Union Carbide Disaster in Bhopal - India The impact(s) of this incident. The Union Carbide Catastrophe is one of the world’s devastating and life-threatening events, which have claimed for many lives of people and it is reported that it continues to today. Based on the play, the Union Carbide Catastrophe is a 33 years incident that happened in Bhopal India on 4th December 1984; released nearly 40 tons of highly toxic gas or poisonous gases known as methyl isocyanate. According to the play, at the time, the Union Carbide disaster was reported the worst and dangerous industrial accident in the world’s history. The gas escaped and hit over the densely populated neighboring towns of the plants, and killed over 15, 000 people instantly and half…

Bhopal India 1984 On the night of the 2nd of December 1984 tragedy struck in Bhopal, India killing an estimated 20,000 people. It began with a pesticide plant by Union Carbide. Union Carbide had diversified into India via Union Carbide India Limited. They had suspected that India was an enormous market that was yet to be tapped into and discovered. At the time UCC was one of the first companies to invest into India (Union Carbide Corporations). The plan was to sell their pesticide “Sevin” to…

2.1 Silicon-Carbide (SiC) Initially, Silicon carbide (SiC) was accidentally introduced by Edward G. Acheson in 1890. Silicon Carbide can be stated as a chemical compound of Silicon and the carbon. Edward G. Acheson was running an experiment on the synthesis of diamonds. At that time, it was produced by a high temperature electro chemical reaction of sand and carbon. We can also find the silicon carbide very rarely in nature in very small amounts. Also Edward G. Acheson was the first person to…

Silicon carbide has been recognised as an important structural ceramic material because of its unique combination of properties. It is a promising ceramic material that can replace conventional metals and ionic-bonded oxide ceramics such as alumina. Structure of Silicon carbide Silicon carbide is a compound of silicon, a metalloid, and carbon, a nonmetal, and has a giant molecular lattice structure. It has a similar structure with diamond. Each carbon atom is joined tetrahedrally to four…

Lattice Dynamics 2.1 Introduction The discussion has been done in chapter1 about the nature crystal structure of Silicon Carbide and its properties was under the equilibrium condition, which means the location of each atom is restricted at its lattice site. The vibration of atoms about their equilibrium sites will be considered in this chapter. The fundamental reason of this vibration is thermal and the lowest achievable energy (i.e. zero-point energy). The forces acting on atoms tend to always…

The explosion of the Union Carbide India Limited pesticide plant in Bhopal, India on December 2, 1984 will remain one of the worst industrial calamities the world has seen. The official death count at the time of the incident was nearly 3000 deaths, but unofficial estimates hovered between 8000 – 10000 deaths (Bogart, 1989). This multifaceted case presents a unique challenge to critique the ethical dilemma in regards to Union Carbide’s legal strategy in response to the situation. The purpose…

Repercussions for engineers working for Union Carbide in Bhopal and consequences for Union Carbide following Bhopal disaster. In 3 December 1984 there was a gas tragedy in Bhopal, the capital of the Indian state of Madhya Pradesh. People around the city were in chaotic motion all trying to escape the toxic gas cloud that resulted from the gas leakage from the plant owned by the Union Carbide Corporation that its aim was to produce Methyl Isocyanate, toxic constituent of pesticide Sevin. It was…

Koutsomichalis et al (2008) discussed that having high hardness and good adhesion with the substrate the sprayed coating exhibited satisfactory wear resistance. Tungsten carbide is an advanced ceramic material combining a unique set of properties such as high hardness, high melting point, wear resistance, good thermal shock resistance, thermal conductivity and good resistance against oxidation. They can be applied as coatings by thermal spraying processes such as plasma-spraying, high-velocity…

In 1984 on the night of the second of December the Bhopal plant emitted 42 tonnes of methyl isocyanate gas exposing to more than 500,000 people and killing around 5,000 people. The clean-up of this disaster was insufficient and people are still being affected by the leakage. Methyl isocyanate gas also known as MIC is a clear liquid used to make pesticides, when exposed to the gas it brings the same effects as tear gas. Some of the effects that people went through were swelling and burning of…

population slept during the night of December 3, 1984, a toxic cloud of over forty tons of methyl isocyanate (MIC) gas escaped from the Union Carbide plant in Bhopal, central India. Heavier than air, the gas blanketed the slums surrounding the facility and spread over the city of 800,000 people. At least 2,000 died immediately, although local estimates run into the tens of thousands.” (Ethics and Business: An Introduction, Kevin Gibson, 2007, page 1) This situation had a lot of harmful effects…
