The objective of this study is to help recognise the factors that cause occupational accidents in logistics in order to improve occupational safety. This study is limited to materials transported by trucks on roads, and materials transferred at construction sites. Study shows that even though there are a lot of occupational accidents in material transfers, there are several things that can be done in order to prevent such accidents. The employer bears the main responsibility for preventing accidents, but still there are several things that workers can do. It is worthwhile that employers, the occupational health service and workers recognise the risks caused by material transfers so they can co-operate in improving safer working conditions.
