The materials in the cabin of the fishing boat are easy to deteriorate, a large amount of hydrogen sulfide is generated, the hydrogen sulfide is flammable and toxic gas, and people are easy to be poisoned if the materials are not evacuated in time. For example: in 2016, 5 and 8 days, fish and shrimp in Fujian Shi 06351 ship are rotten due to hot weather, and 4 fishermen fall down one after another by the generated harmful gas. 28 days 11 and 28 months 2015, 4 fishermen on the fishing boat with Zhe Shi fisher 10013 suddenly suffer from hydrogen sulfide poisoning, wherein two fishermen suffering from poisoning fall into a syncope state. In 2015, in 5 months, fish and goods of the stone lion-fishing boat are decayed to generate H2S, so that 4 fishermen are poisoned, and the captain and captain of the boat are rescued and do not effectively die. According to statistics, in recent years, only the coastal fishing vessel of Taizhou generates H on average every year2The poisoning event of S is more than 40, and 35 ship crew die. The same kind of unfortunate poisoning accidents occur almost every year in Shandong, Fujian, Zhejiang, etc. H2S poisoning incidents become a safety problem which cannot be ignored in coastal fishing areas, seriously threaten the life and property safety of fishermen, and have attracted high attention of relevant management departments. Therefore, it is necessary to provide ventilation equipment in the tank to ventilate the tank when the hydrogen sulfide concentration in the tank exceeds a standard. However, when the ventilation device is installed, the ventilation device is not opened in time due to negligence of a crew, so that the ventilation device is nominal, and the occurrence of tragedy in hydrogen sulfide cannot be avoided.
