### Overview of Workers and Occupational Injuries  
The numbers of construction workers and occupational accident details are mentioned in Table 1. It also describes an overall increasing trend in the number of construction workers in Hong Kong since 2011. During the analysis, the mean numbers of construction workers were around 88,229, while the mean occupational injuries and fatalities were found to be around 3597 and 20 respectively. The total numbers of occupational injuries in Hong Kong were significantly increased yearly. However, there was a mixed trend in incident rates and mortality rates throughout the analysis period. On the other hand, both mortality rates (9.27), as well as incidence rate (3.6), were shown to be significantly lower in 2016. However, the incidence and mortality rate were increased in 2017 which required a huge attention to tackle this situation for human well-being at the workplace. Table 2 indicates the overview of occupational injuries with respect to the accident type from 2011 to 2017. The total numbers of occupational injuries (OIs) were increased over the year with several accident types such as fall of a person from height and slip, trip or fall on the same level, injured while lifting or carrying as shown in Table 2. Overall data has shown a fluctuation, increasing and decreasing in fatal occupational injuries (FOIs) over the analysis period. From the 2011 to 2017 data analysis, there was a mixed trend in OIs and FOIs in the Hong Kong construction workers. However, in 2016, there were a lower number of FOIs and OIs as compared to all other years. Result analysis also showed there was a decreasing OIs trend with an increasing number of workers of construction workers throughout the analysis period. With respect to the accident types, the higher number of FOIs and IOs occurred in \"Fall of person from height\" through the analysis period. Moreover, the most dangerous accidents types which cause more OIs were slip, trip or fall on the same level and injured while lifting or carrying. On the other hand, in the second accident type most more FOIs were striking against or struck by a moving object, contact with electricity or electric discharge and Struck by falling object. Results of the analysis showed an increasing trend in OIs from 2011 to 2017 among construction workers. \begin{table}
