During the manufacturing process and to a lesser degree in storage at the manufacturing facility, ethanol is pure 190 proof grain alcohol. As a pure alcohol, ethanol is placarded by the DOT as a flammable bulk liquid assigned the United Nations (US) identification number of 1170. This material is also referred to as E100. Ethanol it is shipped from the manufacturing facility, ethanol is denatured with 2%-5% natural gasoline also known as E98 and E95 respectively. A blend of 95% ethanol and 5% gasoline has been assigned a DOT/North American (NA) Identification number of E95 through E99 are also assigned the 1987 UN Identification number. Additionally,E95 may utilize the UN Identification number 3475. Ethanol is ultimately blended with petroleum gasoline to from a motor fuel in various concentrations depending on whether it is used as an additive/oxygenator or blended motor fuel. Ethanol and gasoline mixtures are assigned the Identification number UN 3475 including E11 through E99. E1-E10 blends are assigned the UN number 1203, which is also used for gasoline. Pure ethanol (E100), E95, E90, E85, and gasoline are all assigned an NFPA 704 designation of flammability 3, health1, and reactivity 0.
