In residential constructions, falls are the most serious causes of all fatal injuries. The elevation of these falls are relatively lower in almost all cases. Although there are rules for the usage of proper fall arrest systems (FAS) during the construction works, these rules are not properly enforced in residential roofing. In this research by using two types of FASs across two scaled models, different performance times (don time, doff time, tar paper setting time and shingle setting time) were measured. Two scaled models were built in indoor and outdoor location to see whether change of context affects the performance times. Data were analyzed by using SAS 9.4™.
