The accident investigations from the archive of the Labour Office were searched and ongoing construction sites in North Cyprus were visited. Descriptive statistics were used to classify the full archival and inferential statistics were carried out to construct a statistical model using multiple linear regression (MLR) analysis to predict future workday losses furthermore binary logistic regression (BLR) model was carried out to identify whether the workday loss is considered to be a major workday loss or not. MLR model revealed that a 4.5-fold increase in workdays lost for each additional 1 meter of fall height and one year increase in workers’ age will increase the workday losses by 1.3 days. Additionally, the BLR model concluded that when the age of the victim increased by one unit, victims are 1.068 times more likely to have a major workday loss, and similarly, when the height of falling increases by one unit, victims are 1.735 more likely to have a major workday loss.

Introduction Construction operations carry a high risk of accidents by their nature, and the majority of the construction activities are classified as dangerous by experts [1-3]. Furthermore, the construction workforce is specified as a labor group that has the highest risk of workplace accidents [4]. In previous studies on accident types in the construction industry, it has been reported that falls from heights are the most frequent type of accident in both fatal and non-fatal cases [5-9]. A study carried out in North Cyprus [10] examined fatal accidents and established that 53% of those fatalities resulted from injuries due to falls from heights. Another study in North Cyprus by Tözer et al. [11] established that 40% of accidents involving falls from heights resulted from wrongly assembled or misused scaffoldings. Furthermore, it has been observed that the injuries due to falls from height on construction sites are more likely to be fatal, or if they were not fatal, require a longer recovery period compared to those sustained in different types of the accident [12, 13]. This study aimed to assess falls from height- related accident data from archival reports from the North Cyprus Labour Office and evaluate these
