Abstract
Working environment at fishery ports and harbors during the winter in cold, windy regions such as Hokkaido, is very severe for workers. Therefore snow and wind shelters have been constructed in Hokkaido. We analyzed the results of questionnaire survey to evaluate working environment before and after the construction of the shelters. We found that the work load has been eased or the work efficiency has been increased after the construction of the shelter. We also performed on-site observation at a shelter of Otsu fishery port constructed in Dec. 2007 to evaluate the performance of wind reduction due to the shelter. We did a trial calculation the effect of the improvement of the work environment by the shelter on that of the work efficiency.
