(I) A committee of prominent physicists, chemists and others was appointed to investigate the properties of TEL (tetraethyl lead). (II) The committee presently reported mild health effects from the use of lead but nothing drastic enough to justify a ban. (III) Increased ventilation and other plant improvements reduced the workplace hazard to an acceptable level. (IV) In their opinion, TEL was dangerous only in concentrated form, not when diluted in gasoline. (V) If reasonable precautions were taken and mixing was performed at distribution centres instead of at the point of purchase, there would be no cause for concern.
