摘要：Abstract Small and medium-size enterprise accidents constitute a large proportion of the occupational health and safety accidents recorded in the construction industry. The methods used to tackle occupational health and safety issues in large enterprises do not work most of the time in the small and medium sized enterprises. Therefore a way of tackling occupational health and safety in these enterprises has to incorporate methods and tools specifically designed for them. This can be done by using a risk estimation tool specifically designed for small and medium sized enterprises. In this paper a literature survey supplemented by data collection is used to identify key factors which can be used in the occupational health and safety risk estimation tool. Three sources were used to identify factors by analyzing and comparing the data acquired. Consequently, 9 key factors were chosen in total from the three data sources and literature survey.
