Fall arrest

A personal fall arrest protection device includes several crucial elements and a set of standards :


• Body holding device (with one or more hooking points)
• Link between that device and an anchoring point
• Anchor device (anchoring point and structural anchor)

 

Standards

> The safety harness,

body holding system designed to prevent falls, attached directly to the user. This system can include various parts : straps, buckles, etc...
A harness includes at least one anchoring point (or attaching point) providing a link with a lanyard. This part is covered by standard EN361:
« Personal protective equipment against from falls from a height: full body harnesses ».
The harness may also include a belt (body holding device around the waist). The belts are covered by standard EN358:
Personal protective equipment for work positioning and prevention of falls from a height : «Belts for work positioning and restraint and work positioning lanyards ». The belts can also be used as work positioning and retention belts, when hooked up to a lanyard. (in this case, the gear does not fulfil the fall arrest function)


> Anti - fall link
(connecting element)
It is the link between the person – the harness – and the anchoring point). It is a lanyard that is typically made from rope, synthetic fibber, metal wire, strap or chain. Maximum length = 2 meters. This part is covered by standard EN354 «Personal protective equipment against falls from a height: Lanyards».
These elements can include an energy absorber ; the energy absorber helps absorb the impact of a fall. This element is covered by standard EN355 « Personal protective equipment against falls from a height: Energy absorbers ». The absorber is made up of a strap folded into a package. In the event of an impact, the package is torn open and the strap unfolds, thereby reducing the braking force to a non harmful level. The anti-fall link is equipped with a connector that links to both: to the harness (fastening point) and to the anchoring point. The connectors can be made directly with the lanyard and/or the energy absorber or sold separately and fitted on using a karabiner

The connectors are covered by standard EN362 « Personal protective equipment against falls from a height : Connectors ». Iron or steel connectors should be protected against corrosion.

> A anchor device
Structural anchor - anchor device - anchoring point - PPE
Structural anchor - PPE

The anchoring device is covered by standard EN795 « Protection equipment against falls from a heights
- Anchor devices – Requirements and testing ».

Various classes are defined in the standard according to the anchoring type.
Class A1  Structural anchors designed to be secured to vertical, horizontal and inclined surfaces - PPE
Class A2  Structural anchors designed to be secured to inclined roofs - PPE
Class B     Transportable temporary anchor devices - PPE
Class C    Anchor devices employing horizontal flexible lines - non PPE
Class D    Anchor devices employing horizontal rigid anchor rails - PPE
Class E    Dead weight anchors for use on horizontal surfaces - PPE
There can be safeguard supports between the anchors :
• anchor rail connectable to PPE
• flexible anchor line connectable to PPE
