“WHAT IS BHOPAL GAS TRAGEDY ?”
 The Bhopal gas tragedy (commonly referred
  to as Bhopal disaster) was a gas leak incident
  in India, considered one of the world's worst
  industrial catastrophes.
 It occurred on the night of 2nd–3rd December
  1984 at the Union Carbide India Limited (UCIL)
  pesticide plant in Bhopal, Madhya Pradesh.
 A leak of methyl isocyanate (MIC) gas and
  other chemicals from the plant resulted in the
  exposure of hundreds of thousands of people.
BACKGROUND OF “UCIL”
 UCIL, built in 1969, which was the Indian
  subsidiary of Union Carbide Corporation
  (UCC), with Indian Government controlled
  banks and the Indian public holding a 49.1%
  stake.
 In 1994, the Supreme Court of India allowed
  UCC to sell its 50.9% share. Union Carbide sold
  UCIL, the Bhopal plant operator, to Eveready
  Industries India Limited in 1994.
 The Bhopal plant was later sold to McLeod
  Russel     (India)   Ltd.    Dow     Chemical
  Company purchased UCC in 2001.
PLANT PRODUCTION PROCESS

   The UCIL factory was built to produce the
    pesticide Sevin (UCC's brand name
    for carbaryl) using methyl isocyanate (MIC)
    as an intermediate.

                               Methylamine (1) reacts
                               with phosgene (2)
                               producing methyl
                               isocyanate (3) which
                               reacts with 1-
                               naphthol (4) to yield
                               carbaryl (5)
THE ACCIDENT

 During the night of 2–3 December 1984,
  water entered Tank E610 containing 42 tons
  of MIC.
 The resulting exothermic reaction increased
  the temperature inside the tank to
  over    200°C (392 °F) and raised the
  pressure.
 About 30 metric tons of methyl isocyanate
  (MIC) escaped from the tank into the
  atmosphere of Bhopal in 45 to 60 minutes.
FACTORS LEADING TO THE GAS LEAK
 Storing MIC in large tanks and filling beyond
  recommended levels,
 Poor maintenance,
 Failure of several safety systems,
 Safety systems being switched off to save
  money—including the MIC tank refrigeration
  system which could have mitigated the disaster
  severity,
 Plant location close to a densely populated
  area,
 Undersized safety devices,
 The dependence on manual operations,
   Plant management deficiencies were also identified –
       lack of skilled operators,
       reduction of safety management,
       insufficient maintenance,
       inadequate emergency action plans.
   Use of a more dangerous pesticide manufacturing
    method, or ―ROUTE‖, where same raw materials are
    combined in a different manufacturing order, with
    phosgene first reacted with naphthol to form a
    chloroformate ester, which is then reacted with methyl
    amine.
   In the early 1980s, the demand for pesticides had
    fallen, but production continued, leading to buildup of
    stores of unused MIC

