Fall arrest harness: standard, attachment points and size to choose

For work at height the fall arrest harness must comply with EN 361: this is the standard for the harness that holds the body in the event of a fall. If you also need to position yourself at the work, for example on a sloping roof or at a pole, look for a version with a work positioning belt to EN 358; to stay suspended for a long time or to work seated you need a seat harness to EN 813. Then choose size, attachment points and comfort according to the shifts you will be working.

The types

• Basic fall arrest harness: shoulder straps and leg loops with a dorsal attachment point, to EN 361. It is for people who work with a fall arrest system but do not need to hang for long periods.
• Harness with work positioning belt: it has a waist belt and side attachment points, for working supported or in tension (EN 358). Some models carry dual EN 361 and EN 358 certification.
• Harness with seat: it also has a seat or a padded belt for suspension work, such as the Avao SIT Fast by Petzl.
• Comfort harnesses: models such as the Astro or the Newton Fast are designed for everyday work at height.
• Kits and spare parts: the collection also includes complete protection kits, work positioning belts, seats, loops, covers and spare screws.

How to choose by job

The features to look at

Standards. On the data sheets you will find EN 361 (fall arrest), EN 358 (work positioning), EN 813 (sit harness), EN 1497 (rescue) and, on some models, EN 1149 (antistatic). In the kits you will also find EN 362 for connectors, EN 355 for energy absorbers and EN 354 for lanyards.

Sizes. From XS to XXXL: the most common combinations are S-M and L-XXL, or a universal size. Try the harness on over the clothes you will be wearing.

Weight. It ranges from models of about 500 g to over 2 kg for those with a belt and padding. Over an eight-hour working day you feel the weight. A few models state a maximum load of 140 kg.

Material. Polyester or polyamide webbing, aluminium or steel buckles. Aluminium buckles weigh less.

Version. Some models are offered in a European and an international version: check that it is the one required by your site.

Warranty. Many models state 3 years.

A harness is a piece of personal protective equipment: it must be chosen for the person who wears it and for the use they will make of it, and it must not be passed from one operator to another without adjusting it again. If the work also involves rescuing a person in difficulty, ask your safety manager which requirements apply.

Common mistakes

• Choosing on price or weight alone. First you need the right standard for the work you do.
• Taking the wrong size. If it is too loose you can slip out of it, if it is too tight it restricts movement.
• Using the work positioning belt as fall arrest. It is for positioning, not for stopping a fall.
• Not checking before use. Webbing, stitching and buckles must be inspected every time.
• Continuing to use a harness after a fall. It must be taken out of service.

Frequently asked questions

What is the difference between EN 361 and EN 358?

EN 361 covers the fall arrest harness, which holds the body if you fall. EN 358 covers the work positioning belt, for working supported without falling.

Where should it be attached?

To the designated attachment point, usually the dorsal one between the shoulder blades, with a lanyard and energy absorber or a self-retracting device, connected to a suitable anchor point.

How do I put it on?

Step into the leg loops and pull on the shoulder straps, fasten the buckles and adjust so that it fits snugly without constricting.

When should it be replaced?

After a fall, if the webbing or stitching is damaged, or according to the manufacturer's instructions. If in doubt, have it checked by a competent person.
