Since 2016, 25% of accidents in ICPEs (classified facilities for environmental protection requiring authorisation or registration), impacting people and property, have been caused by multiple failures involving equipment faults or human interventions. Most initial post-accident verifications focus on the incriminated system: did it function as intended and were the necessary human actions taken? One failure is already one too many; this is all the more true for multiple failures. It is therefore important to know how to analyse cases of multipl [...]
More and more plants and factories are being automated and the amount of information being transmitted over telecommunication networks is increasing. The general consensus is that there is a risk. However, is it possible to delineate this risk and evaluate its consequences — particularly its environmental consequences — by analysing the events logged in ARIA’s database? For an answer, download this flash.
Forklifts are often used for handling operations. They allow to carry toxic, flammable, explosive and other dangerous products on pallets. Manoeuvres can lead to hazardous situation with serious consequences : pollution or contamination following a split of products, fire ignited on hot spot created by the friction of the forklift forks, explosion of a fuel storage or electric batteries, intoxication due to CO/gas emission from the forklift… This newsflash presents 4 latest and significant technological accidents, caused by a handling with a f [...]
Fluid transfer is a common industrial operation. However, the incorrect positioning of transfer circuit during such operations, also referred to as poor alignment, is the cause of many accidents. This study, based on 372 events in the ARIA database, presents their characteristics and lessons learnt.
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.
An early analysis of technical or organisational changes often proves to be insufficient, or overlooked altogether, resulting in numerous accidents. In many cases, it is simpler and less costly to use existing installations in order to develop or advance a particular process. Such a step however does require an in-depth analysis of the modifications, combined with an accurate identification of the risks tied to anticipated changes. This fact sheet presents a few examples of accidents before revealing the tools available to enable the successful [...]
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.
Every year in France, many deaths and injuries result from accidents involving household uses of gas. These events, which occur in individual dwellings off the natural gas distribution networks, are caused by a wide variety of devices so common in our day-to-day lives, e.g.: gas cookers, boilers, 13-kg bottles of butane and propane. This document presents, in the form of graphic indicators, the main characteristics, typologies, circumstances, causes and consequences of the set of accidents analysed relative to household uses of gas.
Although they are restrictive, power outages in individual homes remain mostly innocuous. On the other hand, in the case of industrial sites, any disruption to the power supply can result in a sudden shutdown of the installations and serious consequences for the units, personal safety and the quality of the environment. This fact sheet shows some notable accidents.
Under standard operation of the installations, the thermal insulation and its protective sheath can complicate the detection of an anomaly, such as the local overheating of a part of equipment, leakage or releaf of chimicals or even of a possible heat transfer. Problems of corrosion under insulation can also be highlighted. This fact sheet presents some cases of accidents involving heat insulation.
