In the media before, we should have a basic understanding of the septic tank gas poisoning accident that occurred in a pig farm in Lichun Town, Pengzhou City, Sichuan Province. At that time, 7 people fell into the septic tank, although they were rescued by the rescue team formed by relevant departments at the first time, but 4 people died after on-site rescue, and 3 people were sent to the hospital for treatment and died.
After the accident, a reporter learned about the surrounding residents, saying that the pig farm had a new boss just now, and it had not been officially put into full production, and the accident occurred when making preparations before the official production. At that time, it should have been the boss who accidentally fell into the septic tank, and the other 6 people went to the rescue, but unfortunately these 6 people were poisoned and died together with the boss.
Risk factors for septic tanks
As an important facility for the treatment of livestock and poultry manure in the farm, the septic tank has a complex internal environment and conditions, and there are many risk factors, such as:
High concentration of toxic and harmful gases: Due to the sedimentation and fermentation process of sludge, a large number of toxic and harmful gases such as biogas, carbon dioxide, and hydrogen sulfide will be produced inside the septic tank. The concentrations of these gases can be very high, and once in the septic tank, people are prone to poisoning due to inhalation of these gases. In an accident, an employee may lose consciousness or even die suddenly due to inhaling too many harmful gases.
Risk of hypoxic asphyxia: Septic tanks are a relatively closed environment with poor air circulation. Due to the high specific gravity of gases such as biogas, they can occupy the upper space of the septic tank, resulting in a decrease in oxygen content. If a person enters the septic tank without proper protection, they may suffocate due to lack of oxygen.
Flammable and explosive risk: Biogas in septic tanks is a flammable and explosive gas. If the concentration of biogas reaches a certain level, it is easy to cause an explosion when it encounters an open flame or electric spark. In addition, fires or explosions can also be caused by sparks when painting, spraying, and using flammable and explosive solvents in septic tanks.
Other safety risks: In addition to the above risk factors, septic tanks may also have risks such as collapse and falling, and the spread of germs. If the structure of a septic tank is not stable or not properly maintained, it can collapse and cause injury to personnel. At the same time, the feces in the septic tank can carry a large number of germs, which, if not properly handled, can lead to the spread of germs and cause diseases. According to media reports, the poisoning accident that occurred at the farm in Pengzhou, Sichuan, was caused by the boss going to inspect the wooden plank that he was stepping on broke and fell.
Key points for the daily maintenance of septic tanks
The daily maintenance of the farm's septic tank is essential to ensure its proper operation, prevent environmental pollution and reduce the occurrence of accidents.
First of all, it should be cleaned and inspected regularly. This is the basis for ensuring the proper functioning of the septic tank. Septic tanks need to be cleaned regularly to remove accumulated feces and waste and prevent clogging and gas build-up. At the same time, the structure and equipment of the septic tank should be regularly inspected to ensure its integrity and safety.
Secondly, it is necessary to carry out regular equipment maintenance and overhaul. The equipment in the septic tank, such as agitators, pumps, etc., requires regular maintenance and overhaul to ensure its proper functioning. This not only improves the efficiency of septic tank treatment, but also prevents accidents caused by equipment failure.
In addition, pay attention to gas monitoring and ventilation. Toxic and harmful gases such as biogas may accumulate inside the septic tank, so when cleaning and maintaining, gas monitoring must be carried out, and appropriate ventilation measures must be taken to ensure air circulation and prevent poisoning accidents.
In addition, records management and security training need to be strengthened. Maintenance activities such as cleaning, inspection, and repair of septic tanks should be recorded in detail to facilitate tracking and problem detection. At the same time, regular safety training for maintenance personnel to improve their safety awareness and operation skills is also an important means to reduce accidents.
What to do if someone falls into a septic tank?
If someone falls into a septic tank, rescue efforts need to be carried out quickly and carefully. Here are some of the key rescue steps:
Call for help immediately: Call for help loudly as soon as possible, so that the surrounding people can quickly know the situation and rush to help. At the same time, call the police on 110 and ask for police rescue.
Find rescue tools: Look for ladders, sticks, or other tools that can reach into the pool as soon as possible so that the trapped person can grab and try to save themselves.
Keep yourself safe: It's important to keep yourself safe during a rescue. Never recklessly jump into the pool for rescue when safety cannot be ensured.
Prevent sinking and keep breathing: While waiting for rescue, trapped people should try to find fixities at the edge of the pool, such as pipes or edges, to prevent further sinking. At the same time, the dirt around the mouth and nose should be removed as soon as possible to keep the respiratory tract open, and the breathing rhythm should be controlled to reduce the amount of harmful gases inhaled.
Implement first aid measures: Once the trapped person is rescued, their physical condition should be assessed immediately. If necessary, immediately administer first aid measures such as artificial respiration or cardiopulmonary resuscitation, and quickly call 120 for professional medical assistance.
In addition, it should be noted that the internal environment of the septic tank is complex and dangerous, and there may be toxic gases and biogas, so it is important to take protective measures during the rescue process, such as wearing gas masks and protective clothing. At the same time, for those who are not familiar with the structure of the septic tank and rescue skills, do not rescue by themselves to avoid secondary accidents.
