An approach for supporting decisions on land use around chemical sites - along with a software decision support system (DSS) - based on multi-criteria decision analysis (MCDA; and particularly on the establishment of the set of efficient solutions and letting the final selection depend on local procedures and value tradeoffs) is being illustrated through a… (More)
This paper describes the development of a management model to control barriers devised to prevent major hazard scenarios. Additionally, an audit technique is explained that assesses the quality of such a management system. The final purpose of the audit technique is to quantify those aspects of the management system that have a direct impact on the… (More)
Duijm, Nijs Jan / Safety-barrier diagrams as a safety management tool.
The sciences analyzing and describing risks are relatively new and developing, and the associated terminologies are developing as well. This has led to ambiguity in the use of terms, both between different risk sciences and between the different parties involved in risk debates. Only recently, major vocabularies have been compiled by authoritative agencies.… (More)
A methodology is described that enables to use safety management audit assessments and safety culture questionnaire results for estimating the reductions in the reliability of safety barriers in major hazard plants. The critical issue is the establishment of weight factors in combination with the anchoring of "good" safety management. A method is proposed… (More)
The environmental impact and safety aspects are assessed for six different techniques for disposing decommissioned ammunition. These are open burning and open detonation (OD), closed detonation (CD), fluidised bed combustion (FBC), rotary kiln (RK) Incineration, and Mobile furnace (MF) Incineration. The assessment is performed in the form of a… (More)
Hazards are identified for six different techniques for disposing decommissioned ammunition. Use has been made of functional modelling as a basis for hazard identification. Risk levels are estimated based on general accident rates in the chemical industry. The disposal techniques are "open burning" (OB), "open detonation" (OD), "closed detonation" (CD),… (More)
