Early analysis of technical or organisational changes

02/06/2017
Fact sheet

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 [...]

Pyrotechnics : why did the technician fail to follow the procedure ?

05/06/2015
Fact sheet

In the pyrotechnics sector, 12% of accidents are related to inappropriate human intervention: mainly non-compliance with procedures (since the creation of the ARIA database, 132 accidents are in this case out of a total of 1076). Based on real examples, the purpose of this fact sheet is to present the typical configurations in which operators are knowingly bypassing procedures and investigating the root causes associated, in the different contexts described.

Accident report
ALLEMAGNE

In a chemical plant, a leak of effluents containing acetonitrile (a harmful and flammable solvent) from the process wastewater system lead to groundwater contamination. As the network was used only sporadically, the duration of the leak could not be accurately determined. A maximal estimate gave 557 days. The potential loss is estimated to be 61 t of acetonitrile.

Wells were established to try to recover the pollutant through pumping and to sample the groundwater. Three tonnes of acetonitrile were recovered by pumping operations over a period [...]
