Design and validation of a predictive tool for work accidents at construction sites

Abstract

The most used indicators related to occupational safety are 
indicators that generally refer to accidents that have occurred, 
they are lagging indicators, because the measures that they 
offer can no longer avoid the accident that has already 
happened. 
This article presents a tool based on the use of leading 
indicators that, by contrasting them with certain lagging 
indicators, allows the predictive evaluation of the possibility of 
occurrence of work accidents in the construction sites in which 
it is applied. 
This paper explains the methodology followed for the design of 
the predictive tool and discusses it applicability. The obtained 
results lead to establish significant statistics correlations 
between some of the leading indicators formulated in the 
survey and accident data occurred in each case (lagging 
indicators), and therefore the predictive tool of work accidents 
in the construction works can be validated. The predictive 
capacity get 85.0% for minor accidents and 82.8% for major 
accidents
