In a fine chemistry unit, the temperature of a reactor abnormally surged (tripping the alarm) during the casting of an aldehyde-phenol compound into a mix of hydrogen peroxide, maleic anhydride, methylene chloride and dimethylformamide. The technician shut down the metering[...]
A reaction between cyanuric chloride and sulphanilic acid ran away inside a fine chemistry unit. Water, sulphanilic acid and cyanuric chloride were loaded into an 8,000-litre reactor. According to the new operating protocol, 1 tonne of ice was supposed to[...]
In a bituminous materials depot run by the BTP company and comprising 17 tanks, one of which contained hydrochloric acid, the vapour space of a vertical container filled to half its "cut-back 0/1" capacity (i.e. 18 tonnes of liquefied bitumen[...]

An explosion occurred at 1:30 am inside an urban heating plant (500 MW, 6,000 m² floor area), with the energy dissipated into the ground estimated at the equivalent of a 50 kg charge of TNT. Operational since 1987, this heating[...]
Inside a pectin extraction unit at a food processing plant, 102 m³ of nitrous vapours were discharged into the atmosphere during 1 or 2 min, following bursting of the rupture disc on a reactor. Fire-fighters were called to the scene,[...]
Fire followed by explosion struck a (32-m³) road tanker during a transfer operation at a depot storing home heating oil and diesel (3 underground 30-m³ tanks, 3 aboveground 70-m³ tanks) subsequent to a fuel oil leak at the transfer hose[...]
An exothermic runaway reaction triggered an explosion and subsequent fire in a workshop at a pharmaceutical plant during a reduction step carried out inside a reactor inerted with nitrogen; this reduction was being performed in an anhydrous environment on an[...]
An explosion occurred around 12:30 pm on a cadmium vaporization column inside a unit devoted to refining zinc by means of fractional distillation. A cloud of zinc vapour and zinc oxide powder (?), combining to form an opaque white fog,[...]
While transferring concentrated liquid waste inside a chemical plant, a tanker lorry driver died. He arrived at 9:30 am at the reception area and was joined in the transfer zone by the plant's safety engineer. The transfer from tank to 2[...]
