'as lea5age is a major problem with industrial sector, residential premises and gas powered >ehiclesli5e &' compressed natural gas4 buses, cars? $ne of the pre>enti>e methods to stop accident

associated with the gas lea5age is to install gas lea5age detection 5it at >ulnerable places? The aim of this project is to present such a design that can automatically detect gas lea5age in >ulnerable

premises? In particular gas sensor has been used which has high sensiti>ity for propane 8!6 4 and butane E!0;4? 'as lea5age system consists of '(M 'lobal (ystem for mobile communications4module, which warns by sending (M( ?

#P' consists of mi9ture of propane and butane which is highly flammable chemical? It is odorless gas

due to which "thaneth oil is added as powerful odorant, so that lea5age can be easily detected? Thereare other international standards li5e "&/62, amyl mercaptane and tetrahydrothiophene which aremost commonly used as odorants? #P' is one of the alternate fuels used now days? (ometimesliquefied petroleum gas is also 5nown as #P', #P gas, Auto gas etc? This gas is commonly used forheating appliances, hot water, coo5ing, and >arious other purposes also? #P' is also used as analternate fuel in >ehicles due to soaring in the prices of petrol and diesel?

(ome people ha>e low sense of smell, may or may not respond on low concentration of gas lea5age?In such a case, gas lea5age security systems become an essential and help to protect from gas lea5ageaccidents? "mbedded system for !aFardous gas detection and Alerting has been proposed in which thealarm is acti>ate immediately, if the gas concentration e9ceeds normal le>el?

Bhopal gas tragedy was an e9ample of gas lea5age accident in India? This was world=s worst gaslea5age industrial accident
