PROPERTIES OF NATURAL GAS <br />• Lighter than air (migrates upward) <br />• Naturally odorless, colorless and tasteless <br />• Mercaptan is added — smells like sulfur or "rotten eggs" <br />Composition <br />Natural gas is a mixture of gases, including methane, ethane and <br />other chemicals. PG&E stores, transports and distributes gas <br />within a pressurized system. <br />Reactivity <br />Natural gas is stable and rarely reacts with other chemicals. There <br />are certain chemicals it does react with. In their gaseous states, <br />oxygen -enriched atmospheres, fluorine and chlorine can react with <br />natural gas creating the potential for an explosion. <br />Health Hazards <br />Natural gas can cause asphyxiation by displacing oxygen in a <br />confined area and creating an oxygen -deficient atmosphere. <br />Complete combustion of natural gas creates carbon dioxide (CO2). <br />Incomplete combustion can create carbon monoxide (CO). <br />Symptoms of Carbon Monoxide (CO) Poisoning <br />• Flu -like symptoms • Dizziness <br />• Headaches • Lethargy <br />• Nausea <br />GAS <br />
