price is not calculated per linear meter, even though that is the unit it is usually requested in. It varies according to the number of anchors, the type of substrate where it will be installed, the supporting element, and the number of simultaneous users.
Types of Lifelines by Project
The classification is not academic. Each axis (direction of travel, permanence of the anchor, rigidity of the line) changes the applicable standard, the fall distance calculation, and the final price.
Horizontal
They allow lateral movement across the work plane. Steel cable tensioned between posts, with intermediate continuous-pass anchors so the worker can travel the whole run without disconnecting. This is the most common configuration on industrial roofs. The horizontal lifeline is governed by UNE-EN 795 in its type C.
Vertical
They protect the climb, which is where the worker is most exposed: both hands occupied and free fall from the first rung. The vertical lifeline runs along the length of a fixed ladder or a tower, with a guided device that moves up with the user and locks in the event of a fall. Regulatory framework: UNE-EN 353.
Permanent
A stable installation, permanently anchored to the structure and sized during the design phase. It is the right choice when access to the risk area is recurring: HVAC maintenance, exhaust systems, photovoltaics, skylight inspection. The permanent lifeline requires a logbook and annual inspection, and in return it is ready the day someone opens the hatch.
Temporary
They are set up for a specific job and removed when it is finished. Transportable anchors on existing structural points, normally in a quick-to-install textile configuration. The temporary lifeline covers construction, assembly, and occasional maintenance, and is governed by UNE-EN 795 type B.
Rigid
When the clearance height below the work plane is limited, cable is not suitable: under load it deflects, and that sag adds to the fall distance. The rigid aluminum rail (UNE-EN 795 type D for horizontal, UNE-EN 353-1 for vertical) deflects practically not at all. It is the solution in low-clearance buildings, mezzanines, and technical walkways, and also when the worker will be working in suspension.
Retractable
The self-retracting fall arrester is not a lifeline in the strict sense, although on job sites it is often called one. It is a device that anchors at a fixed point and automatically retracts the cable, locking on sudden acceleration. It handles descent, suspension, and occasional vertical access scenarios, but it does not cover long travel across a roof or a climb up a ladder. It coexists with the lifeline; it does not replace it.
Solutions and Sectors Where to Install a Lifeline
There are environments where the climb or the access defines the whole system:
- Lifeline for wind turbine towers: long climbs, exposure to fatigue, and intensive duty cycles. Here the rail beats the cable in almost every case.
- Lifeline for telecommunications towers: slender structures, repeated climbs, and transfer at the top, which is where a good share of incidents are concentrated.
- Lifeline for confined spaces: vertical access with the added risk of rescue. The system must not only arrest a fall: it must allow the worker to be extracted.
- Rooftop photovoltaic installations, where travel between modules requires continuous movement.
- Logistics buildings, shopping centers, and industrial plants, for access to HVAC and exhaust equipment.
- Civil works: bridges, walkways, and steel structures during assembly.
Lifeline: Personal Protection, Not Collective
It is worth clarifying this because it is a frequent error in risk assessment: a lifeline is not collective protection. It is part of a personal protection system: it only works if the worker wears a harness and a lanyard with an energy absorber and connects correctly. If they do not clip in, the system does not work.
That is why the hierarchy of controls puts collective protection first, since it protects everyone who gains access without requiring any action from the user. The lifeline comes in when that protection is not feasible, or as a complement where the work is done outside the protected perimeter.
In addition, we must keep in mind that the lifeline does not prevent the fall; what it does is stop it before it reaches the ground and limit the force transmitted to the body and the structure. That is why it is important to calculate the distance to the ground correctly, to avoid increasing the risk. ç
