Description of Ladbroke Grove Rail Crash The Ladbroke Grove rail crash is termed as one the worst rail accidents that have ever occurred in Britain (Kletz. 2002). The accident occurred on the 5th of March in 1999 at the Ladbroke Grove. On this day, 5th of March 1999, at exactly 08:06 British Summer Time, a Thames Trains service departed from Paddington station, platform nine and veered off to Bedwyn railway station in Wiltshire. The Thames Train (whose headcode was 1K20) was the type of a 3-car

The Hinton Rail collision of 1986 is one of Canada’s worst rail disasters, occurring just on the outskirts of the Rocky Mountains in Alberta. This mass disaster was the result of a head-on high speed collision of a VIA rail Super Continental passenger train and a Canadian National freight train, leaving behind the remanence of torn apart passenger cars, shattered glass, burning chemical fumes and piles of scattered debris (Ferllini, 2012, p.170). Such a scene required the assistance of forensic anthropologists

Several efforts have been made over recent years to maintain a safe and clean environment. However, environmental pollution is getting worst and poses a major threat to the Earth. Environmental pollution is “the contamination of the physical and biological components of the Earth to such an extent that normal environmental processes are adversely affected” (Kemp, 1998, p. 129). There are five known pollution which is in the form of air, water, land, noise and light (refer to Figure 1 in Appendix

BS1003 – Organic Chemistry Practical 1 Laboratory Report Name: Tristan Chan Yew Kit, U1640436J (T8) Effects of Dichloromethane(DCM) in Extraction of Caffeine from Tea Leaves Purpose To investigate the ability for Dichloromethane(DCM), a moderately polar organic solvent, to extract aqueous caffeine molecules, originating from Tea Leaves suspended in water. Introduction Caffeine, defined chemically as 1,3,7-trimethylxanthine (C8H10N4O2), is an alkaloid that can be found in tea leaves, coffee and many

Grishma Patel Chloroplast Pigments and Colored Light Absorption Summary The purpose of executing this lab was to see how different wavelengths and colors of light are absorbed by chloroplast pigments. The goal was to see the variations of light dependant reactions of photosynthesis based on different types of light. Spinach was used by grinding it with acetone and acquire the thylakoids used in the experiment. DCIP was used in this experiment as the oxidizing agent that will turn blue to clear when

Mainly the isocynates are highly reactive and allow to forming urethane groups without any by-products formation. This isocyanates contains two or more –NCO functional groups for one molecule is called as diisocyanes or polyisocyanate respectively. The industrial important monoisocyanate compound is methyl isocyanate (MIC), majorly used to manufacturing of pesticides but this isocyanate is extremely hazardous which is responsible to Bhopal disaster, in 1984. All diisocyanate are liquids or solids in

Union Carbide is a wholly owned subsidiary of Dow chemical company which was founded in the year 1917 as the union corporation whereas before it was known as union carbide and was founded in the year 1898. In the year 1957 it was officially named as Union Carbide Corporation. The company headquarters are located in Houston, Texas, USA and it was known, as it is still known to produce bulk chemicals, Ethylene and also Ethylene derivatives which are their main products, which undergo further conversion

Background The Bhopal-Union Carbide case occurred in India where approximately 2,000 led to deaths and 200,000 resulted in injuries on the nights of December 2 and 3 in the year of 1984. The source of these loss and damages was from the deadly methyl isocyanate gas that leaked from the Union Carbide plant which was an inflammable toxic chemical utilized to produce pesticides. Unfortunately, the small huts that had resided near and were adjacent to the plant were involved in the incident as well. Apparently

1. Introduction Air pollutin is a public health concern and it has been since the discovery of fire. Incidents and episodes of air pollution have been recorded throughout the history. Air pollution is divided into two, it is the indoor air pollution and the outdoor air pollution. Indoor air pollution is produced in households or at offices by pollutants such as tobacco smoke, household products or pesticides. 2. History of air pollution Origin modern air pollution was traced to the 18th century

It all occurred on the 3rd of December back in 1984 in Bhopal, India. Due to zero of six safety systems being functional in Union Carbides ethylene producing factory more than 27 tons of methyl isocyanate and other extremely harmful gases were released into the atmosphere of Bhopal. The Union Carbide factories own documents prove that the company had taken shortcuts on safety and maintenance in order to save money and also used unproven technology
