All paints and lacquers shall be required to be labeled \"Warning (or \"Caution\" or \"Danger\"): Do not apply to toys, furniture or interior surfaces which might be chewed by children!\" unless: (a) They do not contain lead compounds in such proportion that the total lead content (calculated as Pb) of the contained solids (including pigments and drier) exceeds one per cent; or (b) no compounds of antimony, arsenic, cadmium, mercury or selenium, or of barium in a form soluble by stirring for ten minutes with five percent hydrochloric acid at room temperature, have been introduced as such in their formulation.
