Beware Of Smoke From Fire!

Beware of smoke from fire!

  • Flash
Whether white (rich in aerosols or water vapour), grey (a mixture of aerosols and solid particles) or black (large solid particles), the smoke released from fires presents several risks. Beyond death from intoxication, fumes are a potential health hazard owing to the substances they contain. Smoke is also corrosive to metal structures or electronic components. Finally, they can accentuate the combustion of surrounding goods by pyrolysis.

Flooding Of A Chemical And Hydrocarbon Storage Site

Flooding of a chemical and hydrocarbon storage site

  • Accident report
  • ROYAUME-UNI

A storm surge coinciding with high tides raised the level of the Humber Estuary. The water flooded the gates of the port and filled the port to overflowing. A Seveso-classified chemical and hydrocarbon storage terminal was under 1 m of water. Following the weather alerts, the site shut down its operations and isolated its electrical power supplies. The terminal's non-essential employees were evacuated; the rest were moved to the safety of the upper floors of the operations building.

The walls surrounding the retention tanks were not flooded and [...]

Flooding Of A Chemical Storage Site

Flooding of a chemical storage site

  • Accident report
  • ROYAUME-UNI

A storm surge coinciding with high tides caused the River Tees to rise. It flowed over and eroded the dykes built to protect the local residents. A Seveso-classified port terminal containing chemicals stored in tanks was flooded 1.8 m above ordnance datum.

The terminal's employees fled to the control room on the top floor of the main building. Most of the firewalls were submerged by the water. The rising water lifted a number of partially full storage tanks, damaging their pipes and supports in the process. A number of fixtures were damaged by [...]

Mixing of incompatible products

  • Fact sheet
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 learnt from the accidentology.

CO2 extinguishing systems

  • Flash
Gas-based extinguishing processes become attractive when water cannot be used (e.g. computer equipment, audio/video archives, ship engine rooms), yet the associated risks must not be underestimated, as witnessed by the example of CO2 systems.

Rupture Of A Pipeline Within An Underground Hydrocarbon Storage Facility In Saline Cavities

Rupture of a pipeline within an underground hydrocarbon storage facility in saline cavities

  • Accident report
  • FRANCE

Around 7:20 pm, at the time of injecting naphtha originating from a refinery, a steel pipeline (DN 500-62 bar: 7 mm thick) burst open at a site dedicated to underground hydrocarbon storage using saline cavities in the heart of the Luberon Natural Park. A deafening sound combined with a sudden drop in pressure caught the attention of employees. Some 400 m3 of naphtha flowed through the opening towards a 5,000-m3 capacity retention basin located several hundred metres downstream; from this basin, a total of 200 m³ of product spilled out via 2 sl [...]

Sudden Opening Of A Crude Oil Tank Bottom

Sudden opening of a crude oil tank bottom

  • Accident report
  • FRANCE

The bottom of a 13,500 m³ containing 12,000 m³ of light crude oil tank ripped open at 8:00 am within an oil depot. The earthen dikes surrounding the retention basin withstood the wave effect; 2,000 m³ of oil still overflowed however the dikes. For the most part, this volume remained onsite and in the gutters, although 50 m³ reached the channels of the neighbouring swampland polluting 2 km of ditch network and reaching the superficial water table and 50 m³ did flow into the GARONNE. The tidal action contributed to polluting up to 40 km of b [...]

Explosions followed a fire at an oil depot

  • Accident report
  • ROYAUME-UNI

Explosions followed by fire ripped through a fuel storage depot in Buncefield, England, located just 40 km north of London. The facility was storing 150,000 t of fuel (petrol, diesel fuel and kerosene) at the time of the accident. The 1st and largest explosion occurred at 6.01 am (measuring 2.4 on the Richter scale) and was heard 160 km away. The overpressure effects from the blast reached 700 to 1,000 mbar. Two other explosions occurred at 6.27 and 6.28 am. A gigantic blackish cloud containing irritating substances drifted across southern Engl [...]
