In a 3,000 m² vinegar factory, a 150 m³ tank containing 40 m³ of alcohol vinegar exploded at around 9:40 a.m. while undergoing welding work. The tank, measuring 13 m in height and 4 m in diameter, was projected like a missile. It flew through the roof and landed 80 m from the building, on the Nîmes-Grau du Roi railway line. The emergency rescue services took 2 injured employees to the hospital, one of whom had been badly burned. Rail traffic was interrupted. The spilt alcohol was collected in the holding tank. The building adjoining the [...]
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.
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.
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 handling of an industrial accident is often rife with obstacles, e.g. water supply constraints, inappropriate response protocol in light of product properties, inefficient information provided by bystanders... 6.5% of all accidents recorded at France's classified sites have experienced major difficulties during emergency responses. This fact sheet offers a sampling of the errors to avoid and serves to better anticipate response difficulties, by drawing from an analysis of 395 events post-2010.
The use of an inerting process is a means of intervention used in a fire in grain silos. However, it remains uncommon. As part of its work, the BARPI wrote a synthesis on this process based on the accidents contained in the ARIA database. This synthesis addresses the following issues : What are the conditions of use of these devices and what are the difficulties experienced by those that are involved in the implementation of these devices?
Over the past 3 years, more than 40 fires involving silos containing wood chips or sawdust have been recorded in the ARIA database. In such instances, operational difficulties are commonly encountered by emergency services (lengthy interventions, vulnerability of storage structures, etc.). Each response is therefore unique and requires comprehensive knowledge of all potential risks.
Many industrial accidents involve work conducted within confined areas, where the primary risk has been generated by the latent or accidental presence of an either flammable, toxic or simply oxygen-deficient atmosphere. The objective of this analysis is to build awareness among actors. It relies upon an analysis of 80 illustrative accidents selected from the ARIA database that involve classified facilities.
The present analysis is based on 2,686 events recorded between January 1st, 1992 and August 31st, 2009 in relation to farming activities of beef cattle, pigs, rabbits, poultry and game birds. The purpose of this document is to characterise general accident trends, with an emphasis on drawing lessons to assist actors in the field of risk prevention.
We need to pay special attention to the circumstances under which accidents in silos storing plant products take place. Experience shows that the frequency of accidents is far higher during the working phase including the preventive or curative maintenance, change, assembly or disassembly of facilities. This is also true for both staff technicians carrying out operations in the silo and subcontractors working in a sector where the risks are often underestimated.
