Fall Arrest Harness: How to Choose the Right One

Written by the SASSI technical team · Last updated: June 18, 2026 · Reading time ~13 min

The fall arrest harness is the only personal protective equipment approved — by standard EN 361 — to connect an operator's body to a fall arrest system. It is the cornerstone of all work at height: it is what, in the event of a fall, distributes the arrest force over the body areas capable of withstanding it and keeps the operator upright. But you still need to choose the right model. This guide details harness types, attachment points, materials, adjustment, and the range suitable for each trade.

1. Why only a full harness is approved

Only a full harness, with shoulder straps and leg loops, is recognized as fall arrest equipment. A simple belt is not.

The reason is physiological. When arresting a fall, the body undergoes abrupt deceleration. A belt alone would concentrate all this force on the abdomen and lumbar spine — with a risk of serious injury, or even head-down inversion. A full harness, on the other hand, distributes the effort over the thighs, pelvis, torso, and shoulders, and its dorsal (or sternal) point keeps the operator upright, in a posture where they can await rescue. This is precisely what standard EN 361 verifies: body posture and load distribution after a fall.

A harness consists of webbing (shoulder straps and leg loops), adjustment buckles, a dorsal plate, attachment points, and, depending on the model, a work positioning belt, comfort reinforcements, and a "bavaroise" (the wide bib of webbing that distributes support in the back).

2. The three types of harnesses

There are three families of harnesses depending on the desired function: fall arrest only, fall arrest with work positioning, and suspension seat harness.

To remember: these standards are cumulative, they do not replace each other. A work positioning harness EN 358 without EN 361 does not protect against a fall. For any situation where a fall is possible, EN 361 is mandatory.

3. Attachment points: 1, 2, 4 or 5

The number and position of attachment points determine the possible uses of the harness. Only the dorsal and sternal points are used for fall arrest.

4. Materials and design: what really makes a difference

Harness webbing is made of polyester or polyamide; the choice influences behaviour to humidity, UV, and impact.

• Polyester: stable over time, little sensitive to humidity and UV, low elongation. It is the material for versatile fall arrest harnesses — construction, scaffolding, aerial work platforms.
• Polyamide: more elastic, it better absorbs dynamic stresses. It is preferred for work positioning and suspension harnesses (arboriculture, pole work), where comfort during prolonged support matters.

Beyond the webbing, several elements make a difference in use:

• The dorsal plate positions the attachment point between the shoulder blades and holds the harness in place.
• The bavaroise and foam reinforcements (shoulders, thighs, back) distribute support and reduce fatigue during long days.
• The work positioning belt, wide and sometimes 180° rotatable (as on REF. 464), facilitates lateral work and suspension.
• The dorsal extender strap makes the dorsal point more accessible for self-attachment.

Adjustment buckles

The adjustment system determines the speed of donning and the maintenance of adjustment over time:

• RAPCO buckles: quick adjustment by notching, without fully loosening each time it is put on. Very common on leg loops.
• Automatic buckles: passage and tightening in one movement, ideal for shoulder straps that are often adjusted (Pro range, e.g., REF. 450 RCE).
• Progressive tightening buckles: fine adjustment of the ventral belt.

5. How to choose your fall arrest harness

Ask yourself four questions: what working posture, how many points, what comfort for what duration, and what maximum load?

1. What posture? If you are only arresting a potential fall (roof, scaffolding), an EN 361 fall arrest is sufficient. If you are working supported (pole, facade), you need EN 358 work positioning. If you are working suspended (arboriculture, rope), add EN 813.
2. How many points? 1 point for the essential, 2 points for versatility, 4 points for work positioning, 5 points for suspension.
3. What comfort? The longer the wearing time, the more crucial foam reinforcements, wide bavaroise, and elastic shoulder straps become. Accessories such as the positioning vest REF. 96 or the shoulder reinforcement REF. 97 adapt to most models.
4. What load? Check the maximum working load (user + tools). Several SASSI harnesses are approved up to 150 kg.

6. The SASSI harness range: Essential, Pro, Expert

SASSI structures its range into three levels — Essential, Pro, and Expert — to cover all needs, from occasional construction sites to specialized interventions.

7. The right harness for your trade

To each trade its posture, therefore its harness. Here are the direct correspondences.

• Mason, facade plasterer, roofer, scaffolder: 1 or 2-point fall arrest — 460 bis, 453N, 450 RCE.
• Carpenter, civil engineering: 2 or 3-point fall arrest for easy connection during progression — 450 RCE, 409.
• Roofer, photovoltaic installer: 2-point fall arrest + mobile fall arrester on rope — 450 RCE.
• Aerial work platform (MEWP), crane operator: 2-point fall arrest with short lanyard — 450 RCE.
• Wind turbine technician: multi-point harness with work positioning/suspension — 464, 474, 477.
• Arborist: EN 813 suspension seat harness — 464, 474.
• Pylon worker, pole work: work positioning + fall arrest — 464, 474.
• Window cleaner, rope access technician, water tower, sanitation: 4 or 5-point high comfort — 474, 477.

8. How to properly don and adjust your harness

A poorly adjusted harness loses a large part of its effectiveness and becomes uncomfortable. Adjustment must be checked each time it is put on.

