The Pabour accident in India

Bhopal is the capital of Madhya Pradesh in India. On December 3, 1984, it was here that a severe gas leak occurred at a pesticide factory operated by the American multinational company Union Carbide, causing immense disaster for the local residents and shocking the world. I. The Night of Death At midnight on December 2, the pressure in a gas storage tank at the pesticide plant of Union Carbide in the suburbs of Bhopal rose sharply. The 45 tons of liquid, highly toxic methyl isocyanate stored in the tank is a raw material used in the production of the pesticides carbofuran and aldicarb. At 00:56 on the 3rd, the valve of the gas storage tank failed, causing the highly toxic chemicals inside to leak out and spread rapidly outward in gaseous form. An hour later, a thick haze of poisonous gas covered the entire city. 　　The toxic gases leaked from the pesticide factory crossed the factory walls and first reached the adjacent slums, causing hundreds of residents to die while they were asleep. There are many beggars huddled together near the train station because they are cold. The poison gas spread there, and within a few minutes, more than a dozen people died while over 200 others suffered from severe poisoning symptoms. The poison gas swept through temples, shops, streets, and lakes, covering an area of 25 square miles in the urban district. There was no wind that night, and a thick fog filled the air, allowing the poison gas to continue spreading slowly at high concentrations, spreading death. 　　A few hundred meters away from the pesticide factory, a farmer heard a dull humming sound in the vicinity, thinking it was the noise made by cows while chewing cud. He got up and went outside to check, only to find two cows dead on the ground. The other one was crying in pain, and before long it too fell at his feet. At this point, his eyes also began to hurt. Later, in the hospital, with his eyes tightly closed and tears streaming down his face, he told people, “I thought a plague had broken out.” ” 　　Many people thought the city had been attacked by an alien force or that a major earthquake had occurred, lamenting that the end of the world had arrived. Later, when people learned that it was the factory that was releasing toxic gases, they fled in panic. People fled in cars, pulling wooden carts, and riding bicycles, each going as fast as they could. Yet, the poison gas was merciless; many people lost their eyesight while trying to flee, collapsed by the side of the road, and were unable to get up again. On the streets and roads, cows, dogs, and other livestock struggle in pain. 　　After just a few nights, 2,500 people lost their lives, and another 3,000 or so were on the verge of death. 125,000 people were poisoned to varying degrees, and it is estimated that 100,000 will be disabled for life. II. The Terrifying City On the morning following the accident, Bhopal seemed to have been attacked by a missile. The houses were intact, but there were corpses of people and animals everywhere. A once-normal city turned into a city of terror. 　　It was found that on a street in the city, at least 200 people died, with more than half of them being children; those who were thin and underdeveloped became the most vulnerable victims of the toxic gases. 　　Many of the dead were discovered only after the authorities ordered the doors of the residents’ homes to be forced open. People were fast asleep when the poison gas hit them; they passed away in their dreams. Some people, upon realizing that strange gases were entering, closed their doors and windows tightly in the belief that this would protect them from those harmful gases; as a result, their homes turned into gas chambers, and hundreds of people died in this way. 　　On the streets, corpses lay next to one another. Those who are blind in both eyes, you hold me and I hold you, screaming in panic, not knowing where safety lies. 　　A large number of animals lay sprawled on the streets with swollen bellies. Plants are also not immune to the grasp of death. The leaves were trembling. The leaves of the radishes and spinach are covered with yellow spots and a layer of white film. The color of the lake changed as well, becoming murky. 　　The smell of decaying bodies hung in the air, mixing with the smoke coming from the crematorium, creating a nauseating atmosphere. 　　The grave digger was digging a long grave pit ； Tailors are sewing shrouds ； Medical staff are doing their best to prevent the outbreak of plague. 　　The entire city mourned for those victims of the poison gas. Most of the victims live in poverty and lack education. They never managed to figure out what exactly had happened in their low, mud-covered houses, nor which pesticide factory had released some monstrous creature. Many people don’t even know what poison gas is. Before the disaster struck, they had only heard that it was a factory that produced medicines, and they could not imagine any connection between medicines and poison gas. 　　At the crematorium, bodies are piled up and burned together. This goes against Hindu customs*, but since no enough wood could be found, there was no other choice. The women cried and cursed at the same time. 　　At the new Muslim graves, packs of wild dogs dug up the shallow graves and dragged out human corpses, fighting over them and biting each other. A father tried to drive a group of dogs away from his 4-year-old son’s grave, but they came back. How could those wild dogs know that by eating those dead bodies, they would themselves meet a fatal end? III. Fighting Death Hamidi Hospital is the largest hospital in Bhopal city. Just a few hours after the gas leak, hundreds of victims with poisoning symptoms formed long queues in the hospitals. At the same time, **small cars keep coming here, carrying mostly children and the elderly. The 350 doctors and 1,000 nurses in the hospital had already been fully mobilized, yet they still couldn’t take care of all the patients who kept arriving. In the end, 500 medical students had to be assigned to the medical teams. All 750 hospital beds were occupied by patients with poisoning. The open areas around the hospital were filled with patients, their moans, coughs, and sobs creating a cacophony of sound. 　　