Mobile acetylene cylinders : Hazard potential not to be underestimated!

01/08/2018
Flash

Mobile acetylene cylinders are present in all sectors of activity owing to their common use on welding machines. Even if they look like risk free, these cylinders are real hazard potential ! Five major accidents in France since the beginning of 2018 drive us to remind to users and owners the risks associated to these cylinders.

Video “From incident to media crisis”

15/06/2018
Movie

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.

Beware of smoke from fire!

Flash

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, case studies, lessons learned

20/11/2017
Press article

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 [...]

Geographical distribution of industrial accidents in France

01/09/2017
Flash

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.

Cybersecurity and industry

18/08/2017
Study

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.

Seal/Gasket accident study

17/07/2017
Flash

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

Biogas and corrosion

11/07/2017
Flash

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.

Mastering the ageing of facilities: a long-term investment to avoid accidents!

06/07/2017
Flash

When operating an industrial site, it is essential to research its economic optimisation, though systematic reasoning in terms of the cost/benefit ratio has its limitations! Minimising the risks when the initial signs of aging appear or trying to keep one's equipment going until it eventually falls apart can be very dangerous. And sometimes, the financial consequences of accidents are much higher than the investments related to quality design and regular maintenance. This is illustrated below by several recent events presented in this flash.

Ageing and management of spare parts: a major challenge

26/06/2017
Flash

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.