DUMPING OF HAZARDOUS MATERIAL
THE DEVASTATION
 The official immediate death toll was 2,259 and
  the government of Madhya Pradesh has
  confirmed a total of 3,787 deaths related to the
  gas release.
 Others estimate 8,000 died within two weeks and
  another 8,000 or more have since died from gas-
  related diseases.
 A government affidavit in 2006 stated the leak
  caused 5,58,125 injuries including 38,478
  temporary partial and approximately 3,900
  severely and permanently disabling injuries.
 2,000 bloated animal carcasses had to be
  disposed.
HEALTH EFFECTS
   Short term health effects
       Apart from MIC, the dense gas cloud may have
        contained
          phosgene,
          hydrogen  cyanide,
          carbon monoxide,
          hydrogen chloride,
          oxides of nitrogen,
          monomethyl amine (MMA) and
          carbon dioxide, either produced in the storage tank or in the
           atmosphere.
       The initial effects of exposure were coughing,
        vomiting, severe eye irritation and a feeling of
        suffocation.
   The acute symptoms were burning in the
    respiratory tract and eyes, blepharospasm,
    breathlessness, stomach pains and vomiting.
   The     causes      of   deaths    were   choking,
    reflexogenic circulatory collapse and pulmonary
    oedema.
   Findings during autopsies revealed changes not
    only in the lungs but also cerebral oedema, tubular
    necrosis of the kidneys, fatty degeneration of the
    liver and necrotising enteritis.
   The stillbirth rate increased by up to 300%
    and neonatal mortality rate by 200%.
LONG TERM HEALTH EFFECTS
 It is estimated 100,000 to 200,000 people have
  permanent injuries.
 Reported symptoms are
     eye problems,
     respiratory difficulties,
     immune and neurological disorders,
     cardiac failure secondary to lung injury,
     female reproductive difficulties and
     birth defects among children born to affected
      women.
   The Indian Government and UCC deny
    permanent injuries were caused by MIC or the
    other gases.
AFTERMATH OF THE LEAKAGE
 Medical staff were unprepared for the thousands
  of casualties.
 Doctors and hospitals were not informed of
  proper treatment methods for MIC gas
  inhalation. They were told to simply give cough
  medicine and eye drops to their patients.[
 The gases immediately caused visible damage
  to the trees. Within a few days, all the leaves fell
  off.
 "Operation Faith": On 16 December, the tanks
  611 and 619 were emptied of the remaining
  MIC. This led to a second mass evacuation from
 Formal statements were issued that air, water,
  vegetation and foodstuffs were safe within the
  city. At the same time, people were informed
  that poultry was unaffected, but were warned
  not to consume fish.
 A total of 36 wards were marked by the
  authorities as being "gas affected", affecting a
  population of 520,000.
 Of these, 200,000 were below 15 years of age,
  and 3,000 were pregnant women.
 There     were mass funerals and mass
  cremations. Bodies were dumped into the
  Narmada River, less than 100 km from Bhopal.
COMPENSATION FROM UNION CARBIDE
 The Government of India passed the Bhopal
  Gas Leak Disaster Act that gave the
  government rights to represent all victims in
  or outside India.
 UCC offered US $350 million, the insurance
  sum. The Government of India claimed
  US$ 3.3 billion from UCC.
 In 1989, a settlement was reached under
  which UCC agreed to pay US$470
  million (the insurance sum, plus interest) in
  a full and final settlement of its civil and
  criminal liability.
 When UCC wanted to sell its shares in UCIL, it
  was directed by the Supreme Court to finance a
  500-bed hospital for the medical care of the
  survivors. Bhopal Memorial Hospital and
  Research Centre (BMHRC) was inaugurated in
  1998. It was obliged to give free care for
  survivors for eight years.
 A US court rejected the law suit blaming UCC
  for causing soil and water pollution around the
  site of the plant and ruled that responsibility for
  remedial measures or related claims rested with
  the State Government and not with UCC.
ECONOMIC REHABILITATION
   Immediate relief was decided two days after the tragedy.
   Relief measures commenced in 1985 when food was
    distributed for a short period and ration cards were
    distributed.
   Madhya Pradesh government's finance department
    allocated Rs 874 million for victim relief in July 1985.
   Widow pension of Rs 200/per month (later Rs 750) was
    provided.
   One-time ex-gratia payment of Rs 1,500 to families with
    monthly income Rs 500 or less was decided.
   Each claimant was to be categorized by a doctor.
   In court, the claimants were expected to prove "beyond
    reasonable doubt" that death or injury in each case was
    attributable to exposure.
   From 1990 interim relief of Rs 200 was paid to everyone in
    the family who was born before the disaster.
   The final compensation (including interim relief) for
    personal injury was for the majority Rs 25,000 (US$ 830).
    For death claim, the average sum paid out was Rs 62,000
    (US$ 2,058).
   Effects of interim relief were more children sent to school,
    more money spent on treatment and food, and housing
    improvements.
   In 2007, 1,029,517 cases were registered and decided.
    Number of awarded cases were 574,304 and number of
    rejected cases 455,213. Total compensation awarded was
    Rs.1,546.47 crores.
   On 24 June 2010, the Union Cabinet of the Government of
    India approved a Rs1265cr aid package. It will be funded
    by Indian taxpayers through the government.
OCCUPATIONAL REHABILITATION
 33 of the 50 planned work-sheds for gas victims
  started. All except one was closed down by
  1992.
 1986, the MP government invested in the
  Special Industrial Area Bhopal. 152 of the
  planned 200 work-sheds were built. In 2000, 16
  were partially functioning.
 It is estimated that 50,000 persons need
  alternative jobs, and that less than 100 gas
  victims have found regular employment under
  the government's scheme.
HABITATION REHABILITATION

 2,486 flats in two- and four-story buildings
  were constructed in the "Widows colony"
  outside Bhopal.
 The water did not reach the upper floors.

