Abstract:

This paper proposes a new three-dimensional risk assessment model which is based on the traditional two-dimensional risk matrix by adding a new degree of freedom representing the number of overlapped or interacted risk layers. The proposed model uses a geographical information system to managing health and safety through different stages like prevention through design, working safely and responding to undesired situations through providing the required information about spatial based risks. The new model helps the assessor to make realistic hypotheses, avoid uncertainty and improve the accuracy of determining the likelihood and consequences. In addition to the new risk assessment model, a new electronic geographic and safety information communication system is recommended in order to make the new risk assessment model more effective and improve the management of occupational health and safety. The electronic system integrates geographical based data and safety related information to produce risk maps in different places inside and around the workplace. Such a system will facilitate access to data anywhere at all times, enhancing dynamic risk assessment. Finally, the new risk assessment model and the electronic information system are expected to contribute in improving the management of health and safety, assessing risks and preventing losses.
