Natural gas tens of millions of structures that use the fuel, the individual risk of using natural gas is very low. Natural gas heating systems may cause carbon monoxide poisoning if unvented or poorly vented. In 2011, natural gas furnaces, space heaters, water heaters and stoves were blamed for 11 carbon monoxide deaths in the US. Another 22 deaths were attributed to appliances running on liquified petroleum gas, and 17 deaths on gas of unspecified type. Improvements in natural gas furnace designs have greatly reduced CO poisoning concerns. Detectors are also available that warn of carbon monoxide and/or explosive gas (methane, propane,
Natural gas in Bolivia oil production really peaked, only to be followed by a decline in the next decade. That is when natural gas overshadowed oil and tin to become the main hydrocarbon exported by the country up to this date. Since the 1980s, the number of known reserves has increased substantially. It was during the 1990s that new major discoveries really increased natural gas production in Bolivia. “Major discoveries of natural gas since 1996 had boosted proven and probable gas reserves almost tenfold, to 48.7trn cu ft, by the end of 2004” The rise of natural gas as Bolivia’s most important export occurred
