Hazards – Lanyards used for Fall Protection

It is common practice for a worker to wrap a lanyard around a structural steel section for protection against falling.  It was discovered during laboratory testing that 5/8-inch-wide (16 mm) 3-strand nylon lanyards lost up to 90% of their original strength when arresting a fall.  The test was performed according to CSA Standard Z259.1-M1976.  Similar tests on 7/8-inch-wide nylon web lanyards ended with no arrest at all.  In both cases the lanyards’ loss of strength was caused by cutting action of the edges of the I-beam.
