In relation to your recent correspondence, it should be pointed out that there are no special precautions for handling leaded gasoline. The experience of the past twenty years, and the experimental work dona on this aspect of the hygienic problem, {some of which are described in the reports which are being sent to you), have demonstrated that the handling of leaded gaso line in a normal manner as a motor fuel is not to be regarded as hazardous from the viewpoint of lead absorption. There are^o however, certain features of the misuse of such gasoline which require a word of comment. Gasoline of any kind can be handled badly and carelessly in enclosed places tor the cleaning of tools, for degreasing engine parts or other machinery, for cleaning automobiles, and for similar purposes, for which it is not intended. It , can also bo introduced into barrels or tins in a manner which permits excessive spillage and evaporation. There. these conditions of/bad handling persons can be exposed to' eaessive^ ooneentrations sf^both gasqli$$ and lead vapours in the air they breathe. So long as the lead concentration in the `4,; gasoline is kept within proper limits, thert will be no important^ danger,.b|Vab-'' sorbing lead out of the gasoline through the skin. Such absorption does not ooou3:>; significantly as the result of skin contacts The important thing, therefore, is to prevent excessive spillage and excessive vapourisation of the gasoline. A second point of importance is that the leaded gasoline should not be used oontd....
