Affective e-OHS training system for construction

Previous studies on causal analysis of accidents in construction suggest that unsafe behaviours of workers have been repetitive causes of accidents in a significant percentage of cases. For example, Haslam et al. (2005), upon analysing 100 construction accidents, uncovered that workers’ behaviours have been involved in over two-thirds (70 per cent) of accidents. Hinze et al. (2005) and Abdelhamid and Everett (2000) also reinforced that a vast majority of accidents on construction sites occur due to one of the following worker-behaviour-related root causes:

v failing to identify and control an unsafe condition that existed before an activity was started or that developed after an activity has started;

v inaccurate perception of risk, with feeling of invulnerability and ‘it won’t happen to me’;

v overlooking safety in the context of heavy workloads and other priorities; v deciding to proceed with a work activity after the worker identifies an

existing unsafe condition; and/or v deciding to act unsafe regardless of initial conditions of the work

environment (taking shortcuts to save effort and time).
