Is the hot spring raw water poisonous?

It is reported that recently, a man and a woman fell into the water and died in a flood drainage ditch outside Mianzhou Hot Spring Hotel in Anzhou District, Mianyang. After the rescue, the man died and the woman was seriously injured. Later, it was confirmed that they were poisoned by directly inhaling toxic gas from hot spring raw water.

According to the report, the local people rushed to the scene immediately after receiving the alarm from the masses, but the parties eventually died after being rescued. As can be seen from a photo provided by the relevant person in charge, there were 120 medical staff on the scene at the time of the incident. Recently, the police informed Mr. Li's family about the case.

According to industry insiders, the hot spring raw water of general hot spring hotels is derived from water supply stations. When the hotel needs raw water, it calls the water supply station, which opens the valve and pumps the hot spring raw water into the reservoir of the hotel through a closed pipeline. When the reservoir is full, the water supply station can close the valve, and employees can also close the valve of the reservoir themselves.

In order to ensure the safety of customers soaking in hot springs, the water distributor of hot spring hotel will distribute tap water and hot spring raw water according to a certain proportion, thus diluting the hot spring raw water. Otherwise, the gas in the hot spring raw water will come out of the sealed pipeline, and the poisonous gas will rise directly. If it is inhaled carelessly, it may lead to human poisoning.

Experts said that there is currently no regulatory standard for hot spring raw water. Under normal circumstances, hot spring raw water will not cause poisoning and is not a high-risk hazardous chemical. How to regulate it reasonably needs to be explored, and the state is also formulating relevant standards.