 It was not possible to keep cattle.

 Infrastructure like buses, schools, etc. were
  missing for at least a decade.
HEALTH CARE
   In the immediate aftermath of the disaster, the health
    care system became tremendously overloaded. Within
    weeks, the State Government established a number of
    hospitals, clinics and mobile units in the gas-affected
    area.
   Radical health groups set up JSK (the People's Health
    Centre) that was working a few years from 1985.
   The Government of India has focused primarily on
    increasing the hospital-based services for gas victims.
    Several hospitals have been built after the disaster. In
    1994, there were approximately 1.25 beds per 1,000,
    compared to the recommendation from the World bank
    of 1.0 beds per 1,000 in developing countries.
   The Bhopal Memorial Hospital and Research
    Centre (BMHRC) is a 350-bedded super speciality
    hospital. Heart surgery and hemodialysis are done.
    Major specialities missing are gynecology, obstetrics
    and pediatrics.
   Eight mini-units (outreach health centers) were started.
    Free health care for gas victims should be offered until
    2006.
   Sambhavna Trust is a charitable trust that registered in
    1995.                     The                      clinic
    gives modern and Ayurvedic treatments to gas victims,
    free of charge.
   Since the leak, a very large number of private
    practitioners have opened in Bhopal. In the severely
    affected areas, nearly 70 percent do not appear to be
    professionally qualified.
ENVIRONMENTAL REHABILITATION
   When the factory was closed in 1985–1986, pipes,
    drums and tanks were sold. The MIC and the Sevin
    plants are still there, as are storages of different
    residues. Isolation material is falling down and
    spreading.
   The area around the plant was used as a dumping
    area for hazardous chemicals.
   Tubewells in the vicinity of the UCC factory had to be
    abandoned. UCC's laboratory tests in 1989 revealed
    that soil and water samples collected from near the
    factory and inside the plant were toxic to fish.
   In order to provide safe drinking water to the
    population around the UCC factory, there is a scheme
    for improvement of water supply.[43]
   In December 2008, the Madhya Pradesh High Court
    decided that the toxic waste should be incinerated
    at Ankleshwar in Gujarat.[49]
   In October 2011, the Institute of Environmental
    Management and Assessment published an article
    and video by two British environmental scientists,
    showing the current state of the plant, landfill and
    solar evaporation ponds and calling for renewed
    international efforts to provide the necessary skills to
    clean up the site and contaminated groundwater[50]

  • 2. “WHAT IS BHOPAL GAS TRAGEDY ?”  The Bhopal gas tragedy (commonly referred to as Bhopal disaster) was a gas leak incident in India, considered one of the world's worst industrial catastrophes.  It occurred on the night of 2nd–3rd December 1984 at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, Madhya Pradesh.  A leak of methyl isocyanate (MIC) gas and other chemicals from the plant resulted in the exposure of hundreds of thousands of people.
  • 3. BACKGROUND OF “UCIL”  UCIL, built in 1969, which was the Indian subsidiary of Union Carbide Corporation (UCC), with Indian Government controlled banks and the Indian public holding a 49.1% stake.  In 1994, the Supreme Court of India allowed UCC to sell its 50.9% share. Union Carbide sold UCIL, the Bhopal plant operator, to Eveready Industries India Limited in 1994.  The Bhopal plant was later sold to McLeod Russel (India) Ltd. Dow Chemical Company purchased UCC in 2001.
  • 4. PLANT PRODUCTION PROCESS  The UCIL factory was built to produce the pesticide Sevin (UCC's brand name for carbaryl) using methyl isocyanate (MIC) as an intermediate. Methylamine (1) reacts with phosgene (2) producing methyl isocyanate (3) which reacts with 1- naphthol (4) to yield carbaryl (5)
  • 5. THE ACCIDENT  During the night of 2–3 December 1984, water entered Tank E610 containing 42 tons of MIC.  The resulting exothermic reaction increased the temperature inside the tank to over 200°C (392 °F) and raised the pressure.  About 30 metric tons of methyl isocyanate (MIC) escaped from the tank into the atmosphere of Bhopal in 45 to 60 minutes.

