Tetramethyllead Consensus ReportsEPA Extremely Hazardous Substances List. Lead and its compounds are on the Community Right-To-Know List. Reported in EPA TSCA Inventory. Tetramethyllead Safety ProfilePoison by ingestion, intraperitoneal, parenteral, and intravenous routes. Moderately toxic by skin contact. An experimental teratogen. Experimental reproductive effects. Lead and its compounds have dangerous central nervous system effects. A flammable liquid and very dangerous fire hazard when exposed to heat, flame, or oxidizers. Moderate explosion hazard in the form of vapor when exposed to flame. May explode when heated above 90°C. Explosive reaction with tetrachlorotrifluoromethyl phosphorane. Can react vigorously with oxidizing materials. To fight fire, use water, foam, CO 2, dry chemical. When heated to decomposition it emits toxic fumes of Pb. Used as an octane enhancer for gasoline.
