Description

As forestry environments change yearly, management risk is important for logging contractors’stable management. In this study, we identified and evaluated the risks from the viewpoint of risk management for logging contractors. Risks were divided into five categories and further subdivided into nine categories. A questionnaire survey was conducted with authorized contractors in Miyazaki, Oita, and Kumamoto Prefectures to determine the frequency of occurrence and the degree of influence of the specific nine risks. It revealed that “accidental death” has a low frequency of occurrence but a high degree of influence on management, “unsecured worksites” has a low frequency and a moderate degree of influence, and “machine failure” has a high frequency but a low degree of influence. Other risks had a moderate frequency of occurrence and degree of influence. It can be deduced that the influence on management can be reduced by preventing the occurrence of “accidental death” and suppressing the occurrence of “machinefailures”. It is assumed that the risk of “unsecured worksites” has already been suppressed because the work of the contractors stops when it occurs. For the other six risks, risk treatment needs to be taken into account for “internal risks” and “external risks” that the contractors can control or not.
