Conveyor Belt Fires: Are The Standards Being Met?

Conveyor belt fires: Are the standards being met?

  • Flash
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?

Large-scale Fire In A Wood Chip Storage Facility

Large-scale fire in a wood chip storage facility

  • Accident report
  • FRANCE

At around 3 a.m., a deep-seated fire broke out in an outdoor 50,000 m3 woodchip storage in a waste recycling facility (24 m high, located on the facility's property line). White smoke was emitted above the urban zone and the highway. Access to the site was difficult for the firefighters because of the volume of the stack. The wind propagated the flames. An expert specialised in deep-seated fires was called upon. The CASU (the INERIS Emergency Support Unit) was asked to provide models of smoke dispersion, given the possible human consequences [...]

Early Analysis Of Technical Or Organisational Changes

Early analysis of technical or organisational changes

  • 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 [...]

Leakage of ethylene under pressure in a petrochemical complex

  • Accident report
  • FRANCE

Damaged compressor : dual-stage compressor compressing ethylene from 3 to 33 bar. It operates alternately with the main compressor. On the day of the accident, it had been in operation for 43 days since its last maintenance five months prior. It was located next to two other compressors (Nos. 2 and 3). The latter two had been shut down and automatically isolated upon activation of the gas detectors, which was not the case for the damaged compressor No. 1, which had to be isolated manually from the control room.

In a petrochemical complex, a [...]

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

  • 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.

Chronic leakage of toxic effluents in a chemical plant

  • 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 [...]
