This paper analyses current trends in the development and use of acute exposure levels in Europe for the implementation of the Seveso II Directive [Council Directive 96/82/EC of December 9, 1996 on the control of major-accident hazards involving dangerous substances. Official Journal of the European Communities, vol. L 10, January 14, 1997, Luxembourg, pp. 13-33]. It also describes a new initiative to develop a European methodology for deriving acute exposure threshold levels that responds to emerging needs in this area. The need for acute exposure values to predict human health effects of potential accidents on exposed populations has burgeoned in recent years. As the driving legislation for managing industrial hazards in Europe, the Seveso II Directive has particularly influenced this trend. Yet at this time it is questionable whether the availability and range of acute exposure values for toxic substances has kept apace with the growing need. Results of a survey of Seveso II competent authorities in the EU-15 revealed that a variety of different types of acute exposure values (AEGLs, EPRGs, etc.) are used for Seveso II applications. Moreover, a comparison of these values indicates gaps in coverage of substances as well as inconsistencies in terms of how health effects and exposure periods are defined for each type. These findings highlight an opportunity for greater collaboration on scientific inputs to application of the Directive in Europe. The ACUTEX project is an EU-funded research project aimed at furthering scientific exchange and collaboration in support of the development of acute exposure levels for toxic substances in Europe. Its goal is to develop a European methodology for deriving acute exposure threshold levels (AETLs). In particular, it provides the possibility for a common European platform for developing additional acute exposure values to meet emerging needs and cover more chemical substances. To maximise success, the work plan is designed to meet two very important challenges, the need to complement and add value to the existing array of acute exposure methodologies and the necessity of meeting requirements of a diverse range of European stakeholders. As such the project will draw on collaboration among European scientists and process of deliberation among stakeholders to deliver the following key results: (1) to facilitate wide acceptance of the methodology in Europe by both the scientific community and communities of different end-users; (2) to provide greater equivalence and transparency in implementation of the Seveso II Directive across the Member States, specifically through the development of common scientific bases for assessing risks and making risk management decisions related to toxic releases; (3) to produce a methodology that remains open to future collaboration on derivation of acute exposure levels on a European and a global basis.
Variable message signs (VMS) can provide immediate and relevant information to road users and bilingual VMS can provide great flexibility in countries where a significant proportion of the population speak an alternative language to the majority. The study reported here evaluates the effect of various bilingual VMS configurations on driver behaviour and safety. The aim of the study was to determine whether or not the visual distraction associated with bilingual VMS signs of different configurations (length, complexity) impacted on driving performance. A driving simulator was used to allow full control over the scenarios, road environment and sign configuration and both longitudinal and lateral driver performance was assessed. Drivers were able to read one- and two-line monolingual signs and two-line bilingual signs without disruption to their driving behaviour. However, drivers significantly reduced their speed in order to read four-line monolingual and four-line bilingual signs, accompanied by an increase in headway to the vehicle in front. This implies that drivers are possibly reading the irrelevant text on the bilingual sign and various methods for reducing this effect are discussed.
"How did we get into this situation?" How many times has this question been asked at the outset of an investigation, or more importantly, at the completion of an investigation? If the answer is not readily and thoroughly apparent, the investigation is not complete. Subsequently, those who will have the responsibility for correction of the conditions leading to the incident will not have all the information necessary to properly complete their task. For many years, in many writings, the Human/Machine interaction and its impact on process design has been discussed. The same impact should be examined when performing incident investigations. Consideration of the interaction of human and machine along with the environment in which they are used has long been recommended by the National Safety Council, in both design and investigation.