  • 7. FACTORS LEADING TO THE GAS LEAK  Storing MIC in large tanks and filling beyond recommended levels,  Poor maintenance,  Failure of several safety systems,  Safety systems being switched off to save money—including the MIC tank refrigeration system which could have mitigated the disaster severity,  Plant location close to a densely populated area,  Undersized safety devices,  The dependence on manual operations,
  • 8. Plant management deficiencies were also identified –  lack of skilled operators,  reduction of safety management,  insufficient maintenance,  inadequate emergency action plans.  Use of a more dangerous pesticide manufacturing method, or ―ROUTE‖, where same raw materials are combined in a different manufacturing order, with phosgene first reacted with naphthol to form a chloroformate ester, which is then reacted with methyl amine.  In the early 1980s, the demand for pesticides had fallen, but production continued, leading to buildup of stores of unused MIC

  • 18. HEALTH EFFECTS  Short term health effects  Apart from MIC, the dense gas cloud may have contained  phosgene,  hydrogen cyanide,  carbon monoxide,  hydrogen chloride,  oxides of nitrogen,  monomethyl amine (MMA) and  carbon dioxide, either produced in the storage tank or in the atmosphere.  The initial effects of exposure were coughing, vomiting, severe eye irritation and a feeling of suffocation.
  • 19. The acute symptoms were burning in the respiratory tract and eyes, blepharospasm, breathlessness, stomach pains and vomiting.  The causes of deaths were choking, reflexogenic circulatory collapse and pulmonary oedema.  Findings during autopsies revealed changes not only in the lungs but also cerebral oedema, tubular necrosis of the kidneys, fatty degeneration of the liver and necrotising enteritis.  The stillbirth rate increased by up to 300% and neonatal mortality rate by 200%.

