The recommended time-weighted average exposure limit to tetramethyllead is 0.075 milligrams per cubic meter during a 10-hour workday; the OSHA permissible exposure limit is the same value assuming an 8-hour workday. Exposure to tetramethyllead can affect the central nervous system, the kidneys, and the cardiovascular system.
