Accidents associated with ammonia
This study foccuses on accidents associated with ammonia and refrigeration.
Mix of incompatible products
The accidents presented in this flash involve chemical reactions between incompatible products inadvertently placed into contact with one another. Encountered in all types of activities, such accidents are frequent and occur not only during the delivery of chemical products (wrong[...]
Explosion in an plant manufacturing polymers

Explosion and fire at a chemical plant
In a chemical plant producing mainly cellulose derivatives, an explosion and fire occurred at about 4 pm during the restart of a production line stopped for 9 h after a breakdown. The commissioning of the vacuum belt filter by the[...]
Methomyl explosion and fire at a pesticide plant
Inside a pesticides plant with 520 employees, a 17-m³ reservoir used to treat methomyl residues in a methylisobutyl ketone (MTBK) solvent suddenly rose in pressure at 10:20 pm and exploded 15 min later, seriously damaging the production unit, ripping apart[...]
Implosion of a styrene storage tank during truck unloading operations
At a chemical plant, a styrene tank "imploded" causing the release of approx. 3 tonnes of styrene product. On the day of the accident, the (44-m³) tank was being filled via a tanker truck when the driver noticed that the[...]
Explosion in a pharmaceutical factory
In a chemical plant, an explosion occurred when a glyoxylic acid production line using the ozonisation technique was re-started. The facility was destroyed a year ago by an explosion followed by a fire (ARIA 25337). The internal emergency plan and the[...]
Pollution of a river
Analyses carried out on the residual water at the discharge point of a waste water treatment plant at a chemical plant manufacturing a basic organic product revealed that the thresholds of the standards stipulated by prefectural order had been significantly[...]
Explosion followed by a fire in a laboratory
At a chemical facility, an explosion and fire occurred around 5 pm inside a laboratory on the first floor of a 4-storey, 400-m² building. The personnel were evacuated and the internal emergency plan activated. Air samples extracted from the premises[...]
Flare pipe leak on a butadiene worshop reboiler
A butadiene leak occurred inside a chemical plant; its origin was a flare pipe break on a butadiene workshop reboiler. The gas alarm was immediately activated as was the internal emergency plan. 7 tonnes of butadiene escaped, a vehicle crossing[...]
