Explosion Under A Bridge Deck Following A Fire Which Caused A Gas Leak

Explosion under a bridge deck following a fire which caused a gas leak

  • Accident report
  • FRANCE

At around 8:55 p.m., a natural gas explosion (vapour cloud explosion - VCE) occurred on a bridge pier containing a polyethylene natural gas pipeline (DN125) passing through a stainless steel sheath, and a steel pipeline (DN 114). A fire had initially broken out at around 8 p.m. in a squat on another pier. The heat fluxes released caused the steel pipe to bend and the polyethylene pipe to melt. Natural gas was thus able to migrate through the sleeve via its couplings and form explosive pockets.

Four firefighters injured during the interventio [...]

Ensuring Safety When Transporting Dangerous Goods Within Classified Facilities

Ensuring safety when transporting dangerous goods within classified facilities

  • Fact sheet
Since 1990, a total of 784 accidents involving transportation of dangerous goods within Classified Facilities have been recorded in the ARIA base. The percentage of this type of accident has nearly doubled over the past 10 years. The transport of dangerous goods is not a “productive” activity, but it remains vital to industrial operations. This fact sheet describes the risks associated to these activities and the meaures to be taken.

Fire followed by explosions at a dangerous goods transport company

  • Accident report
  • FRANCE

At about 6:30 a.m. on a Sunday, a fire was detected in a dangerous goods transport (DGT) company classified as a lower-tier SEVESO company. The fire broke out in a parked tanker lorry. With a capacity of 19 t, it contained just 1.5 t of liquefied petroleum gas (LPG). The fire spread to several other tanker lorries. The fire brigade, contacted by a third party, arrived at the scene at 7 a.m. The operator initiated its internal emergency plan, while the emergency services established a security perimeter and sprayed water on the accident.

At 7: [...]

Seal Boxes : Not To Be Mistaken As A Cure For Ageing

Seal boxes : not to be mistaken as a cure for ageing

  • Flash
Commonly used to plug leaks on pipelines, seal boxes serve stop discharge flows without entirely shutting down production. Despite this advantage, several accidents have shown that this type of remedial action is not sustainable and moreover necessitates regular monitoring during operations while awaiting definitive repairs.

Rupture Of A Crude Oil Pipeline

Rupture of a crude oil pipeline

  • Accident report
  • FRANCE

A longitudinal rupture occurred at approximately 6 a.m. on a crude oil pipeline (DN 500, buried depth: 1 m in clayey soil; commissioning date: 1965; pressure: 69 bar) at 1.5 km from a nature reserve. No disturbance or pressure surges in the pumping operation were observed before the accident. The pipeline was shut down and isolated when alarms sounded in the control room. Soil and trees over 6.4 ha were polluted by hydrocarbons.

After locating the leak, the operator initiated its safety and intervention plan (SPI) at around 8 a.m. A safet [...]

Transport of waste in tank trucks

  • Fact sheet
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 from the emergence of dangerous chemical or biological reactions, sometimes untimely and violent, with sudden rise of temperature. Discover some cases of notable accidents in the fact sheet below.

Rails accidents in urban areas

  • Fact sheet
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 goods were transported by rail (79.4 Mt / road), i.e. 17% of rail freight; Transported 3 times out of 4 by whole trains, 95% of wagons being tank cars which transported 6 Mt of flammable liquids, 5.2 Mt of various chemicals and 2.6 Mt of compressed, liquefied or dissolved gases pressure. Discover in this fact sh [...]

Delivery Of Hazardous Material By Tank Truck

Delivery of hazardous material by tank truck

  • Flash
While the delivery of hazardous materials by means of road transport onto an industrial site constitutes a relatively commonplace operation, all too often it leads to overly taxing the onsite reception capacities. In addition to generating economic losses, these discharges are potentially hazardous for both human health and the environment.
