WH SCOTT
Vertical and Horizontal Lifeline Systems
Design, supply and installation of vertical and horizontal lifeline systems, including flexible and rigid systems for permanent fall protection and safe access at height.
Lifeline Systems for Safe Access at Height
A lifeline system keeps a worker attached to the structure for a whole route — a roof edge, a gantry, a fixed ladder, the top of a tanker. Designed properly, the user clips on once at the access point and stays connected until they come down.
WH Scott surveys the structure, designs the system around it, installs it, certifies it and returns to re-inspect it. We are an approved centre and system installer for 3M, working with the SALA and Protecta wire and track ranges. We are also a lead supplier of Rothoblaas height safety equipment, covering the Rothoblaas fall protection range of cable and rail lifeline systems, vertical lifelines and anchor points. We cover the UK and Ireland from 14 depots under a certified ISO 9001 quality management system.
Horizontal or Vertical: Matching the System to the Route
Horizontal lifelines — wire or track
Horizontal systems run along the working route and let the user pass intermediate brackets without disconnecting. Wire (EN 795 Type C) is more economical over long spans and suits roof edges and open steelwork. Rigid track or rail (Type D) deflects far less under load, shortening the total fall distance — the right choice where clearance below the user is restricted, or where the route turns corners or passes obstructions a cable cannot follow. We install both from the 3M ranges and from Rothoblaas: PATROL modular cable lifelines for roofs, façades, wall-mounted and overhead runs, and H-RAIL rigid and flexible rail where the route is constrained.
Vertical lifelines — ladders, masts and climbs
Vertical systems protect the climb itself. A guided type fall arrester travels on a cable or rigid anchor line as the user ascends and locks if they fall; rail systems are covered by EN 353-1, cable systems by EN 353-2. Both retro-fit to fixed ladders on masts, towers, silos and chimneys. Rothoblaas VERTIGRIP is a standard option here for ladder and wall-mounted vertical lifelines, alongside the equivalent 3M systems. Where the ladder or its fixings will not carry the arrest load, we will tell you rather than fit a system to a structure that needs replacing first.
What Drives the Design
- Available fall clearance. Free fall, energy absorber deployment, line deflection and harness stretch all add up. In low-clearance environments it is arrest distance, not span, that dictates the system — usually where track replaces wire.
- Simultaneous users. EN 795 covers single-user anchor devices; systems rated for more than one person at a time are tested to CEN/TS 16415. Adding users to an existing system without re-checking the anchorage is a common fault.
- Structure and anchorage. Substrate, purlin spacing, roof build-up and end-anchor loads must be verified before anything is fixed. Where there is no suitable structural fixing, a counterweight system (Type E) may be the only option. Rothoblaas supplies tested supports and fastenings for each substrate — timber, concrete, steel, trapezoidal and standing seam metal, PVC, bituminous and ballasted flat roofs — including ballasted lifelines and Rothoblaas anchor points where the roof cannot be penetrated.
Where nothing off the shelf will fit, our custom height safety solutions team engineers the system around the structure.
Standards and Compliance in the UK and Ireland
In Great Britain the duties to plan the work, work down the hierarchy of control and inspect the equipment sit in the Work at Height Regulations 2005. In Ireland they sit in Part 4 of the General Application Regulations 2007 (S.I. No. 299 of 2007) — Regulation 109 on personal fall protection systems, 112 on fall arrest systems and 119, which requires inspection after installation and periodically thereafter. The HSA guide to Part 4 sets out how they are met in practice.
The same EN standards apply either side of the Irish Sea, published as BS EN in the UK and I.S. EN in Ireland: EN 795 for anchor devices, CEN/TS 16415 for multi-user systems, EN 365 for periodic examination. Permanently fixed anchor devices (Types A, C and D) are not classed as PPE and carry no PPE marking, so what evidences a system is its design and installation record rather than a label. BS 7883:2019 sets out what that record should contain. Rothoblaas designs, tests and certifies its own fall protection products and publishes the technical data, tested fastening details and installation instructions that record is built from.
Inspection, Recertification and Existing Systems
Installed systems should be examined by a competent person at least every 12 months, and more often where the manufacturer’s instructions or the environment require it — grit, salt, chemicals, UV or heat all shorten the interval. Any system that has arrested a fall comes out of service immediately; HSE guidance on inspecting fall arrest equipment applies the same principle to the harnesses, anchor points and self-retracting lifelines used with it.
We inspect, recertify, extend and modify systems installed by others. Where one cannot be recertified as it stands we will say so and set out what it would take to return it to use — missing original documentation is the most common finding on inherited systems. Recertification can run alongside your other statutory inspections so one visit covers the site.

Frequently Asked Questions
What is the difference between a horizontal and vertical lifeline system?
A horizontal lifeline runs across a structure, allowing lateral movement, while a vertical lifeline is typically installed on ladders or vertical access points to provide continuous fall protection during ascent and descent.
Can lifeline systems support multiple users at the same time?
Yes, systems can be engineered for multi-user capacity, depending on load ratings, anchorage design, and system specification.
Are lifeline systems suitable for low clearance environments?
Yes, systems can be specifically designed for low fall clearance scenarios, reducing arrest distances and improving safety in restricted spaces.
Are inspection and maintenance services available?
Yes. Ongoing inspection, testing, and maintenance services can be provided to help ensure systems remain safe, compliant, and fit for use throughout their operational life.
Can lifeline systems be installed on complex structures?
Yes, modern systems can navigate changes in direction, gradients, and obstacles while maintaining continuous user attachment.
Do I need a rescue plan as well as a system?
Yes, and it is the most commonly missed part. Someone suspended in a harness after a fall usually cannot self-rescue, and suspension trauma makes prompt recovery critical. We specify retrieval equipment alongside the arrest system rather than after it.
