Construction safety nets – collective fall protection to EN 1263
Working at height in commercial building construction, industrial projects, and steel structure assembly requires strict adherence to safe working conditions. AITANA SAFETY supplies certified construction safety nets manufactured in full compliance with EN 1263-1 and EN 1263-2. As temporary collective protection (CPE), our safety netting construction systems serve as the primary line of defense against fall hazards, safeguarding worker health while protecting the entire job site. A fall safety net is the only fall arrest solution that functions completely on its own. On this page, we explain when roof safety netting is the right technical solution, which configurations are specified under EN 1263 standard, and how to select the optimal system for your specific construction tasks.

Why a safety net is a collective protection (and Lanyards are not)
The distinction between collective and personal protection is not merely formal—it is practical and comes down to one single question: what must the worker do for the protection system to work? With personal protective equipment (PPE) — such as harnesses, lanyards and anchor points — the worker must take multiple active steps. They must have the equipment, don it correctly, locate a suitable anchor point, tie off, and remain continuously attached throughout their shift, even when moving a few meters away for “just a moment.” Every single step creates an opportunity for human error or omission. With a safety net, the worker does not need to do anything. The protection is already in place, it covers the entire working area, and protects everyone equally: the rebar team, the site manager stepping onto the floor slab for a quick inspection, or a subcontractor on site for just two hours without prior specialized PPE training.
This fundamental difference creates tangible advantages visible in both project budgeting and scheduling:
- Large surface area coverage: Does not limit the number of workers. A single safety net installation easily secures an entire hall bay or open floor slab, regardless of how many workers are active—whereas a Class A anchor point typically supports only one user at a time.
- Freedom of movement and efficiency: Does not restrict worker mobility. Personnel working above a net-protected zone do not need to constantly attach and detach lanyards from anchors, significantly accelerating work pace and improving ergonomics.
- No user certification required: Workers active above a safety net do not require specialized training on operating personal gear that they are not wearing.
- Falling object protection: Safety netting catches falling tools and small debris, which no personal harness system can accomplish.
- Zero risk of human error: A safety net system operates continuously and passively—protecting anyone who enters the hazard zone regardless of their training level.
Under EU Framework Directive 89/391/EEC and national health and safety regulations for construction work, employers have an overriding legal obligation to give priority to Collective Protection Equipment (CPE) over Personal Protective Equipment (PPE, such as harnesses and lanyards). In practice, anchor points and lifeline systems should only be specified where collective protection cannot be physically installed.
When building safety nets are the right choice
A safety net is not the answer to every situation. It is most effective when three specific conditions are met simultaneously:
- The work is temporary. Nets are installed for the duration of construction activities—structure erection, roof decking, or floor slab casting. Permanent roof guardrails, not construction safety nets, should be used for long-term building maintenance.
- Structural attachment points exist: The support structure must be capable of bearing the load forces transmitted through the net anchorages. EN 1263-2 standard specifies characteristic anchor loads 4kN and 6kN per anchor point for System S under a 6 m drop height—a requirement that must be verified during engineering planning.
- Fall clearance exists below: A construction safety net arrests a fall through elastic deflection, meaning adequate free space must remain underneath. The larger the net span, the greater the dynamic deflection—a factor that usually determines whether a net system can be deployed.
Two crucial parameters to know before requesting a quote: the maximum allowable fall height onto a construction safety netting cannot exceed 6.0 meters, and the catch width—how far the net must extend beyond the working edge—ranges from 2.0 to 3.0 meters depending on the fall height. Both parameters are governed by EN 1263-2 standard and directly shape the safety design.
Four safety nets systems under EN 1263 standard – which one to choose?
The EN 1263 standard is divided into two parts: Part 1 defines safety requirements and test methods for the net itself, while Part 2 governs installation positioning limits. Part 2 introduces four distinct systems, designated by the letters S, T, V, and U. They do not differ in net material, but in how the net is fixed—which dictates where each system can be deployed on a construction site.
| System | How it is fixed | Typical use | When to choose it |
|---|---|---|---|
| System S (horizontal, on a rope) | border rope fixed directly to the structure | hall roofs, trapezoidal sheet, openings in slabs, bridges | when there is something to fix the rope to and room for a full-format net |
| System T (on fixed brackets) | net on horizontal brackets fixed to the slab of the floor below | steel fixing and formwork at the building edge | when the concrete of the floor below has reached the required strength |
| System V (on an adjustable bracket) | net on a jib with an adjustable angle | the same as system T, on buildings with awkward geometry | when there is no crane or the building is complicated |
| System U (vertical, on a frame) | net tensioned vertically on a supporting structure | guardrail infill, warehouse racking | when the point is to prevent the fall, not to arrest it |
The fall height onto the net in systems S, T and V must not exceed 6.0 m — the detailed installation conditions are set by EN 1263-2.
System S – when there is something to fix the netting rope to (horizontal safety nets)
System S represents the simplest and most cost-effective configuration: fall arrest is provided directly by the net without heavy secondary steelwork. System S horizontal construction netting are stretched directly below the working plane. They are widely used during hall roof decking, trapezoidal sheet installation, steel frame erection, and floor void protection. However, System S requires full-format dimensions — EN 1263-2 standard specifies a minimum area and side length for this system. Read full technical details in our section on S system safety nets.
