Today hazard studies are a self evident part of a project plan while creating a new process or making changes in an existing one in the chemical industry. Therefore it is important to make the hazard studies as efficient as possible. The objective for this thesis was to optimise the hazard study processes based on the main methods presently used at Neste Oil Oyj, Neste Jacobs Oy and Borealis Polym
This essay describes a comparison method that SÄRF can use to work in a simpler way to describe how the protection against accidents is within its area of activity. The method assume from the IDA-tool which is a tool The Swedish Rescue Services Agency has developed so the Swedish municipalities should be able to compare their own protection against accidents.
This report describes the differences between a risk analysis and a vulnerability analysis, when applied to a Flue Gas Desulphurisation (FGD) facility. A Preliminary risk analysis complemented by an Event Tree analysis is compared with An App-roach to Vulnerability Analysis of Complex Industrial Systems by Einarsson and Rausand (1998). The focus of this report is to demonstrate the different steps
In November 2004, Valdivia Cellulose Pulp Plant started operating in San Pedro de la Mariquina, 56 kilometers north-west of Valdivia in southern Chile. A few months later a decrease in the population of the Black Necked Swans (Cygnus melancoryphus) in the Carlos Anwandter Sanctuary, near the discharging point of the mill, was discovered. The aim of the thesis was to evaluate three alternative disc
According to the legislation for accident prevention and protection, which took affect January 1st 2004, all Swedish municipalities have to establish plans of actions for accident prevention and the fire service. Municipal risk analyses should constitute the foundations for these plans of actions. The purpose of this report is to describe and meet the requirements on municipal risk and vulnerabili
This master of thesis evaluates three methods for classification of areas where combustible dusts are or may be present. The methods have been applied to fictitious plant where chipboards are pro- duced. Current European directives that concern combustible dusts are also evaluated. The aim of this report is to accomplish a guiding work methodology for handling of combustible dust in the process in
The use of operating procedures at a nuclear power plant is of great importance. But improper composed procedures will increase the probability for mistakes. An inspection of the operating work at Ringhals AB carried out by WANO, has shown shortages in the way procedures are used. WANO suggests that procedures should be graded according to their importance of safety for the facility and for usage.
The development of modern enterprises goes toward more complex supply chains with many links and worldwide transportation. The trend of using centralized warehousing as logistic setup has grown more popular during the last years. This development has created new risks and implied increased vulnerabilities for many enterprises. To manage these issues the area of Business Continuity Management has g
The offshore industry means high risk activities on a daily basis and with a location far away from solid ground and handling large amount of flammable substances, these are two strong reasons that make it important to keep a high level of safety onboard. One of these safety measures is passive fire protection (PFP), in this report this means the surface coating (Chartek) protecting the load beari
The main objective of this master’s thesis is to construct a model, which can be applied on a region to investigate the possible future climate changes. This investigation is intended to lead to an analysis of the region’s changing risks regarding natural hazards affected by climate change. The hazards investigated are hydrological and climatological hazards and consist of cyclone, tornado and flo
The risk for a ship collision is usually predicted to be one of the dominating risks for an offshore installation. The subject of this thesis originated in a need for continuous update and review of the models for assessing the collision risk, so that the technical development and management changes of today are reflected. The risk for collision is governed by the actions of the ship, which depend
The aim of the thesis is to present a safety, health and environmental management system based on ISO 14001 and OHSAS 18001 for Industry Park of Sweden. The resulting system is based on a gap analysis between an ideal system and IPOS existing management system. The resulting management system emphasis safety culture before regulations and lets the tenants of the Industry Park proceed with their in
In Texas, 2005, a vapour cloud explosion occurred during a refinery outage and start of a process unit. Fifteen people died and 180 persons were injuried. The majority of the killed were in temporary buildings. The accident has brought attention to the increased risks during starts and stops related to outages. In this thesis a risk analysis method is proposed and applied on the refinery in Lyseki
Aerial spraying is common procedure at banana plantations in Costa Rica even though the plantations often are situated very close to villages. The fungicide Mancozeb, which is metabolized into the more toxic substance ETU, is one of the pesticides used in aerial sprayings. This thesis has evaluated the exposure of ETU to children living in one of these villages and compared that exposure to differ
Almost all businesses, in today’s market, builds on complex supply chains operating on the global market. The competition is no longer between individual companies but between different supply chains. This creates new risks for both the individual company and the companies operating in the supply chain. Cooperation between small and medium sized business partners can create possibilities and high
This paper gives a short summary of the authors’ master thesis that delivers an analysis of the requirements of municipalities concerning their risk management, with the focus on toxic industrial materials. The conclusions rests upon; a literature study, a qualitative questionnaire, 10 interviews and a quantitative questionnaire, which all have been performed in the counties of Blekinge, Kalmar an
Most businesses today employ risk management systems as a part of their daily activity. Traditionally this is being done using a silo based approach for each field of the enterprise e.g. one system is being applied to safety management and another to quality management. A new trend in risk management systems is an increased level of integration between separate systems, changing risk management fo
This master thesis is written at the request of Kockums AB to solve the need for flexible fire barriers on submarines, particularly for the future submarine class A26. The report uses event tree analysis to demonstrate that a lower fire resistance classification for decks and bulkheads, compared to the prescriptive rules, is sufficient to obtain a satisfactory level of safety. The thesis also incl
The existing Swedish regulation of fire dimensioning regarding structures are separated into two separate parts which isn’t unproblematic. This sets demands for a new regulation based on a holistic view that can reveal how a fire in a compartment can affects the whole building. This compared to the existing demands that only could quantify a certain time limit as a demand in only a single fire cel
Queuing during evacuation is a phenomenon that has to be regarded when designing large buildings with high occupant loads. In theory it would be possible to eliminate or at least reduce the queuing time when evacuating a building if the building is designed with a large number of exits. The problem is that exits equal money and for that reason it has to be assumed that the building constructors’ a
