1. NATURAL GAS

Natural gas is a gaseous fossil fuel consisting primarily of methane but includes significant quantities of ethane, butane, propane, carbon dioxide, nitrogen, helium, and hydrogen sulfide. Nitrogen, helium, carbon dioxide, and trace amounts of hydrogen sulfide, water, and odorants are also present in trace amounts.

Natural gas is often informally referred to as simply "gas", especially when compared to other energy sources such as petroleum product. Before natural gas can be used as a fuel it must undergo extensive processing to remove almost all materials other than methane.

The methane content can range from 87% to 96% with ethane, propane and other hydrocarbon gases making up the remainder. Due to the large methane content in natural gas, its properties are very similar. It is assumed to behave as methane.

Processed natural gas is tasteless and odorless. However, before gas is distributed to endusers, it is odorized by adding small amounts of odorants (mixtures of t-butyl mercaptan, isopropyl mercaptan, tetrahydrothiophene, dimethyl sulfide and other sulfur compounds), to assist in leak detection. Breathing natural gas in trace amounts is harmless, however, natural gas is a simple asphyxiant and can kill if it displaces air to the point where the oxygen content will not support life.

Natural gas is a flammable gas. It can be hazardous to life and property by explosion. Natural gas is lighter than air, due to its specific gravity of 0.60 which is lower than that of air (1.00), natural gas rises and tends to escape into the atmosphere. However, when natural gas is confined, such as within a building or other enclosed space, gas concentrations can reach explosive mixtures and, if ignited, result in blasts that could level and destroy buildings. Methane has a lower explosive limit of 5% in air, and an upper explosive limit of 15%. The lower and upper explosive limits are sometimes referred as lower flammable limit and upper flammable limit.

Another important characteristic for natural gas is the autoignition or ignition temperature. Natural gas autoignition temperature in air is 9980F, or 5370C, and represents the temperature at which it can self-ignite without any obvious source of ignition, such as a spark or flame.

ANY NATURAL GAS LEAK SHALL BE REGARDED AS A SERIOUS HAZARD THAT REQUIRES IMMEDIATE RESPONSE!
