On July 4, four people died in a poisoning accident at the Tangerine Garden Liangguo factory in Fengjiang town, Jiexi County, Jieyang Province. The Guangdong Provincial Safety Committee office put up a sign to supervise the investigation and handling of the accident.

At noon on July 4, a hydrogen sulfide gas leak occurred during the shutdown of the orange garden food 2023 in Jiexi County, causing accidental poisoning and asphyxiation. After the accident, the province, City and county attach great importance to the accident investigation team was quickly set up to carry out an investigation.

After preliminary investigation, hydrogen sulfide gas leaked from a broken connection pipe between an old spray tower and the hydrolytic acidification tank and spread to the warehouse through the door next to the tank, resulting in accidental poisoning and asphyxiation of a person in the warehouse, in the rescue process, due to the lack of rescue knowledge, and 5 rescue workers were poisoned. The final accident led to 4 deaths of hydrogen sulfide gas poisoning asphyxiation, 2 rescue workers were sent to the hospital for observation, the current observation has been discharged. The follow-up and disposal work is still in progress.

There have been frequent accidents of dangerous chemicals recently.

Case 1

Seven people were killed and one injured in a poisoning and asphyxiation accident at the wastewater treatment plant of the furong bamboo shoot food factory in Shuanghe town, Changning County, Sichuan, Yibin Province, during a maintenance operation. On-site personnel inhaled hydrogen sulphide and other toxic and harmful gases leading to poisoning asphyxiation death.

Case 2

An employee of Henan province's Jiaozuo Pitong Noodles Co. , Ltd. died after falling into a container while working and inhaling sulfur dioxide or hydrogen sulfide. Five other employees also died from the poisoning after improperly handling the rescue, six people died in the accident.

Hydrogen sulfide has a colorless, strong rotten egg odor characteristics. It is heavier than air and tends to accumulate in low-lying areas.

So how can we prevent hydrogen sulfide poisoning in the end in safe production?

In addition to identifying key protection areas and key protection operations for hydrogen sulphide, fixed hydrogen sulphide detection alarms should be installed in workplaces where hydrogen sulphide leakage may occur, indicating that the alarm panel should be located in the control room, the number and position of hydrogen sulfide detection probe on site shall be arranged in accordance with relevant specifications.

Fixed reflection laser gas telemeter

The fixed reflection laser gas telemeter of hanhai optoelectronic transceivers and transceivers as a whole, with a detection distance of up to 1 km. Different from the traditional passive waiting mode, the active detection of leakage risk points. Response time is only 1 second, can accurately detect ppm micro-leakage. To realize the preventive monitoring of gas leakage. Compared with the traditional detector, it is easy to be interfered by environment and cross gas. Fingerprint detection, truly achieve zero false positives. The product need not adjust, but can save the operation cost in the whole life cycle. In addition to hydrogen sulfide, but also detect methane, ethylene, acetylene, carbon monoxide, carbon dioxide, ammonia and other gases. Comply with national GB/T 50493-2019 standard.
