An explosion followed by fire occurred at 3.20 am in a plant's lubricant additive manufacturing facility located in a harbour-based industrial zone. The unit, experiencing an operational shutdown for the last 3 days, appeared to be empty of all additives at[...]
At a chemical plant, a tank containing a mix of toluene-2,6-diisocyanate (TDI) / tars with a high boiling point increased in pressure and exploded around 7:40 pm. The cloud ignited 5 min later; afterwards, the fire was fed by 20[...]
At 8:45 am, a series of fires and 3 explosions broke out at a 10-ha fireworks storage site. A technician withdrew a series of electric detonators on fireworks ground packs, then a second technician sorted these detonators by colour for[...]
During cleaning operations at a chemical site that had ceased its activities, hydrogen chloride was released for a few minutes when a tank containing 11.7 tonnes of benzoyl chloride was being drained. The substance was no longer used and had[...]
A detonation occurred at 6:45 pm in a reactor on a pharmaceutical site. A worker sustained burns to the face. The device was placed under permanent inerting with nitrogen (N2). The most recent reaction held, a hydrogenation step, had been[...]
In a SEVESO-rated oil depot at 5:20 am, a truck driver notified a technician after observing an anomaly on pumping plant no. 1. The technician manually closed the pump feed valve, and the site was placed in safe operating mode[...]
