ABSTRACT
The International Organization for Standardization (ISO) published a new Technical Specification (TS), ISO/TS 20646-1 "Ergonomic procedures for the improvement of local muscular workloads (LMWL)--Part 1: Guidelines for reducing local muscular workloads" in 2004. However, little is known about whether the ISO/TS is really effective in taking action to improve the work conditions in real workplaces. This paper discussed the impact of preventive activities planned and carried out according to the ISO/TS in 17 enterprises. Results indicated that 61 improvements (96%) had already been implemented (63%) or in progress (33%) within 6 months of the start of the activities. Besides the initial improvements, new improvements added within one year reached 84 cases and 10 cases were in progress in 15 enterprises. Comprehensive risk analysis, which consisted of a series of applications of action oriented checklist and group discussions, contributed to the detection of widely diversified risks in each local workplace, and this seems to lead to sustainable activities for prevention of WMSDs. These results suggest that the ISO/TS 20646-1 help managers and workers to control multiple work-related musculoskeletal disorder (WMSD) risks on their own initiative and promote sustainable activities.

An intervention based on the methodology developed by the International Labour Office, the Work Improvement in Small Enterprises (WISE) was carried out to improve work condition of small-scale enterprises and the informal sector in the Philippines, Thailand and Japan. Through the evaluation of the efficacy of the approaches based on participatory methodology, it is concluded that the method is an efficient measure to improve work condition in small workplaces. It is also pointed out that the activities of supporting experts such as introduction of the methodology and evaluation of the activity are necessary. The important roles of the experts are 1) to encourage managers and workers to sustain the activities for work improvement, 2) to analyse the effectiveness and problems of the implemented improvements, 3) to give appropriate suggestions for the further improvement, and 4) to get materials for demonstrating the effectiveness of WISE activities on improving work conditions and productivity to other managers and workers who have not participated in the activity.
