Drowsiness and unconsciousness. Carry the casualty immediately to an outdoor room and keep at rest. Artificial respiration if it was directed. Medical attention. Contact with liquid: frostbite. If freezing, rinse with water. Do not remove clothing. Medical attention. propane steamer (Greek first order pion pro fat, and the chemical suffix-ano because it is the first fatty acid) is a colorless, odorless gas. It belongs to the aliphatic hydrocarbons having carbon single bonds, known as alkanes. Its chemical formula is C3H8:. Mixtures of propane steamer with air can be explosive at concentrations of 1. 8 to 9. 3 vol% propane. The flame of propane, like that of other combustible gases, should be completely blue, any part yellowish, orange or red of it, denotes poor combustion. At room temperature, is inert to most reagents but reacts for example with bromine in the presence of light. At high concentrations of propane has narcotic properties. propane steamer was identified as a volatile component in gasoline by Dr. Walter O. Snelling Office of U. S. mines in 1910. Due to the volatility of these light hydrocarbons, were known as "savages" ("wild" in English) by the high vapor pressure unrefined gasoline. On March 31, the New York Times reported on work with liquefied Dr. Snelling and that ". . a steel cylinder of this gas will be enough to illuminate a common home for three weeks. " [1]. The main use of propane is the fuel energy use. Based on the lower boiling point than butane and higher energy value per gram, sometimes mixed with it or use propane steamer instead of butane. In the chemical industry is one of the starting materials in the synthesis of propylene. Also used as a refrigerant (R290) or as a propellant in aerosols.
