Safety is the biggest concern for firms in chemical industries that deal with dangerous gases and chemicals. These gases and chemical not only pose a threat to the lives of the people working around but also to other people and ecosystem. The side effects of such tragedies loom years after the tragedy has occurred The damaging effects of these gases and chemicals can destroy generations. Ensuring adoption of safety measures will not only help in securing the lives of the workers but also of the people in nearby areas and ecosystem on the whole.   Often the fuel and gas tanks are located in a secluded area or at an underground storeroom. It is important to keep a watch and carry out maintenance work at regular intervals. Every country has chalked out specific environmental and precautionary guidelines to be followed by corporations dealing with harmful gases and fuels. A routinely maintenance check needs to be carried out for fuel tank leak detection. It is the only way to ensure safety of the people and ecosystem. Maintenance checks at regular intervals will help in curbing major tragedies in the future. A stitch in time saves nine- that is what these routinely maintenance checks will help you in doing. Precaution is better than cure and in this case indeed it is. You cannot cure or eliminate the hazardous effects of a fuel or gas leak for years to come.  The consequences of neglecting fuel tank leak detection can haunt you for years to come. The harmful gases and chemicals impair the human body system thus posing a threat to future offspring as well. The Bhopal Gas Tragedy that occurred in the capital city of Madhya Pradesh- a state in India, in December 1984 is the perfect example for this. It is touted to be the worst tragedy in in the world. Methyl Isocyanate was leaked from the Union Carbide India Limited's plant in Bhopal on the night of 2nd December and by the morning of 3rd December, the city of Bhopal and its adjoining towns and villages were taken under the claws of methyl isocyanate.  According to the data issued by the State Government of Madhya Pradesh there had been 3,787 deaths and 558,125 injuries out of which 38,478 were temporary and 3,900 were permanent injuries.  The tragedy affected the growth of infants and triggered harmful effects in women thereby damaging their fetuses. A lot of infants born after the tragedy were being reported to be born with psychological and physical disabilities.   The tragedy could have been averted if the management had carried out regular fuel tank leak detection in the plant. The leakage in pipes triggered this worst tragedy in the world. A little carelessness can destruct thousands of lives. Therefore it is sensible to execute regular maintenance checks to treat such leaks at the first occurrence itself.
