Quantitative assessment of explosion risk in workplaces

The Directive 99/92/EC deals with the safety and health protection of workers potentially exposed at explosive atmospheres. The application of this Directive requires the assessment of specific risks due to the presence of potentially explosive atmospheres. These can generally be originated by releases of flammable substances typical of industries classified at major hazard, but they often could be generated also in all other industries where flammable materials are handling. Risk assessment of explosive atmospheres is required in both the cases, to this purpose, in this article a quantitative approach has been proposed. The paper describes the main aspects of the methodology, based on a probabilistic risk assessment, and finally its application to a case-study.

Following recent severe natural events, attention has been focused on industrial installations located in areas prone to natural hazards. This work concerns the study of volcanic Na-Tech events (i.e. technological risks triggered by natural causes) and aims at defining a procedure for the representation of the vulnerability of industrial facilities in areas with the potential volcanic ash fallout by means a Geographical Information System (GIS). Here, we focused on the construction of a semi-automatic procedure for the vulnerability mapping for cases where input data is very limited; it is based on the use of a specific tool named ModelBuilder of the ArcGIS software.

The question of how the effects of management and organisational variables can be incorporated into assessment of frequency of loss containment events is currently of considerable interest. Usually these typology of events arises from an uncontrolled accidental phenomena or a combination of active and latent human errors in areas such as design, operations and maintenance. In the 2006 a development of a methodology for the quantification of the effects of measures of risk prevention or mitigation on the frequencies of rupture of pipework has been presented, the approach is based on the methodology proposed by Papazoglou in 1999. Taking advantage of Papazoglou methodology the estimation of these effects has been achieved through the definition of the links between the failure causes that are the origin of incidents and the measures adopted by the company in order to prevent and/or to mitigate them. After an overview on the failure causes in piping, the aim of this paper is to present the application of the recent modified methodology.
