The metal is essentially harmless Although it can be vaporized at high temperatures, such temperatures are not usually attained in cast ing, soldering, or heat treating baths Casting and soldenng pots should have local exhaust hoods to get nd of lead vapor or lead compounds which may be carried off with volatile fluxes It is at least equally important that the surface of the lead be kept free from dross and that the dross container be enclosed under the same hood so that dross can be removed from the pot and the container covered and removed, all under exhaust Likewise, on large soldenng jobs the solder ing operation should be locally exhausted, pnmarily to prevent nose and throat lmtation from acid fluxes More important, the fur naces used for heating the soldenng irons should be exhausted because m these furnaces considerable lead is mvanably oxidized Assembly of battery plates and buming-on of the connectors should be done on gnlle-top tables with down-draft ventilation This in stallation plus regular air sampling to ensure control of contamination, and physical ex aminations to keep tiack of lead absorption by employees, can eliminate lead poisoning from battery plants The poisoning produced by inhalation of solid inorganic lead compounds commonly causes symptoms of lead colic and lead ane mia Stipple cells or other readily stained cells in the circulating blood are good indi cators of lead absorption, although not so good as the direct measurement of lead con tent of the blood or urine Urinalyses for lead can now be run routinely and cheaply and with sufficient accuracy by polarographic or spectrographic methods Lead tetraethyl and other lead alkyls are likely to be much more rapidly progressive as poisons than the nonvolatile compounds and are much more likely to attack the nervous system than to produce gastrointestinal symp 1152 toms These effects are probably typical of the volatile lead compounds, none of which is common in industry Lethanes--see Thiocyanates (aliphatic).

It does not sell red lead or litharge to the battery manufacturing indus try (Tr. 1648, Tr. 4070), and is not an important factor in the sale of lead pigments, particularly red lead and litharge (Tr. 1648).
