How does a technically insignificant incident turn into a media frenzy? This new film, produced by the BARPI, explains the sequence of malfunctions that led to the release of a highly olfactory component. A timeline presents how the media crisis gains momentum. Discover the experience of those who witnessed the crisis first hand and the lessons learnt from the event through numerous interviews.
The relative increase in disposal costs and regulatory requirements (an overall reduction in landfilling by 2025, and sorting at source of bio-waste) allow composting activities to continue to grow in France. This development is highly beneficial from an environmental standpoint, but it is accompanied by a significant increase in accidents in these activities. This document focuses on fires, the dominant hazardous phenomenon. The aim is to identify the vulnerabilities of these activities and propose measures to prevent and protect against accid [...]
A computer attack on an industrial control system (SCI) can cause an accident or a degraded operating mode in a factory. This document, with pedagogical vocation, illustrates through examples extracted from the ARIA database some cases that could lead to this kind of situation. In order to improve the security of the sites, a grid of questions completes the analysis as well as an item on cyber attacks types.
In early March 2017, the ARIA database identified 349 events involving fittings and seals/gaskets. These elements are often encountered on pipe flanges and are also essential sealing components for valves or other equipment. Insufficiently tightened flange bolts and deficient leak inspections on seals/gaskets are often the cause of an accident
Numerous forms of corrosion have been found on steel equipment used in the manufacture or transport of biogas. Three corrosion degradation modes are presented here based on events that occurred in France. It seems that corrosion should be taken into account from the design stage of the installations.
Whether white (rich in aerosols or water vapour), grey (a mixture of aerosols and solid particles) or black (large solid particles), the smoke released from fires presents several risks. Beyond death from intoxication, fumes are a potential health hazard owing to the substances they contain. Smoke is also corrosive to metal structures or electronic components. Finally, they can accentuate the combustion of surrounding goods by pyrolysis.
Runaway reactions are a major source of industrial accidents. They can occur in a wide array of sectors, including chemicals, petrochemicals, food processing, plastics and rubber manufacturing, and metalworking and are primarily caused by a loss of process control. The processes involved are quite diverse, encompassing chemical reaction, polymerisation and distillation, among others. The loss of process control is related with various factors that are examined in this article. Several accidents that occurred in France and recorded in the ARIA1 [...]
The ARIA database on technological accidents lists 26,271 events in French industrial establishments between 1 January 1992 and 31 December 2016. This large sample allows to give some trends on the exposure of the territories (regions, county) to the industrial risk.
The accident can quickly occur when the repair of an ageing equipment is not conducted in a timely manner! Often involved: an improper management of replacement parts, which are not available in due course. Patch-up jobs, consisting in reallocating pieces coming from other units without taking sufficient precautions, can also be particularly dangerous. Based on illustrative events, this flash draws a panorama of risky configurations and provides some good practices.
Ageing of industrial installations is a normal and well-known phenomenon. However, it deserves to be properly managed! Conception or construction defaults, insufficient maintenance are some of the several factors that can contribute to an uncontrolled acceleration of ageing… and that continue to lead to accidents with sometimes heavy consequences. As far as ageing is concerned, anticipation remains the key word! This flash offers an overview of the main degradation mechanisms and some lessons learnt from accidents.
Since its creation in 1999, the seminar on “Lessons Learnt from Industrial Accidents” is organized every two years by the BARPI. This event is devoted to inspectors of the environment. It is organized with the support of the European Union Network for the Implementation and Enforcement of Environmental Law (IMPEL). Below are the proceedings of the latest edition, which took place in Lyon on 31 May and 1 June 2017.
Since 2010, information collected on dam-related events has been recorded in the ARIA base. By the end of 2015, a total of 228 events had been entered into the database. This summary, written jointly by the BARPI and BETCGB bureau, presents the primary lessons resulting from their analysis. The study method has focused in particular on experience feedback regarding hydro-mechanical devices and command-control systems
Periods of cold weather are characterised by low temperatures, sometimes combined with snowfall and/or wind. Synonymous with high electricity consumption, they are often the cause of power failures and other critical systems, such as telecommunication networks, can also be affected. If energy demand is higher than production, load sharing can be implemented. But what are the risks?
In an emergency situation and primarily in the event of a power outage, only switched telephone networks (PSTN) are operational. The traditional French operator’s plan to abandon these networks in 5 years time in favour of VoIP solutions should be anticipated.
