Flash point 175 \u00b0F. Must be heated before ignition may occur easily. Vapors are heavier than air. Corrosive to skin but because of anesthetic qualities will numb rather than burn. Upon contact skin may turn white. May be lethal by skin absorption. Does not react with water. Stable in normal transportation. Reactive with various chemicals and may be corrosive to lead, aluminum and its alloys, certain plastics, and rubber. Freezing point about 105 \u00b0F. Density 8.9 lb / gal.