1. Grab the harness by the dorsal plate and untangle the webbing before putting it on.
2. Pass the shoulder straps like a jacket, then buckle the leg loops without crossing them.
3. Adjust the leg loops: you should be able to pass a flat hand, no more.
4. Adjust the shoulder straps so that the dorsal plate is positioned between the shoulder blades.
5. Check the sternal point: at chest height, neither too high (neck discomfort) nor too low.
6. Ensure no webbing is twisted and that surpluses are tucked into the keepers.

A well-adjusted harness fits without sagging and allows full freedom of movement. If it sags or compresses, it is poorly adjusted — or it is not the right size.

9. Harness and rescue: a point too often overlooked

After a fall, remaining suspended in your harness is dangerous: this is harness syndrome. Rescue must be anticipated before ascending.

An immobile operator, suspended in their harness, experiences slowed venous return: harness syndrome (or suspension trauma) can lead to loss of consciousness in a few minutes. This is why all work at height must be accompanied by a rescue plan and a quick recovery method. Some harnesses include rescue points or straps (standard EN 1497 for rescue harnesses) facilitating hoisting or lowering the victim. In confined spaces, the harness is combined with a tripod and a rescue winch (EN 1496) to lift the operator without a second intervener having to descend.

10. Inspection, maintenance, and lifespan (EN 365)

A harness is visually inspected before each use and undergoes a thorough examination at least every 12 months by a competent person.

• Before each use: inspect webbing (cuts, burns, chemical attack, discoloration), stitching, buckles (deformation, corrosion), plate, and attachment points.
• At least every 12 months: documented periodic examination (PPE lifetime record), in accordance with EN 365 and the manufacturer's instructions.
• Maintenance: clean with lukewarm soapy water, dry in the shade away from any heat source, store away from UV and humidity.
• Immediate disposal after any fall arrest, or as soon as serious doubt arises.

11. SASSI versus Petzl, Tractel, Honeywell, Kratos, Néofeu

The fall arrest harness market brings together major manufacturers. SASSI stands out as a historic French harness maker, capable of both standard and custom solutions.

Each player has their preferred field: Petzl (suspension comfort and rope access), Tractel (industrial ranges and lifelines), Honeywell Miller and Kratos Safety (wide offering for industry and construction), Néofeu (French manufacturer, anchors and harnesses). All rely on the same EN 361 standard, a guarantee of interoperability within a fall arrest system.

SASSI's uniqueness lies in its original trade. The company was founded in 1920 with expertise as a saddler-harness maker: the harness is, literally, its founding profession. The acronym recalls this — S.A.S.S.I., Société d'Articles de Sécurité et de Sellerie Industrielle (Society of Safety Articles and Industrial Saddlery). Today, backed by a 100% French industrial group, SASSI internally masters webbing, technical stitching, and the metallurgy of its buckles and connectors, designs and manufactures its harnesses in France (with "Made in France" mentioned on several products), and produces custom harnesses — specific adjustments, load up to 150 kg, company branding. For the buyer, this means a contact person who genuinely manufactures what they sell, with the traceability and responsiveness of local production.

Frequently Asked Questions

How to choose your fall arrest harness?

Based on four criteria: working posture (fall arrest, work positioning, or suspension), number of attachment points (1, 2, 4, or 5), comfort adapted to wear duration, and maximum load (up to 150 kg). The harness must always comply with EN 361, supplemented by EN 358 (work positioning) and EN 813 (suspension) if needed.

What is the difference between a 1, 2, 4, and 5-point harness?

1 point (dorsal) = simple fall arrest; 2 points (+ sternal) = versatile fall arrest; 4 points (+ lateral and waist belt) = work positioning; 5 points (+ ventral) = suspension. Only the dorsal and sternal points are used for fall arrest.

EN 361 or EN 358 harness: what's the difference?

EN 361 certifies the harness for stopping a fall. EN 358 concerns work positioning (hands-free support) and does not protect against a fall. Both can be combined, but EN 358 never replaces EN 361.

Polyester or polyamide webbing?

Polyester (stable, less sensitive to humidity and UV) is used for versatile fall arrest harnesses; polyamide (more elastic) is preferred for work positioning and suspension. SASSI uses both depending on the model's intended use.

Which harness for a wind turbine technician?

A multi-point harness with work positioning, or even suspension: SASSI 464 (4 points, 180° rotating waist belt), 474 (EN 813 leg loops), or 477 (5 points), all up to 150 kg.

What is the lifespan of a harness?

It is indicated by the manufacturer and depends on use and storage. Separately, a harness is discarded after any fall arrest or at the slightest deterioration. Mandatory periodic inspection every 12 months (EN 365).

Are there harnesses up to 150 kg or custom-made harnesses?

Yes. References 453N and 464 are approved for up to 150 kg, and SASSI produces custom configurations (adjustments, company branding) thanks to its French manufacturing.

What is a RAPCO buckle?

A rapid adjustment system with teeth, on leg loops and shoulder straps, which allows the harness to be adjusted without completely loosening it each time it is put on. Other models use automatic or progressive tightening buckles.
