Cooling Towers: Legionnaire’s Disease Still Running Rampant!

Cooling towers: Legionnaire’s Disease still running rampant!

  • Flash
The group outbreak of Legionnaire's Disease in the Lisbon suburbs in 2014 has provided a sad reminder: the propagation of legionellae within the water circuits of cooling towers is a likely scenario and one capable of causing major health impacts whenever water droplets are dispersed from these towers. The regulatory regime for preventing the risk of legionellae stemming from cooling towers has been substantially modified. The regulations currently in effect in France are considered by experts to be among the most elaborate. Nonetheless, new cas [...]

Two explosions ripped through a petrochemical complex at night

The blasts occurred around 3 am in the storage zone of a petrochemical plant: 2 tanks ignited and their floating roofs were damaged. The 1st tank contained 11,300 m³ of pyrolysis gasoline (a mix of diesel, butene, toluene and butadiene). The 2nd tank, located 300 m away, was holding 48,000 m³ of naphtha. On-site fire-fighters, backed up by neighbouring facilities' response teams, arrived on the scene in large numbers. The complex operator activated the internal emergency plan and n [...]

The summary of this accident has not yet been translated. In the meantime, please refer to the French summary :

Dans une usine chimique, une fuite d'effluents contenant de l'acétonitrile (solvant nocif et inflammable) provenant du réseau des eaux usées de procédé entraîne une contamination des eaux souterraines. En raison de l'utilisation sporadique de ce réseau, la durée de la fuite n'a pu être déterminée avec précision. Une estimation maximaliste a donné 557 jours. La perte potentielle est estimée à 61 t d'acétonitrile.

At 2:30 pm inside a paper mill located 5 km east of Arcachon Bay, a 5,000-m³ black liquor tank ruptured. Black liquor is a highly alkaline paper manufacturing residue composed of organic matter, soda and other chemical products; it serves as a fuel for boilers used in the paper pulp production process. 4,000 m³ of this product at 85°C spilled over a 2 to 3-ha area within the mill. After destroying a low retaining wall, 100 m³ of product overflowed into the LACANAU and then the LEYRE Rivers. The rest of the liquor was channelled into a backu [...]
