This study is a follow-up of the recommendations of the first phase, which after an analysis of the construction/building materials sector, selected three products as having the greatest opportunity for growth. The products identified were natural stone, fired clay products and recycled plastics products. Download Free PDF.Background and objectives The prevalence of occupational injuries among blue-collar workers is higher in the stone-crushing industries due to high-risk and iterant nature of the work. These occupational injuries, in turn, caused workers’ ill health, as well as death, which eventually diminish the gross domestic product. We aimed at assessing the Occupational injuries and risk assessment among stone crushing
