This ARIA newsflash lists the causes of the various cases of collapse and rupture of silos compiled in the ARIA accidentology database. It reminds the appropriate questions to ask and the guides available to avoid collapses of concrete cells. As the visual checks are not sufficient, the complementary techniques to be considered are also presented.
According to the French Federation of Insurers, climate change, disruption of business sectors and cyber risks will be among the top three emerging risks by 2022. In parallel, the ARIA technological accidents database already contains numerous events involving emerging energy sectors. What are these new risks and can they be controlled?
The accident that occurred in Dieppe, France, on 17 February 2018, reminds us that the process of manufacturing vegetable oil is not without risk. Although in the present case the explosion was located in the vegetable oil extractor, the many steps of the process are accident-prone. This report presents, for each step, the associated risks and preventive measures.
Accidents caused by incompatible mixtures are not limited to newly-produced chemicals! The end of their life cycle can also be a source of risk. Several recent events in France and abroad confirm this, sometimes with dramatic consequences. This flash focusses on this issue, underlying the failures at the origin of the accidents and making a few recommendations to avoid their occurrence.
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 [...]
Conveyor belts used to handle organic materials must meet standards defined by various French ministerial orders .These texts indicate that conveyor belts must comply with standard NF EN ISO 340 or standards NF EN 12881-1 and NF EN 12881-2 (self-extinguishing or flame-retardant conveyor belts). While these types of accident had seemed to have disappeared, in recent years there have been several occurrences. Are the standards always being met?
The performance of lithium batteries and storage cells has expanded their areas of technical application (telephony, computers, electric vehicles, rechargeable hybrids and electric bicycles). This development is now resulting in an increase in the number of batteries and storage cells at the end of their service life that must be processed or recycled. But lithium batteries and cells are not harmless objects: the high reactivity of the metal means that their use and processing/recycling, present risks. This is illustrated by the following flash, [...]
Methanization is one of the key technologies of the circular economy and green growth. Within the framework of the Energy Transition Act, France has set itself the target of ensuring that 10% of the gas it consumes will originate from renewable sources by 2030. The development of methanization is one of the main levers to achieve this objective. The sector is expanding rapidly with 80 additional installations and the doubling of the production of biomethane injected into the natural gas networks in 2017. To achieve the objective by 2030, the Re [...]
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.
