PATH: A work sampling-based approach to ergonomic job analysis for construction and other non-repetitive work
A high prevalence and incidence of work-related muscoskeletal disorders have been reported in construction work. Unlike industrial production-line activity, construction work, as well as work in many other occupations (e.g. agriculture, mining), is non-repetitive in nature; job tasks are non-cyclic, or consist of long or irregular cycles. PATH (Posture, Activity, Tools and Handling), a work sampling-based approach, was developed to characterize the ergonomic hazards of construction and other non-repetitive work. The posture codes in the PATH method are based on the Ovako Work Posture Analysis System (OWAS), with other codes included for describing worker activity, tool use, loads handled and grasp type. For heavy highway construction, observations are stratified by construction stage and operation, using a taxonomy developed specifically for this purpose. Oberservers can code the physical characteristics of the job reliably after 30 h of training. A pilot study of six construction laborers during four road construction operations suggest that laborers spend large proportions of time in non-neutral trunk postures and spend approximately 20 % of their time performing manual material handling tasks. These results demonstrate how the PATH method can be used to identify specific construction operations and tasks that are ergonomically hazardous.