Many patients collapse as soon as they arrive at the hospital, as if they have reached the final stage of their life journey. They were completely exhausted, just like warriors who had just fought a fierce battle. After some waiting, they usually receive careful care from doctors and nurses. The military was also mobilized; their task was to maintain order among the crowds and prevent overcrowding and collisions. They set up twenty tents near the hospital as temporary wards, with each tent capable of holding twenty people. They also set up morgues, where the unclaimed dead were gathered together waiting for their relatives to claim them. If no one claims them in the end, they burn Hindus and bury Muslims. 　　The university hospital in Bhopal is also carrying out urgent rescue efforts. As soon as the accident occurred, seven children aged one to seven were taken to the emergency room. In their hospital beds, the children were very irritable, coughing and vomiting non-stop, with their mouths wide open as they breathed heavily. The parents and relatives watched as the doctor treated the children, and the doctor said to them in a soft voice, “The children’s chances of surviving are only 50 percent.” ”Four hundred and fifty doctors at the university hospital saved the lives of thousands of people over the two days of December 3rd and 4th. 　　There are five hospitals in the city. All hospitals are overcrowded. Volunteer organizations help care for patients and comfort those who are in shock everywhere. One doctor said, “We were terrified, thinking they would all die here.” Because when they first arrived, it seemed like they were about to stop breathing. ” 　　This methyl isocyanate, which poisoned the city of Bhopal, along with the \"Phosgene\" gas used by the German army during World War I, are collectively referred to as the two most deadly poisonous gases. The medical authorities in Bhopal are very concerned about the possible long-term effects of the poison gas. Doctors believe that the survivors of this incident will develop emphysema, asthma, and bronchitis. Some experts point out that the damage caused by poison gas to the liver and kidneys may be more severe. A doctor at Hamidi Hospital said, “Poison gas affects the central nervous system, which can cause lifelong impairment in many patients.” ”On the day after the incident, several cases of abdominal pain in pregnant women occurred. Upon examination by the doctor, the fetus was dead inside the womb. 　　News of the accident was reported to Prime Minister Rajiv Gandhi, who promptly halted his campaign tour in northern India, rushed to Bhopal to inspect the situation, and allocated four million dollars to assist the victims. Madhya Pradesh **also provides relief to each family that has suffered damage. 　　The dead cannot be brought back to life, and the injured may have to live with disabilities for the rest of their lives. What lessons will people draw from this worst disaster of the post-war era? IV. Where are the lessons? 　　After the Bhopal disaster, news spread quickly, and the world was **in shock**. Many newspapers and magazines published articles criticizing United Carbon Corporation, pointing out that its factory in India and its factory in West Virginia, USA, applied a \"double standard\" when it came to environmental safety measures, with two different levels of protection; the Bhopal pesticide factory only had basic safety equipment ； In addition, the factories located in the United States are also equipped with computer-based alarm systems. Furthermore, the location of this factory in India is in a densely populated area, whereas the similar factory in the United States is located far away from densely populated areas. As an environmental protection activist from a third-world country put it well: \"Multinational companies often establish their more hazardous factories in developing countries in order to avoid the strict regulations they are required to comply with in their home countries.\" Now this has become an issue with a clear bias. ” 　　Prime Minister La Gandhi, on behalf of India, **demanded that United Carbides compensate for the losses, and declared firmly that India **would no longer allow the production of any hazardous substances in densely populated areas. 　　The American law firm Melvin Belli, along with two other firms, filed a lawsuit on behalf of Indian victims, seeking $15 billion in compensation from Union Carbide Corporation. The lawsuit accuses the multinational company of errors in both the design and operation of the plant, which led to the release of toxic gases and resulted in a mass death toll in that industrial accident. 　　United Carbide Corporation is a multinational company that ranks thirty-seventh among all large companies in the United States. It has subsidiaries in 38 countries around the world, engages in the production of a variety of products, employs one hundred thousand people, and has assets worth ten billion dollars. Following the gas leak at the Bhopal pesticide plant, the value of each share of the company’s stock dropped by ten dollars, resulting in a total loss of $440 million in stock value. Some experts predict that United Carbide will find it difficult to survive without turning to federal bankruptcy laws. 　　The poisonous gas that caused harm for a time has dissipated, and the last fires that burned the victims have also gone out. The highly toxic gas in the other gas tank has also been neutralized through appropriate measures, becoming non-toxic. The residents of Bhopal who had fled are gradually returning home. But the wounds left by the Bhopal disaster will continue to cause pain in people’s hearts for a long time. It is hoped that the Bhopal tragedy, which occurred amid the current unreasonable state of the world economic order, will provide an opportunity for everyone to draw thorough lessons from it.

