 Eight combustible gas and carbon monoxide on the human body 
 A combustible gas concentrations more than an explosion under the limit case of fire (lighters, electrical switches, electrostatic, etc.) and then exploded, causing serious injury to the human body. 
 Carbon monoxide is highly toxic gas, into the human respiratory, a human hemoglobin, resulting in the body of oxygen poisoning. 
 (3) sources of carbon monoxide: 
 (1) generated by natural gas, kerosene, wood and other incomplete combustion in the furnace, water heater and other appliances; 
 (2) Some of pipeline gas and liquefied petroleum gas and other gas containing carbon monoxide.
