Behaviour factor

In this chapter a simple model of incident causation is presented and the relative importance of three groups of factors contributing to industrial safety will be discussed Technical, Organisational and Behavioural Factors. Historic trends or fashions focussing on one of these thpee factors will be described, followed by recent results of the situation in the chemical process industry in the Netherlands.

Within a species, groups of individuals become reproductively isolated because of geographical or behavioural factors see isolating mechanism), and over time may evolve different characteristics and form new and distinct species. 2. (in chemistry) A chemical entity, such as a particular atom, ion, or molecule. 

The comparison between the results of the two methods highlights that the evacuation times obtained by the simulation software are higher respect to those ones deduced from NFPA 130 criteria. It is important to recognize that in the last case the computed egress times do not consider behavioural factors such as decision-making and orientation time and therefore do not constitute an accurate measure of the time required for the station to be emptied. These times provide an assessment of the minimum time required for all passengers to evacuate the station. The simulation, instead, takes into account also behavioural factors that generally increase evacuation times and therefore provides more realistic results.

The crucial point is that the behavioural factors which determine the likelihood of intentional risk-taking are quite different from the factors which lead to unintended errors. 

In this chapter two test cases have been considered. In the first one structural optimization is used for performing a critical assessment of the behaviour factor, while in the second one a design procedure is proposed for defining torsionally balanced layouts. 

In the framework of this study, the RC building has been optimally designed to meet the Eurocode (EC2 and ECS) or the PBD requirements. According to ECS the lateral forces were derived from the design response spectrum (5%-damped elastic spectrum divided by the behaviour factor q) at the fundamental period of the building. Concrete of class C20/25 (nominal cylindrical strength of 20 MPa) and class S500 steel (nominal yield stress of 500 MPa) are assumed. The base shear is obtained from the response spectrum for soil type A (stiff soil 0= 1.0, with characteristic periods T1 =0.10 sec and T2 = 0.40 sec) and a PGA of 0.31 g. Moreover, the importance factor yi was taken... 

In this chapter, structural optimization is considered for the assessment of (i) the behaviour factor q with respect to limit state fragiHties and (ii) the minimum torsional response of RC buildings under different design considerations in three hazard levels (frequent, occasional and rare). The designs were assessed with respect to the initial as well as to the total life-cycle cost. From the present study the following conclusions can be drawn ... 

It should be realized that such unsafe acts or hazards as those referred to by Heinrich can be described in a multitude of ways and this is one of the difficulties in using this model. It does not provide a common description or classification which can serve as a basis for scientific study. It also involves both human behavioural factors and mechanical or physical factors within the same classification.

Third, the evidence presented in this book rests on intellectual foundations that came from the advances in many fields outside the traditional basic sciences on which most contemporary academic engineering discourse is based. These advances now provide powerful explanatory insights into many more of the human behavioural factors that shape contours of engineering feasibility the issues that demand most attention from engineers in their workplaces. Systematic observations have revealed many of these issues. The predominance of technical coordination and the human perception and behaviour issues that influence sustainability are examples of these factors. 

Job safety analysis involves the identification of all the accident prevention measures appropriate to a particular job or area of work activity and the behavioural factors which most significantly influence whether or not these measures are taken. 

Management is concerned with people at all levels of the organisation and human behaviour, in particular personal factors such as attitude, perception, motivation, personality, learning and training. Communication brings these various behavioural factors together.
