Abstract
On a fattening pig farm all 582 animals died of peracute intoxication with hydrogen sulphide (H2S). The accident took place after 6000 litres of lactic acid (41.5 mass %) was dumped in the slurry pit. The volume of released gas was about 575 m3. This resulted in sudden spreading by high pressure of a lethal concentration of hydrogen sulphide to all compartments of the pig house. Analysis of the situation indicated that the level of hydrogen sulphide was 7870 ppm.
摘要
在一个育肥猪场，所有582头猪死于硫化氢（H₂S）引起的急性中毒。事故发生在将6000升乳酸（质量分数41.5%）倾倒到粪坑之后。释放的气体体积约为575立方米。这导致致死浓度的硫化氢在高压下突然扩散到猪舍的所有隔间。对情况的分析表明，硫化氢水平为7870 ppm。
