Toluene Tank Explodes at Ercros’s Aranjuez Plant With No Injuries Reported

The company cites a pressure spike in an effluent-treatment tank as the likely cause, with on-site checks continuing.

Overview

  • The blast occurred around 8:30 p.m. Tuesday in a tank used for the treatment and recovery of liquid effluents that contained toluene.
  • Firefighters from the Community of Madrid, local and national police, and SUMMA 112 responded, and crews ventilated the facility after confirming no gas hazard.
  • Ercros and emergency services reported no injuries, no detected emissions, and no environmental impact, saying the situation was contained with the plant’s own resources.
  • The detonation was heard in several parts of Aranjuez, and the mayor, Miguel Gómez Herrero, and plant director, Mari Carmen Cruzado, released a video to reassure residents.
  • The Aranjuez site, active since 1951 with more than 200 employees producing generic pharmaceutical ingredients, has a history that includes a deadly explosion in the 1990s.
