At 11.40 am., a release of 200 kg formaldehyde solution occurred in a storage tank facility for the production of synthetic resins, leading to the death of a large quantity of fish on 15 km in the receiving water-course and the damage of the communal sewage treatment plant was.

An employee smelled a strong odour and the leak was discovered in condensates. The on-site fire-brigade intercepted (collected) the released formaldehyde solution in a retention pond and then closed the line of condensate with a gate (stopper, slide). All valves for the heating of the raw material tank were shut down electrically. A defect in the vapour heating of one tank is the cause of the accident. The damage to the WWTP were evaluated at 20 000 euros and the damage to the environment at 25 000 euros.
