Lead(II,IV) oxide, also called red lead or minium, is the inorganic compound with the formula Pb 3 O 4. A bright red or orange solid, it is used as pigment, in the manufacture of batteries, and rustproof primer paints. It is an example of a mixed valence compound, being composed of both Pb(II) and Pb(IV) in the ratio of two to one. [2]
The U.S. Consumer Product Safety Commission (CPSC) banned lead paint in 1977 in residential properties and public buildings (16 CFR 1303), along with toys and furniture containing lead paint. The cited reason was "to reduce the risk of lead poisoning in children who may ingest paint chips or peelings". [ 35 ]

From that month through January 2016, HPD issued more than 10,000 violations for dangerous lead paint conditions in units with children under 6, the age group most at risk of ingesting toxic paint.

The District of Columbia defines "lead-based paint" as any "paint, surface coating that contains lead equal to or exceeding 0.7 milligram per square centimeter (0.7 mg/cm2) or 0.5% by weight." [9] This is more stringent than the HUD lead-based paint standard of 1.0 mg/cm2) . Some states have adopted this or similar definitions of "lead-based ...
Lead was often mixed into oil-based paints before 1978, the year lead paint was banned for residential use in the U.S. Over time, oil-based paints will crack in a distinctive alligator scale-like ...
Similar red lead-based compounds were also widely used as a jointing compound in engineering, to form steam- or oil-tight flanged joints in pipework. Red lead in paint was not banned by the 1992 legislation [4] or by more recent EU REACH regulations [5] and the SPAB confirm it is technically available in the UK but only by special licence. [6]