It can be used as a teaching material. The waking effect is quite strong

Hearing it for the first time – a tragedy in human history. It would be great if there were a gas alarm. How did no one in the factory notice it at that time?

The 1984 Bhopal disaster in India, which resulted in 3,000 deaths, was the worst industrial accident in human history. This accident reminds us that our country is in a stage of accelerated industrial development, with increasing production concentration, which raises the likelihood of severe accidents that result in many deaths and injuries. Therefore, preventing such serious accidents is the top priority at present. At the same time, it is necessary to stop the mass relocation of low-end industries from abroad to the Chinese mainland, as this would consume our energy resources, cause pollution, and even lead to loss of lives. Therefore, we must learn from the lessons of this accident to prevent repeating the same mistakes.

It can be said that the Indian \"Pabore\" incident has always been a typical case of a major safety accident in a chemical industry company. This case illustrates the **importance of implementing safety standardization!** For chemical companies, the most important thing is that they must not be built in densely populated areas. Another point is that when bringing foreign companies to the Chinese mainland, it is necessary to strictly oversee their safety facilities, while also introducing their advanced technologies and management practices. This case tells us a great deal: dense population near chemical plants, insufficient safety distances, automatic monitoring and alarm systems for toxic gases, emergency response plans, safety interlocks, risk assessment, and so on!

Actually, when formulating emergency plans, one of the requirements is to inform nearby residents and factories about the company’s hazard sources, the MSDS information for those hazardous substances, as well as the procedures to follow in case of an emergency. It seems that some companies fail to inform the relevant departments, nearby companies, and residents when activating the emergency response plan in case of abnormal situations. These are social responsibilities, as well as the conscience of us as security personnel.

Developed countries generally do not allow chemical companies to produce highly toxic chemicals within their own borders; and even if such production is permitted, strict requirements are imposed, and the investment in safety facilities is extremely high. Driven by profit, these multinational companies carry out production in underdeveloped areas with minimal investment in safety and environmental protection, ignoring the consequences of any accidents. While reaping huge profits, they leave behind irreversible pollution in those regions. We should be aware of this invisible form of exploitation by imperialism.

Learn from the mistakes of others, and carry out proper safety and environmental impact assessments in a genuine manner, rather than just going through the motions. Safety management, safety technologies, and safety measures cannot be overlooked; when introducing production technologies and equipment, do not forget the accompanying safety and environmental protection technologies as well.

These accident cases have been used in teaching for a long time; the main reason is the lack of safety knowledge, and it is also a typical example of the United States relocating companies with excessive risks to underdeveloped areas. Different safety standards were adopted in the United States and India, coupled with poor personnel quality and the incident occurring at night, which led to an astonishing number of deaths. A profound lesson!

The wisdom of others can be used to improve one’s own performance; by learning from the mistakes of others, it is possible to identify and address potential hazards, thereby enhancing the intrinsic safety of equipment and facilities. Safety education should be carried out through various means and channels.

There are several points to take note of in the future: 1: Process design safety – this tank is not necessary from a process perspective. 2: Change the cleaning medium; water reacts with methyl isocyanate. 3: Optimize the process so that only small amounts of methyl isocyanate are present, which then go directly into the next reaction step. 4: Keep it away from people; the factory should be relocated once there are more people living in the surrounding area.

　The Pabour accident in India is a typical example. Pabore United Carbonization Company is an insecticide manufacturing enterprise funded by developed countries. On December 3, 1984, a severe gas leak occurred, which not only caused serious damage to the local environment but also led to the death of over 6,000 people and affected 200,000 others; to this day, thousands of people remain at risk of illness and death. 　　Some developed countries take advantage of the desire in certain regions of our country to attract foreign investment, and actively transfer dirty industries to China. In 1991, foreign investors established 11,515 manufacturing enterprises in our country, with agreed-upon investment amounts of 8.771 billion US dollars. Among these were 3,253 enterprises that were pollution-intensive, accounting for 29.12% of the total; the actual investment amount for these enterprises was 3.227 billion US dollars, representing 36.8% of the total investment. For **ecological security, we must resolutely resist such practices and keep dirty industries out of our country.
