For 30 hours, 66 t of nickel sulphate, from a metallurgical plant producing nickel cathodes and 50,000 t of nickel-based chemicals, spilt into the Kokemaki River. The highest concentration of nickel measured in the river was 8,800μg/l for an instant[...]
Between 2014 and 2016, several spills of molten liquid iron occurred during unloading operations in a steel plant. The molten cast iron produced by the blast furnaces is discharged through a pouring hole in the lower part of the crucible.[...]
Placed directly on the surface of the liquid, the floating roof of a storage tank allows the reduction of emission by evaporation of certain products by the gaseous sky and thus limits the chronic atmospheric pollution generated by the most[...]
Collecting, consolidating or mixing and transportation of liquid waste is the cause of many accidents. By their nature, waste can indeed be "sensitive" materials with physico-chemical characteristics more or less identified, unlike those of raw material. The risks induced result[...]
Explosions following a molten metal / water contact are well-known accidents in the metallurgical industry, which sometimes result in significant human and material consequences. The ARIA database contains some fifty such events implying ferrous and non-ferrous metals melt. The fact[...]
Natural gas distribution networks are regularly damaged by public works vehicles during road works in the city. This fact sheet shows the main accident scenarios affecting these structures. Significant accidents, in regard of their human and social consequences or their[...]
Transfer of chemicals between fixed and mobile tanks may cause mixtures of incompatible products. This risk is all the more pernicious as the mixture usually involves "classic" substances and widely used: bleach, acid ... This fact sheet presents some lessons[...]
The Water Framework Directive of December 2000 which commits the countries of the European Union with a goal of regaining the quality of the water and the aquatic environments by 2015, supposes a better protection of these environments against any[...]
Repair, maintenance shutdown, adjustment of phase, often require the shutdown and restart of gas-powered installations. This procedure is frequently time consuming to implement, depending on the type of equipment considered (superheater, steam generator), and it can generate accidents. The following[...]
In France, the three-quarters of the total tonnage of dangerous goods transported would be by road, 15% by rail and 3% by inland waterway, with pipeline transport accounting for a very small share. In 2009, 13.8 million tons of dangerous[...]
