Analysis and improvement of work postures in the building industry: application of the computerised OWAS method.
Awkward work posture is associated with the development of musculo-skeletal disorders. Previous workplace investigations in new building construction have shown that physical work affects workers' health in 46% of jobs. There is, however, a need for detailed analysis of jobs having physical workload and ergonomics problems. OWAS (Ovako Working Posture Analysing System) is a simple observation method for postural analysis, but there has been no study of its use in the building construction industry. The work described here examined (a) the use of the OWAS method to analyse work postures in building construction, (b) the development of a portable computer system for the OWAS method, (c) improvement of work postures identified as poor, and (d) use of the results as part of the ergonomics training programme of the company. Suggestions for work redesign measures are given.
