Fall-arrest system have been widely applied to provide a safe stop during fall incidents for occupationalactivities. This research object to evaluate the energy capacity of fall arrest shock energy absorber lanyard in relation tothe used super fiber. In this work, shock energy absorber lanyard was prepared using high tenacity PET, high tenacityPET/P-aramid and high tenacity PET/UHMWPE, respectively. Dynamic load and static load tests based on the Korea fallprotection equipment standard(Korea Occupational Safety & Health Agency standard 2013-13) were conducted. Maximumarrest force by dynamic load test of shock energy absorber showed below 6,000N. Also, static strength by static load testof lanyard and rope remains 15,000N and 22,000N for 1 min.