System T – Horizontal Console Netting for Slab Edges
System T consists of a net mounted on horizontal steel console arms anchored to the floor slab or facade of a lower level where concrete has achieved required curing strength. It creates a horizontal protective fan extending beyond the building perimeter—ideal for rebar tying and edge formwork. Learn more about requirements and testing for System T safety nets.
System V – the same job as system T with less equipment
System V serves a similar edge protection purpose as System T, but on a bracket with an adjustable angle. It is often the preferred choice for complex building geometries or where mobile crane access is restricted. Explore details on V type safety netting.
System U – the only one that prevents a fall instead of arresting it – vertical protective netting
A net tensioned vertically on a supporting frame structure. Unlike Systems S, T, and V, it does not catch a falling person—it prevents them from stepping over the edge. System U is widely used as scaffolding infill, side protection for temporary guardrails and on warehouse racking.
Specialized solutions beyond EN 1263 standard
At AITANA SAFETY, we engineer and supply custom safety solutions tailored to unique construction site requirements. Not every job site hazard fits into the four standard EN 1263 systems. Two specialized systems in our range operate outside EN 1263 and rely on alternative standards:
RAND PLUS System – Edge Protection
A perimeter netting system mounted on steel brackets creating a complete edge barrier. Certified under EN 13374 standard as Class C (the standard governing temporary edge protection systems). We deploy RAND PLUS during steel hall roof assembly and for bridge and viaduct protection, simultaneously protecting workers above and traffic passing below.
RAND MATERIALS System – Debris & Material Containment
By combining a primary safety net with a fine-mesh debris lining (micro-mesh), we achieve effective protection against falling objects, catching tools, concrete rubble, and construction debris.
Neither RAND PLUS nor RAND MATERIALS should be confused with standard EN 1263 safety nets: they serve distinct functions and comply with different standards.
AITANA SAFETY – technical support and custom B2B Engineering
For over 10 years, we have supplied certified construction safety nets across projects all around Europe— from single floor voids to major bridge structures. Our systems are tested by independent accredited laboratories in accordance with European standards, and every delivery is supplied as a complete, fully tested system: net, border ropes, tie ropes, and couplers.
At AITANA SAFETY, we go far beyond supplying equipment. We deliver comprehensive engineering support at every stage of construction. For complex building geometries (such as irregular bridge spans or non-standard hall columns), our engineering team designs and manufacture custom mounting brackets, anchors, and mounting arms. We assist site managers and HSE teams in selecting Collective Protection Equipment (CPE) that optimizes both safety compliance and operational efficiency.
In the seven-step ladder for choosing protective measures, the safety net appears twice: rigged at working level it shortens the fall distance, rigged lower down it limits the consequences of the fall. It is the only measure that appears on that ladder twice — we set out the seven-step ladder for choosing fall protection in full in our main guide.
FAQ – frequently asked questions about construction safety nets
What is the difference between a safety net and a general protective net?
“Safety net” is a precise technical term under EN 1263-1 standard referring exclusively to nets tested and certified to catch a falling person. “Protection netting” is a broad commercial term that includes non-certified netting used for cargo, sports, warehousing, or agriculture. When purchasing OHS equipment, ensure the net is explicitly certified to EN 1263-1 standard; general “protective nets” do not meet fall arrest requirements.
Up to what height can safety nets be deployed?
The constraint is not the building height, but the allowable fall height—the vertical distance between the working level and the net. Under EN 1263-2 standard, the fall height Hi onto a safety net must not exceed 6.0 m. Within 2.0 m of the net border, the allowable fall height decreases to 3.0 m due to lower edge elasticity. Nets should always be hung as close below the working level as possible to minimize fall distance and net deflection.
How do I check whether a safety net is certified?
Check for the permanent identification label and sample test meshes. A certified EN 1263-1 net features a permanently attached label stating manufacturer details, net system, manufacture date, and unique serial number. It also includes removable, barcoded “test meshes” that are sent for annual UV degradation testing. A net lacking a label and test meshes is not a certified safety net under European law. Whatever it looks like.
How much fall clearance is required underneath a safety net?
Sufficient fall clearance must be maintained so that a falling person’s dynamic deflection does not cause them to strike the ground or underlying obstacles. Net deflection depends on span size and fall height, and can reach several meters on large spans. Minimum clearance requirements are calculated during the safety design phase according to EN 1263-2 deflection curves.
Can safety nets be reused across multiple projects?
Yes, multi-project reusability is a key economic benefit of safety netting. Reuse requires pre-installation visual inspections and annual laboratory testing of the test mesh to verify that UV degradation has not reduced energy absorption below minimum thresholds. Under EN 1263 standard, any net that has arrested a fall must be immediately removed from service until inspected and re-certified by a competent person.
What is the difference between knotted and knotless netting?
Knotless nets, made from high-tenacity polypropylene, are lighter, less prone to abrasion where the fibres cross, and more flexible in absorbing the energy of a fall than traditional knotted nets. Knotless safety nets (manufactured from High-Tenacity HT Polypropylene) are lighter, exhibit significantly lower fiber abrasion at mesh intersections, and absorb impact energy more elastically than traditional knotted nylon nets.
