Tests of ABSORBICA lanyards in a fall over an edge
Basic Techniques
Depending on anchor position, the lanyard can rub on an edge in a fall. WARNING: assess the condition of any edges you may encounter in the field (sharpness and/or presence of burrs) and change the configuration to avoid exposing your lanyard to rubbing on an edge.
Warning
- Carefully read the Instructions for Use referenced in this Tech Tip before reading the Tech Tip itself. You must have read and understood the Instructions for Use to understand this supplementary information.
- Performing these techniques requires specific training. Work with a professional to confirm your ability to perform these techniques safely and independently before attempting them unsupervised.
- We provide examples of techniques related to your activity. Other techniques not described here may also exist.
The strength of ABSORBICA-I and Y lanyards is based on an existing standard: the EN 355 standard provides additional tests for this situation (PPE-R/11.074).
ABSORBICA-I and Y lanyards, both webbing and rope versions, meet the requirements of these tests.
Test of a straight fall over an edge
Mass 140 kg.
Drop height: 2 m.
Lanyard rubbing on a metal edge 0.5 mm in radius.
Requirement: the lanyard must not be severed.
Test of a pendulum fall over an edge
Mass 140 kg.
Drop height: 2 m.
Offset of 1.5 m to the side before the fall.
Requirement: the lanyard must not be severed.
Note: as with most laboratory tests, the chosen scenario is very harsh and not representative of a real work situation (for these tests, the lanyard was extended beyond the normal length). WARNING: observe the usage conditions for ABSORBICA lanyards as specified in the Instructions for Use.