  • 25. AFTERMATH OF THE LEAKAGE  Medical staff were unprepared for the thousands of casualties.  Doctors and hospitals were not informed of proper treatment methods for MIC gas inhalation. They were told to simply give cough medicine and eye drops to their patients.[  The gases immediately caused visible damage to the trees. Within a few days, all the leaves fell off.  "Operation Faith": On 16 December, the tanks 611 and 619 were emptied of the remaining MIC. This led to a second mass evacuation from
  • 26.  Formal statements were issued that air, water, vegetation and foodstuffs were safe within the city. At the same time, people were informed that poultry was unaffected, but were warned not to consume fish.  A total of 36 wards were marked by the authorities as being "gas affected", affecting a population of 520,000.  Of these, 200,000 were below 15 years of age, and 3,000 were pregnant women.  There were mass funerals and mass cremations. Bodies were dumped into the Narmada River, less than 100 km from Bhopal.
  • 27. COMPENSATION FROM UNION CARBIDE  The Government of India passed the Bhopal Gas Leak Disaster Act that gave the government rights to represent all victims in or outside India.  UCC offered US $350 million, the insurance sum. The Government of India claimed US$ 3.3 billion from UCC.  In 1989, a settlement was reached under which UCC agreed to pay US$470 million (the insurance sum, plus interest) in a full and final settlement of its civil and criminal liability.
  • 28.  When UCC wanted to sell its shares in UCIL, it was directed by the Supreme Court to finance a 500-bed hospital for the medical care of the survivors. Bhopal Memorial Hospital and Research Centre (BMHRC) was inaugurated in 1998. It was obliged to give free care for survivors for eight years.  A US court rejected the law suit blaming UCC for causing soil and water pollution around the site of the plant and ruled that responsibility for remedial measures or related claims rested with the State Government and not with UCC.
  • 29. ECONOMIC REHABILITATION  Immediate relief was decided two days after the tragedy.  Relief measures commenced in 1985 when food was distributed for a short period and ration cards were distributed.  Madhya Pradesh government's finance department allocated Rs 874 million for victim relief in July 1985.  Widow pension of Rs 200/per month (later Rs 750) was provided.  One-time ex-gratia payment of Rs 1,500 to families with monthly income Rs 500 or less was decided.  Each claimant was to be categorized by a doctor.  In court, the claimants were expected to prove "beyond reasonable doubt" that death or injury in each case was attributable to exposure.
  • 30. From 1990 interim relief of Rs 200 was paid to everyone in the family who was born before the disaster.  The final compensation (including interim relief) for personal injury was for the majority Rs 25,000 (US$ 830). For death claim, the average sum paid out was Rs 62,000 (US$ 2,058).  Effects of interim relief were more children sent to school, more money spent on treatment and food, and housing improvements.  In 2007, 1,029,517 cases were registered and decided. Number of awarded cases were 574,304 and number of rejected cases 455,213. Total compensation awarded was Rs.1,546.47 crores.  On 24 June 2010, the Union Cabinet of the Government of India approved a Rs1265cr aid package. It will be funded by Indian taxpayers through the government.
  • 31. OCCUPATIONAL REHABILITATION  33 of the 50 planned work-sheds for gas victims started. All except one was closed down by 1992.  1986, the MP government invested in the Special Industrial Area Bhopal. 152 of the planned 200 work-sheds were built. In 2000, 16 were partially functioning.  It is estimated that 50,000 persons need alternative jobs, and that less than 100 gas victims have found regular employment under the government's scheme.
  • 32. HABITATION REHABILITATION  2,486 flats in two- and four-story buildings were constructed in the "Widows colony" outside Bhopal.  The water did not reach the upper floors.  It was not possible to keep cattle.  Infrastructure like buses, schools, etc. were missing for at least a decade.
  • 33. HEALTH CARE  In the immediate aftermath of the disaster, the health care system became tremendously overloaded. Within weeks, the State Government established a number of hospitals, clinics and mobile units in the gas-affected area.  Radical health groups set up JSK (the People's Health Centre) that was working a few years from 1985.  The Government of India has focused primarily on increasing the hospital-based services for gas victims. Several hospitals have been built after the disaster. In 1994, there were approximately 1.25 beds per 1,000, compared to the recommendation from the World bank of 1.0 beds per 1,000 in developing countries.
  • 34. The Bhopal Memorial Hospital and Research Centre (BMHRC) is a 350-bedded super speciality hospital. Heart surgery and hemodialysis are done. Major specialities missing are gynecology, obstetrics and pediatrics.  Eight mini-units (outreach health centers) were started. Free health care for gas victims should be offered until 2006.  Sambhavna Trust is a charitable trust that registered in 1995. The clinic gives modern and Ayurvedic treatments to gas victims, free of charge.  Since the leak, a very large number of private practitioners have opened in Bhopal. In the severely affected areas, nearly 70 percent do not appear to be professionally qualified.
  • 35. ENVIRONMENTAL REHABILITATION  When the factory was closed in 1985–1986, pipes, drums and tanks were sold. The MIC and the Sevin plants are still there, as are storages of different residues. Isolation material is falling down and spreading.  The area around the plant was used as a dumping area for hazardous chemicals.  Tubewells in the vicinity of the UCC factory had to be abandoned. UCC's laboratory tests in 1989 revealed that soil and water samples collected from near the factory and inside the plant were toxic to fish.
  • 36. In order to provide safe drinking water to the population around the UCC factory, there is a scheme for improvement of water supply.[43]  In December 2008, the Madhya Pradesh High Court decided that the toxic waste should be incinerated at Ankleshwar in Gujarat.[49]  In October 2011, the Institute of Environmental Management and Assessment published an article and video by two British environmental scientists, showing the current state of the plant, landfill and solar evaporation ponds and calling for renewed international efforts to provide the necessary skills to clean up the site and contaminated groundwater[50]
